Panel26.5-inch WOLED; 2560 × 1440 (16:9); 0.229 mm pixel pitch; anti-glare surface

WOLED is LG Display’s panel type using a white OLED layer with colour filters; each pixel makes its own light, so blacks go fully dark. Long-lasting static images raise the risk of burn-in.

ASUS		26.5-inch (67.32 cm) OLED, 2560 × 1440 (16:9); 0.2292 mm pixel pitch; 1.07 billion colours

Because self-lit OLED pixels can switch fully off, blacks are true black; LG gives typical contrast as 1,500,000:1. 1.07 billion colours corresponds to 10-bit colour depth.

LG
Refresh rate and response240 Hz (DisplayPort); 120 Hz over HDMI; 0.03 ms (GtG)

240 Hz is only available through the DisplayPort input; ASUS’s signal table limits the HDMI inputs to 120 Hz. For PC games above 120 Hz, use a DisplayPort cable.

Brightness and contrastHDR peak 1,000 cd/m²; contrast 1,500,000:1; 10-bit (1.07 billion colours)

Peak brightness applies to a small part of the screen; with a full white screen brightness drops noticeably. ASUS notes peak brightness may vary with colour pre-calibration.

Dolby Vision and HDR10+ support are not listed.

ASUS		—
Variable refreshVESA AdaptiveSync Display 240Hz; AMD FreeSync Premium; G-SYNC Compatible

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

ASUS		—
Inputs1 × DisplayPort 1.4 DSC; 2 × HDMI 2.0; headphone jack; 2 × USB 3.2 Gen 1 Type-A hub

DSC (Display Stream Compression) compresses the signal without visible loss so DisplayPort 1.4 has enough bandwidth for high refresh rates. There are no speakers and no USB-C input.

OLED care and warrantyASUS OLED Care; 2-year warranty (including panel burn-in)

The warranty also covers panel burn-in; terms may vary by region.

Refresh rate and response time—240 Hz; 0.03 ms (GtG)

240 Hz shows 240 frames per second, making motion smoother and less blurred in fast games; this needs a graphics card producing 240 fps and a DisplayPort or HDMI 2.1 connection. GtG is the time a pixel takes to change from one grey level to another.

LG
Brightness—Typical 200 cd/m², minimum 160 cd/m²

These are full-screen SDR figures; small HDR highlights can be brighter. LG does not give a peak HDR figure in the spec table.

LG
Colour and HDR—98.5% DCI-P3 (typical), 90% (minimum); HDR10; factory calibrated; hardware calibration ready

Hardware calibration uses LG Calibration Studio and a compatible colorimeter to adjust the monitor’s own colour tables. No VESA DisplayHDR certification is listed.

LG
Adaptive sync and gaming—NVIDIA G-SYNC Compatible, AMD FreeSync Premium, VRR; Black Stabiliser, Dynamic Action Sync, crosshair, FPS counter

Adaptive sync matches the monitor’s refresh to the graphics card’s frame rate to reduce tearing and stutter. Dynamic Action Sync is meant to reduce input lag.

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

DSC (Display Stream Compression) uses visually lossless compression to fit a 1440p 240 Hz signal within DisplayPort 1.4 bandwidth. The HDMI 2.1 inputs support VRR on consoles. There is no USB-C video input.

LG
USB and audio—1 × USB 3.0 upstream, 2 × USB 3.0 downstream; 4-pole headphone output (sound + mic) with DTS Headphone:X; optical digital audio out (S/PDIF)

There are no built-in speakers. DTS Headphone:X gives virtual 3D audio over headphones.
