Hook up & run 3 monitors

Asus Eah5670/di/1gd5 radeon hd 5670 grap...

Specs: Windows xp, amd
I want to run 3 monitors - each are DVI / VGA input.

I have a ASUS EAH 5670 ATI card with dvi, vga, hdmi outpust installed in PCI E slot - this is currently running 2 LCD monitors.

I have no more PCI E slots open.

I have one PCI slot open.

Can I buy a cheap PCI video card to the open PCI slot to use for the 3rd (dvi) monitor?

Does this PCI card also have to be ASUS? Or it just has to be ATI not Nvidia?

will both cards work together at the same time? I need them to work in extended screen mode...spanning...where each screen has different windows.

This is a shot in the dark, but why not utilize your third hdmi output on your card with an hdmi to dvi adapter like this http://www.amazon.com/HDMI-Adapter-... Then down load and install a program called mutimon.


Should work. Let us know.

tried using hdmi to dvi adapter...but problem is... not all 3 ports can work at the same time.

either hdmi can run...or the dvi and vga. all 3 cannot run at the same time.

I understand you can use an additional pci card, but I don't remember where I saw it. Try a google for triple monitors.

Even the best standard PCI card can't compare to the performance of your HD 5670, so keep that in mind.

The 3rd monitor will ONLY be used for Web surfing / e-mail checking. Nothing graphic intensive at all.

So, I just need a cheap easy way to hookup the third monitor.

I am thinking of buying a PCI card....but do I have to buy an ATI brand since I have an ASUS ATI HD5670 installed in PCIE ? do they have to be both ATI to function properly with 3 monitors?

Or can I get any brand pci card and it will work with my existing ati 5670 ?

I would stick with ATI so as not to have conflicting drivers. Another option would be to buy a card that supports 3 monitor setup.

grass - buying a new card to support 3 monitors is not an option for 2 reasons:

1. I already spent $150 on the ATI 5670 and I only have one PCI E slot in my PC

2. A 3 monitor card would cost well over $50 ? I can get a PCI card for $50 or less?

Again, the 3rd monitor is just for web browsing...no games, no graphics etc.

I have been running multiple monitors for years. I can't get deeply into the weeds on this topic but I can assure you that my problems all went away when I went to an identical chipset video card as my second. Of course, this is only possible if you have multiple PCI express slots.

I actually have three ATI HD 2600 XT video cards running on my gigabyte motherboard. I have four monitors sitting in front of me and a fifth which is a 55 inch Sony television running on the third video card. It works – and the reason that it works in my opinion is that all cards are running on the same video driver.

At one time I tried to go the route that you are attempting which is to add an inexpensive PCI card for my third and fourth monitor and it just didn't work. This may not be the answer that you want but I'm pretty sure that it is the right answer.

I don't know if you still need an answer but I think I have one for you:

With ATI, you need to run one monitor through displayport if you want 3+ monitors. If the 3rd monitor is not displayport, then you need to run the monitor from the displayport using an ACTIVE displayport to dvi cable. Accel sells one - you can find it on Amazon.

I haven't tried this myself yet. My cable will arrive tomorrow. But my research has led me to believe this should work as someone who bought this cable on Amazon had exactly same problem and resolved it with this cable.
