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
