Here's my config:
ASUS RX480 8G
ASUS Z170i Pro-gaming mITX
32GB G.Skill 2400mhz DDR4
2TB Seagate HDD
2 I-Inc (Hanns.G) 27" monitors running at 1920X1200
I have monitor 1 (left) connected to the DisplayPort and monitor 2 (right) connected to the HDMI connector.
When I boot, monitor 1 shows no signal while monitor 2 displays normally.
At the desktop, monitor 2 is still correctly the extended display, however monitor 1 is still no signal. I can move my mouse to the left screen (monitor 1).
If I unplug the DisplayPort and plug it back in, that usually fixes the problem, but sometimes it freezes and i have to reset; upon reboot it works fine.
This only happens at boot. After it's fixed, both monitors are fine for my whole session.
Any ideas what's going on?
