[ad_1]

*VA fans rejoice when another monitor based on such a matrix appears on the market, and when the new model turns out to be also fast, then there is no limit to joy at all. Over the past year, manufacturers have not been very pleased with us with gaming *VA-models with a small diagonal, high resolution and a standard 16:9 aspect ratio. All efforts were spent on ultra-widescreen solutions, but such solutions are simply not suitable for many.


Among 27-inch *VA models, the ball continues to be ruled by Full HD solutions, which, frankly, the market is already oversaturated, and 1920 × 1080 resolution will soon turn 12 years old. But there are not so many WQHD displays on sale, so the appearance of each such new product is a long-awaited event, at least for those who follow the monitor market. One of the latest additions is the Gigabyte AORUS CV27Q. This is the first monitor of its kind for the company and, last but not least, the first on the market with a new *VA panel with 1500R curvature.

⇡#Specifications

The display in question was presented at the end of June 2019 and has not yet appeared on the shelves of Russian stores. The manufacturer’s recommended price in the United States is $469, and for Europe the figure is higher and, of course, in euros — 499. We dare to assume that the CV27Q will be offered at a price of about $420. Taking into account its features, the model has no real competitors yet, and this is only in Gigabyte’s hands.

We do not have exact data on the matrix installed in the CV27Q, just as they are not available on the Internet. A panel with a TX similar to the hero of the review is not yet known to the «corporation of good», so we just have to focus on the information given by Gigabyte itself and the results obtained during testing of the new product. We will talk about the former now, and leave the latter for the relevant sections of the article.

So, AORUS CV27Q uses 8-bit *VA-panel with a diagonal of 27 inches, WQHD resolution, and a maximum vertical frequency of 165 Hz. The matrix is ​​capable of reproducing up to 16.7 million colors, has a color gamut expanded to 90% DCI-P3 (most likely due to the use of the so-called KSF layer on top of a standard W-LED backlight), does without flicker (Flicker-Free), and the bending radius is 1500R — that is, the new screen is curved more than solutions with 1800R.

The manufacturer indicated the maximum contrast level at a standard mark of 3000:1 and viewing angles of 178 degrees in both planes. Peak brightness in HDR mode is at 400 nits, while the monitor is certified according to the VESA DisplayHDR400 standard, which promises the use of conventional edge lighting. You can not count on multi-zone!

For the CV27Q, a vertical scanning range of 48-165 Hz is declared, and AMD Free-Sync 2 with native HDR support is supported as an adaptive synchronization system. A request for official NVIDIA G-Sync compatibility has already been sent, so, given the success of Gigabyte in this field, we expect to see CV27Q in the next update of the NVIDIA G-Sync Compatible list, which already includes four models from the manufacturer.

In addition to this, Gigabyte indicated a figure of 1 ms according to the MPRT method, which makes it possible to judge not the response time of the panel, but the time the frame appears on the screen — thanks to the so-called black frame insertion using the already well-known technology with the strange name AIM Stabilizer. The minimum GtG time, according to unofficial data, is 4 ms, common for gaming (and not only) * VA displays.

In its new product, the company has updated the Black Equalizer and ANC technologies, attributing version 2.0 to them. In the first case, the impact algorithms were updated when highlighting the shadows and the adjustment range was sharply reduced, and the updated audio chip for filtering extraneous noise (active noise reduction) was distinguished by a signal-to-noise ratio (SNR) increased to 120 dB, which allows the use of high-impedance headphones with high impedance, up to 600 Ohm. The changes do not pull on a revolution, but it is good that the engineers do not stop there.

The list of monitor features continues with the familiar Dashboard function. It allows you to display technical information (voltage, temperature and CPU / GPU frequencies, fan speeds, etc.) on the screen in real time. This can be implemented using third-party software, but Gigabyte offers this feature, as they say, out of the box.

Another whole paragraph of text in the description of the monitor is devoted to the Blue Light Reducer functions (reducing the blue component of the spectrum), PbP / PiP (“picture in picture” and “picture to picture”), USB Charger (the ability to charge devices via USB). The list of GameAssist and Sidekick features continues. The first is used to display the on-screen sight, timer, counter and various grids, and the second allows you to configure the monitor through a special utility for Windows.

