1. A display device, comprising:
a light source;
a scanning mirror system comprising a mirror, the scanning mirror system configured to scan light from the light source in a first direction at a first, higher scan rate, and in a second direction at a second, lower scan rate; and
a drive circuit configured to control the scanning mirror system to display video image data by
providing a control signal to the scanning mirror system to control scanning in the second direction, and
for each video image data frame of at least a subset of video image data frames, combining the control signal with an adjustment signal prior to reaching a last active pixel of a current video image data frame to adjust the scanning in the second direction by shifting one or more of a position of the mirror or a trajectory of the mirror for a scan of a next video image data frame to start at a correct location, the adjustment signal comprising a low pass filtered signal with a cutoff frequency based on a lowest resonant frequency of the scanning mirror system in the second direction.
