Consumer demands are growing every year, the possibilities of desktop displays are expanding, and the standards adopted in the 90s are quietly and peacefully living out their years, during which there should be a cycle of updating old monitors to more advanced solutions. Of course, according to the best estimates, it will affect less than half of all consumers in the world, but even this will be enough to boldly say — “Goodbye old sRGB! We’re moving on!»

In order to achieve high color gamut figures, manufacturers are less and less using complex and expensive backlight systems. Modern panels with additional layers are coming to the masses — deposition of “nano-particles” and “quantum dots”, which just allow you to get closer to the same DCI-P3, and sometimes slightly surpass it. Cheap, cheerful and, no less important, effective. Manufacturers rejoice at the money saved, and users are happy with the riot of colors on the screen of a new acquisition, because they do not yet know that such abilities will only add color problems.

So the first time will be with any available model that does not have advanced electronic filling. More serious solutions, as before, will offer various modes of emulation of the usual color standards, and therefore they can be safely taken for growth right now. We will consider one of these displays today — meet the new 4K monitor BenQ PD2720U, which sets the bar high in the segment of semi-professional solutions.


The PD2720U monitor belongs to the Professional Design (PD) line of designer monitors, and its full name sounds like DesignVue PD2720U, which emphasizes the orientation of the model. The novelty supports AQCOLOR (Accurate Color Reproduction) technology for full compliance with modern color standards. Among BenQ models, this is the second 4K IPS solution with extended color gamut, positioned below the professional SW271, but in some respects superior to it. Surprisingly, in terms of price, the difference between the models is not very serious — at the time of testing (beginning of July 2019), the new product is offered only $ 5-00 cheaper than the older comrade, which, in terms of spending over $ 620, is not a very big loss.

According to confirmed data, the BenQ PD2720U model uses an AH-IPS matrix (refers to IPS-type) manufactured by LG Display, model LM270WR4-SSA1. This is a 10-bit solution using the FRC method to increase the number of playable halftones to 1.07 billion. The panel size is 27 inches, the working resolution is 3840 × 2160 pixels (4K|UHD standard), the aspect ratio is 16:9, and the final pixel density is 163 ppi. The last figure says that the monitor will delight you with high-definition images on the screen and will create an obvious need to use the rather problematic Windows OS scaling system for software without embedded support for HiDPI displays. However, both features apply not only to the PD2720U, but also to all its competitors, and therefore if you are still ready for such changes in your life, then just forget about it and feel free to buy the model you like.

Claimed maximum brightness is 350 cd/m2, static contrast ratio — standard 1000:1. From the point of view of speed indicators, the monitor does not set records (but there is no need for such): 60 Hz, 5 ms according to the GtG method and the lack of support for any adaptive synchronization system is the norm these days for devices of this kind.

The panel used hit the market in early 2017, and then such advanced options used GB-r-LED backlighting, which allowed the PD2720U to reach the level of 100% compliance with sRGB and AdobeRGB standards, as well as 96% DCI-P3. To reduce the load on the eyes of consumers, it dispenses with SHI modulation (i.e., Flicker-Free), and as an additional level of protection, the “technology” of the Low Blue Light backlight is used.

The PD2720U monitor has the familiar special CAD/CAM and Animation preset modes that enhance the image contrast for better elaboration and more comfortable work with thin lines. For specialists in the field of CT-MRI, DICOM Mode is intended, and for work in poor lighting, it is proposed to use Darkroom Mode (“Dark Room” mode) with reduced brightness and visual contrast for better visibility of dark shades and less strain on the eyes, as well as Low Blue Light with a «warm» picture and four sub-modes of operation.

To the factory-calibrated sRGB mode, two no less significant presets were added — AdobeRGB and Display P3 (DCI-P3 adaptation to the usual gamma curve), also with precise factory settings.

In accordance with modern requests, the monitor has support for the HDR10 standard and its emulation mode for content without appropriate metadata. It should be recalled here that full-fledged HDR is possible only on OLED panels with pixel-by-pixel brightness control, and in the case of the hero of the review, this is only a software refinement of the picture (gamma 2.4-2.6 and optional, but possible automatic control of brightness and contrast over the entire panel area) without fully working with metadata embedded in native HDR content.

