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.

Refresh rate and response—165 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.

LG
Brightness and HDR—275 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
Sync—NVIDIA 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
Inputs—2 × 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 PbP—PIP 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.