Of the other technologies typical of the brand’s gaming monitors, one can note the use of RGB-backlighting of the external space called Fusion 2.0 — there are no changes. To configure it, an application with the appropriate name is highlighted, but once again we note the fact that all such backlight systems look beautiful exactly until the back of the monitor is turned to the wall, which is exactly what happens most often.

The list of available interfaces for connecting the AORUS CV27Q is quite advanced: two HDMI version 2.0 and one DP 1.4. Thanks to the latter, the manufacturer talks about High Bitrate 3 “technology”, which allows organizing data transfer at a speed of 32.4 Gb / s, which opens up the possibility of trouble-free operation of the monitor with maximum resolution, high vertical frequency and HDR enabled, without cutting the operating range and depth. colors.

To connect headphones and a microphone, the monitor has 3.5 mm audio ports, and for working with peripherals there are two USB 3.0 with fast charging. There is no built-in audio system in the novelty — and this is normal, since players usually use a headset or a high-quality speaker system.

⇡ # Equipment and appearance

The AORUS CV27Q monitor comes in a fairly large and heavy box with high-quality printing and a stylish design. It contains two photos of the model, as well as a full list of features in the form of small icons.

For ease of transportation, the box is equipped with a plastic handle, and for the safety of printing and the external condition as a whole, it is placed in a regular cardboard box. This is not a feature of the test sample — it is in this form that the buyer should receive his copy, bought in a retail store.

The general list of features of the model has as many as 16 items, and one of the information stickers can be used to find out the batch number, serial number, full name of the monitor, its weight and country of manufacture (China).

The display kit includes everything you need:

  • power cable (2 pieces of different standards);
  • DP cable;
  • HDMI cable;
  • USB cable for connecting the monitor to a PC and operating a USB hub;
  • quick user guide for initial setup;
  • warranty card.

In the case of the hero of the review, the user can use any of the available interfaces, each of which will maximize the capabilities of the model. However, if you want to protect yourself from possible problems and the need for additional configuration steps, then we strongly advise you to use a DisplayPort connection and, of course, do not forget that in order to be able to set 165 Hz, you need a video card of the GeForce GTX 950 level or more modern, and the owners AMD graphics adapters simply need to make sure that the graphics card you are using has a DP version 1.2 port.

In the novelty, the manufacturer moved away from the previously adopted design concept and visually alienated the CV27Q from the previously proven brand solutions. The shapes of the body and stand have become less bizarre, the handle on the central column has disappeared, the number of decorative inserts has sharply decreased, and painted aluminum has gone down in history — now we have a stand and a central stand framed in high-quality matte plastic, the frame of which, of course, is still made of metal .

Simplifications in terms of appearance did not affect the framework of the matrix. It still uses the «frameless design» with minimal internal frames on three sides. From below, we are met by a wide plastic overlay with the AORUS logo.

The central column is attached to the body using a special quick-release fastener: to connect these parts, two guides must be brought together, the column must be installed in the grooves and lowered. On the case itself there is a standard VESA-compatible platform of the 100 × 100 mm standard, which allows you to use any suitable bracket.

The stand in the CV27Q has become simpler, but this has not affected the quality of its workmanship and the features inherited from the pioneers in the line. It is quite deep (for some reason, all manufacturers make them that way), and the width of a relatively small matrix by modern standards with a diagonal of ~27 inches is quite large. The user’s attitude to the stand will be based on how much space he has available on the table and how far away from him he is ready to place the monitor.

The cable routing system is implemented by a cutout in the central column. The manufacturer does not offer any additional accessories to hold the cables.

The ergonomics of the stand will satisfy any request: tilt (from -5 to +21 degrees) and height (within 130 mm), as well as rotation of the body to the right / left (by 20 degrees) are available. There is no possibility of flipping to portrait mode (Pivot), so the centering of the panel is perfect.

All mounting elements of the monitor, including the inside of the stand and base, are made of metal. For reliable adhesion to the work surface, four (two more places remain free) rubber legs of various shapes are used — they are good at holding the monitor in one position, including due to the rather large weight of the device.

The RGB lighting of the external space RGB Fusion 2.0 is divided into several local zones, but the illuminated logo of the CV27Q has disappeared from the list. The color spectrum of the backlight is as wide as possible. Through the monitor menu, you can select one of three modes of operation — or completely disable it. Fine-tuning and synchronization with other products can be done thanks to a separate Gigabyte application.

