Just got a new 4k monitor and I cannot get the DisplayPort connection to work between my AMD and my the monitor.


It says "no signal detected"


The documentation for the monitor says the minimum Graphics card for DP is "R7 or higher"


I'm running an R9 270 so this should work.


I'm using the DP cable supplied with the monitor. (by the way, the HDMI  and DVI connections work fine)


Any ideas?
