No signal on DVI monitor from ADV7513

Does the ADV7513 only accept video input that matches CEA861 standards or will it accept others with the correct settings? We are using the OV2643 and have yet to be able to find settings between the OV and the ADV that will display on a DVI monitor. Or is it simply that the ADV converts these signals, but that they end up as a resolution that the monitor is incapable of displaying? We do see signals on the TMDS lines with a 'scope, but the monitor says, "No Signal."

 

We have sent a signal from another source with the 640x480p CEA861 standard timings and the ADV converts and displays this on the monitor, so connections, etc. seem to be correct.
