Release year20252024
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		31.5-inch OLED, 16:9; 3840 × 2160; 0.1814 mm pixel pitch; matte AGLR surface

About 140 ppi keeps text sharp at 32 inches; the matte surface diffuses reflections but can make blacks look slightly greyer than a glossy finish.

LG
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		0.03 ms GtG

GtG is the time a pixel takes to move from one grey shade to another; it is not the same as total input lag.

LG
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.

HDRHDR10; VESA DisplayHDR 400 True Black 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.

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		NVIDIA G-SYNC Compatible; AMD FreeSync Premium Pro; VESA AdaptiveSync and ClearMR certifications LG
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.

Refresh and Dual Mode—240 Hz at 4K; Dual Mode switches to FHD (1920 × 1080) at 480 Hz via hotkey or joystick

Dual Mode doubles the refresh rate by lowering the resolution; it improves motion clarity in competitive games, while 1080p looks softer on the desktop.

LG
Brightness and contrast—275 nits typical (250 minimum); 1,500,000:1 typical contrast LG
Colour and HDR—DCI-P3 98.5% (CIE 1976); 1.07 billion colours; HDR10; VESA DisplayHDR True Black 400

The True Black 400 certification sets black level and small-area brightness criteria for OLEDs; full-screen brightness stays below that.

LG
Connections—2 × HDMI 2.1; 1 × DisplayPort 1.4 (DSC); USB 3.0 (1 upstream, 2 downstream); 4-pole headphone out

4K 240 Hz runs over DisplayPort 1.4 with DSC compression. There is no USB-C input or KVM.
