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 ?

But I'm confused here, the OP looks like installed a monitor to the onboard graphic (geforce 7025) while connected a TV to an AMD 4350 card , what I know is that when an extra card installed on the PCI-e slot then the onboard graphic will be disabled.

What Nvidia card does he mean? There are only 2 PCI slots left.

I'd say the proper way is getting an adapter to connect his VGA monitor( I guess he can't connect his monitor to this card because it has DVI & his monitor is a VGA) to this AMD card instead.

I think then that the answer to your problem is that as you have installed the HD 4350 then this has caused the on-board graphics to be disabled, there might well be a setting in the bios to stop this happening but I do not think this is possible on your motherboard but I am still trying to track down the manual.

I maybe misunderstanding this but I think that the OP wants to use the Nvidia graphics card (which may or may not be built in) so that the problem with the resolutions can be solved. I don't think that this will change with a different graphics card. It should be easier to set separate resolutions if an extended desktop is used (two different displays)than a cloned display (repeat of the desktop).

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 !

After installing Windows 7 did you then install any missing drivers? because it is quite possibly a chipset driver issue. Your motherboard is listed here Abit but I seem to be unable to get to the driver download page.

I downloaded latest Win 7 drivers from both AMD and NVIDIA

I wouldn't use the AMD software. See MS Support. Use extended desktop and set the resolution for each.

It should be possible to set individual resolutions under mirrored.

I mentioned chipset drivers not Nvidia or AMD.

Woolwell. I don't think that is what he want to do.

" 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." ie connect an external monitor and get the resolution right. I don't think that changing graphics will solve that if it worked with XP.
