I have a Powercolor HD 6950 and 3 x Asus vh236h monitors in Eyefinity.
When I am at the desktop, if I move a window horizontally to my far right monitor, there is a line through the screen and the window is 'split' into two connected pieces. One half is on top and one half is on the bottom.
The two halves do not line up until I stop dragging the window, or until I move it above or below this 'split' line.
The 'split' line seems like it is not isolated to one specific lateral line on the monitor; it can be higher or lower on the screen.
I have also noticed these 'splits' when gaming.
Does anyone know what could be causing this? GPU? Monitor?
Most probably the GPU. Low Video memory could also cause this. I hope you're using a >=2Gb 6950, 'cos most probably you're running all three monitors @1920x1080
And that works out to 5760x1080..... Heavy stuff....
It is likely tearing as a result of the 3 screens not having synced up refresh times. The desktop normally always has it synced, but if you have 3 monitors and they aren't synced, you'll get tearing. I've seen others have similar issues due to not having all 3 monitors using the same connection type.
yep, bystander is right. I've heard of this before as well, even some reviewers complained about it. Has something to do with different signaling/timings among the plethora of connection types used on those boards.
It might get fixed through drivers at some point, or not.. eyefinity isn't quite finished yet. *rolleyes*
So there's nothing actually wrong with your hardware as far as I know. Ideally you would need to use connections of the same type, but that means using 3 DP's and that isn't going to happen anytime soon. Even though the card supports DP1.2 and monitor daisychaining and DP MST hubs, neither are available.. (hubs or 1.2 capable monitors)
edit and if you google 'eyefinity tearing' you'll get tons of forum threads, some with weird solutions to fix it...