As in any such case, demand creates supply — and people are ready to overpay for such lighting systems even if, after installing the display on the desktop, the entire “Christmas tree” will be visible only to the wall or employees passing through the office.

The hero of the review is equipped with a matrix with a semi-matte work surface, which effectively fights glare on the screen and makes it possible to do without a clearly visible crystalline effect. By the sticker on the device case, you can check all the numbers (serial, batch number, and so on) and finally find out the approximate production date. The copy that came to us was released in July 2019.

Despite a somewhat different approach of Gigabyte designers to the appearance of the CV27Q, the quality of the materials used remains very high. The elements are processed at the highest level, the gaps are uniform along the entire length of the joints. A combination of very practical matte plastic and brushed metal effect inserts is used. The manufacturer removed the «glossy tinsel» and made his new product very strict, which is usually not typical for game models.

The monitor does not creak or crackle when twisted and repositioned. You can’t fault the painting, and the controls do without backlash. Thus, in terms of quality, the Gigabyte CV27Q does not lag behind the best representatives of the segment and even surpasses many of them. Feel free to take it! However, read the second page of the review first.

⇡ # Menu and control

The basis of the monitor control system is a five-way joystick located in the middle of the bottom edge of the case. A little higher, on the front frame, there is a power indicator with a white glow, which, if desired, can either be turned off or made half as bright.

Menu speed is high. The system instantly responds to user actions — we did not notice annoying delays. And thanks to the on-screen prompts, managing the monitor is easy and simple both day and night, in the absence of external lighting.

Among the options with quick access, the hero of the review has the following by default: select a signal source, black equalizer, go to the GameAssist and Dashboard settings. At will, the functions of all four positions of the joystick can be changed — the choice of available options is quite wide.

The appearance of the OSD menu is a design mix from what we could see in Samsung and BenQ monitors, but made in a different color, without much emphasis on any details. Everything is simple and concise. Before us is the upper block with six items that the manufacturer considered the main ones, and seven sections, the settings of which were divided into three additional sections.

The first section, Gaming, provides access to the so-called gaming parameters, including AIM Stabilizer, Black Equalizer 2.0, Super Resolution, Low Blue Light, Display Mode (built-in scaler settings), Overdrive matrix overclocking settings and the ability to activate AMD FreeSync.

Adjustments for brightness, contrast, gamma, sharpness, color temperature and color saturation are highlighted in the Picture section. Here you can also select one of the preset picture modes.

In the third section, you can find the ability to select an image source, change the tonal range when using the HDMI interface, and enable Overscan.

Extensive options for configuring the PiP and PbP functions are presented in the following appropriately titled section.

In the System section, RGB backlight settings (three modes of operation), selection of an audio signal source and functions for quick access, change of appearance and menu localization language are available.

In advanced settings, you can turn off notifications about the working resolution, change the brightness of the power indicator and the DP version, activate automatic shutdown and automatic transition to the connected signal source.

The last two sections offer to save the settings to one of the user presets and reset all parameters to factory defaults.

A slightly wider list of features is presented in a more visual form through the OSD Sidekick application, which can replace the trip to the standard monitor menu. Many consumers will find this way of controlling the display more convenient. You can download the latest version of the Sidekick utility from the manufacturer’s website.

⇡#Test Methodology


The AORUS CV27Q monitor has been tested with an updated method using the X-Rite i1 Display Pro colorimeter in combination with the X-Rite i1 Pro reference spectrophotometer, Argyll CMS with dispcalGUI and HCFR Colormeter software. All operations were carried out in Windows 10, during testing the screen refresh rate was 165 Hz.

In accordance with the methodology, we will measure the following monitor parameters:

  • white brightness, black brightness, contrast ratio at backlight power from 0 to 100% in 10% increments;
  • color gamut;
  • color temperature;
  • gamma curves of the three primary colors RGB;
  • gray gamma curve;
  • color deviation DeltaE (according to the CIEDE1994 standard);
  • backlight uniformity, color temperature uniformity (in Kelvin and DeltaE units) at 100 cd/m2 brightness at center point2.

All measurements described above were carried out before and after calibration. During tests, we measure the main monitor profiles: default, sRGB (if available) and Adobe RGB (if available). Calibration is carried out in the default profile, except for special cases, which will be discussed later. For monitors with wide color gamuts, we select the sRGB hardware emulation mode, if available. Before starting all tests, the monitor warms up for 3-4 hours, and all its settings are reset to factory settings.

