The ASUS TUF Gaming VG27AQL1A is a 27-inch, 1440p gaming monitor with a native 144Hz refresh rate that you can overclock to 170Hz. It's a newer model than the popular ASUS TUF VG27AQ, featuring similar specs, including FreeSync VRR and G-SYNC compatibility. It also has an ELMB Sync feature to reduce persistence blur. It has features many other gaming monitors have, like Shadow Bost and virtual crosshairs, but it's rather limited in extra perks besides that. It has an ergonomic stand and two USB 3.0 ports to which you can connect your devices.
Our Verdict
The ASUS VG27AQL1A is okay for PC gaming. It has a 170Hz overclockable refresh rate, FreeSync support, G-SYNC compatibility, and incredibly low input lag. However, motion is blurry with a slow response time at any refresh rate. On top of that, its low contrast and disappointing black uniformity mean it's not the best choice for dark-room gaming, and it has a terrible local dimming feature.

Popular Monitor Comparisons
The ASUS VG27AQL1A is a basic entry-level 1440p gaming monitor that has a slow response time, and it's a downgrade from the monitor it replaced, the ASUS TUF VG27AQ. There are other 1440p gaming monitors you can get in a similar price with better performance, like the LG 27GP850-B/27GP83B-B and the Dell G2724D.
Also, make sure to check out our recommendations for the best gaming monitors, the best 144Hz monitors, and the best 1440p monitors.
The ASUS TUF Gaming VG27AQL1A and the ASUS TUF VG27AQ perform very similarly. The VG27AQL1A has a slightly higher max refresh rate, it gets much brighter in HDR, displays a wide color gamut, and has a quicker response time at 60Hz. However, the VG27AQ has better ergonomics, better out-of-the-box accuracy, and its BFI feature works over a wider frequency range.
The ASUS TUF Gaming VG27AQL1A and the Samsung Odyssey G50A S27AG50 are similar gaming monitors. They each have an IPS panel with a 1440p resolution. The Samsung has much better motion handling because it has a quicker response time at its max refresh rate and 60Hz, and it gets brighter, so it does a better job at fighting glare. The ASUS has built-in speakers and a local dimming feature, both of which the Samsung doesn't have, but the local dimming doesn't add much because it performs terribly.
The ASUS TUF Gaming VG27AQL1A is better than the ASUS TUF Gaming VG27WQ1B, but they have different panel types. The VG27AQL1A has an IPS panel with wider viewing angles. It also has much better ergonomics, a quicker response time, and gets brighter in HDR. However, the VG27WQ1B has a VA panel with a better contrast, it displays clearer text, and it has much better out-of-the-box accuracy.
The ASUS TUF Gaming VG27AQL1A and the Gigabyte M27Q (rev. 1.0) are very similar 1440p gaming monitors with a 170Hz refresh rate. Gaming-wise, the Gigabyte performs better because it has a faster response time, at max refresh rate and 60Hz. It also has wider viewing angles, gets brighter to combat glare, and offers more features like USB-C input, a Picture-in-Picture mode, and an integrated KVM.
We buy and test more than 30 monitors each year, with units that we buy completely on our own, without any cherry-picked units or samples. We put a lot into each unbiased, straight-to-the-point review, and there's a whole process from purchasing to publishing, involving multiple teams and people. We do more than just use the monitor for a week; we use specialized and custom tools to measure various aspects with objective data-based results. We also consider multiple factors before making any recommendations, including the monitor's cost, its performance against the competition, and whether or not it's easy to find.
Test Results
The ergonomics are fantastic, so you won't have any trouble placing it in an ideal viewing position. The back of the monitor has some etched designs, giving it a gamer-friendly aesthetic. There's also a small cutout in the stand for cable management.
The V-shaped stand has a wide footprint, but you can easily place things in front of it, like a keyboard or mouse. It supports the monitor well, and there's no wobble.
This monitor has a low contrast ratio, and the local dimming only slightly improves it. Blacks appear gray next to bright highlights in dark rooms. If you prefer something similar with a VA panel and better contrast, then check out the ASUS TUF Gaming VG27WQ1B.
This monitor has a terrible edge-lit local dimming feature. There are four dimming zones that only slightly improve contrast. Zone transitions are slow and visible, and the local dimming doesn't improve the picture quality in HDR. The setting to control it is called Dynamic Dimming, and it automatically turns on in HDR.
The SDR brightness is good. It gets bright enough to combat glare, and it remains mostly consistent with different content. Sadly, its minimum brightness is bright, which isn't ideal if you like to work in a dark room and you're sensitive to bright lights. These measurements are from after calibration in the 'Racing' Picture Mode.
The HDR brightness is decent, but small highlights don't pop against the rest of the image. The EOTF doesn't follow the target PQ curve well, as most scenes are too bright until there's a sharp roll-off at its peak brightness, so it keeps details before your source does any tone mapping. The results are with the 'HDR Gaming' Picture Mode.
The black uniformity is disappointing. There's significant clouding throughout, and backlight bleed near the top and bottom right corners. The uniformity is worse with local dimming enabled because there's more blooming around bright objects on dark backgrounds.
This monitor has mediocre accuracy before calibration. It has an sRGB mode, but it doesn't clamp colors to the sRGB color space, so they're oversaturated. Most colors are slightly inaccurate, but the white balance and color temperature are both good. Gamma follows the target sRGB curve well, but some dark scenes are too dark. The sRGB mode locks most picture settings, and even changing the Picture Mode to 'Racing' doesn't improve accuracy, as you can see here.
The accuracy is outstanding after calibration. All white balance and color inaccuracies are corrected, and the colors aren't oversaturated anymore. The color temperature is extremely close to the 6500K target, and gamma is similar to before calibration, but some dark scenes are a bit too bright now.
The ASUS TUF VG27AQL1A has a fantastic SDR color gamut. It has perfect coverage of the sRGB color space used in most web content, and great coverage of the Adobe RGB color space used in photo editing.
The HDR color gamut is good. It has good coverage of the commonly-used DCI-P3 color space, but its coverage of the wider Rec. 2020 is a bit limited, and there are tone mapping issues with each.
The horizontal viewing angle is great. The image remains consistent when viewed from the side.
The direct reflection handling isn't bad. The matte coating absorbs light well and spreads it out, but it still has some mirror-like reflections.
This monitor keeps its black level consistent in a bright room, but because of its low native contrast ratio, they still look gray.
The monitor has an overclock feature, but due to bandwidth limitations, you can only use it with an 8-signal signal over DisplayPort.

