What it is: Feature that allows the monitor to synchronize its refresh rate with the input device's output and reduces stuttering and screen tearing.
When it matters: Almost every usage, but is most noticeable in gaming where constant fluctuation in framerate cause distracting artifacts.

FreeSync

The BenQ EW3270U is a 32'' 4k LED monitor with a decent picture quality. It is more suitable for darker rooms as it cannot get very bright for a bright room, but it can display deep uniform blacks thanks to the high native contrast ratio and decent black uniformity. It has good gray uniformity and a wide color gamut, but the image deteriorates when viewed from the side. It supports HDR but unfortunately, its limited brightness prevents it from delivering the creators intent, and thus it is unlikely that you will benefit from using it in this mode. It has good motion handling and low input lag with FreeSync support to keep most gamers happy.

Design

Score components: Subjectively assigned
BenQ EW3270U Design Picture
Curved : No
Curve radius : N/A
Weight (without stand) : 13.0lbs (5.9kg)
Weight (with stand) : 15.9lbs (7.2kg)

The design of the BenQ EW3270U is good. The stand supports the monitor well and it is very thin, compared to other stands in this category, allowing you to push the monitor close to the wall. Unfortunately, the ergonomics are bad and if you need to swivel or adjust the height of the monitor often, you are better off VESA mounting it. The build quality is good and will not trouble you.

Stand
BenQ EW3270U Stand picture
Width : 15.0" (38.1cm)
Depth : 8.5" (21.7 cm)

The stand is plastic with a matte finish, it is sturdy and provides good support to the monitor. There is only little wobbling if you accidentally nudge the monitor. Its design is flat but has a small inclination so you should avoid placing objects on it as they might slide off.

1.2 Ergonomics
What it is: How much the position of the screen can be adjusted to match the viewing preference of the user.
When it matters: All usages, but especially office and gaming use.
Score components:

BenQ EW3270U Ergonomics picture
Height Adjustment : N/A
Switch portrait/landscape : No
Swivel Range : N/A
Tilt Range : -15° to 5°

The ergonomics of the EW3270U are bad. You can only tilt the monitor up and down and even that is only allowed for a very narrow range. Unfortunately, you can not adjust the height of the monitor nor can you swivel left or right to show your work to a colleague. If you plan to move it often, you will be better off VESA mounting it. The input ports are pointing downwards and this facilitates access when VESA mounting the monitor.

Back
BenQ EW3270U Back picture
Wall Mount : VESA 100x100

The back of the monitor is plastic with a matte finish and it is very plain.

There is no cable management.

Borders
BenQ EW3270U Borders picture
Borders : 0.5" (1.3 cm)

The borders are thin and made out of plastic. There is a groove that goes around the monitor to provide better ventilation for the monitor's electronics.

Thickness
BenQ EW3270U Thickness picture
Thickness (with stand) : 5.2" (13.3 cm)
Thickness (without stand) : 2.4" (6.0 cm)

The monitor has average thickness without the stand compared to other monitors of this size. However, it is one of the thinnest ones, in its category, when measured with the stand. You can easily push it very close to the wall.

7.5 Build Quality
What it is: How well built and sturdy the monitor is, and how good the materials used to build it are.
When it matters: All usages.
Score components: Subjectively assigned
BenQ EW3270U Build Quality picture

The build quality is very good. There are no gaps or loose ends in this monitor and you will have no issues with it.

The BenQ EW3270U monitor has a decent picture quality. It can display deep blacks in a dark room thanks to the high native contrast ratio, and the decent black uniformity. Unfortunately, it cannot get very bright and although it supports HDR you will not benefit much from using it in that mode. The viewing angles are not good, typical of a VA panel, but it performs a bit better than most other VA-type panels. The BenQ has very good gray uniformity, and an excellent SDR color gamut although it might not be the best choice for professionals who need an even wider coverage of the Adobe RGB color space.