The new BenQ uses a modern “frameless” design, but the wide bottom bezel with a plastic overlay is still with us. The unit with ambient light and presence sensors is not used.

The exterior of the model has seriously changed against the background of other solutions of the manufacturer, and the ergonomic stand pleases with all available degrees of freedom. In PD2720U, the control system has been changed — both in principle and in the location of three physical keys and a five-way joystick. In addition to it, it is possible to use a remote control unit (Hotkey Puck G2) with quick access keys and a smooth adjustment wheel connected via the mini-USB port on the device case.

The image of a modern monitor completes the set of interfaces used for connection: two HDMI 2.0 (for seamless connection of set-top boxes with HDR support), Display Port 1.4 and two USB Type-C (Thunderbolt 3) with support for creating a chain of monitors (Daisy-Chain) and charging connected devices power up to 65 watts. Those who work with several computers connected to one display will like the KVM switch function, which allows one set of keyboard / mouse to control two working devices. True, without installing software in the face of Display Pilot, performance is not guaranteed.

To work with peripherals, the monitor has two USB 3.1 ports and a 3.5 mm audio output for connecting headphones or an external speaker system. There is also built-in acoustics, but very simple — a stereo system with a total power of 4 W cannot produce high volume and high-quality sound. On the other hand, she is not here for this, but in order not to buy separate speakers for playing all sorts of working sounds, light background music without any quality requirements or communicating via Skype, she is quite enough.

⇡ # Equipment and appearance

The BenQ PD2720U monitor comes in a small box with a simplified design — there is no photo, no listing of the model’s features. There is no plastic carrying handle — only cutouts in the cardboard on both sides.

The sticker on the box contains information about the main technical characteristics of the display. The date (April 2019) and place of production (China) are also indicated. The version of our instance is 00-006-AL.

The display kit includes everything you need:

  • power cable;
  • HDMI cable;
  • cable DP -> miniDP;
  • USB Type-C cable;
  • USB Type-B cable for connecting the monitor to a PC;
  • plastic element of the cable management system (back cover);
  • external control unit Hotkey Puck G2;
  • CD with drivers and user manual;
  • report with factory calibration results;
  • quick user guide for initial setup;
  • instructions for safe handling of the device;
  • service information.

The factory calibration report is contained in an elegant black envelope. The buyer will be presented with an A5 sheet with color accuracy results in an unknown mode, with a digital connection, with an activated sRGB gamma and a Display P3 color gamut (we assume that we are talking about a preset mode with an identical name), despite the fact that deep tuning in The PD2720U is exposed to as many as three presets. We will not say that each instance is subject to individual adjustment, but the fact that BenQ uses a selection of the most successful and stable matrices in terms of quality is quite likely.

The appearance of the novelty gives an understanding of the direction in which the design of the company’s promising devices is changing. PD2720U is made in a new style: black plastic was replaced with dark gray, the entire back of the case is flat, without unnecessary drops and transitions, the stand and part of the central column are made of brushed aluminum. Strictness is preserved at the core, and minimalism is “overclocked to the maximum”, which, however, did not prevent the body from being thick enough by modern standards.

The monitor stand is optimal in size for the used screen diagonal. Its thickness is reduced by at least half, but this did not affect stability and, especially, tactile sensations. It is heavy, and aluminum pleasantly cools hands. The central column has also undergone a change. The height adjustment mechanism is built in between its two parts. The upper casing, as opposed to the lower part, is made of matte plastic with brushed metal imitation.

The cable management system consists of a plastic hook on the movable part of the B-pillar and a rear cover that hides the connection interface area.

The central column is attached to the monitor in just a couple of seconds and detaches just as quickly — just press the button below. Holes for VESA-mounts are slightly recessed into the case, but in most cases this will not create problems.

The ergonomics of the stand will satisfy the needs of all consumers without exception. You can change the tilt and height, as well as rotate the case.

There is the possibility of flipping to portrait mode (Pivot, only in one direction). Because of this, the centering of the hull was not affected, the play in the horizontal area is not more than one degree in both directions.

All mounting elements of the monitor, including the inside of the central column and the base of the stand, are made of metal. For reliable adhesion to the work surface, six 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 display is equipped with an AH-IPS-matrix with a semi-matte work surface, which should fight not only glare on the screen, but also the annoying crystal effect.

