Panel26.5-inch (27-inch class) QD-OLED, 16:9, anti-reflection surface

QD-OLED pairs self-emitting pixels with a quantum-dot colour layer; each pixel switches off individually, so blacks are fully dark.

ASUS		26.5-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
Resolution and refresh3840 × 2160, 240 Hz

The 4K 240 Hz signal travels over DisplayPort 1.4 with DSC compression, or over HDMI 2.1 depending on graphics-card support.

ASUS		—
Response time0.03 ms (GtG)

This is the grey-to-grey pixel transition time, not total input lag.

ASUS		—
Brightness1000 cd/m² HDR peak

ASUS notes peak brightness may vary with colour pre-calibration; the peak is reached on a small screen area.

Contrast1,500,000:1 (typical) ASUS—
Colour99% DCI-P3, 145% sRGB; ΔE < 2; 10-bit

Factory calibration (ΔE < 2) means colours are set close enough to target that differences are hard to see.

ASUS		DCI-P3 99%; sRGB 135%; factory pre-calibration report ASUS
HDRHDR10; VESA DisplayHDR 400 True Black ASUSHDR10

Dolby Vision and HDR10+ support are not listed.

ASUS
Inputs1 × DisplayPort 1.4 (DSC); 2 × HDMI 2.1 (FRL); 1 × USB-C (DP Alt Mode, 90 W power)

The USB-C input takes video from a laptop and charges it at up to 90 W over one cable. HDMI 2.1 suits consoles at 4K 120 Hz.

ASUS		1 × DisplayPort 1.4 DSC; 2 × HDMI 2.0; headphone jack; 2 × USB 3.2 Gen 1 Type-A hub

DSC (Display Stream Compression) compresses the signal without visible loss so DisplayPort 1.4 has enough bandwidth for high refresh rates. There are no speakers and no USB-C input.

USB hub and audio3 × USB 3.2 Gen 1 Type-A; headphone jack ASUS—
Variable refreshFreeSync Premium Pro, G-SYNC Compatible; VESA AdaptiveSync Display 240 Hz

Variable refresh matches the screen's rate to the graphics card's frame rate, reducing tearing and stutter.

ASUS		VESA AdaptiveSync Display 240Hz; AMD FreeSync Premium; G-SYNC Compatible

Variable refresh matches the monitor to the graphics card’s frame rate to reduce tearing and stutter.

FeaturesASUS OLED Care, KVM switch, Extreme Low Motion Blur, Neo Proximity Sensor, flicker-free

KVM shares a keyboard and mouse connected to the monitor between two computers. The proximity sensor dims the screen when the user leaves to reduce OLED wear.
