How to wake up mac monitor from sleeping

Then select 'Energy' settings and then select 'Reset Energy Settings'. To do this, open the 'Menu' settings on the monitor (click twice on the second button up from the power button). What finally resolved the issue for me, was to 'Reset Energy Settings' on both the monitors. The issue did not always persist to the same monitor though, I would randomly have to power cycle each monitor. This would happen multiple times a day, it was routine. Whenever waking from sleep, only one monitor would wake, to wake the second monitor I would have to power the monitor off and back on. I swapped the DP cables out for mDP cables hoping that might fix the issue, no the issue remained after swapping out the cables. The monitors were connected using DP cables (not daisy chained, each monitor connected to it's own port on the MBP), MST off, resolution 3840x2160 60Hz. I have 2 P2715Q monitors connected to a 13' 2015 Macbook Pro, and have been struggling with wake from sleep issues with both monitors randomly over the past 18+ months. I think I may have a solution, although my setup is different from yours. So what do I have to do to get the Rev A01 monitor exchanged for one that doesn't have the issue? I don't want to spend the next few years constantly pulling the power on this thing to get it to wake up. The Rev A05 monitor - does not have the problem. The new monitor is a Rev A05 - the monitor I bought with the system is a Rev A01. Well I decided that I was going to go dual monitor on this system - so I bought another P2715Q, which just arrived today. I wasn't sure what the problem was at first - and then I did some searching and found posts all over the internet about the wake up problems. So last week I got the system setup again - hooked up the P2715Q monitor - and when the system went to sleep, I couldn't get the monitor to wake up. I remember when I first put the thing together - I did have a huge amount of issues getting the monitor to wake up, to the point where I just hooked another monitor up to it. I have a Dell Precision 5810 workstation that I bought over a year ago - and just never had a chance to setup.