On the sticker on the body of the device, you can check all the numbers (serial, batch number, and so on), the date and place of production.

All interfaces for connection are located in the back of the case, on one block, and are directed downwards. Thanks to the ability to flip the case to portrait mode, there are no problems with connecting cables.

Built-in speakers familiar from other models with a total power of 4 W are located behind a plastic mesh in the upper part of the case. The sound quality, unfortunately, is far from desirable — it, like the maximum volume, is at a level below average. Nevertheless, the built-in speaker system is quite capable of replacing some simple speakers for $500-130.

The PD2720U monitor is beautiful, refined, strict and pleases with high workmanship. The quality of the materials used and their practicality are not satisfactory. The elements are processed at the highest level, the gaps are uniform along the entire length of the joints. Don’t worry about the paint either.

The novelty does not creak or crunch when twisted. Changing the position of the body on the stand is «like clockwork». The BenQ PD2720U looks more expensive than many of its predecessors and is obviously the right direction for the manufacturer’s monitor line design. More metal is good!

⇡ # Menu and control

The PD2720U control system is based on a five-way joystick and three keys (one for power and two for quick access) located on the back of the case on the right side.

The power indicator passes through a transparent plastic insert along the bottom edge. An additional means of controlling the monitor is a separate unit connected via mini-USB. It is well made and pleasant to use. Thanks to it, you can quickly navigate through the menu, switch the selected modes, interfaces, adjust the brightness, contrast or volume, as well as go to the settings for quick access functions.

The programmers worked on the animation and its speed. All actions related to setting up the display occur quickly and comfortably, without delay. There is no difference in convenience between the built-in control system and the external unit — you can quickly get used to both options and use the one that you like the most in the future.

When you press the joystick, the navigation menu block is displayed on the screen. By default, you can quickly go to the brightness and contrast settings, remove the navigation block and go to the main menu. Two physical keys provide quick access to three selected modes and connection interfaces. In the future, the user can select the necessary items for various functions with quick access.

The design of the main menu of BenQ monitors for working with color has not changed for a long time — we have the usual color scheme and 2-4 sections, depending on the selected section and submenu. In the case of the PD2720U, the main menu has seven sections. Let’s go through each of them.

The first one allows you to select the signal source and configure the PiP|PbP functions.

The section called «Picture» contains settings for brightness, contrast, sharpness, dynamic contrast, scaler and Overscan.

In the next section, most of the color settings are available only in the user mode (User). You can also select one of the remaining Picture Modes, activate the DualView mode with a choice of the second display mode, set the color temperature (three presets and a manual preset) and the degree of overclocking of the panel.

Of the interesting things, six-axis corrections for hue and saturation are presented, but there is no sense in them in the absence of measuring instruments and understanding of what you are doing.

You can set the volume level of the built-in speaker system or turn off the sound completely in the fourth section with the appropriate name.

The next section is KVM Switch to quickly configure the corresponding function.

In Custom Key, the user can select the functions of the keys quick access on the monitor body and on the additional control unit. The choice is quite wide, everyone will definitely choose the most optimal option for themselves.

The System section offers to set the menu localization language (there is Russian with adequate translation), configure the interface modes, turn off DDC / CI, activate automatic power off and set up reminders to take work breaks.

In addition, you can view basic operating information, display color settings, and reset all settings to default.

To access the service menu, you must press the five-way joystick at the moment the monitor is turned on. Thus, we confirmed the model of the matrix used in the PD2720U, found out the versions of the built-in scaler and firmware, as well as the operating time. Obviously, the average user has nothing to do here.

⇡ # Testing methodology

The BenQ PD2720U was 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 60 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 BenQ PD2720U monitor, the manufacturer uses as many as fifteen (!) preset modes and one additional one 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:

  • picture mode — M-Book;
  • brightness — 100;
  • contrast — 50;
  • sharpness — 6;
  • color temperature — normal;
  • AMA — High;

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

  • image mode — User;
  • brightness — 15;
  • contrast — 50;
  • sharpness — 5;
  • Colour. temperature — def. user (100/97/93);
  • gamma — 2.2;
  • AMA — High;

The user mode was used to access the full list of required parameters. After switching to it, the white point lost its former accuracy of settings, I had to change the gamma mode, RGB Gain values ​​and, of course, reduce the brightness to the optimal value. The color gamut was set at the native level for the matrix used — wider than AdobeRGB. The degree of overclocking AMA (Overdrive) did not change, since the optimal value was chosen by the manufacturer by default.

