The Acer VG271 is a good 27" IPS monitor, with a 1080p resolution and 144Hz refresh rate. It has excellent low input lag and outstanding motion handling, making it a great choice for gaming. It delivers decent picture quality overall, with great peak brightness, excellent gray uniformity, and wide viewing angles. Unfortunately, like the majority of IPS monitors, it doesn't look as good in a dark room. It also has a very basic stand, with bad ergonomics, so it might be difficult to place in an ideal viewing position.
The Acer Nitro VG271 has a decent design. The stand is wide, but not very large, so you can easily place objects in front of the monitor. It supports the monitor well, but wobbles quite a bit when nudged. The bezels are thin on the sides, great for a multi-monitor setup. Finally, although it's mostly made of plastic, it has decent build quality, and there shouldn't be any issues.
The stand is quite small, leaving lots of room in front of the display for small objects. Unfortunately, it wobbles quite a bit when nudged.
The stand has a great tilt range, but that's it. It can't swivel, and there is no height adjustment. There is no cable management either.
The back of the monitor is quite basic. There are vents along the 'v' shaped protrusion on the back, and a VESA mount can be attached directly to the back, without any spacers or adapters. There is a quick release on the stand, great for mobile professionals that need to move the monitor quickly.
The monitor itself is fairly thin, but the stand sticks out quite a bit, preventing the monitor from being placed flush with the back wall.
The Acer Nitro VG271 delivers decent picture quality overall. Like the majority of IPS monitors, it can't display deep blacks, but has great wide viewing angles. This monitor has great peak brightness and decent reflection handling, making it a great choice for a bright room with a lot of natural light. It supports HDR, but lacks most of the features necessary for a great HDR experience. It has great gray uniformity, with very little distracting dirty screen effect, and it has outstanding gradient performance.
The VG271 has a decent contrast ratio, but like most IPS monitors, it doesn't produce deep blacks in a dark room. It also lacks a local dimming feature, which could improve dark room performance. For better dark room performance, check out the MSI Optix G27C.
This monitor does not have a local dimming feature. The above video is for reference only.
Great peak brightness, very similar to the ASUS VG279Q. This monitor gets bright enough for any room, even if you have a lot of natural light. There is no noticeable variation in brightness with different content, which is great.
Decent peak brightness in HDR, slightly better than the Gigabyte Aorus AD27QD. Small highlights in dark scenes stand out, but in bright scenes they aren't as bright as they should be.
For HDR to work, you have to choose the 'HDR' Picture Mode, and set the HDR setting to either 'Auto', or 'HDR400'. For the purposes of our testing, we chose the 'HDR400' setting.
Like most IPS monitors, the Acer Nitro VG271 has decent horizontal viewing angles. When viewed at wider angles, the black levels remain the same, but the brightness decreases gradually, causing the contrast ratio to decrease and the image to appear washed out. At wider angles, colors lose accuracy.
Like the majority of IPS displays, the VG271 has very good vertical viewing angles. At moderate angles, colors begin to shift. When looking at the monitor from above, the black levels remain almost constant, but from below, there is a bit more of a noticeable shift in black levels. This is only at very wide angles, though, and shouldn't cause any issues for most people.
Excellent gray uniformity. The sides of the screen are slightly darker, and there is some noticeable banding near the center, which may be distracting in some cases.
With the out-of-the-box settings, the Acer Nitro VG271 has decent accuracy. The color temperature is a bit warm, and gamma is relatively flat at 2.2, but still close to the sRGB target curve. The average color error is acceptable, but some colors have noticeable inaccuracies, as do brighter grays.
After calibration, this monitor has excellent accuracy. There are no noticeable errors remaining in any color, and gamma follows the target curve almost perfectly. The color temperature is almost perfect.
You can download our ICC profile calibration here. This is provided for reference only and should not be used, as the calibration values vary per individual unit even for the same model due to manufacturing tolerances.
sRGB Picture Mode: User (calibrated)Adobe RGB Picture Mode: User
Excellent color gamut, very similar to the VG279Q. Unfortunately, coverage of the wider Adobe RGB color space might be too limited for professional photo and video editing.
sRGB Picture Mode: User Adobe RGB Picture Mode: User
Excellent SDR color volume. Like most IPS monitors, it can't display dark saturated colors very well, and like most displays, blues aren't as bright as other colors.
DCI P3 Picture Mode: HDR→ HDR400Rec. 2020 Picture Mode: HDR→HDR400
This monitor can't display a wide color gamut, which is very important for HDR content. This isn't ideal for HDR gaming or watching movies in HDR.
DCI P3 Picture Mode: HDR→ HDR400Rec. 2020 Picture Mode: HDR→HDR400
Mediocre HDR color volume. It is limited by the lack of wide color gamut, and it can't produce dark saturated colors very well.
There are no signs of temporary image retention on the VG271, even immediately after displaying our high-contrast static test image for 10 minutes.
This monitor has outstanding gradient performance, among the best we've ever seen. There is almost no noticeable banding in any shade.
Unfortunately, there are some signs of pixel errors, which is especially noticeable in the vertical columns, where each color extends above and below the block of solid color into the gray area. Although these are noticeable with our test pattern, they aren't noticeable with most regular content.
Decent reflection handling, very similar to the LG 27UD58-B. Reflections aren't diffused very much, and can be distracting in a really bright room with a lot of lights.
