I just ordered a Dell-U3818DW for my 5,1 to be driven by a Radeon HD-7970.
I suspect, there is no 3rd party tool to control display brightness etc. from the Mac?
Any other tips apart from getting a minDP to DP cable?
I have the system running under High Sierra. It detects the correct resolution, but I see sporadic crashing.
I cannot recover from sleep without restarting.
Any ideas what could be causing this?
[doublepost=1517455134][/doublepost]Working fine under Windows. So it does not appear to be a hardware issue.
I have the NativeDisplayBrightness app working on my genuine Mac mini 2014 with Dell P2715Q.