We’ll also continue our old practice of posting calibration profiles for the monitors we’ve tested at the end of the article. At the same time, the 3DNews test lab warns that such a profile will not be able to 100% correct the shortcomings of your particular monitor. The fact is that all monitors (even within the same model) will necessarily differ from each other in small color errors. It is physically impossible to make two identical matrices, so a colorimeter or spectrophotometer is required for any serious monitor calibration. But even a “universal” profile created for a specific instance can generally improve the situation for other devices of the same model, especially in the case of cheap displays with pronounced color rendition defects.

⇡#Working parameters

In the Gigabyte AORUS CV27Q monitor, the manufacturer offers seven preset modes and three additional ones (Custom) for completely manual settings. In testing, we used the DisplayPort interface as the most hassle-free interface available.

By default, the basic settings look like this:

  • image mode — Standard;
  • brightness — 75;
  • contrast — 50;
  • sharpness — 6;
  • color temperature — Normal;
  • gamma — Off;
  • black equalizer — 0;
  • Overdrive-Balance;

During manual tuning (100 cd/m2 and 6500 K), the parameters took the following form:

  • image mode — Custom;
  • brightness — 11;
  • contrast — 50;
  • sharpness — 5;
  • color temperature — User (92/90/100);
  • gamma — Off;
  • black equalizer — 0;
  • Overdrive-Balance.

The user mode was used to access the full list of required parameters. After switching to it, there were no significant changes in the picture, and to obtain the required values, it was necessary to adjust only two parameters — brightness and color temperature (RGB Gain). Additionally, to our taste, we adjusted the sharpness by lowering it by one, and left the Overdrive at the default value.

⇡ # Brightness of white, black brightness, contrast ratio

The test was carried out in the «Standard» mode with the default settings.

Brightness in menu (%) White brightness (cd/m2) Black brightness (cd/m2) Static contrast (x:1)
one hundred 411 0.197 2086
90 378 0.181 2088
80 343 0.165 2079
70 310 0.149 2081
60 273 0.131 2084
50 239 0.114 2096
40 203 0.097 2093
thirty 167 0.08 2088
20 127 0.061 2082
10 89 0.043 2070
0 47 0.023 2043

The maximum brightness was at the level of 411 cd / m2and the lower value was 47 cd/m2. The contrast ratio is 2080:1 on average, which is a third lower than stated by the manufacturer. For modern *VA displays, this is quite a common occurrence, and therefore it did not cause us much surprise or disappointment.

In turn, the resulting range of backlight brightness changes turned out to be very good from all points of view. On the upper limit, the monitor slightly exceeded the value indicated by the manufacturer, and the lower limit will significantly reduce eye strain in conditions of low ambient light or its complete absence.

⇡#Results with standard settings

According to the manufacturer, the monitor is equipped with a matrix with a color gamut expanded to 90% DCI-P3. At the moment and in the next five years, compliance with this color space will be the de facto standard on the way to conquering the full-fledged BT.2020 (aka Rec.2020).

For the average consumer, this means that any content on the screen of the new CV27Q will be more saturated in color than on monitors with conventional W-LED backlighting. For games — and in other situations where high color accuracy is not important to you — this is a plus, but for working with color in the absence of certain knowledge and an individual color profile of the device — a fat minus.

At the default settings, the DCI-P3 standard was submitted to the monitor only by 85%. In comparison with the sRGB standard, the hero of the review significantly outperforms it on red, yellow, turquoise and green stimuli and slightly loses on blue shades.

The color balance of the gray wedge is significantly shifted to the cold zone, but at the same time, the stability of the CG is nowhere higher.

On the gamma curves, we see a slight discrepancy between the RGB channels and a slight drop in overall contrast. Deep shadows are distinguishable quite well, and there were no questions about the distinguishability of lights.

When assessing color accuracy, the CV27Q showed an average result, which is not surprising in the conditions of a noticeable shift in the reference points on the CIE diagram, even in comparison with the DCI-P3 set as a reference. However, it is enough to create a color profile — and half of the problems will immediately disappear.

⇡ # Results in AIM Stabilizer mode

When AIM Stabilizer is activated, the monitor’s electronics lock the brightness at 147 nits with no further adjustment possible. The contrast ratio remains at its original level of 2080:1.

