Panel31.5-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		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
Brightness and contrastHDR 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.

Colour and HDR99% DCI-P3; HDR10 and Dolby Vision; VESA DisplayHDR 400 True Black; factory calibration e-report ASUS98.5% 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
SyncAdaptive-Sync; FreeSync Premium Pro; G-SYNC Compatible; ELMB

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

ASUS		—
Inputs1 × 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		—
USB and audio3 × USB 3.2 Gen 1 Type-A hub; KVM switch; earphone jack; S/PDIF optical out; no speakers

KVM lets two computers share the same keyboard and mouse through the monitor.

ASUS		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.

OLED careASUS OLED Care; proximity sensor; flicker-free

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.

ASUS		—
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
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.