⇡ # Brightness of white, black brightness, contrast ratio

The check was carried out in the «M-Book» mode with the default settings.

Brightness in menu (%) White brightness (cd/m2) Black brightness (cd/m2) Static contrast (x:1)
one hundred 378 0.373 1013
90 345 0.34 1015
80 314 0.309 1016
70 282 0.277 1018
60 250 0.245 1020
50 217 0.213 1019
40 184 0.18 1022
thirty 150 0.146 1027
20 115 0.112 1027
10 80 0.077 1039
0 44 0.043 1023

The maximum brightness was at the level of 378 cd / m2and the lower value was 44 cd/m2. The contrast ratio is 1020:1 on average, which fits into the level declared by the manufacturer and is an average result for an IPS matrix.

The resulting backlight brightness range turned out to be ideal from all points of view. At the upper limit, the monitor exceeds the value specified by the manufacturer, and the lower limit will allow you to minimize eye strain in conditions of low ambient light or its complete absence (but we strongly do not recommend doing this).

⇡#Results at standard settings (M-Book mode)

The monitor has a matrix with a wide range of backlighting — the native color gamut of the PD2720U is wider than most modern monitors designed to conquer the DCI-P3 space.

The M-Book mode is selected by default, which surprised us a lot, because it cannot boast of fine tuning.

The color gamut in it is maximum, without any emulation.

The white point is far from ideal, and all shades of gray along with it lie in the area of ​​cold tones with a slight spurious tint. Gray CT stability is generally good, but darker tones let them down.

There is virtually no divergence of the channels of the gamma curves, but based on their position, we can conclude that the picture on the screen is displayed with excessive contrast, without distinguishing details in the shadows. In addition, there are problems with sharpness — it is not clear why it is increased.

In the case of the PD2720U, for each of its modes, we selected the closest color profile as a reference. For the M-Book, it was AdobeRGB, but it didn’t help much. What is the average, what is the maximum deviation of DeltaE94 turned out to be in the red zone.

⇡#Results in HDR Emu mode.

The BenQ monitor has not only support for HDR10, which, due to the lack of a multi-zone backlight system, is not very effective, but also a special HDR emulation mode. It was created to simulate «dynamic range expansion» when playing content without HDR support.

In this mode, the monitor works at its maximum, the color gamut is not cut off and even becomes a little wider than with the default settings.

The white point here is tuned much better, and the stability of the CG grayscale is maintained at its original level.

We already know the approach to setting up HDR emulation. The manufacturer significantly increased the contrast in deep (killing their visibility) and medium shadows and increased the brightness in the medium hues and highlights. The result is an almost classic S-curve, which gives «brightness and color» to the picture on the screen. To put it bluntly, this mode has nothing to do with real HDR.

In this case, you should not be surprised at the increased color rendition deviations. The difference could be even higher, but the PD2720U took pity and did not overdo it with «tuning».

⇡#Results in User mode and after manual tuning

Now let’s look at the User mode, when you switch to which all color settings open, evaluate its factory settings and carry out manual adjustment in order to achieve a brightness of 100 nits, a color temperature of 6500K and a gamma of 2.2. Recall that in it the color gamut is still the maximum possible.

In both cases, the monitor gives out all the potential inherent in it in terms of color reproduction capabilities.

The white point and gray balance are badly adjusted, but manual adjustment quickly fixes this.

The gamma 2.6 accepted by the manufacturer as the norm looks strange, but this is quickly corrected by setting the gamma 2.2 mode, after which all problems with the contrast of the picture quickly disappear.

Not surprisingly, after such changes and using the created profile, the monitor was able to demonstrate a high result. Only one of the proven color patches spoils it. At first we thought it was a bug, re-profiling and testing five times didn’t show anything new. It looks like the monitor is waiting for a new firmware (we saw this on one of the Dell monitors, where the problem was fixed by the new firmware) or you need to “chemize” with manually adjusting the hue and saturation of the turquoise color.

