The user wanted to return the video source to operating at
640x480 but could not manually adjust the screen resolution. To
solve the problem, Epiphan created a custom EDID for the Frame
Grabber that excluded support for 720x400. When the user
uploaded the custom EDID to the Frame Grabber, the video
source returned to operating at 640x480.
