The ASUS TUF Gaming VG34VQL1B is an excellent curved ultrawide gaming monitor. It has a 34 inch screen with a 21:9 aspect ratio, which gives you more horizontal space than a typical 16:9 display, resulting in greater immersion. Its VA panel can produce deep blacks, making it great for dark rooms, but it comes at the cost of narrow viewing angles, which isn't ideal for playing co-op games or sharing content. It delivers a pretty good HDR experience as it has a wide coverage of the DCI P3 color space, and it gets bright enough to make some highlights pop. Unfortunately, even though its response time is excellent overall, there's visible black smearing in fast-moving content, regardless of the overdrive setting. Also, inverse ghosting may be noticeable when playing at a lower refresh rate.
The ASUS TUF Gaming VG34VQL1B is a great monitor overall. It's primarily designed for gaming, but it's also well-suited for a wide variety of uses. Its 34 inch high-resolution screen delivers an immersive viewing and gaming experience and provides plenty of space for work. Gaming feels incredibly responsive, and it can deliver a pretty good HDR experience. The viewing angles are mediocre, so it isn't the best for sharing content or playing co-op games.
The ASUS TUF Gaming VG34VQL1B is good for office use. Its 34 inch screen provides plenty of space to work comfortably with multiple windows side-by-side, and it delivers sharp images and text thanks to its high pixel density. It handles reflections well and gets more than bright enough to overcome glare in well-lit environments. Unfortunately, it isn't ideal for sharing work with coworkers due to its narrow viewing angles, and it has limited ergonomic adjustments.
The ASUS TUF Gaming VG34VQL1B is an excellent gaming monitor. It has a large, high-resolution screen to provide incredible immersion, and its low input lag and high refresh rate result in amazingly responsive gameplay. Unfortunately, even though it has excellent response time, it's a bit slow in the dark transitions, causing noticeable smearing in fast-moving content. On the upside, it has a high contrast ratio that makes it well-suited for gaming in the dark.
The ASUS TUF VG34VQL1B is good for media consumption. It has a large, high-resolution screen that feels incredibly immersive. Its VA panel has a high contrast ratio, making it great for dark room viewing, but it's at the expense of narrow viewing angles, so it isn't ideal for sharing content with others.
The ASUS TUF Gaming VG34VQL1B is great for content creation. Its ultrawide format gives you tons of horizontal screen space, which is great for video editors working with a timeline. It has near-full sRGB and outstanding DCI P3 coverage, superb gradient handling, and no color bleed. Sadly, it doesn't have the best viewing angles, so you lose image accuracy when viewing from the side.
The ASUS TUF VG34VQL1B is good for gaming in HDR. It has an excellent contrast ratio, wide DCI P3 coverage, and it gets bright enough to bring out some highlights in HDR content. However, it lacks a local dimming feature. The refresh rate is limited to 144Hz when gaming in HDR, but it shouldn't be noticeable to most people.
The ASUS TUF Gaming VG34VQL1B has a fairly simple design that's nearly identical to the ASUS TUF Gaming VG27AQL1A. It has a curved screen with thin borders on three sides and a thicker bottom bezel. The stand is different from older TUF Gaming models, as the base is now V-shaped instead of a rectangle, and the column is thinner.
The V-shaped stand is quite wide, but the feet themselves are thin, so you still have a fair amount of space left in front to put other things. It feels sturdy, and the screen only wobbles a bit.
The ASUS VG34VQL1B has sub-par ergonomics. As is expected, it can't rotate to portrait mode due to its wide format. It can swivel, but the range is pretty narrow.
Except for the branding, the back is plain. There's a removable piece of plastic at the bottom of the stand's column for cable management.
The ASUS VG34VQL1B's borders are thin, great for multi-monitor setups.
Both the stand and the screen are thick, so you need a fairly deep desk to put it on.
The ASUS TUF Gaming VG34VQL1B's build quality is decent. Its all-plastic construction doesn't feel particularly premium, but there are no obvious issues with it. The back flexes a little bit where the inputs are, and the plastic piece used for cable management also feels flimsy.
The ASUS TUF Gaming VG34VQL1B has an excellent contrast ratio, which means it can display deep blacks, making it great for dark rooms. It's quite a bit higher than the advertised 4000:1 contrast; however, this can vary between individual units.
The ASUS TUF VG34VQL1B doesn't have local dimming. The video above is provided for reference only.
