Many times the integrated video chips don't offer the same resolutions as the stand-alone video cards. Yours may not be sending a resolution that the Barco can accept. Check your computer or mobo's documentation and/or nvidia's website for the resolutions and scanrates supported by the chipset. You may also want to try Powerstrip to see if it can set custom resolutions with the integrated chipset.

If the onboard VGA definately has RGB on it there a two possibilities left (since the RTC2200 appears to work)
1) The H and V sync amplitude of the onboard VGA is not high enough (very unlikely) for the RTC2200 to recognize it (there is no quick fix for this)
2) The H sync of the onboard VGA is much narrower than the sync of the video card. To fix this, open the RTC2200 case and move the jumper from JP5 to JP6.
