How to use three monitors with Radeon 5570?

I recently got a new computer and two new monitors. I had the 3rd monitor working before but now nothing will show up when it is connected. I have two hp 2009m's and a 24 inch Asus. The Asus is hooked up to the Display port with a dp to dvi adapter that i bought off ebay. The left Hp is hooked up to the dvi port and the right one (this is the one not working) is hooked up to the Hdmi with an hdmi to dvi adapter. Now like i said before i had all 3 monitors working before so i don't think it's an issue with the cables, Not sure if it matters but I was using two dell 17 inch ultra sharps and one of the hp 2009m's when it was working. So does anyone know what the problem is? I really don't feel like putting much more money into this so if i could make it work with what i have that would be awesome. Thanks

In CCC is the 3rd monitor enabled?

How do you enable it? All i see is duplicate, extend and replace. I tried to extend it but it disabled my 2nd monitor.

When you hook up a monitor to the HDMI port you loose one of the DVI ports. That is why your third monitor is not showing up in the CCC. The connection set up should be two monitors connected to the two DVI ports and third connected with you display port adapter to the display port.

Are you using the same 5770 from your old computer or did the new computer come with a new 5770?

Its the same one, i just took it out and put it in the new computer.

To enable the use of 3 monitors, you must have one monitor connected via DisplayPort.

In Catalyst, you have to disable two monitors then create a display group. You can choose: 1 x 2, 1 x 3, 2 x 1, or 3 x 1; where the first two options are for a super tall setup and the latter two options are for the super wide setup.

(Unfortunately, I'm not at my personal pc so I cannot provide screenshots at this time)

That would be great if you could post up some screen shots so i know what to do.
So it would make the computer think its just one large display

Is that display port adaptor an 'active' or 'passive' adaptor?

Eyefinity needs an 'active' adaptor to create a group.
