The Acer G257HU 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.
The Acer G257HU 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.
Very plain back. The Acer G257HU cannot be VESA mounted, and there is no cable management.
The Acer G257HU delivers mediocre picture quality. It has a decent contrast ratio, great peak brightness, and good horizontal viewing angles. Colors are accurately reproduced once calibrated and it has excellent coverage of the smaller s.RGB color space, but limited coverage of the wider Adobe RGB color space, which is disappointing for professional users in the print and marketing industries. Unfortunately, it has bad black uniformity and doesn't support HDR, nor does it have a local dimming feature. It also shows signs of temporary image retention, even 10 minutes after our test clip ended.
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.
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 G7 Series 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.

sRGB Picture Mode: User (calibrated)
Adobe RGB Picture Mode: User (calibrated)
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.
The Acer G257HU has decent motion handling. It has a great response time, so motion is clear without much blur. The backlight is flicker-free, which is great, but it doesn't have any option to introduce flicker to further clear up motion. The standard 60Hz refresh rate is fine for most uses but gamers might find it too low and it doesn't support FreeSync or G-SYNC.
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 G7 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 G257HU has excellent low input lag, about as good as it can get for a 60 Hz monitor. The native 1440p resolution is great for most uses, given the size of the screen. It has a good selection of input types, but unfortunately only 1 of each.
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.
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.
The Acer G257HU has a very limited set of features. The On-Screen Display and controls are not very intuitive and can be hard to navigate. It doesn't have any USB charging ports or additional features.
We tested the Acer G257HU, 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.

Our G257HU was manufactured in Feb. 2017.
The Acer G257HU is a decent 1440p IPS monitor, but there are better choices out there that are much cheaper. See our recommendations for the best monitors under $200, the best budget gaming monitors, and the best 1440p monitors.
The Dell U2515H is much better than the Acer G257HU. The design of the U2515H is far superior, with far more ergonomic adjustments as well as VESA mounting ports. The U2515H has much better gradient handling with less banding, and is free of distracting temporary image retention. The U2515H also has better features, including the ability to daisy chain to another monitor, as well as USB charging ports.
The Acer Predator X27 is slightly better than the LG 27UK650-W. The Acer Predator X27 supports local dimming and has better HDR performance thanks to its wider color gamut and higher HDR peak brightness. The LG 27UK650-W has slightly lower input lag and feels more responsive, and this is excellent for gaming.
The LG 24MP59G is slightly better than the Acer G257HU. Both monitors have an IPS panel with wide viewing angles. The Acer G257HU has a simple 60Hz refresh rate and no VRR support, whereas the LG 24MP59G has a better 75Hz refresh rate, and supports FreeSync VRR. The Acer has a slightly larger, 25" screen, and a much better 1440p resolution, better for multitasking or for a more immersive gaming or multimedia experience.
The ASUS VG245H is somewhat better than the Acer G257HU. The ASUS has a much better design, with a stand that can be easily adjusted to an optimal viewing position. The Acer G257HU is a bit brighter and has better wide viewing angles. The VG245H has a faster response time and produces clearer motion with less blur, and supports FreeSync VRR for gaming.
The HP 27Q is somewhat better than the Acer G257HU. The HP 27Q has a better refresh rate that leaves a smaller blur trail in fast-moving content and has more screen area as it is a 27" monitor. The Acer G257HU, on the other hand, has a better input lag which makes it more responsive to your inputs and can be great for many usages.
The ASUS VG248QE is better than the Acer G257HU. The VG248QE has a higher refresh rate that delivers a nearly instantaneous response time, and the backlight can introduce flicker to further reduce motion blur. The VG248QE has lower input lag, great for gaming. The Acer G257HU has a higher native resolution, but at this size, this doesn't have a significant impact on the overall quality.
The Acer G257HU is better than the Acer GN246HL. They both deliver similar overall picture quality, but the G257HU has wider viewing angles. The G257HU has a flicker-free backlight. The Acer GN246HL has a higher refresh rate and better response time, great for gaming.
