I am not convinced. Many TVs are broken by design. The EDID data presented on the VGA/DVI input usually does not accurately represent what the TV actually can display.
First try it with the options to ignore the EDID and just send HDTV timed video to it. When it does not want to display that, maybe you have something. But my TV just displays HD in that case.
