When using the dock directly, I could not use this display since the image would appear too narrow. What I had to do is use a HDMI to component converter, set the dock 480p, then run that into a Gbscontrol. Now I could scale it properly for this display. The only downside is in 480p mode, the dock has small artifacts present in the upper right of the image. Could’t get downscaling to work, which would have gotten rid of the artifacts.
