MSI 8400 nvidia card with VGA and DVI port.
The dvi port drives one monitor and the VGA port is split into two to drive a 32" TV and a 20" screen. This works perfectly with this card as the VGA port is duplicated on the two views.
My problem however is that I need to change the display card and I tried using a Nvidia GT220 and a GT240 card without being able to get all three monitors to work. If both the tv and monitor is plug into the split VGA channel I only managed to see the desktop on the TV. If I unplug the TV, with system still running, the view switches to the other view.
I have spoken to quite a few IT pro' s and no one understands this problem.
Since you are just splitting the signal using a simple splitter, it's only sending the signal to two places after it leaves the card. I don't see why the video card would care one way of another.
You can fix this pretty cheaply though, just get a second low end PCI or PCIe x1 video card to run the 3rd monitor. You can find em for $30 or maybe even less used on craigslist or something. Or you can replace your video card with a faster one that supports 3 outputs without an add-on splitter.
I never liked splitters anyway, they degrade the signal and can only show the excact same thing on both displays using the same resolution.
No, that card will only support 2 monitors at a time, but you can use another card to use a 3rd monitor.
You will also need better software like ultramon for managing 3 displays. That gives you a seperate start menu and taskbar on each display, and easily allows you to move one application to another display.
I have tested the cards with different monitors and can now confirm that it is not the cards. The cards work on a similar setup, 32" TV, 19 & 17" lcd screens. The only thing left to test is the actual vga cables. Do not why the cables would make a difference between cards but hey that is all left to test.
