Panel26.5-inch OLED, 4th-generation Primary RGB Tandem; 2560 × 1440 (QHD), 0.2292 mm pixel pitch

In a tandem structure light comes from more than one OLED layer; LG associates this with higher brightness and lifetime.

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.

BrightnessTypical 335 cd/m², minimum 300 cd/m²; up to 1500 nits peak according to LG

The peak value applies to a small part of the screen in HDR content; brightness on a full white screen is much lower.

Variable refreshAMD FreeSync Premium Pro, NVIDIA G-SYNC Compatible, VESA AdaptiveSync LGVESA 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
Connections2 × HDMI 2.1, 1 × DisplayPort 1.4 (DSC), USB 3.0 (1 upstream, 2 downstream), 4-pole headphone out

QHD at 280 Hz is reached over DisplayPort 1.4 using DSC compression. There are no built-in speakers.

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
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.
