I just installed my new ATI HD4870. Problem - The video shows up via DVI when the machine posts and starts to boot up to windows. Then it will stop sending a signal to DVI port. S-Video works fine. I am running Vista x64 will all the latest ATI drivers installed. Any ideas what is causing this? Thanks in advance!
I am using a Dell 2001FP monitor. I boot to safe mode and turn the resolution down to 1024x768 just to make sure, then boot back into windows and it goes out right have the green Vista bar runs across the screen. You can hear the audio so it is up and running, and I can RDP to it just fine.
I can get it to work with the default Vista driver through DVI, but right after installing ATI drivers and rebooting I get this issue. I'm just saying I won't be surprised if it does the same thing. I sure hope I am wrong though.
