Trying to run two graphics cards in Win 7 !

I want to run my desktop PC off an NVIDIA graphics card that I have installed but - on the limited occasions I need to - run a hdmi PC to TV link from an AMD card that I also have installed and which has the necessary hdmi connection and on-board audio.

How do I do that under Win 7 ?

I have an AMD control centre program that shows the two "monitors" and correctly identifies the 42" Plasma as one of them but all I seem able to do is duplicate AMD settings across both screens which leaves me with massively too high resolution for my PC. I can't seem to appy different settings to each screen, let alone run one screen from AMD and one from NVIDIA.

Both cards are showing as fine under Device Manager but I can't reach my NVIDIA card via the NVIDIA software as it says I'm not connected to it !

Any ideas ?

Not sure what the difference is !!!

When I watch TV via the hdmi link, I will only be watching the TV but I'll need access to the PC to set up whatever I'm watching so I guess I need the HDMI output at HD resolution but the PC showing the same but retaining standard desktop resolution !

Sorry for the confusion caused and thanks for all your considerations !

I don't really care what is connected to what to be honest - all I want to be able to do is occasionaly watch online streams via a HDMI link to my Plasma TV without screwing up my PC.

I had this all working fine under XP but since upgrading to Win 7 last week, I haven't been able to work it out.

I can certainly output via the HDMI cable with sound but initially it only gave me a plain Windows background. I was then told I needed to select "duplicate" (or similar) in the AMD software which did the trick but left me with a ridiculous hi-res PC monitor that eventually became unresponsive.

I thought the answer was to make use of both graphics/video "cards" on the PV but maybe thats not the way to go. I only wish I knew how it worked under XP because it was perfect and I've changed no hardware since !

I downloaded latest Win 7 drivers from both AMD and NVIDIA

No !

Still don't know how to achieve different resolution ouputs.

When I tried that, I simply lost everything from my PC monitor except a blank windows background ..... I had to then get back by using the distant TV to change settings !!!

The TV is across the loinge so I can see it and I'm trying to do all this via the AMD VISION Engine Control Centre and the DISPLAY screen in the Windows Control Panel.

Is this guide with screenshots any help (or I may have lost the plot)?
