Monitor not being detected after going into standby mode.

When my pc monitors go black once I'm afk for a while often times my main monitor won't be detected when I move my mouse and I have to unplug the display port and plug it back in for it to be picked up.


The problem monitor is a: AOC 27G2G5 running at 1920x1080 75 hz.

Second monitor is a dell S2309W running at 1920x1080 at 60hz. 


My system specs:

AMD Ryzen 5 3600 6-core

16Gb RAM Corsair Vengeance

GTX 960

MSI B450M Mortar MAX mATX mobo.

Not sure on make of PSU but its 650W


I'm not really in a position to test different cards or monitors but this issue has only occured with this monitor and not my previous one. Any help would be appreciated thanks

I also have this problem, however the AOC 27G2G5 is my secondary monitor and won't reconnect after a long sleep mode. It must be a monitor issue, I haven't found a solution yet.
