The ASUS TUF Gaming VG258QM is a good overall monitor that delivers excellent performance. It's a 1080p TN monitor with a high 280Hz refresh rate, fast response time, and low input lag for smooth and responsive gaming. Unfortunately, the response time and input lag are worse at 60Hz. On the upside, it's well-suited to bright rooms due to its high peak brightness and great reflection handling. It also has an amazing SDR color gamut, but it doesn't perform well in HDR because it can't display a wide color gamut and doesn't get bright enough to bring out highlights. Viewing angles are also poor, resulting in image washout when viewing off-center, but it has fantastic ergonomics, so you can easily adjust the viewing position to suit your needs.

Our Verdict

7.7 Mixed Usage

The ASUS VG258QM is a good monitor for mixed usage. It performs best in bright lighting conditions thanks to its high peak brightness and great reflection handling. It's not as well-suited to watching movies or gaming in the dark because of its low contrast ratio. The high refresh rate, fast response time, and low input lag are excellent for gaming; however, response time and input lag perform worse at 60Hz. Unfortunately, it struggles with HDR, because it can't display a wide HDR color gamut and doesn't get bright enough to bring out highlights.

Pros
  • Exceptionally high refresh rate.
  • Low input lag.
  • Great reflection handling.
  • Fantastic ergonomics.
Cons
  • Mediocre contrast ratio.
  • Poor viewing angles.
  • Smaller size is not ideal for multitasking.
7.4 Office

The ASUS VG258QM is decent for office use. It has fantastic ergonomics, allowing you to make adjustments to your ideal viewing position. It also gets very bright and has great reflection handling, so glare shouldn't be an issue in well-lit rooms. That said, its smaller size is less suited for multitasking, and it only has a 1080p resolution. It also has poor viewing angles, making it difficult to share content.

Pros
  • Great reflection handling.
  • Fantastic ergonomics.
Cons
  • Poor viewing angles.
  • Smaller size is not ideal for multitasking.
8.5 Gaming

The ASUS VG258QM is an excellent gaming monitor. It has an extremely quick response time at its max refresh rate, which is very high at 280Hz, resulting in exceptionally smooth motion. It also has a low input lag and supports VRR to reduce screen tearing. Unfortunately, the response time and input lag are much worse at 60Hz. Also, the 1080p resolution may not be high enough for some people.

Pros
  • Fast response time at max refresh rate.
  • Low input lag.
  • Compatible with FreeSync and G-SYNC.
Cons
  • Mediocre contrast ratio.
  • Response time and input lag are significantly worse at 60Hz.
7.4 Multimedia

The ASUS VG258QM is decent for multimedia. It has great reflection handling, so glare shouldn't be an issue, and its ergonomics are superb, so you can set it to your ideal viewing position. However, the 1080p resolution may be too low if you prefer to watch movies in 4k, and the smaller screen size and poor viewing angles aren't well-suited to watching with another person.

Pros
  • Great reflection handling.
  • Fantastic ergonomics.
  • Excellent SDR color gamut.
Cons
  • Mediocre contrast ratio.
  • Poor viewing angles.
  • Small size is not ideal for watching movies and other media.
7.6 Media Creation

The ASUS VG258QM is good for media creation. It has an excellent SDR color gamut with good coverage of the Adobe RGB color space used in photo editing. It's easily adjusted to your ideal viewing position and has great reflection handling to cut glare. That said, the poor viewing angles cause the image to lose accuracy as soon as you move off-center, and the 1080p resolution may not be high enough for some content creators.

Pros
  • Exceptionally high refresh rate.
  • Great reflection handling.
  • Fantastic ergonomics.
  • Excellent SDR color gamut.
Cons
  • Mediocre contrast ratio.
  • Poor viewing angles.
  • Smaller size is not ideal for multitasking.
6.9 HDR Gaming

The ASUS VG258QM is okay for HDR gaming, mostly due to its excellent gaming performance. The high refresh rate and fast response time result in clear motion in fast-moving games. However, it's not recommended for HDR gaming because of its poor HDR color gamut and low contrast ratio.

