VRR
YES - NVIDIA G-SYNC Compatible, AMD FreeSync Premium Pro. LG footnote: G-SYNC Compatible / VRR supported on GeForce GTX 10 Series and higher over DisplayPort, and GeForce RTX 30 Series and higher over HDMI 2.1 (a VRR condition, not a general output requirement). (confirmed)

Notes
Dual-mode panel: 3840x2160@240Hz (native) and 1920x1080@480Hz (dual mode, forces DSC on). DisplayPort 4K/240Hz runs with DSC active (TFTCentral hands-on). LG’s own hosted PDF manual was not reached this pass (JS-gated download); intermediate PC timing-table rows are Grade D (B&H + ManualsLib cross-check) and only the headline modes are Grade A/C. HDMI "full 48 Gbps" is a Grade-C claim (DisplayNinja) that LG does not confirm - HDMI input link rate left UNKNOWN. LG’s footnote "G-SYNC Compatible on GTX 10 Series+ over DisplayPort, RTX 30 Series+ over HDMI 2.1" is a VRR / G-SYNC-Compatible condition, not a general output requirement - it is recorded as a note and deliberately NOT modelled as a gpuGenerationRequirement gate (PHASE 3C.2B correction G): the schema cannot scope a requirement to VRR only, and a general gate would wrongly block valid non-VRR modes for older GPUs.
