Help? I have a ATI Radeon HD 5700 series display adaptor, and I have been told it supports up to 4 monitors, cant see how, only have two inputs and a sata. Is there an adaptor or something???? I have currently one monitor plugged into the dvi and one into the sata port.

I have taken an image of the back panel, as i cant see how you can attach more than 2 monitors. I am currently running 2, but need to run an extra one.

here is the specs on it, straight from the site.

Any Ideas? Am i missing something (apart from a tech brain!!!!)

First a lone 5770 supports a maximum of 3 monitors by itself. Next you a have a dvi , hdmi , and display port , not a sata port.

To support 3 displays you have to have one monitor capable of displaying with each connection type , hdmi , dvi and a monitor with a native display port.

Thought i would throw in my .02 here aswell.

You can have the first two monitors set up with either both dvi or 1 dvi 1 hdmi. This could also be done with duel-link.

In order to obtain the 3rd monitor you either need to step up eyefinity(only works on newer OSs). or buy an adapter for your display port that runs ~$100.


To my knowledge a single 5700 can only support up to 3 monitors.

Not the monitor on the display port has to have it's own native display port with no conversion in between. If he had that with two on monitors on the hdmi and dvi port then triple monitors would be possible.

thanks for all the advise. I found a few different display port to dvi converters. Guess the easy way to ask the quesiton, some have two connection - ie display port on one end and dvi on the other, however there is antoher that has display port and usb on one end and dvi on the other.......??

I am thinking, from the above advise, that I can run this configuration. So I have a monitor already in dvi and hdmi currently. I will buy this display port converter, and hopefully that will do the trick for the 3rd montior. Will i need to download eyefinity from ATI??



Thanks again guys. really appreciate the help....

I'm sure we are confusing you :(

I believe you can hook 2 monitors up to the DVI out, and the third onto the DP if you use an adapter that has a built in clock (the one with usb).

More info here: Preview - DisplayPort: A Look Inside | bit-tech.net

I am not 100% positive this will work, I have tried to hook up 3 monitors to my 5770, (2 through dvi, 1 through hdmi) and the computer detected all 3 no problem but could only use 2 at a time. hooking the third one up through DP may fix this but i cannot guarantee.

Also, just the DP->hdmi without a clock (no usb) will not work. (i have tried :D)

It appears emosun and i both have the same gpu. if he can confirm that DP will not work i would not purchase one unless you can borrow one or return it if it does not work.

I don't think I can possibly say it more simply , unless the monitor your connecting to the display port has a display port , then you can't run 3 separate monitors on this gpu.

Had to join just to add this, just in case anyone who is trying to run 3 monitors on one ATI finds this thread. I am using a crossfired 5770 to be more accurate. Not a correction per say, just want to make sure it's clear that this is possible on my hardware at least.

You can in fact run a third DVI monitor from the display port using an ACTIVE converter like this:

Picked it up on the egg for 28 bucks and am currently basking in the glory of Eyefinity. :cool:

I've been running 3 monitors on this card for over a year using DVI, DVI->VGA , and Display Port->DVI via an Active Display Port adapter ($26, NewEgg).

Trying to hook up a 4th monitor, I replaced the DVI-VGA with a direct DVI connection and added an HDMI->DVI adapter, so the new configuration is DVI, DVI, HDMI->DVI, Display Port->DVI.

No joy. Trying to enable the 4th display causes one of the others to become disconnected, keeping the total number of active displays at 3. I can't rule out whether the problem is use of adapters as I don't have a monitor which can directly take HDMI or Display Port.
