Windows 8.1 triple monitors - can't enable all 3 at the same time

Solution 1:

Before buying miniDP to DVI adapter, I tested with Ubuntu booted from USB and, as was expected - it worked even without AMD drivers, all 3 monitors, like a charm.

So, seems that Windows 8.1 changed some configs and now it try to autoconfig only Eyefinity mode, even if it's disabled, or something...

Also, report this bug to Microsoft would be nice :)

P.S. Problem resolved with miniDP to DVI adapter. Final cable set is:

• DVI
• DVI
• ACTIVE mini Display Port to DVI adapter

Update: [Solution 2] Also works without mini Display Port, just unplug your GPU from Motherboard for some time and then re-plug it and all monitors.