The color gamut practically does not change — the insertion of a «black frame» works in a completely different direction.

The white point remained at the level of 7500 K, and with it all the other shades of gray did not move anywhere.

The gamma curves still show the same slight rise, but even if you correct it, you will not see any significant changes.

The level of deviations during verification in the Agryll CMS environment, taking into account the measurement error, remained at the original level. From this we conclude that the AIM Stabilizer in the CV27Q only affects the visual component of the display speed and does not affect its color accuracy in any way.

⇡#Results in AORUS mode

For a monitor from the AORUS series, it is a crime not to check the mode with the appropriate name. On the other hand, based on our previous review experience, the way it is set up in other models of the brand is an even greater crime. During the review of CV27Q, we gave the third and probably the last chance to fix it.

Alas, the fairy tale was not destined to come true. In AORUS mode, the image becomes unnecessarily cold, with broken sharpness and dead highlights. According to all calculations, the compliance with various color spaces has decreased.

The white point really flew into the cold zone, and with it all the shades of gray, however, retaining the initially high stability of the CG (with the exception of one point).

Everything is fine on the gray gamma curve, but as soon as we activated the decomposition into RGB components, we immediately saw the cause of indistinguishable lights (the last 4-5% of the entire range).

The changed color gamut and problems with extreme highlights seriously affected the color accuracy results in the Argyll CMS test. Two-thirds of all measured colors went into the red zone in terms of DeltaE deviations. Thus, if you are even slightly interested in color accuracy, then you should stay away from the AORUS mode.

⇡#Results in sRGB mode

When the matrix in the monitor has an extended color gamut, then the meaning of the availability and performance of the sRGB emulation mode can be traced literally immediately.

Fortunately, the Gigabyte AORUS CV27Q turned out to have this mode right out of the box, without having to wait for a new firmware. Color gamut narrows sharply to the level of most *VA displays with conventional W-LED backlighting, with a slight overshoot of sRGB on the right side of the CIE diagram.

The white point in this mode is tuned much better than in all the others, the stability of the CG grayscale is good, but the brightness is locked at 178 nits — and this ruins everything.

The gamma curves are set as correctly as possible, with a proper rise in the sRGB curve in the area of ​​​​dark shades, including for better visibility of deep shadows.

The emulation carried out by the manufacturer led to the fact that the color accuracy in sRGB mode turned out to be very high, and without the use of any third-party profile. For a newcomer to the monitor market, this is just a phenomenal result.

⇡ # Results after calibration

But let’s go back to the standard settings and make a manual correction. To do this, it turned out to be enough to reduce the brightness of the backlight and change the RGB gain to achieve the required color temperature. There was no need to change the Gamma mode, since the manufacturer set the most optimal value (this time Off, not Gamma 3, as before).

The color gamut after manual adjustment and calibration increased and we almost got close to the level declared by the manufacturer.

The white point returned to normal, and the stability of grayscale decreased slightly.

It was not possible to ideally build gamma curves (there is some dependence on the matrix warming up), but it turned out still better than with the default settings.

After applying the created profile, Windows learned about all the capabilities of the CV27Q, and together with the fine-tuned white point and gamma curves, this allowed us to achieve extremely high marks in the Argyll CMS test. Nevertheless, when working with color, you should not forget that *VA matrices have their own characteristics that negatively affect the usability: Black Crush effects, color shift along the edges of the screen, more noticeable stripes — Banding. If you do not make money on photos and videos and are faced with color processing once or twice a year, then just forget about what you read a little higher.

⇡ # Backlight Uniformity

The uniformity of the display backlight was tested after reducing the brightness at the center point of the monitor to a level of 100 cd/m2 and setting the color temperature to ~6500 Kelvin.

The picture above shows a photograph of a white field with a certain exposure compensation during shooting (in the dark) and further software processing for a more visual representation of the backlight uniformity.

On white, backlight uniformity problems are not very visible, but when looking at a gray field, they become obvious. In particular, in our copy, all the edges of the matrix are noticeably darkened, and only in the central part is the brightness at the set level.

The average deviation from the central point was 9.6%, and the maximum 23%. The result is below average. From a modern *VA-matrix, we expected something different.

Unfortunately, she could not please us in the matter of color temperature uniformity. The spread of values ​​was 771 Kelvin, the average deviation from the central point was 2.4%, and the maximum deviation was 6.4%. The color temperature gradually increases from top to bottom, which can be seen both in the course of working at the monitor and by measurements.

