An Adaptive Sync SDP allows a DP protocol converter to forward Adaptive Sync video with minimal buffering overhead within the converter. An Adaptive-Sync-capable DP protocol converter indicates its support by setting the related bit in the DPCD register. Computes AS SDP values based on the display configuration, ensuring proper handling of Variable Refresh Rate (VRR) in the context of Adaptive Sync.
