Release year20252024
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		33.9-inch (86.2 cm) OLED; 21:9; 800R curve

800R means the screen follows the arc of an 800 mm radius circle, bringing the edges of the wide screen closer to your eyes.

LG
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		—
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		HDR10; VESA DisplayHDR True Black 400 LG
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		—
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		2 × HDMI 2.1; 1 × DisplayPort 1.4 (DSC)

DSC compresses the image in a visually lossless way to carry high resolution and refresh rates over one cable. Inputs are detected automatically.

LG
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.

ASUS		—
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.