Now let’s look at the uniformity of the backlight and the different color effects in the case of a black box. We will do this using two photographs taken at different distances from the screen (~ 70 and 150 cm).

In the first case, the Glow effect is clearly visible in the corners, which is also characteristic of *VA matrices — it manifests itself in the form of a drop in the depth of the black field along the edges with weak spurious shades. In addition, light spots can be noted along the lower and upper edges of the panel.

If you move away from the monitor, then Glow disappears — and the picture of the depth of the black field will change dramatically. The same brightened «spots» become clearly visible — there are about 8-10 of them, as we have noted more than once with modern * VA monitors. We boldly declare that this, unfortunately, is the norm for such models, and how you relate to this depends only on you. The main thing that we have warned you: *VA-matrix is ​​not a guarantee of a perfect black field.

⇡ # Visual evaluation of the image and features of the model

⇡#Gradients quality and response speed

The Gigabyte AORUS CV27Q, according to the manufacturer, uses an 8-bit matrix, which provides good quality gradients at default settings and after manual edits. Calibration with minimal edits in the LUT of the video card slightly reduces their quality — three sharp transitions appear with weakly pronounced spurious shades in the 10-30% region.

As for such an effect as banding (sharp transitions on smooth color fills), it is clearly expressed both at the factory settings and after all the procedures performed by the user. For most modern *VA displays, this is in the order of things, and therefore we can safely say that FRC technology is still used to increase the color representation, and not in the best possible way.

Now let’s move on to the speed indicators of the display. The AORUS CV27Q monitor uses a *VA panel with a native 165Hz refresh rate (by “native” we mean that no additional overclocking is required through the monitor settings). By the way, this is the first 27-inch WQHD *VA display with a similar frequency. All closest competitors only offer 144Hz.

The hero of the review refers to gaming models (Gigabyte has no others yet), but the declared high vertical frequency is not always an indicator of a fast matrix with a low response time.

As our testing showed, AORUS CV27Q is a representative of the camp of medium-speed *VA displays, which is immediately visible in the picture above. In standard test scenarios, plumes at dark transitions turned out to be clearly visible. The monitor, of course, bypasses many 100Hz *VA-models with high resolution and surpasses absolutely all 60Hz solutions, but it is quite far from the level of high-quality gaming IPS and, moreover, TN+Film. Otherwise, when performing normal tasks on a PC, the user will be able to enjoy a significantly increased smoothness of mouse cursor movement, page scrolling, window movement, and so on.

Evaluating the quality of OverDrive factory overclocking is quite problematic, because the difference between the three main modes of the CV27Q is barely perceptible. In all cases, there are no visible artifacts, and the length of the trails is as similar as possible. In this regard, it should be recognized that there is no point in changing the Overdrive mode.

Significant changes occur only when the mode with the «insert black frame» (AIM Stabilizer) is activated. In this case, AMD FreeSync is disabled, brightness is blocked, objects become sharper, it becomes possible to read the font on a moving typewriter without any eye strain, but strong artifacts immediately appear. Whether the visual sensations of working a la “like behind a CRT monitor” are worth the appearance of such defects on moving objects is a million-dollar question. And the answer depends only on what you plan to do behind the monitor and for how long.

Speaking about the stability of the maximum refresh rate, it can be noted that we did not find any problems when testing the monitor. A special test from the TestUFO package fully confirms this — 165 Hz is real.

⇡ # Viewing angles and Glow—Effect

Now let’s look at the viewing angles of the Gigabyte AORUS CV27Q with a modern *VA panel on board.

With minimal deviations, the color shift is almost imperceptible, the image contrast remains at a fairly high level.

With strong deviations from the normal, the shadows become sharply more distinguishable, the saturation of the image on the screen slowly but surely decreases, and the contrast decreases. When viewed from the side, the picture on the monitor gives off a red-pink tint, which is typical of many solutions with an extended color gamut. The manifestation of the Black Crush effect is not very pronounced, at least much weaker than on the old *VA solutions.

The Gigabyte monitor has a black field glow effect, but it is much less pronounced than on IPS-type solutions, and causes much less irritation. Depending on the position of the user in front of a screen with a black fill (or at least with black bars at the top and bottom when watching a movie in a dark room), the ghosting and the degree of its manifestation vary markedly.

