An input device includes a proximity sensing panel including sensor electrodes and a proximity sensing circuit. The proximity sensing circuit is configured to acquire, for a sensing frame, sensing measurements of a sensing region using the sensor electrodes, process, for the sensing frame, the sensing measurements to obtain positional information, transmit the positional information to a processing system, and receive, from the processing system, vertical synchronization (Vsync) signal wait information responsive to the positional information. The proximity sensing circuit is further configured to adjust a sensing delay according to Vsync signal wait information.
