1. An input device comprising:

  • a plurality of sensor electrodes;

    a display device comprising a plurality of source lines integrated with the plurality of sensor electrodes; and

    a processing system operatively coupled to the plurality of sensor electrodes and to the display device, the processing system configured to;

    operate in a first mode to update the display device at a first display refresh rate and drive the sensor electrodes for capacitive sensing at a first capacitive sensing frame rate during a first display frame, wherein the first capacitive sensing frame rate is greater than the first display refresh rate; and

    operate in a second mode to update the display device at a second display refresh rate and drive the sensor electrodes for capacitive sensing at a second capacitive sensing frame rate during a second display frame, wherein the second capacitive sensing frame rate is greater than the second display refresh rate, wherein the first display refresh rate and the second display refresh rate differ by a first amount, wherein the first capacitive sensing frame rate and the second capacitive sensing frame rate differ by a second amount, wherein the second amount is less than the first amount.
