How many outputs can I use on an XFX 7870?

post #1 of 11
Thread Starter 
I have an XFX "Double D" 7870 on the way. It has 2 DVI ports, an HDMI port and 2 display port outputs on it, and I'm wondering how many of those outputs I can use at one time?

I know the Nvidia Kepler cards can drive 4 outputs/monitors off of one card, but I'm not sure if AMD cards can... know that some AMD cards lack the ability to use both DVI ports and the HDMI port at once. Does this card have that limitation? Or can I use these outputs to drive 4 or even 5 monitors?

the reason eyefinity is called eyefinity is because you really can use an infinite amount of monitors

in your case it can support:
1 monitor from dvi
1 monitor from the other dvi
OR...
1 monitor from hdmi
(can only use either 1 dvi/hdmi or 2 dvi)
2 monitors from one Displayport
2 monitors from the other Displayport.

That adds up to...

6 monitors

Btw each displayport can support 2 monitors by daisy chaining

So I can use both displayport outputs and two of the three DVI/HDMI outputs simultaneously

Got it

Shame, displayport inputs on monitors Are still pretty rare. Being able to use all the DVI/Hdmi outputs at the same time would be nice

You can always buy an adapter to use one of the displayport outputs. That's what I'm doing at the moment for a triple screen setup

Of course, but adapters aren't trivially cheap. smile.gif

They're not 5 bucks true, but not 50 either wink.gif
I got one for 25 bucks. Works outstanding and solves my problem permanently.

At this juncture, it may be prudent to mention that I've written an extensive FAQ for Eyefinity: www.amd.com/eyefinityfaq -- most of the questions in this thread are answered there.
