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		26.5-inch WOLED; anti-glare surface

WOLED uses a white OLED layer with colour filters; each pixel makes its own light, so blacks switch fully off.

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		—
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.

ASUS states the dimensions are estimates and may vary by region.

ASUS
Resolution—2560 × 1440, 16:9 ASUS
Refresh rate—Up to 480 Hz

480 Hz improves motion clarity in fast games; reaching it also needs the graphics card to render close to 480 frames.

ASUS
Response time—0.03 ms (GtG)

GtG is the grey-to-grey pixel transition time, not total input lag.

ASUS
Brightness and contrast—HDR peak 1,300 cd/m²; contrast 1,500,000:1 (typical)

The peak figure applies to a small part of the screen; ASUS notes that peak brightness may vary with colour pre-calibration.

ASUS
Colour—99% DCI-P3, 135% sRGB; 10-bit; ΔE < 2

A colour pre-calibration report is included in the box.

ASUS
HDR and certifications—HDR10; VESA DisplayHDR 400 True Black ASUS
Variable refresh—VESA AdaptiveSync Display 480Hz; AMD FreeSync Premium; G-SYNC Compatible

Variable refresh matches the monitor’s rate to the graphics card’s frame rate to prevent tearing.

ASUS
Video inputs—1 × DisplayPort 1.4 (DSC), 2 × HDMI 2.1 (FRL)

DSC compresses the signal in a way considered visually lossless so that 1440p 480 Hz fits within DisplayPort 1.4 bandwidth.

ASUS
Other connections—2 × USB 3.2 Gen 1 Type-A hub, headphone jack; no speakers ASUS
Stand—Tilt +20°/−5°, swivel ±30°, pivot ±90°, height 0–110 mm; 100 × 100 VESA; 1/4-inch tripod socket ASUS
Power consumption—Under 27 W in use; under 0.5 W standby, 0.3 W off ASUS
Warranty—3 years, including OLED burn-in

Burn-in is when long-static images leave a mark on an OLED panel; the OLED Care features aim to reduce it.
