Refresh rate and response time—144 Hz; 1 ms (GtG, Faster mode)

LG notes that 1 ms is only achieved with Game Adjust → Response Time → Faster. 144 Hz requires a graphics card with DisplayPort 1.4 (DSC) or HDMI 2.1.

LG
Contrast and viewing angle—1000:1 typical (700:1 minimum); 178° / 178°

1000:1 is ordinary for IPS: blacks can look grey in a dark room. No local dimming is listed.

LG
Colour—DCI-P3 95% typical (90% minimum, CIE1976); 10-bit (8-bit + FRC), 1.07 billion colours; hardware calibration ready

8-bit + FRC imitates 10-bit gradations with rapid dithering; usually invisible to the eye. Hardware calibration writes settings to the monitor’s own memory.

LG
Adaptive sync—NVIDIA G-SYNC Compatible; AMD FreeSync Premium; VRR up to 144 Hz

Matches the monitor’s refresh to the game’s frame rate, reducing tearing and stutter. According to LG, VRR needs a graphics card with DisplayPort 1.4 (DSC) or HDMI 2.1.

LG
Connections—2 × HDMI (2.1), 1 × DisplayPort 1.4 (DSC); USB 3.0 upstream 1, downstream 2; 4-pole headphone out (audio + mic), DTS Headphone:X

DSC (Display Stream Compression) compresses the 4K 144 Hz signal, which exceeds DisplayPort 1.4 bandwidth, with no visible loss. There is no USB-C input and no built-in speakers are listed.

LG
Gaming features—Black Stabilizer, Dynamic Action Sync, Crosshair, FPS Counter, User Defined Key; Hexagon RGB LED lighting

Black Stabilizer brightens dark areas so opponents in shadow are visible; Crosshair places a fixed aiming point at screen centre. Crosshair is unavailable while FPS Counter is on.

LG