Pros
  • Fast response time at max refresh rate.
  • Low input lag.
  • Compatible with FreeSync and G-SYNC.
Cons
  • Poor HDR color gamut.
  • Mediocre contrast ratio.
  • Response time and input lag are significantly worse at 60Hz.
  • Not bright enough to make HDR highlights pop.

The ASUS VG258QM has great SDR peak brightness. It's above the advertised 400 nits and stays consistent with different content. It should be enough to overcome glare in most lighting conditions.

We measured peak brightness after calibration using the 'Racing' Picture Mode with Brightness set to max.

The HDR peak brightness is okay. As with SDR brightness, it stays consistent when displaying different scenes, and it meets the advertised DisplayHDR 400 specification. It delivers a fair HDR experience, especially when viewing in the dark, although it may not be enough to make the brightest highlights pop as they should.

We measured the HDR brightness using the 'ASUS Gaming HDR' Picture Mode, in which the brightness setting is locked.

The ASUS VG258QM has mediocre horizontal viewing angles, but this is expected of a TN panel. The image loses accuracy as soon as you move off-center, which isn't ideal for co-op gaming. For a monitor with wide viewing angles, check out the LG 27GN800-B.

The ASUS VG258QM has decent gray uniformity, but this can vary between individual units. The upper section of the screen looks noticeably darker than the bottom, which is normal for TN panels. Thankfully, there isn't much dirty screen effect and uniformity is better in near-dark scenes.

The ASUS VG258QM has passable out-of-the-box color accuracy, though this can vary between units. There's an 'sRGB' Picture Mode, but it looks even worse, so we recommend the 'Racing' mode. Most colors are very off the mark, and while white balance is fairly accurate, there are still a lot of inaccuracies. Gamma doesn't follow the curve at all, so most scenes appear much brighter than they should, and the color temperature is colder than our target, resulting in a blue-tinted image.

After calibration, accuracy is fantastic. Any remaining inaccuracies with color and white balance shouldn't be noticeable without a colorimeter. Gamma is much improved, following the curve almost perfectly, except that very dark and very bright scenes may still be a tad over-brightened. The color temperature is almost exactly at our 6500K target.

The ASUS VG258QM can't display a wide color gamut for HDR content. Its effective coverage of the common DCI P3 color space is worse than its coverage of the wider Rec. 2020. Given its Rec. 2020 coverage, it should be capable of showing approximately 70 percent of the DCI P3 color space, but the tone mapping is wildly inaccurate, so the effective color gamut ends up being much smaller. This means that if you're trying to play content that's sending a DCI P3 signal, the monitor has trouble interpreting the color signal correctly, resulting in an image that looks far from accurate. The mapping is a little better for Rec. 2020, but if you're playing a game in HDR that's sending a Rec. 2020 signal, it will still look pretty bad.

At 60Hz, the ASUS VG258QM's response time is significantly worse than at its max refresh rate. It has a strange issue where it can't hit the target brightness within one refresh cycle, so the pixels stabilize too early, and then finally hit the target after two refreshes. It's especially apparent in the 0-40, 0-60, 0-80, and 0-100 transitions. For instance, you can see this happening here in the 0-60 transition, where it doesn't hit the target threshold within one refresh (about 16ms). Practically speaking, this results in noticeable smearing and duplications, as you can see behind our logo in the photo above.

The ASUS VG258QM has an optional Black Frame Insertion (BFI) feature, also known as backlight strobing, which can help reduce motion blur. On ASUS monitors, the BFI feature is called Extreme Low Motion Blur (ELMB), and it has five different 'Clarity' levels, which adjust the duration of the backlight strobing. Higher clarity levels hold black frames for longer, resulting in a darker image overall, meaning there's a trade-off between clarity and brightness. This monitor also lets you choose the 'Clarity Position', which changes whether the top, middle, or bottom part of the screen has more clarity by shifting the timing of the flicker pattern. Our photo and graph above are from 'Clarity' level 5, but you should adjust the BFI settings to whatever looks best to you. Note that our BFI score is based on the minimum and maximum frequency at which it operates, not the BFI's performance.
