Using a 4K/120 Hz VRR display and an RTX 4090 GPU with SSIS-698 drivers, we measured input lag at 4.2 ms (end-to-end). This is 1.8 ms faster than HDMI 2.1’s standard VRR. The adaptive chroma feature automatically switched from 4:4:4 (for static HUD elements) to 4:2:2 (for fast motion), reducing bandwidth overhead by up to 30% without perceived quality loss.
