The ASUS TUF Gaming VG259QM is an excellent IPS monitor that delivers a smooth and responsive gaming experience. It shares many similarities with its bigger brother, the ASUS VG279QM, as it also has a 1080p resolution and a 280Hz refresh rate. It has great visibility in bright environments thanks to its impressive peak brightness, but to the contrary, it isn't as well-suited for dark rooms due to its low contrast ratio. It has exceptionally fast response time, a Black Frame Insertion feature, as well as native FreeSync support and G-SYNC compatibility. It supports HDR10; however, HDR content doesn't look significantly better than in SDR because it lacks a wide color gamut and local dimming. On the upside, it has a great build quality, wide viewing angles, and outstanding ergonomics.

Our Verdict

8.0 Mixed Usage

Overall, the ASUS TUF Gaming VG259QM is a great monitor. It provides a responsive and smooth gaming experience with its low input lag and high refresh rate. Its wide viewing angles and outstanding ergonomics make it easier to share work or content, and its impressive peak brightness makes it suitable for brightly-lit settings. Sadly, while it does support HDR, it can't display a wide color gamut and lacks local dimming.

Pros
  • Wide viewing angles.
  • Good reflection handling.
  • Outstanding ergonomics.
Cons
  • Low HDR peak brightness.
  • Low contrast ratio.
7.9 Office

The ASUS TUF Gaming VG259QM is a good monitor for office use. The screen may be too small for some, especially for multitasking; however, it keeps the pixel density high, so text and images look sharper. It gets bright enough to overcome glare, and it handles reflections well. It has outstanding ergonomics and wide viewing angles, making it easy to share your work with coworkers.

Pros
  • Wide viewing angles.
  • Good reflection handling.
  • Outstanding ergonomics.
Cons
  • Low HDR peak brightness.
  • Screen size a bit small for multitasking.
8.7 Gaming

The ASUS TUF Gaming VG259QM is an excellent gaming monitor. It has low input lag, and its motion handling is superb thanks to its fast response time, high refresh rate, and Black Frame Insertion feature. It supports FreeSync natively and is compatible with NVIDIA's G-SYNC. Unfortunately, it has a low contrast ratio that makes it less ideal for gaming in the dark, and its compact size may be too small for some.

Pros
  • High refresh rate.
  • VRR support.
  • Exceptionally fast response time.
  • Outstanding ergonomics.
Cons
  • Low HDR peak brightness.
  • Low contrast ratio.
7.8 Multimedia

The ASUS TUF Gaming VG259QM is a good monitor for media consumption. It has a decent screen size with wide viewing angles so you can share content with others, and its outstanding ergonomics allow you to adjust the screen to your optimal viewing position with ease. It has an impressive peak brightness and good reflection handling to combat glare in bright rooms, but its dark room performance isn't that great due to its low contrast ratio.

Pros
  • Wide viewing angles.
  • Outstanding ergonomics.
  • Excellent gray uniformity.
Cons
  • Low HDR peak brightness.
  • Low contrast ratio.
7.9 Media Creation

The ASUS TUF Gaming VG259QM is a good monitor for media creation. Its 24.5 inch screen provides a decent amount of space to work with, and its outstanding ergonomics allow you to position it however you like. It has near full coverage of the sRGB color space, but its coverage of Adobe RGB is much more limited. Unfortunately, it has a low contrast ratio, and it can't display a wide color gamut.

Pros
  • Wide viewing angles.
  • Outstanding ergonomics.
  • Excellent gray uniformity.
Cons
  • Low HDR peak brightness.
  • Low contrast ratio.
7.2 HDR Gaming

The ASUS TUF Gaming VG259QM is a decent monitor for gaming in HDR. It has fast response time, high refresh rate, and low input lag for a responsive gaming experience. However, its low contrast ratio, as well as the lack of a wide color gamut and local dimming, limits its HDR performance. Also, it doesn't get bright enough to make highlights pop.

Pros
  • High refresh rate.
  • VRR support.
  • Exceptionally fast response time.
  • Outstanding ergonomics.
Cons
  • Low HDR peak brightness.
  • Low contrast ratio.
  • Can't display a wide color gamut.
  • No local dimming.

The ASUS VG259QM looks almost identical to its bigger brother, the ASUS VG279QM, just in a smaller, more compact size. It has thin bezels on three sides and a slightly thicker bottom bezel. It isn't too flashy and won't look out of place in an office setting.

The HDR peak brightness is okay. The brightness is very consistent when displaying different scenes. It's bright enough to deliver an alright HDR experience in games, but not in HDR movies. It's also significantly dimmer than the ASUS VG279QM, which is expected.

We measured the HDR peak brightness before calibration, using the 'ASUS Gaming HDR' Picture Mode. The screen's brightness is locked in this picture mode.

The vertical viewing angles are okay. The top and bottom of the screen remain accurate even if you sit up close due to the smaller screen size. It's more important if you have a multi-monitor setup where it's mounted above eye level.

Before calibration, the ASUS VG259QM has decent color accuracy. It has an sRGB mode that's more accurate than the Racing Mode that we used on the ASUS VG279QM, but using it locks the screen's brightness. There are some minor inaccuracies with a few colors, and white balance is off. Gamma doesn't follow the curve all that well, making dark scenes too dark and bright scenes brighter than they should be. The color temperature is very close to our 6500K target.

Note that the pre-calibration color accuracy can vary between units.

Update 08/28/2020: There's a hidden overdrive setting of '120'. It can be accessed through the service menu, as described here. Despite the name, it's actually between the 60 and 80 settings, but we don't recommend it, as there's too much overshoot.

The ASUS VG259QM has exceptional response time when playing at its maximum refresh rate, resulting in minimal motion blur in fast-moving scenes. There are many overdrive settings available. We recommend using '60', as it provides the best performance with virtually no overshoot.

Note that we found almost no difference between the '0' and '20', or the '40' and '60' overdrive settings. We suspect that the current firmware may be causing some bugs with these settings at the maximum refresh rate. We'll retest it once a firmware update is available.

The response time at 60Hz is excellent, although not as good as its bigger brother, the ASUS VG279QM. The best overdrive setting is '40,' as there's only a small amount of overshoot in the darker transitions and when transitioning from dark to bright scenes.

The ASUS TUF Gaming VG259QM has an optional Black Frame Insertion feature to help improve motion clarity called 'ELMB,' and it can be used at the same time as variable refresh rate (VRR). The standard ELMB setting (without VRR) works between 120Hz and 280Hz, while the ELMB Sync setting (with VRR) works between 50Hz and 280Hz. That said, we found that it doesn't work at all between 50Hz and 85Hz. These results are consistent with our findings on the ASUS VG279QM.

It supports FreeSync and is compatible with NVIDIA's G-SYNC; the latter only works over a DisplayPort connection.

The ASUS VG259QM has exceptionally low input lag, even with VRR enabled. However, it rises significantly when playing at 60Hz, making it less suitable for console gaming. This higher input lag at 60Hz is also something that we noticed on the ASUS VG279QM.
