I know I should be able to do this as it would only take about 201MHz to accomplish this, or that is what I belive is supposed to happen. However, when I try to do this, the image will not capture.

I ran Datapath's application called RGBHelper that comes with the downloaded driver and application package from their site, and it shows that the signal shows as DVI-SL. I tried patching the card to remove it's limitations, and tried to write in a custom block that would hopefully show the video card as HDMI instead of DVI-SL. In the end it will not show up as anything other than DVI-SL.

It's possible the video card is only sending an HDMI signal for TV resolutions, although I don't think that's the case. Try adding the LPCM audio format. If there's audio, then it's definitely HDMI. Let me know if the dongle changes anything.
