Based on an AHVA (IPS) panel by AU Optronics, the ASUS TUF VG259Q monitor features wide 178° viewing angles, a 400-nit peak brightness, a static contrast ratio of 1,000:1, and dithered 8-bit color depth support (6-bit + 2-bit FRC).

The use of dithering shouldn’t concern you as most IPS panels at this price range use it for 8-bit color. There’s no noticeable difference in comparison to true 8-bit panels nor any visible artifacts such as pixel inversion.

Further, the monitor’s color gamut is 72% NTSC, which is equivalent to ~99% sRGB. The colors are accurate, consistent, and vivid.

However, out of the box calibration isn’t great (depending on the particular unit of the monitor).

For the optimal image quality, calibration is required. If you want the best image quality right away, you can use the provided sRGB picture preset for precise color reproduction.

Note, however, that you cannot adjust the monitor’s brightness while using the sRGB preset, which is a shame as for some users, the picture may be too bright in this mode.

The 1080p resolution results in a decent pixel density of roughly 90 PPI (pixels per inch) on the 24.5″ viewable screen of the ASUS VG259Q.

This means that there’s a decent amount of screen real estate available and that text and details are sharp and clear.

Some minor IPS glow, and backlight bleed is visible, as expected from an IPS panel display.

This varies between different units of the monitor, but in most cases, it’s only noticeable in dark rooms with pitch-black backgrounds on the screen, and it’s completely tolerable.