Great gray uniformity for the BenQ EW3270U. A little clouding is visible scattered sound the screen and the corners are slightly darker, but it should not be a problem in normal working conditions. The monitor has only small signs of dirty screen effect which can become more apparent when viewing a panning shot of large uniform areas.

Uniformity is also very good in the darker scenes as can be depicted from our 5% gray test picture. There is almost no visible clouding with the exception of the edges that look slightly brighter. Similar issues are also depicted in the black uniformity picture and are likely linked to backlight bleed. The performance of this monitor is very similar to that of the LG 32UD59-B.

Decent black uniformity for the BenQ EW3270U. There is some backlight bleed visible almost everywhere but especially around the edges and close to the corners. This is, however, the second-best score we have measured up to date along with the LG 32GK850G, and only the LG 32UD59-B was able to score marginally better.

Out of the box, the accuracy is good. The most accurate picture mode was the 'sRGB' one. With luminance set to 100 and contrast to 50, the white balance dE is above the 3.0 mark and we expect most people to notice some gray inaccuracies. The color dE is below 3 and thus the color inaccuracies are harder to spot. The color temperature is on the warm side and the monitor has a red-yellowish tint. Finally, the gamma is very close to the average dE of 2.2 target and follows the target curve very closely.

After calibration the color accuracy on this EW3270U BenQ monitor is remarkable. White balance dE and color dE are lowered to values that are impossible to spot any inaccuracies without a colorimeter. The color temperature is corrected and now is very close to the 6500K target and the gamma has an average of 2.2, following the sRGB target closely. We performed our calibration in the 'User' picture mode.

The monitor has two HDR modes, the 'HDR' and the 'Cinema HDR'. Cinema HDR is just slightly better due to the better white point, but in general, they perform very similarly since their EOTFs are almost the same
The result is very similar to LG32UD99.

The handling of reflections on the BenQ EW3270U is good. Reflections are diffused across the screen by the semi-gloss finish and this reduces their intensity. The monitor has no issues with reflections except when in a very bright room.

7.9

Motion

Score components:

Very good motion handling for the BenQ EW3270U with a fast pixel response time, a flicker-free backlight, and support for FreeSync variable refresh rate. Unfortunately, the 60 Hz native refresh rate and the narrow FreeSync range are not an attraction to competitive gamers.

8.5 Motion Blur
What it is: The performance of the pixel response time. Poor response time causes trails to follow moving objects. Response time is one of a few sources of motion blur.
When it matters: When there's fast movement on screen, such as during video games and sports.
Score components:

Fast pixel response time. Fast-moving content has only a small blur trail. Most of the blur in the photo is due to 60 fps persistence; only a faint ghosting/smearing trail can be seen following the logo, which is great. We prefer not to use any of the overdrive settings and leave the 'AMA off' since the other two options add noticeable overshoot.

7.5 Image Flicker

The BenQ EW3270U is flicker-free, as it does not use PWM to dim the backlight. Unfortunately, it does not have an option to introduce flicker to make motion look crisper, but it is common for 60Hz monitors to lack this.

7.8 Refresh Rate
What it is: How frequently the monitor can refresh and show new frames, and whether it can vary its refresh rate in real time using technologies like G-sync and FreeSync.
When it matters: Mostly for gaming, but does provide a little better motion during normal usage.

Unlike our other photographs, this picture wasn't taken under a controlled environment, so do not draw conclusions from it.

This is a good monitor that unfortunately loses many points due to its bad ergonomics. See our recommendations for the best monitors we've tested so far and the best large monitors.

LG 32UD99

The LG 32UD99 is much better than the BenQ EW3270U for most people, unless the  deeper blacks of the BenQ due to the VA panel are of great importance. The LG 32UD99 has an IPS panel with significantly wider viewing angles so you can share your work with you colleagues more easily and at the same time the much better ergonomics allow you to position the monitor to your liking with ease.

Samsung CHG70

The Samsung CHG70 is better than the BenQ EW3270U. The Samsung CHG70 has much better ergonomics and local dimming support to enhance picture quality and can get brighter in HDR. The CHG70 also has a faster pixel response time, lower input lag and faster refresh rate all of which are great news for gamers. The BenQ EW3270U is larger with better resolution and marginally better black uniformity.

