What's wrong with my monitor??

The monitor on the right is the one with green lines. After splashing some colours on paint it only seems to be black and brown that have those green lines on it.

I have a sapphire 6950 running 3 x 22" monitors.

The left monitor is connected via DVI cable
The middle monitor has (mini dp -> dp adaptor) -> (dp -> DVI adaptor) then DVI cable
The right monitor is connected via DVI cable.

I have a feeling that it's not getting enough power through it? the other two monitors have DVI cables with lengths of about 1.5mtr. The right monitor has a 7mtr DVI cable.

Any help appreciated

Did you take the Red pill or the Blue pill? Looks like The Matrix!!.

PS sorry but i don't have an answer to your troubles.

Have you changed the outputs of the monitors?

Could be an output of your graphics card.

I think the maximum recommended cable length for DVI is 5m so your 7m cable is potentially a problem.

You can obviously test this by using a shorter cable.

Is the middle monitor connected with an active DP adapter?

If it's just a passive adapter try unplugging it and see if it clears the problem on the right monitor.

Cable lengths up to 4.5 m work up to resolutions of 1920 x 1200. Cable lengths up to 15 m will work at lower resolutions up to 1280 x 1024.

You can get repeaters and signal boosters which allow something like 50-80 metres.

Do you get same problem swapping monitors around.

Have a look at this link: http://www.amd.com/us/products/technologies/amd-eyefinity-technology/how-to/Pages/set-up.aspx

Does take a few minutes to load, will tell you eyefinity combinations, etc.

That could possibly be my problem, as my resolutions are 1920 x 1080. I shall swap the monitor over with the shorter cable and see if that sorts the problem out. Cheers