The ASUS TUF VG34VQL1B has great SDR peak brightness. It's very consistent across different content, but it doesn't quite reach the advertised 550 cd/m². That said, it's still more than enough to overcome glare, even in bright, sunny rooms. We managed to reach 543 cd/m² using a checkerboard pattern with Contrast set to max, but it comes at the cost of image accuracy.
We measured the SDR peak brightness after calibration in the 'User' Picture Mode, with Brightness set to max.
Decent HDR peak brightness. It's very consistent, and it's bright enough to bring out some highlights in HDR content, especially when gaming in the dark. It doesn't achieve the advertised 550 cd/m², but it does meet the DisplayHDR 400 requirement.
We measured the HDR peak brightness in the 'ASUS Gaming HDR' Picture Mode.
The ASUS TUF Gaming VG34VQL1B has mediocre horizontal viewing angles. Images lose accuracy almost as soon as you move off-center, which isn't ideal for playing co-op games or sharing content.
The vertical viewing angles are sub-par. This means that images look inaccurate if you set the monitor below or above eye level.
Gray uniformity is outstanding; however, this can vary between units. The sides are just slightly darker, and dirty screen effect is minimal in the center. Uniformity is much better in dark scenes.
Black uniformity is okay. There's visible backlight bleed along the top and bottom edges of the screen. Note that black uniformity can vary between individual units due to manufacturing tolerances.
The ASUS TUF VG34VQL1B has great accuracy out of the box. Most white balance and color inaccuracies are difficult to spot with the naked eye. The color temperature is on the warmer side, resulting in a slight red/yellow tint. Gamma doesn't follow the sRGB curve at all, making most scenes appear darker than they should. Note that accuracy varies between units.
The 'sRGB' Picture Mode is the most accurate and the one that we used for testing, but using it locks the Contrast and Brightness settings.
Accuracy is exceptional after calibration. The remaining inaccuracies aren't noticeable to the naked eye. The color temperature is much closer to our 6500K target. Gamma improved significantly, but some very dark and very bright scenes are now over-brightened.
You can download our ICC profile calibration here. This is provided for reference only and shouldn't be used, as the calibration values vary per individual unit due to manufacturing tolerances, even for the same model.
The ASUS VG34VQL1B has an outstanding SDR color gamut. It has near-full coverage of the sRGB color space used in most content. Its Adobe RGB coverage is excellent, but it might not be enough for some professional photo editors.
Exceptional SDR color volume. It only has trouble displaying bright blues, which is normal for LCDs.
The ASUS VG34VQL1B has a good HDR color gamut. Its DCI P3 coverage is outstanding, exactly matching the advertised 90%. However, its Rec. 2020 coverage is much more limited.
Decent HDR color volume. It has difficulty displaying bright, saturated colors because its HDR brightness is limited.
The ASUS TUF Gaming VG34VQL1B shows almost no signs of image retention. The small amount detected after displaying a high-contrast image disappears quickly. Note that image retention can vary between units.
Gradient handling is superb. You shouldn't see any banding in most content.
There's no color bleed on this monitor.
The ASUS VG34VQL1B has good reflection handling. Combined with the monitor's high peak brightness, you shouldn't have any visibility issues, even in well-lit environments.
The ASUS VG34VQL1B has good text clarity. Windows ClearType (top photo) makes diagonal and curved lines look better, like on the R and N. However, it also makes vertical lines thinner, like on the T and I.

The response time at 60Hz is good overall; however, dark transitions are very slow, making fast motion look blurry in some scenes. The best Variable Overdrive setting at 60Hz is '80', although it has a lot of dark overshoot, causing inverse ghosting. The '60' option is similar; it has less overshoot but slightly slower response times.
The ASUS TUF Gaming VG34VQL1B's backlight is entirely flicker-free, which helps eliminate image duplication and reduce eye strain.
The ASUS VG34VQL1B has a Black Frame Insertion feature to improve motion clarity. It's backlight strobing, to be more precise, and it's called ELMB. Unlike some ASUS monitors, it isn't usable while VRR is active, and it only works above 100Hz. Note that the BFI score is based on the minimum and maximum frequency at which it operates, not the BFI's performance.
The ASUS VG34VQL1B has a high refresh rate to deliver a smooth and responsive gaming experience. It supports FreeSync natively and is compatible with G-SYNC as well; however, the latter only works over a DisplayPort connection. The refresh rate over HDMI is limited to 100Hz at 8-bit and 60Hz at 10-bit. The refresh rate limit at 10-bit over DisplayPort is 144Hz. Some users have reported flickering when VRR is enabled, but we didn't notice any during testing.
