I'm looking for a solution to my problem but I can't find nothing on line.
I have a Radeon HD 5870 Eyefinity 6 with Six mini display port. When I use it with monitor connected it works fine, but if the monitor is phisically disconnected, windows does not startup. I can't see what is the problem, but i'm sure somethings goes wrong. I use this computer for many different purposes: network storage, remote desktop and sometimes for gaming. Actually I use it connected to an amplifier but, when it's switched off, it phisically disconnect the monitor.
So when I wakeup my pc, I can see it on but ping, rdp, vnc, teamviewer etc don't work, and if i try to connetc the monitor again it doesn't still work, so it's necessary to reboot it again with monitor connected.
I've noticed that with anyone other video card, no problems occur.
My Spec: ASUS P5q, q9650, ssd crucial mx550, 8gb DDR2, Enermax 520 Modu 82+, Ati Radeon HD eyefinity 6.
Thank you in advance.
