Hey all, having an issue here and it's really annoying. Here is the system I just built:

a64 3200+ (No OC)
Biostar TForce 6100-939
BFG GeForce 6600GT OC (Not OC'd yet)
1 gig kingston valu ram
120 gig WD HDD

Here is the issue. Fresh install of XP, screen is all choppy and crappy and such. Install the video drivers and the LCD stops responding (After windows adjusts the display). The LCD works no problem on my Ti4400 machine, using the DVI input. Currently I'm hooked up to a 15" CRT monitor under my desk that is used for testing. Boots no problem, can adjust up to 1024x768 cause this thing can't handle anymore.

I have tried the following:
reinstalled windows, twice
used the NVidia drivers from the CD included and from the website
Hooking up to a CRT monitor, works.
Installing the LCD drivers

going to try using the VGA cable for the LCD if I can find it. Is there anything else that I can try to get this working? This is my first time working with a PCI-e card, not sure if there are and quirks or anything like that.

THanks!!!
 
I'd check refresh rates when setting the res for the LCD. It may or may not be an issue, but it can't hurt to try.
 
I've tried the refresh rates 60, 70, 72, and 75. On the Ti4400 I had it running at 72Hz.
 
Alright, this is a little weird. I tried the VGA Cable instead of the DVI cable and it works no problem. What can cause this? What kind of performance loss can I expect with the VGA cable over the DVI Cable?
 
No performance loss. Just a slight degradation of image quality, chances are you won't even notice playing a game. I'd also probably find someone else with a dvi out, test it on their system and RMA if it's still not working.