⇡#Results in sRGB and AdobeRGB modes

Next we check are two factory-configured emulation modes for the main color standards: sRGB and AdobeRGB. In each of them, the user can only adjust the brightness and sharpness, and therefore it is expected that all other parameters should be adjusted as accurately as possible right out of the box.

Emulation of the color gamut of both standards is above average. A slightly problematic area is the zone with red color.

The white point is set very accurately, you can easily forget about the need for manual adjustment (and you can only do this through LUT video cards). There are no particular questions about the stability of the grayscale DT, especially in the AdobeRGB mode.

Gamma curves are set exactly to both standards. In sRGB, the visibility in deep shadows is increased, and in AdobeRGB, the curves sagged slightly under the reference in mid-tones.

Given the imperfect emulation of color spaces, the results obtained in Argyll CMS, we can say are at least very worthy. If you look from the position of an ordinary consumer, then such results can be attributed to high ones and you can immediately forget about the need to make manual adjustments. Reduce the brightness to a comfortable level and do not know the troubles, and the BenQ PD2720U will help you with this.

⇡#Results in DCI-P3 and Display P3 modes

The original DCI-P3 standard prescribed a gamma of 2.6 on average, which significantly increases the contrast of the resulting picture, however, someone from Apple, who first introduced this color space to the consumer sector, felt that the expanded color gamut should be crossed with a more standard gamut 2.2, and they called the resulting «sandwich» Display P3. Thus, between the two standards there is a large gap in the resulting picture and this is the first thing to remember.

The BenQ PD2720U monitor, you guessed it, has both emulation modes.

The color gamut in them differs, but there is no fundamental difference. Visually, it is noticeable only by the set brightness — in DCI-P3 it is much lower.

The white point in Display P3 is tuned much more precisely than in DCI-P3. The same, but with a smaller difference, happens with gray balance.

DCI-P3 mode complies with the declared standard with increased picture contrast. In turn, Display P3 looks much more presentable and familiar (one superimposed on another) and will suit the vast majority of those looking at the screens of their latest iPhones.

However, despite the various deviations, both modes are well-tuned factory presets. If you are interested in modern standards, then feel free to set DCI-P3 or Display P3. If the white point (a value that depends on the DH sources of external illumination) is important to you, then you should consider only the second mode.

⇡ # 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 backlight uneven compensation system is not provided in the PD2720U monitor.

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, the backlight seems worthy and, frankly, this is not an optical illusion, but confirmed facts (even if you can’t tell by the shades of gray).

The average deviation from the central point was 10.9%, and the maximum 20%. The dimming of the screen is quite even, without sharp transitions, and therefore does not cause irritation.

With color temperature uniformity, our BenQ PD2720U is even better. The spread of values ​​did not exceed 380 kelvin, the average deviation from the central point was 1.7%, and the maximum deviation was 4.4%. The only problematic part of the screen is the upper right corner. Otherwise, the result is very good and it is unlikely that anyone may have complaints about such uniformity of the DH illumination.

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).

From the point of view of the angular Glow-effect, the monitor under study showed quite the usual result for an IPS-matrix — four “illuminated” corners with weak spurious shades. The size of the «flares» depends on the distance to the screen — the closer, the larger they are.

When moving away from the screen, Glow completely disappears — and we see a fairly uniform black field for an LCD monitor with any type of matrix, demonstrating the real state of affairs — uniformity on a black field, excluding Glow. Flare in our copy is minimal, mainly expressed along the edges of the panel in thin intermittent stripes. You should not count on something better, since the example we have shown is close to ideal, and not only in the segment of IPS solutions, but also in all other types of panels.

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

⇡#Gradients quality and response speed

The used 10-bit (with or without FRC — this will remain a mystery) matrix in the PD2720U was able to demonstrate outstanding uniformity of gradients in all preset modes and after editing operating parameters through the OSD menu in user mode. A good factory setting allowed us to do only profiling, without making changes to the LUT of the video card, so that the quality of the gradients remained at its initially high level. By the way, this is one of the most important advantages of BenQ monitors compared to their direct competitors, which often require, albeit not large, LUT edits.

