I'm currently running a triple monitor setup with two 1080p monitors using DVI and a 1440p monitor using Displayport.


Frequently, the Displayport monitor will not be detected when I start Windows.  It will show all of the startup / POST stuff perfectly fine before that, however.  But as soon as it gets to Windows, it tells me that there is no signal.


Physically disconnecting and reconnecting the monitor to the video card causes it to be detected and mostly work like normal.


This has been happening for a couple weeks.
