26.5-inch 4K 240 Hz QD-OLED gaming monitor

The Acer Predator X27 uses a 26.5-inch QD-OLED panel with a 3840 x 2160 resolution and a 240 Hz refresh rate. A 0.03 ms grey-to-grey response time and AMD FreeSync Premium Pro with NVIDIA G-Sync Compatible certification keep motion clear. VESA DisplayHDR True Black 400 and 99 % DCI-P3 coverage provide high contrast and wide colour volume for competitive and immersive play.

Competitive gamers and colour-critical creators

Players who need 4K detail at 240 Hz with near-instant pixel response will benefit from the OLED panel and adaptive-sync support. Users who require sustained full-screen brightness above 250 nits typical or who prefer a non-OLED substrate for static desktop work should consider alternative panel technologies.

0.03 ms response time with 240 Hz refresh

The 0.03 ms GtG figure combined with a 240 Hz native refresh rate determines how cleanly fast motion renders without ghosting. If your GPU cannot sustain high frame rates at 3840 x 2160, the panel’s speed advantage goes unused, so match the monitor to graphics performance.