As for color images, viewing angles and other features of *VA-models are more important than Glow. When viewed from an angle, the contrast of the picture drops sharply, in some cases the effect of posterization may appear on complex color transitions, which is clearly seen in the pictures above.

⇡#Crystal effect, cross hatching, PWM

The AORUS CV27Q uses a *VA panel with a semi-matte protective surface that also covers the black inner bezels.

For most consumers, under standard operating conditions, the crystal effect (CE) will be slightly noticeable. In terms of visual impressions, the picture cannot be compared with the image from a glossy screen, but the monitor still has pretty good anti-glare properties. When the viewing angle is changed (only when viewed from above or below), the visibility of the FE does not increase. The review hero has been spared the Cross-Hatching effect.

The text rendering quality of the CV27Q is good. Such problems as on *VA-matrices with a lower pixel density, the novelty has not been identified. Smooth adjustment of Sharpness will help to adjust the sharpness to your taste. Recall that we lowered the sharpness from the default 6 units to 5 — it became quite good.

According to the manufacturer, the display has Flicker-Free backlighting, which was confirmed during our tests. At any level of brightness, SHI modulation is not used, or its frequency is several kilohertz or even tens of kilohertz. For their own eyes, users can be calm. It remains not to forget about the need to take breaks in work and not to set too high brightness in low or medium ambient light.

When activating the «black frame insertion» mode (AIM Stabilizer) at a vertical frequency of 165 Hz, we detected SHI modulation with the appropriate frequency and high duty cycle — as it should be. The load on the eyes in this case, of course, increases, but the moving objects on the screen become clearer. For a short game session, this mode can be interesting, but for prolonged work at the monitor, it should definitely be avoided.

⇡#Conclusions

Gigabyte is on the right track, providing its fans with a choice of monitors based on matrices of all major types and offering for each of them the most similar set of software «chips» and technologies on board. Buyers of AORUS series displays do not have to choose according to the principle “here it is, but here it is not”: it is enough to decide on the type of panel — and the choice is made. There is no big difference in the price of products either: TN+Film or IPS-display — Gigabyte equalized them all. An interesting approach.

With regard to the new AORUS CV27Q, we can make an unambiguous conclusion — the monitor was a success for its segment. The new *VA panel with increased curvature (1500R bending radius) did not make a breakthrough, but allowed Gigabyte to avoid significant drawbacks. The display turned out to be moderately fast, with the right approach in the field of factory settings. However, all the features of the technology used for the production of the matrix in the CV27Q also appear, and in terms of backlight uniformity it is similar to its previously released competitors.

Based on the totality of all the parameters, the hero of the review looks really attractive (especially for *VA fans), but the main question remains about the price. If it really ends up at $420, then the temptation to consider an IPS monitor with a wider range of applications and faster speeds as an alternative may be very strong.

From file server 3DNews.en can download color profile for this monitor, which we got after manually configuring and profiling.

  • adequately tuned OverDrive overclocking and high panel speed (by *VA-segment standards) without distinguishable artifacts;
  • support for AMD FreeSync adaptive sync technology (claimed operating range 48-165 Hz, NVIDIA G-Sync Compatible certification coming soon);
  • the presence of a backlight operation mode with «inserting a black frame» (AIM Stabilizer) — an analogue of ULMB / ELMB / VRB, not compatible with the simultaneous operation of AMD FreeSync;
  • backlight without flicker (Flicker-Free) and a barely visible crystalline effect;
  • good quality of fonts (additional sharpening is not required, but can be done very finely) and the absence of various spurious sounds during operation.

Disadvantages:

  • banding/posterization on complex color transitions;
  • expectedly high price compared to competitors (we focus on European prices and approximate indicators of cheating our sellers).

Might not suit:

  • simplified design and materials used against the background of previously released models;
  • no built-in speaker system;
  • quite deep stand;
  • average backlight uniformity in terms of brightness on bright and black fields (becomes the norm for modern *VA monitors);
  • the Black-Crush effect is rather weak compared to the old *VAs;
  • the contrast ratio is one third lower than the declared value;
  • when the mode with the insertion of a “black frame” is activated, the panel speed is not the highest in comparison with TN + Film and IPS (a trail with strong artifacts appears behind and after a moving object);
  • the uselessness of most preset modes and fixed brightness in AIM Stabilizer and sRGB.
