MP 6,1 Display wake issues MP 6,1

[rawweb]

My 6,1 is having issues waking from sleep in 10.14.6 Mojave with dual DELL P2415Q Displays. The computer is physically awake but doesn't display an image unless I switch off one of the monitors and then back on. Any thoughts on if I'm doing something obviously wrong?

 

[s.m.t.]

I had P2415Q before I got a P2715Q... With the 24" I would have issues getting signal after powering off the monitor (no sleep on the Mac) with my 4,1... I would have to pull the power cable (or flip the switch on the power strip) going to the monitor for it to get signal again. I think there was an issue with those early 24" displays (rev 00 or 01)... I think there was even a thread on here about it...
