Hi,

I've searched Google but can't find a clear answer.
Is it possible to put 2 different video cards into a PC in order to hook up 3 monitors?

Motherboard: ASUS P8P67-M
Slots:
1 x PCIe 2.0 x16 (blue)
1 x PCIe 2.0 x16 (x4 mode, black) >>>>>> USED by current video card
1 x PCIe 2.0 x1
1 x PCIe x1
others are empty.

If possible, are they things i should be aware of when buying the second card? The current card is not a fancy one, the seconds doesn't need to be either, they screens won't be used for gaming.

Thanks

Yes, depending on the OS you'll get better results from Windows 7 or 8 then you would from something like Windows XP but it can still be done.

You can even run PCI Express + PCI (although the performance on the PCI would be less)

You can even run display through USB if you're not willing to buy another card to put into the machine.

the answer is : it depends
bnasically, yes you can use 2 cards for 3 monitors - but if the card takes 2 PCIe - width, it maybe impossible to install a second card in the 2nd  x16 slot
what card do you have, and how much monitors now?

also -  check how much Power you need for the new setup here :

Why not use a single display adapter that supports three monitors?

About a year ago I set up a customer with an nVidia GTX550-based adapter that has two DVI ports, one VGA port, and an HDMI port. He runs a large monitor on each type of port, and has had no problems with the setup. I don't know if the system would support a fourth screen though...

I have a ATI 5770 that supports eyefinity technology. I´ve never used, but maybe you can take a look:

os is windows 7

the card is below in the black slot is a video card with:
1 hdmi
1 dvi
1 vga
but only a combination of 2 ports work. card is nVidia geforce 210

i would rather add an extra card.

so question is, with the 3 empty slots in mind, can i add an extra video card to hook up 1 extra screen and will windows handle that? 2 video cards?

Yes, that won't be an issue, you can even add 2 monitors depending on the second card you buy.

You'll find it far easier to configure if you buy a card that uses the same unified driver your current card does.   Buy a card in the same family ... or even another of the same card you have.

As a matter of interest, why do you prefer that approach to simply using a single Eyefinity card?    [They support 3 simultaneous displays]
