I'm running 3 monitors on a Saphire HD 5770. Things sometimes get pixilated and my main monitor will sometimes flash in and out for a second but in general it works. 2x DVI and 1 active DP.

You cannot use 2xdvi and 1xhdmi at the same time since one of the dvi outputs shares a channel with the hdmi output.

Your best bet is to use 2xdvi and get an active (!) DP to DVI adapter. You absolutely NEED to use one of the DP outputs to make eyefinity work.

Also, the third monitor won't be recognized untill Windows has booted up, this is normal. During startup you will only see 2 monitors active.



Am using 2x DVI ports and the 3rd connected up with a DP and an active DP -> DVI converter.

During boot it would show 2 monitors, they cloned eachother.

Once it hit the actual login screen all the monitors would go "black" but still lit up, moving the mouse around like they were switched on would make whatever montior the mouse was meant to be in light up slightly more than the other.

Unplugging the DP would "reset" something and one of the DVI monitors would show the actual windows login screen as per normal.

From then on in reconnecting and re-setting up of the 3rd monitor takes 30mins and multiple reboots.

I tried typing my password in as per normal to see if everything would go right after windows had loaded but the 2 screens remained black with the 1 still in powersave mode

Sounds like you've got a dodgy active DP-DVI converter, Cyp.

I ran this loadout on a 2GB HD5870 for about 6 months with a pair of DVI connections and one active DisplayPort to DVI converter.

Eyefinity is pretty twitchy to be honest, and can be really buggy. It also won't work if you're not using the DisplayPort connector, as eyefinity always uses the monitor connected to this as your primary display.

In the 6 months or so I was running eyefinity I had the same issue you have there several times and had to re-configure display groups repeatedly and sometimes replace drivers to get it to work correctly. The performance was also pretty dire in most games unless you dialled the graphics back.

I'd suggest that if you want to run three displays in any decent way, you're far better of with upgrading your motherboard and looking at a dual card SLI solution. I upgraded to a pair of 3GB Palit GTX580s and they're outstanding. Haven't had a single issue with them since they were installed.
