ASUS TUF Gaming VG259QMRL5A 24.5-inch 310Hz Monitor: specs explained

The ASUS TUF Gaming VG259QMRL5A is a 24.5-inch Full HD monitor built around speed. It uses a Fast IPS panel that ASUS says can be overclocked to a 310Hz refresh rate, and it is aimed at fast competitive games where smooth motion and quick response matter more than resolution.

Full HD at 24.5 inches

At 1920 x 1080 on a 24.5-inch screen, pixels are small enough for a sharp image at normal desk distance. This size is also a long-standing favourite for competitive play, because the whole screen can be taken in without moving your head, and it is easy on the graphics card, which helps reach very high frame rates.

What 310Hz means in practice

A 310Hz refresh rate means the image can update 310 times a second. The benefit only appears if your PC can output frames that fast, which usually means a capable graphics card and processor and a game that runs lightly. ASUS describes 310Hz as an overclock, which typically means it is switched on in the monitor's menu or driver settings and may need a DisplayPort connection.

Fast IPS and 0.3ms

IPS panels are known for good viewing angles and consistent colour. ASUS says its Fast IPS technology gives a 0.3ms (GTG, minimum) response time, which is the time a pixel takes to change from one shade to another. Such figures are measured under best-case conditions, so real-world values vary with the setting.

Colour and brightness

The listing gives 99% sRGB coverage and DisplayHDR400. sRGB is the standard colour space for most web and game content, so high coverage means colours should look as intended. DisplayHDR400 is the entry tier of the VESA HDR certification, and typically gives a modest lift over a standard screen.

Adaptive sync and motion

The monitor supports FreeSync Premium and is G-Sync compatible, so the refresh rate follows the game's frame rate to avoid tearing. ELMB SYNC lets ASUS Extreme Low Motion Blur run together with variable refresh rate, which ASUS says reduces ghosting and tearing.

Software and the stand

DisplayWidget Center lets you change on-screen display settings with a mouse instead of the buttons. The listing also mentions TUF Gaming AI features and a height-adjustable stand. A 3-year warranty is listed. The unit measures about 22.0 x 8.2 x 20.8 in and weighs 10.8 lb.

Who it suits

It suits players of fast shooters and similar competitive games who have a PC able to feed a high refresh rate. If you want a larger or higher-resolution screen, a different size class will serve better.

What to check before you buy

• PC power: check that your graphics card can approach very high frame rates in your games.
• Cable and port: use the supplied DisplayPort cable for the highest refresh rate.
• Desk space: check width, depth and height with the stand.
• Mounting: if you use a monitor arm, confirm the mounting pattern in the manual.
• Console use: check what your console outputs, as it may not reach 310Hz.
