Panel26.5-inch WOLED; 2560 × 1440 (16:9); 0.229 mm pixel pitch; anti-glare surface

WOLED is LG Display’s panel type using a white OLED layer with colour filters; each pixel makes its own light, so blacks go fully dark. Long-lasting static images raise the risk of burn-in.

ASUS		27-inch (68.5 cm) IPS; 1920 × 1080; 16:9; pixel pitch 0.3108 mm

A 0.31 mm pixel pitch works out to about 82 ppi at 27 inches. Viewing angles are 178°/178°.
