Problems with R9 290 and Dell P2715Q.
The monitor is connected with DP.
The problem is, I have no picture on the screen in windows 10. ( screen go in sleep mode )
When I boot the pc I get the bios test / hit Del / f2 for bios, I also get the windows 10 boot logo on the screen.
But when windows 10 is loaded and you have to log in, the screen go in sleep mode.
It looks like a driver problem in windows 10 ??
I have installed the newest drivers from AMD ( Crimson 15.12 )
If I connect the monitor with HDMI it works all the time no problems.