The ASUS VG27AQL1A has mediocre motion handling across its VRR range. All the overdrive settings performly inconsistently as the frame rate drops, as even the recommend overdrive of '60' has inverse ghosting. There's also noticeable blur and some smearing with fast-moving objects.
The refresh rate compliance is disappointing. Even at low refresh rates, the monitor's response time isn't fast enough to make full color transitions before it draws the next frame, leading to blurry motion.

The CAD at 120Hz is okay, but there's noticeable blur, and even some inverse ghosting. Unlike at the max refresh rate, the recommended overdrive setting is '60' because '80' has more inverse ghosting, which means you may have to change the setting if you switch games or sources.

The CAD at 60Hz is disappointing. There's visible blur with the recommended overdrive setting of '20', and the higher settings have too much inverse ghosting.

This monitor has a backlight strobing feature, commonly known as black frame insertion (BFI). With VRR disabled, it only works between 120Hz to 170Hz. Unlike most monitors, the feature works with VRR enabled, and it works as low as 80Hz with VRR on, but it turns off if the frame rate drops below 80 fps, and it only becomes active again when the frame rate reaches 90 fps again. This means it's better to disable it if the frame rate of your game regularly drops below 80 fps, as the feature turns off anyways and the screen brightness also changes with it going on and off.
This monitor has an extremely low input lag for a responsive feel.
The monitor supports most signals from the Xbox Series X.|S Even though it's a 1440p monitor it still accepts 4k signals and downscales them, which is useful because the console only supports HDR with 4k signals.
You can use two of the USB-A ports for data transfer with USB 3.2 speeds, while the other one is only for service updates.
This monitor works well with macOS, but there are issues with VRR. There's a lot of flickering, especially in low-frame-rate games, and the screen goes black at times. It's best to not use the VRR feature with a Mac, as it works well without it. HDR works well and there aren't problems waking up from sleep, except some windows get sent back to the Mac display.
This monitor has a few additional features, some of which are listed below:
- Timer: Adds a timer on your screen.
- Crosshair: Overlays a virtual crosshair for FPS games.
- Displays: Adds a grid to help align a secondary monitor.
