Asus has brought the ROG Strix XG259QNSR Ace to market as a monitor built squarely for esports. The pitch is simple: skip 4K and flashy HDR, and focus instead on refresh rate and response time. It uses a 24.5-inch Full HD panel with an overclocked refresh rate of up to 420Hz, clearly aimed at games like Counter-Strike 2 and Valorant, where milliseconds matter.
While much of the monitor market is pushing bigger screens and higher resolutions, Asus is leaning into a more traditional competitive setup. For esports titles, 1080p remains a practical standard because players typically prioritize the highest possible frame rates and the lowest possible input latency over image fidelity.
The monitor is built around a Fast IPS panel with a claimed response time of 0.3ms. Asus also includes ELMB Sync, allowing backlight strobing to work alongside adaptive sync technologies including G-Sync and FreeSync Premium. For fast-moving scenes, Variable Overdrive 2.0 adjusts pixel response as frame rates change.

Color performance is about what you would expect from a gaming IPS display. Asus lists 90% DCI-P3 and 115% sRGB coverage, along with VESA DisplayHDR 400 certification. That said, the source notes that buyers should not expect standout HDR performance from a standard edge-lit IPS panel.
Asus is also adding software features alongside the hardware. Its ROG Gaming AI package includes a dynamic crosshair that changes color depending on the background, plus Shadow Boost, which brightens dark areas without noticeably overexposing the rest of the scene. Settings can be managed through the DisplayWidget Center desktop app.
Key specs include:
- 24.5-inch display
- 1920 × 1080 resolution
- Up to 420Hz overclocked refresh rate
- Fast IPS panel with up to 0.3ms response time
- G-Sync and FreeSync Premium support
- 90% DCI-P3 and 115% sRGB color coverage
- VESA DisplayHDR 400 certification
- DisplayPort 1.4 and HDMI
Pricing and availability
Asus has not yet disclosed the price or a release date. The monitor will be available in black, with a white version offered as an option.
As the gaming display market keeps chasing higher refresh rates, the XG259QNSR Ace stands out as a highly specialized tool for players who value raw speed over versatility.