Let’s supplement the above with the fact that when switching the output color depth from 8 to 10 bits in the video card driver, no changes visible to the eye occur. The quality of gradients in Photoshop and, moreover, TFTTest remains at the original high level.

Now let’s move on to response time. The matrix speed in the PD2720U is quite typical for high-quality IPS-type solutions with a maximum vertical frequency of 60 Hz and does not differ from that of most competitors. Or, to put it another way, it’s definitely not worth building high hopes, and you shouldn’t even think about comparing it with gaming solutions. The novelty will immediately be an outsider.

The default value of overclocking is optimal. Translation of AMA (OverDrive in the general sense) to the «Off» position increases the visual visibility of trails, while image artifacts are absent in both cases. In the Premium mode, the trails become less noticeable, but at the same time, clearly distinguishable image artifacts appear and this is already bad. So the right choice is obvious here.

⇡ # Viewing angles and GlowEffect

In terms of viewing angles, the monitor in question is not much different from other 27-inch 4K models with IPS-type panels, demonstrating a high level of picture stability at working viewing angles.

With minor changes in the horizontal plane, the picture on the screen does not change at all. If you increase the angle to 30-45 degrees, then the image becomes a little less contrast, the saturation of some colors slightly decreases, the shadows are slightly brightened — nothing unusual. With changes in the vertical plane, the picture on the screen deteriorates faster and stronger. The extreme areas of the screen, in particular, the corners, change their appearance especially strongly.

The tested monitor is not spared from the Glow effect, since it is built on the basis of an IPS-type matrix. Depending on the position of the user in front of the screen with a black fill, the stray tint and the degree of its manifestation vary greatly.

The Glow effect also manifests itself in color images, but to a much lesser extent and weaker than in many other IPS monitors, without showing any clearly visible spurious tint, which is for a monitor with GB-r-LED backlighting and extended color coverage is amazing. However, much depends on the color range and brightness of the picture itself on the screen. So with your own checks (on other pictures), the result may differ.

⇡#Crystal effect, cross hatching, PWM

The BenQ PD2720U monitor uses a matrix with a good semi-matte protective surface.

The picture on the screen is pleasing to the eye. The crystalline effect is barely noticeable, many will not see it at all. When you change the viewing angle, its visibility practically does not increase. This display model is completely free from the Cross-Hatching effect.

We had no complaints about the display of small elements and drawing text of various sizes, but only when setting Sharpness — 5. If you look at the text at standard display settings (M-Book mode, sharpness 6), it quickly becomes clear that something it’s not like that here.

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.


Every year the quality of BenQ monitors is growing (personal opinion of the author and work experience, not theory and conclusions from reviews on the Internet), the approach in many issues is being revised (more often in a positive direction for consumers), and the number of successful models is increasing. Of course, there are misfires, but this is par for the course for every manufacturer, even one as large and experienced as BenQ.

The PD2720U monitor, without a doubt, turned out to be of high quality and, of course, a worthy purchase candidate. There are questions about its positioning and the set price, because SW271 looms on the horizon with hardware calibration, advanced electronics with a similar or even identical matrix, but without Thunderbolt 3. Most likely, the manufacturer offers to choose between a more modern approach with a large number of fairly finely tuned modes and not very useful light shield with open access to a 14-bit 3D-LUT.

Also, be aware that 27-inch 4K IPS displays start at $100, but you pay extra for extended color gamut that isn’t achieved with an expensive backlight system, and factory-tuned precision in special modes. If you have any doubts about the need for DCI-P3 and AdobeRGB color spaces, then you should think carefully — is it worth overpaying $ 30-400 or is it better to take a high-quality 4K display with a standard color gamut, such as the PD2700U we previously tested.

From the file server, you can download the color profile for this monitor, which we received after manual configuration and profiling.

Might not suit:

  • 4K resolution and the need to use the still problematic scaling system in Windows (it only gets a little better every year);
  • lack of ambient light and presence sensors — many are already accustomed to seeing them in every second BenQ model;
  • lack of a backlight compensation system and access to the built-in LUT monitor;
  • poorly configured M-Book mode — a very strange choice as the default mode;
  • panel speed, in fact, leaves much to be desired (for a 60 Hz display);
  • the results of uniformity in terms of brightness on a white field are below average (depending on the specimen);
  • Glow-effect is fully present — still with us …
