Eyefinity headaches..

[paulstung]

I have finally got my pc up and running and have dug my monitors out, to give eyefinity a go.but so far what a nightmare. The process of setting it up went great, until I exited CCC, and then there it was. Only one monitor had a full screen image. T add to that the screen with the full image, is displaying a lot sharper and smoother. Thats with eyefinty on with a 5760 x 1080 walpaper, and with extended display.

I'm running 2 x HD 7950's i5 4670k all under water. The cable set up is and my monitor has 2 x HDMI and a display port, my GPU has 2 x Mini display port, HDMI and a DVI.


display port to display port.
DVI to HDMI
HDMI to HDMI


I've also tried

2 x display port to display port
DVI to display port.

I'm at a loss what to do, I have never set up an eyefinity group. Please help guys..

Have you got an active adapter in there?

When eyefinity was first released the 3rd monitor had to have a special adapter so you could enable the stretched display.

I had all the right kit and sometime it could be a complete ball ache to get running, its also the main reson why I use a high res single screen for reviews now, that and the amount of games I had to add patches too to get working correctly on 3 screens - imagine installing and removing these patches EVERY review.

Its a complete ball ache - but start with an active adapter, if youre just running cables then I think thats your problem

A ball ache indeed, the bloody triple stand was a great big fat hairy ball ache then. Bloody thing.

For some reason I thought that you only needed an active adapter if you didn't have a display port output on your monitor. I will certainly give it a go though mate.

I wish I had gone for a larger single screen now. We live and learn.

I thought so according to AMD you only need an active adapter if you haven't got a display port out on you monitor

( Taken from AMD website )
Connecting multiple monitors for AMD Eyefinity technology couldn’t be simpler. There are four easy rules to remember:

The first two monitors can connect to the graphics card with any display output on your product: HDMI, VGA, DVI or DisplayPort.
The third (or greater) display must be connected to the graphics card via DisplayPort.
If your monitor does not have a DisplayPort connection, you will need an inexpensive active DisplayPort adapter for it. DVI to DP adapters can be had for less than $30 USD.2
Every family of GPUs supports a different maximum number of displays

When I did it my monitors were all DVI

As Ive said it was always a mare so I sacked it off. Even Orca is set up with the screens individually although this is a workstation

I'm going to try an active cable to be on the safe side, and try all 3 monitors with DP out to 2 x MDP, and 1 DVI.

No need for the active cable, it was an under scanning problem. All sorted now. Cheers any how Tom.

If the third display is native display port to native display port, that should be fine. Active adapter is needed when trying to convert from a different type to display port. I had issues with my setup. I had to turn one screen off and leave the other 2 on. Then eyefinity would enable correctly. Finally, turn the third screen on and good to go.

Now I'm with surround and just have everything hooked with DVI. 2 on the first card and the third on the second card. So much more flexible.

It's all up and running like a dream now mate. It was an underscan problem, I had to disable eyefinity, and do it monitor by monitor, and then reconfigure the group.