LG 32GK850G

The BenQ EW3270U is slightly better than the LG 32GK850G. The BenQ EW3270U supports HDR content and has a full 4k resolution. The LG 32GK850G, on the other hand, has much better ergonomics so you can position it to your liking with ease, and a fast pixel response time that leaves a small motion blur. The LG has a much faster refresh rate and a lower input lag to please even the most demanding gamers.

Dell U3219Q

The Dell U3219Q is better than the BenQ EW3270U for most people. If you care more about dark scene performance, then the BenQ EW3270U is a better choice as it has better contrast and better black uniformity. The BenQ EW3270U is also flicker-free. On the other hand, the Dell U3219Q has much better ergonomics so you can place it comfortably and much better viewing angles so that the image remains accurate when you view it from the side.

Samsung CF791

The BenQ EW3270U is significantly better than the Samsung CF791. The BenQ EW3270U has better resolution and can display more detail on its screen and it supports HDR content. The EW3270U also has lower input lag and more uniform blacks. The Samsung, on the other hand, has a slightly faster pixel response time that leaves a smaller motion blur, and much better ergonomics to help you position it to your liking.

BenQ EL2870U

The BenQ EW3270U is better than the BenQ EL2870U. The EW3270U has a much better native contrast ratio, and better black uniformity. The EW3270U also has better HDR performance, as it can display a wide color gamut.

7.4Mixed Usage
Score components:
This is a decent monitor for mixed usage. It is more suitable for dimmer environments as it cannot get very bright, but can display deep uniform blacks. The monitor supports HDR, but because of the poor brightness, you will not benefit using it in this mode. Its large screen size and 4k resolution allow you to see a great deal of detail when you are working or gaming with this monitor. It can handle reflections well so you should not worry about placing it in a room with many small light sources. Unfortunately, the bad ergonomics can make it hard to find a comfortable position.
The BenQ EW3270U is a decent monitor for office use. It has an excellent 4k resolution and a large 32-inch screen size which allows you to see every little detail of your work. If you wish to share your work with a colleague, the poor viewing angles will not allow them to enjoy the same picture quality without swiveling the monitor to face them directly. Unfortunately, the bad ergonomics cannot help either, so if you regularly work in teams then you might want to VESA mount it.
The BenQ EW3270U is a good monitor for playing games. It has a low input lag and supports FreeSync which will make those with Xbox One S/X or NVIDIA graphics cards happy. It is fairly large and has an excellent 4k resolution that can display every little detail of your game. It has an ordinary 60Hz refresh rate and a fast pixel response time which only leaves a small blur trail in fast-action scenes. Unfortunately, the ergonomics will not make it an easy task to position the monitor to your liking.
The BenQ EW3270U is a good monitor for multimedia usage. It has a large screen with ample 4k resolution that is capable of displaying 4k content without downscaling. It has a low input lag and thus it is very responsive to your actions. Unfortunately, when you view it from the side the picture quality deteriorates. It has good reflection handling but you will have a hard time placing it in a comfortable position since the ergonomics are bad.
The BenQ EW3270U is a decent monitor for media creation. It is a large monitor with a great 4k resolution which makes it comfortable for professionals to work on. However, the ergonomics are bad and it might be a good idea to VESA mount it for better flexibility and at the same time to resolve the issue of poor viewing angles. It has good gray uniformity and excellent coverage of the DCI-P3 color space. Unfortunately, the coverage of the Adobe RBG color space might not be enough for professionals in the publishing or printing industries.
This monitor is decent for HDR gaming. It has a high native contrast ratio and decent black uniformity so it can display deep blacks in a dark room, but lacks a local dimming feature to further improve performance. It also has a low input lag which makes it very responsive to your actions. Unfortunately, the monitor cannot get very bright in HDR and its performance is far from the creators intent. It has good size and resolution, but very poor ergonomics.
