The Acer G257HU Smidpx is a decent 1440p IPS monitor with decent picture quality and great peak brightness. The IPS display delivers good viewing angles but has very bad black uniformity. It has excellent low input lag, but gamers will be disappointed by the limited 60Hz refresh rate and lack of VRR.
Decent monitor for mixed usage. It has an excellent contrast ratio, but very bad black uniformity so it isn't a good choice for a dim room. The stand is mediocre and has almost no ergonomic adjustments, and it can't be VESA mounted. The IPS panel delivers good viewing angles and excellent gray uniformity.
Decent monitor for use in an office setting. It has wide viewing angles and a high 1440p resolution, good for multitasking or sharing your work with others. The stand is mediocre and has very few adjustments so it is hard to place it in an ideal viewing position. Great peak brightness and good reflection handling make it a good choice for a brighter room.
The Acer G257HU Smidpx is a decent monitor for gaming. It has decent motion handling, with a great response time and no flicker. It has excellent low input lag, but gamers might find the 60 Hz refresh rate too low and will be disappointed by the lack of FreeSync or G-Sync. The 1440p resolution is a great balance of higher detail without needed a top-end graphics card for most games.
Decent for watching videos and movies as long as you are in a bright room due to the horrible black uniformity. It has good viewing angles and good reflection handling, so you can easily share a video with multiple people.
Decent monitor for creating media. The 1440p resolution makes it easier to multitask or to see more of high-resolution files. It has excellent color accuracy once calibrated, and good coverage of the s.RGB color space, but professionals in media creation fields will find the Adobe RGB coverage too limiting.
The Acer G257HU Smidpx does not support HDR.
The Acer G257HU Smidpx has a mediocre design. The stand cannot be removed, and unlike most monitors currently on the market, it cannot be VESA mounted. The stand is extremely basic, and has bad ergonomics. It has a narrow tilt range but cannot swivel and there is no height adjustment.
The stand supports the monitor well, but it has a large footprint and cannot be removed. The stand creaks when moved or adjusted and does not seem well built.
Bad ergonomics. There is no height adjustment, and it doesn't swivel. There is a very limited tilt range.
Very plain back. The Acer G257HU Smidpx cannot be VESA mounted, and there is no cable management.
There is no gap between the bezel and the screen. The borders are not distractedly large, but they aren't thin either.
The monitor looks good from the side. The stand prohibits the monitor from being placed too close to the wall.
Mediocre build quality. While there are no major issues with the build, there is nothing that stands out either.
The Acer G257HU does not have local dimming. The above video is for reference only.
Very good peak brightness in SDR, very similar to the ASUS VG248QE. There is very little variation in brightness across window sizes.
HDR is not supported.
Very good horizontal viewing angles. The image doesn't degrade when viewed at an angle, which is good for sharing your work with a colleague, and the edges don't fade when sitting close to the screen either.
Mediocre vertical viewing angles, which can be a problem as the stand has very little adjustments, so it is harder to be in an optimal vertical viewing position.
Excellent gray uniformity. There are some brighter spots in the center but these shouldn't be too distracting.
Disappointing color accuracy out of the box. The most accurate picture mode is 'User -> User'. The gamma curve does not follow our target at all, and most scenes are significantly darker than they should be. White balance is significantly higher than our threshold of 3 and it is noticeable to most people even when browsing the web. Colors are just as bad.
After calibration, the Acer G257HU has excellent accuracy. Color and White Balance dEs are much closer to the target, and most people won't be able to tell the difference. The gamma curve is almost perfectly corrected.
We chose the 'User' picture mode, as it provides the most control over the settings.

Excellent coverage of the s.RGB color gamut, which is great for daily usage, but professional users in the print and publishing industries will be disappointed by the limited Adobe RGB coverage. The 'Graphics' picture mode did not improve the color gamut coverage.

Excellent color volume. Most of the gaps in the color volume are due to the gaps in the color space. The limited contrast ratio limits the Acer G257HU's ability to produce deep, dark colors.
HDR gamuts are not supported.
HDR color volumes are not supported.
The Acer G257HU Smidpx shows signs of image retention, even after a 10 minute cooldown from our test clip.
The Acer G257HU Smidpx has one of the worst gradient performance that we have measured. There is 8 bit banding in all colors.
Perfect color control, there is no bleed between pixels.
Good reflection handling, similar to most monitors we have tested. The screen remains clear with a decent amount of ambient light but can't overcome strong glare in a bright room.
The Acer G257HU has a great fast response time, slightly better than the Dell P2417H. The best setting is with OD 'Off', as 'Normal' and 'Extreme' introduce a lot of overshoot but don't help the response time. With the 'off' setting there is no overshoot in any of the transitions.
The Acer G257HU Smidpx is flicker-free and uses DC dimming to dim the backlight, so there are no duplications in moving objects. It can't introduce flicker to reduce motion blur.
The Acer G257HU does not support a variable refresh rate.
Excellent low input lag, one of the lowest of any 60Hz monitor we have tested. It is consistent across any input resolution, great for gaming at a lower resolution.
The QHD resolution is great for this size of screen. The resolution is high enough that individual pixels aren't noticeable.
There is a headphone out port with adjustable volume. This is decent for connecting speakers or headphones to your monitor, but the DAC might cause some loss in sound quality compared to if you connected your speakers directly to your computer.
This monitor has a limited set of features. There are internal speakers, and a 3.5mm output to connect external speakers or headphones. It doesn't support HDR and has no USB charging ports.
Changing some of the settings causes the brightness to reset back to the maximum setting.
The controls are not very intuitive, and the buttons themselves are quite small so it can get some getting used to.
We tested the Acer G257HU Smidpx, which is a 25" 1440p monitor.
If someone comes across a different type of panel or if their monitor doesn't correspond to our review, let us know and we will update the review. Note that some tests such as the gray uniformity may vary between individual units.
