Panel26.5-inch QD-OLED, 16:9; 3840 × 2160 (4K); 0.153 mm pixel pitch

The small pixel pitch (about 166 ppi) makes text and interface edges look sharper than on 27-inch 1440p monitors.

ASUS		—
Refresh rate and VRR240 Hz; 48–240 Hz variable refresh on HDMI and DP/USB-C inputs; FreeSync Premium Pro, G-SYNC Compatible, VESA AdaptiveSync Display 240Hz

All inputs support 240 Hz at 4K; variable refresh prevents tearing and stutter as the game frame rate moves between 48 and 240.

ASUS		—
Response time0.03 ms (GtG)

Grey-to-grey transition time; because OLED pixels change much faster than LCD, motion blur depends mostly on the refresh rate.

ASUS		5 ms GtG (fast mode); 8 ms GtG

Pixel transition specification, not total input lag.

Dell
Brightness and contrast1,000 cd/m² HDR peak; 1,500,000:1 typical contrast

1,000 cd/m² is a peak reached on a small area of the screen; a full white screen stays much lower. ASUS gives no typical SDR brightness value.

ASUS		—
HDRVESA DisplayHDR 400 True Black; HDR10; Dolby Vision

The True Black tier measures OLED’s very low black level; 400 is the minimum peak brightness threshold in the certification test. Dolby Vision support lets compatible sources use scene-by-scene HDR data.

ASUS		—
Colour99% DCI-P3, 145% sRGB; 10-bit (1.07 billion colours); ΔE < 2

ΔE < 2 means factory calibration deviates from target colours by an amount most people cannot see; a calibration report is included.

ASUS		1.07 billion colours; 100% sRGB and Rec.709; 99% DCI-P3 and Display P3; factory calibration average ΔE < 1.5 Dell
Inputs1 × DisplayPort 2.1; 2 × HDMI 2.1 (FRL); 1 × USB-C (DP Alt Mode, 90 W power delivery); headphone jack

USB-C takes video over a single cable and supplies up to 90 W to a laptop. The HDMI 2.1 inputs can be used for 4K 120 Hz on consoles.

ASUS		—
USB and KVM3 × USB-A 5 Gbps (USB 3.2 Gen 1) hub; KVM switch

KVM moves the keyboard and mouse attached to the monitor between two computers when the input is switched.

ASUS		—
SpeakersNone

A headphone jack or external speakers are needed for audio.

OLED protectionASUS OLED Care; Neo Proximity Sensor

OLED Care includes burn-in prevention functions such as pixel cleaning, screen shift, logo brightness adjustment and taskbar detection. The proximity sensor dims the screen when the user leaves, reducing static image time.
