I bought a graphic card, ATI Radeon HD 4350 DMS59 512 MB DDR2 PCIe 2.0 SFF Graphic Card, trying to connect a third monitor, but it disables the original on-board graphic card. So is it Is it possible to connect 3 monitors with Dell Slim Studio 540S?
Windows supports up to 9 displays natively, so its the hardware thats limiting you. Some BIOSs detect that you put in a video card and disable the onboard graphics card. There might be a setting in BIOS to keep it enabled. Look under "integrated devices" or something similar to that.
Another thing to note is that there are known issues in Windows 7 when trying to use 2 different video drivers.
I don't know about using an on board graphics card, but you could buy a splitter, products of that type should do fine.

OK, that is a dedicated graphics card which allows you to connect two monitors via DMS59...

The graphics card can not disable your other on-board graphics. What can happen is that your motherboards firmware (BIOS) is trying to be to smart.
Usually you can use:
- On-board graphics only
- dedicated graphics only
- Or both on-board graphics and dedicated graphics.
What I suspect is that the BIOS detected a dedicated card and tries to turn the on-board off, thus freeing up some more resources. Which is bloody anoying when firmware does this on its own. To prevent this go to the BIOS and set the on-board graphics to 'enabled' (not to 'auto').
