Hi

I have browsed this forum for over an hour now looking for a solution for my dual monitor problem, still no luck!

I want to use 2 dvi->hdmi cables to connect my monitor and my TV (both got 1080p resolutions) but I can't get them to detect at all in windows. I only get the first one.
So I know the cables are good, the screens are good and that the card is supposed to support this. I have no f-ing clue why this is not working. I got a mini hdmi output on my card aswell but I cant use it since the adapter that I got with the card does not work when I have to use the dvi port next to it.

After running the tutorial found here:

http://www.sevenforums.com/tutorials/7947-force-dvi-hdmi-resolutions-refresh-rates.html?ltr=F

I can run my monitor on vga (after a dvi-vga adapter) on the correct resolution. so this shows that both dvi ports on the card are correct (I think). So why the **** can't I use both div connections at once?

Not sure with Nvidia cards but with ATI/AMD cards, when you use the HDMI port, you loose one of the DVI ports, since they are the same except sound from the HDMI. As to which DVI port is port 1 and port 2, I'm not sure. Does your TV have a HDMI port? If so, go HDMI to HDMI to GPU for the TV and then go DVI to DVI for the monitor. Then trail and error as to which DVI port is 1 and 2 on the GPU.

According to the GPU manual the dvi port next to the hdmi port is port number 1 and because its to close to the hdmi port I can't use port 1 and the hdmi port at the same time. This port always gives picture, the dvi port number 2 only detects my screen if I use a dvi->vga cable and this is what I want to avoid. (I hope you can make sence of my rambling)

way too much to list this one of 11 computers we run.
Update: I'm talking to nvidia about this matter and they gave the advice that I should reinstall my drivers while in safe mode, going to try that when I get home. Will update this post when I have done this.
