Brightness450 nits typical; 600 nits peak; HDR 600 DellTypical 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
Rated contrast3000:1 native contrast

IPS Black targets darker blacks than conventional IPS; it does not give per-pixel black like OLED or local-dimming displays.

FirmwareM2T102 (A01, 19 August 2025)

Dell says it targets wake-from-sleep, USB dropping to 480 Mbit/s on MacBooks, auto brightness/colour temperature sensing and daisy-chained displays not waking.

Panel—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 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
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
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.

LG
Stand and mounting—Tilt, height, swivel and pivot adjustment; VESA 100 × 100 LG
