Running Win Vista 64-bit, Core 2 Duo E6550, Evga nForce 680i LT mobo.
I just purchased an MSI 4870 1gb. It has one VGA, one DVI and one HDMI port on it.
I have it hooked up to a 22 inch LCD (main) and a 19" LCD.
I used to have both hooked up to dual dvi's when I ran an 8800gt and they ran fine.
The card runs great except for the DVI port. When I plug my DVI cable from either flat panel to the DVI port on the 4870 I get no signal no matter what I do.
I am running Catalyst 9.5 and I can't understand why I can not get this DVI to work.
I have checked the "Reduce DVI frequency on High-resolution displays" and it does nothing. I also checked the "Alternate DVI operational mode" and both together also doing nothing.
I have also tried 59, 60 and 75 MHz; they do nothing either
However if I use a DVI-VGA converter and use the VGA connection on the LCD it works ok on either at 59, 60, and 75hz, looking the best at 75hz.
Eventually I would like to have the 22 hookup with HDMI and the 19 with the DVI. But I need to get this DVI working....
Does ANYONE have a fix for this????