The VG271 has outstanding motion handling. It has an extremely fast response time, so motion looks great, with very little blur behind fast-moving objects. The backlight is also flicker-free, so motion is clear of distracting duplications. There is an optional black frame insertion feature, which helps clear up any remaining persistence blur. The monitor has a great 144Hz refresh rate, and it supports FreeSync, even with a recent NVIDIA graphics card.
The Acer VG271 has an excellent response time, but it is a bit slower than other 144Hz monitors, like the VG279Q or Acer Predator XB271HU. There is very little distracting overshoot, but transitions between dark scenes are a bit slower, which can cause more noticeable blur behind fast-moving objects.
There are three options for the response time, but there is very little difference between them. We recommend the 'Extreme' setting, as it delivers the fastest response time with almost no downsides. Unfortunately, this setting isn't available when FreeSync is enabled, resulting in a slightly slower response time. If the Over Drive setting is set to 'Extreme', when FreeSync is enabled it will automatically switch to 'Normal'.
This monitor's backlight is completely flicker-free, which is great. There is an optional Black Frame Insertion feature, which can be enabled by setting the VRB setting to either 'Normal', or 'Extreme'. The above charts were taken with the 'Extreme' setting. The 'Normal' setting, shown here, is a bit brighter, but slightly less effective at reducing persistence blur.
When connected to a source outputting 1080p, the refresh rate must be at least 120Hz for BFI to work.
This monitor has an excellent 144Hz refresh rate, great for gaming. It also supports FreeSync, for a nearly tear-free gaming experience, over both HDMI and DisplayPort.
FreeSync also works with the latest NVIDIA drivers, as long as you have a recent 10- or 20- series NVIDIA graphics card, but for NVIDIA cards it only works over DisplayPort.
Like most monitors, FreeSync does not work if VRB (Black Frame Insertion) is enabled. When FreeSync is enabled, the 'Extreme' Over Drive setting isn't available, so the response time is a bit slower.
FreeSync is not available when either HDR or VBR (black frame insertion) are enabled.
The Acer Nitro VG271 has excellent low input lag in any mode, great for competitive gaming. The 27", 1080p screen delivers a decent amount of screen real-estate for multitasking, but it might not be enough for some people.
Lowest input lag possible at the center of the screen, when the monitor is displaying an alternative resolution at its native refresh rate. The non-native resolution tested depends on the native resolution of the monitor, following this pattern unless otherwise specified in the Input Lag text:
|Native Resolution||Non-Native Resolution Tested|
The VG271 has excellent low input lag, even when gaming at 60Hz, great for console gamers. HDR doesn't add any noticeable input lag, but the VRB feature (Black Frame Insertion) is a bit higher, but still great. Both BFI modes (Extreme and Normal) have the same input lag. Non-native resolutions aren't scaled by the monitor, but this shouldn't be an issue for most people, as most graphics cards will scale the image before sending it to the display.
The 27", 1080p display provides a decent amount of screen real-estate, but some people might be disappointed by the relatively low native resolution.
This monitor has a decent selection of inputs, so you shouldn't have any issues connecting your devices. There is an audio out port with adjustable volume, suitable for connecting headphones.
The Acer VG271 supports HDR10, and it has built-in speakers, but is otherwise a fairly basic monitor. It has a few additional features, including Picture-in-Picture and Picture-by-Picture support, and it can add virtual crosshairs to any game. Unfortunately, the controls and OSD are a bit difficult to get used to. Thankfully, frequently used settings can be assigned to one of three hotkeys, and you can create custom settings for different uses.
This is a relatively basic monitor, with few additional features. It supports Picture-in-Picture and Picture-by-Picture, and can add virtual crosshairs to any game.
We tested the 27" VG271, version Pbmiipx, model UM.HV1AA.P02, which is the only size available. The VG271 is part of Acer's Nitro VG1 lineup, which has other models available. We do not expect our review to be valid for the other models.
If someone comes across a different type of panel or if their VG271 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.

The VG271 we reviewed was manufactured in December 2018.
The Acer VG271 is a good gaming monitor, but is a bit worse overall than most comparable models. See our recommendations for the best monitors, the best 27 inch gaming monitors, and the best budget monitors.
The ASUS VG279Q is better than the Acer VG271. The ASUS has a much better stand, with a full range of ergonomic adjustments, and it has slightly better black uniformity, but this varies between units. Unlike the VG271, the VG279Q doesn't support HDR, but this doesn't add much on the Acer anyway.
The Acer Predator XB271HU is slightly better than the Acer VG271 for most uses, and is much better for gaming. The XB271HU has a much better stand, offering a full range of ergonomic adjustments, and it has better motion handling, with a slightly faster response time. The XB271HU also has a higher resolution screen, so you can see more fine details in your favorite games.
Although they use different panel types, the Acer VG271 is a bit better than the ViewSonic XG2402. The VG271 has an IPS panel, which has much better viewing angles. The Acer also supports HDR, and has better gray uniformity. The ViewSonic, on the other hand, has a much better stand and a faster response time, although, unlike the Acer, the XG2402 doesn't have an optional black frame insertion feature.
Although they use different panel technologies, the Acer VG271 is much better than the MSI Optix G27C. The Acer uses an IPS panel, and has much wider viewing angles, better gradients, and better motion handling. The Acer also supports HDR, and has an optional black frame insertion feature. The MSI, on the other hand, has better reflection handling.
