Thanks but I guess I'll have to do some experiments on other workstation.
Will report here as soon as my download will be available.
I use nvidia and it took me about 2 hours of fighting before I finally came across the answer. I had to download beta drivers (from nvidia). When I got gforce experience working properly (before windows could update my drivers again *sigh*) I had it check for newer drivers and since then everything has been working properly with multi-screen.
With ATI I would assume that there are probably beta drivers you just haven't used yet (only speculating as I haven't used an ATI card in many years).
Yeah I had the W10 driver from AMD(15.7) but I still couldn't get it running. They have since released 15.7.1 so maybe they fixed it. For now though, since we have a year to upgrade, I will just stay on Win 7 and keep happily gaming
I figure they(both companies) will get the surround screen/driver issues sorted out b4 too long.
