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		33.94-inch WOLED; 3440 × 1440; 21:9; 800R curve; anti-glare (matte) surface

800R means the screen curves like an arc of a circle with an 800 mm radius. Pixel pitch is 0.231 mm.

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.

LG		240 Hz; 0.03 ms (GtG); Adaptive-Sync VRR

ASUS lists VESA AdaptiveSync Display 240Hz, AMD FreeSync Premium Pro and G-SYNC Compatible certification.

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		1300 cd/m² HDR peak brightness; HDR10; VESA DisplayHDR 400 True Black

ASUS gives this figure, asterisked, as peak HDR brightness; it is not sustained full-screen brightness.

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

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		—
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.
