A method includes: displaying, an image on a display by sequentially displaying a plurality of frames of the image, the plurality of frames including a first frame and second frame; performing a first noise sampling scan at a plurality of frequencies at a first time location within a first frame; determining a first frequency from the plurality of frequencies with the lowest noise; performing a first mutual sensing scan at the first frequency; performing, a second noise sampling scan at the plurality of frequencies at a second time location within a second frame of the plurality of frames, the second time location being a different frame location than the first time location; determining a second frequency from the plurality of frequencies with the lowest noise, the second frequency being different from the first frequency; and performing, a second mutual sensing scan at the second frequency.
