I've got a Displaylink USB DVI adapter and am attempting to hook up an RCA HDTV as a second monitor using it's DVI-D input. The only resolution Displaylink is offering is 640x480 with 16-bit color quality. Also, the picture is garbled and full of static, which I believe may be related to an incorrect refresh rate (I could be completely off base here, just a guess). Can someone point me in the right direction to resolve this issue? I'm running Windows XP, and I've attached the logs from the debug tool.

Thanks in advance.

This looks like an interlace TV< and we only support progressive modes. The modes reported by the TV are:

Display Modes
=============
640x480x24@60
720x480x24@60
1920x540x24@60 - rejected due to being Interlaced.

So you should get offered 640x480 and 720x480. I see you are running SW version 5.2. Could you update to v6.3 and see if this fixes the timing issues at 640x480 and whether 720x480 becomes available?

Hi Wim,

Upgrading to 6.3 did the trick! I had tried using the in program auto-update (which didn't seem to find anything), but had not manually checked the website for a newer version. I'd be lying if I said I wasn't a little disappointed that I can't get the full 1080i, but 720x480 is actually pretty viewable. Thank you very much for your help.
