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.

Will a splitter make duplicated displays or an extended display? – user51210 – 2011-09-15T03:45:01.827
If its just a splitter, then duplicated displays. However if your willing to spend significantly more, you can buy a device that essentially has its own graphics card, that lets you use an extended Diplay. – wizlog – 2011-09-15T05:39:25.423
An alternative if you have another computer to waste, is http://synergy-foss.org/ It lets you use your mouse/keyboard across another computer.
– Duall – 2011-09-15T06:41:24.677@wizlog, will the device that essentially has its own graphics card disable the on-board graphic card? because I can connect the original on-board card with 2 monitors with both working, and I just want one additional port that can be used for the 3rd monitor. – user51210 – 2011-09-15T12:28:24.537

OK, that is a dedicated graphics card which allows you to connect two monitors via DMS59...
I am trying to connect a third monitor, but it disables the original on-board graphic card.
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:
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').
So is it Is it possible to connect 3 monitors with Dell Slim Studio 540S?

The operating system I have on the Slim Studio 540S is Windows Vista, not Windows 7. Can I still set it up in BIOS to make both the on-board graphic card and the new card work? – user51210 – 2011-09-15T12:17:39.733
