Panel26.5-inch WOLED; anti-glare surface

WOLED uses a white OLED layer with colour filters; each pixel makes its own light, so blacks switch fully off.

ASUS		33.94-inch WOLED; 3440 × 1440; 21:9; 800R curve; anti-glare (matte) surface

800R means the screen curves like an arc of a circle with an 800 mm radius. Pixel pitch is 0.231 mm.
