No image after turn off

[grandpatzer]

I have had this irritating problem before and after crossfire so is not crossfire related:

I have 3 displays connected, one has DP built in Dell U2311H

Each time I turn off or sleep PC and forget plug out DP cable the system gives dead displays.

so this will happen when forget plug out DP cable and waking pc or power on, no bios image either(!)

is there solutions besides plug out cable?

when I plug out DP cable and wake or turn on PC it works I just plug in cable after windows loads.

Sleeping mode has a lot of bugs . What OS you using ? My sleep doesnt even work.

Ive got windows 7 64 bit, not just the sleep mode also when turning on PC with Display port cable in.

5850, eyefinity with 3displays, 3rd display with DP need to be plugged out until windows loads

also no bios screen either when power on.

I had 10.7 upgraded now to 10.12.

but I think is not driver related bcs also when I power on PC with DP cable plugged no bios image

I have now connected the dell with a VGA-DP adapter and it works flawless.

can someone give me idea how to connect DP-DP from display to video card
