Overview
At 310 Hz, the Asus ROG Strix XG259CMS is a 24.5-inch Full HD IPS gaming monitor that puts competitive speed ahead of resolution and built-in extras. Its 1 ms GtG response claim, FreeSync Premium and G-Sync Compatible support suit high-frame-rate play, while 400 cd/m² brightness and 110% sRGB give the panel more colour volume than a basic esports screen. The stand is unusually complete for this class, offering 120 mm height adjustment, ±90° pivot and ±45° swivel. Connectivity includes HDMI 2.0, DisplayPort 1.4 and USB-C with DisplayPort Alt Mode, although the 7.5 W output is far too low for laptop charging. There are no speakers, and DisplayHDR 400 lacks a published peak-brightness figure or local-dimming information. Buy it if 310 Hz speed and strong ergonomics are priorities; skip it if you need higher resolution, meaningful USB-C power or convincing HDR.

HDR & Brightness Reality
DisplayHDR 400 is listed, but the sheet gives only 400 cd/m² typical brightness and no separate peak figure. That leaves the actual highlight headroom unknown. The IPS panel is rated at 1,000:1 contrast and no local-dimming system is published, so dark scenes will remain limited. HDR10 compatibility may help with signal handling, but buyers should treat HDR as secondary to the monitor's 310 Hz gaming focus.

Frequently Asked Questions
01 What hardware is needed to make real use of 310 Hz on the XG259CMS? +
The GPU must render close to 310 frames per second, and the CPU also matters in competitive games. Full HD helps, but demanding titles may remain well below the ceiling.
02 Why is the 7.5 W USB-C port not a laptop-docking feature? +
It carries DisplayPort Alt Mode, so it can accept video from a compatible laptop. Its power output is far below normal laptop charging requirements.
03 How does the stand differ from many 24.5-inch esports monitors? +
It includes 120 mm height adjustment, ±45° swivel and ±90° pivot, not just tilt. That makes long-session positioning much easier.
04 What limits the DisplayHDR 400 claim here? +
The sheet does not publish a separate peak-brightness figure or local-dimming information. A 1,000:1 IPS contrast ratio also limits black depth.
05 Why choose 110% sRGB rather than a plain 100% sRGB panel? +
The wider colour volume can produce more saturated colours outside a strictly clamped sRGB mode. It does not by itself prove colour accuracy.
