Release year20252024
Panel44.5-inch WOLED, 21:9, 800R curve; 5120 × 2160 (5K2K), 0.2035 mm pixel pitch (about 125 ppi); MLA+

800R means the screen curves along a circle with an 80 cm radius, so the edges sit closer to the eyes. MLA+ (micro lens array) directs OLED pixel light forward to raise brightness.

LG		31.5-inch QD-OLED; 3840 × 2160 (16:9); 240 Hz; 0.03 ms (GtG); 10-bit; 0.182 mm pixel pitch; anti-reflection surface

In QD-OLED, blue OLED light is converted to red and green by quantum dots, keeping colours saturated. The semi-glossy surface can make blacks look grey in a bright room.

ASUS
Refresh rate and response165 Hz at 5K2K; 330 Hz at WFHD with VESA-certified Dual-Mode; 0.03 ms (GtG)

Dual-Mode doubles the refresh rate by lowering the resolution: 330 Hz for fast competitive games, 5K2K at 165 Hz for detailed games.

Brightness and HDR275 cd/m² typical (minimum 250); HDR10, VESA DisplayHDR True Black 400; DCI-P3 98.5%; 10-bit; contrast 1,500,000:1 (typical)

DisplayHDR True Black 400 is VESA’s certification for screens that can turn black fully off, such as OLED, and requires 400 nits peak brightness.

LG		—
SyncNVIDIA G-SYNC Compatible, AMD FreeSync Premium Pro, VRR

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

LG		Adaptive-Sync; FreeSync Premium Pro; G-SYNC Compatible; ELMB

ELMB is a mode that inserts black between frames to reduce motion blur.

ASUS
Inputs2 × HDMI, 1 × DisplayPort 2.1 (DSC), 1 × USB-C (5120 × 2160 at 165 Hz, data, 90 W power); 2 × USB 3.0 downstream; 4-pole headphone/mic

DSC compresses the image visually losslessly so high resolution and refresh rate fit through one cable. USB-C gives a laptop video, data and 90 W charging over one cable. LG notes NVIDIA released a driver in April 2025 that fixed screen blackouts seen over DisplayPort.

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

4K 240 Hz 10-bit over DisplayPort 1.4 uses Display Stream Compression (DSC). The 90 W USB-C port can drive and charge a laptop over a single cable.

ASUS
PiP and PbPPIP and 2-source PBP

PiP shows one source in a small window, and PbP splits the screen to show two sources side by side, for example a computer and a game console at once.

Brightness and contrast—HDR peak 1000 cd/m²; contrast 1,500,000:1

1000 cd/m² is a peak reached on a small part of the screen; full-screen white is much dimmer. ASUS notes the value can vary due to pre-calibration.

The proximity sensor dims the screen when the user leaves the desk to reduce burn-in risk; some owners wrote that they turned it off.
