ASUS
Audio / cameraNo built-in speakers or webcam Dell—
Panel—26.5-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
Resolution and refresh—3840 × 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 time—0.03 ms (GtG)

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

ASUS
Brightness—1000 cd/m² HDR peak

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

ASUS
Contrast—1,500,000:1 (typical) ASUS
Colour—99% 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
HDR—HDR10; VESA DisplayHDR 400 True Black ASUS
Inputs—1 × 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
USB hub and audio—3 × USB 3.2 Gen 1 Type-A; headphone jack ASUS
Variable refresh—FreeSync 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
Features—ASUS 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.
