I have tried out a few different monitors recently, but I just settled on the one I want to use. All was going well but after it wakes from "sleeping", the windows are being resized and moved. Perhaps there is some issue with drivers from the other monitors messing things up?
This seemed to fix it. Had to adjust the "simulated" related keys. In my case however, there were 3 of these (probably due to the various monitors I have used on it). I just adjusted those to the native resolution as well as the "stride". I found the correct value from one of the other keys.

what iv learned about this issue for the past few years is this...
yes its drivers - but it's also windows and monitor hardware... so one side fix may not be the entire answer.
the only way i've been able to solve the issue is with a "deadhead" or dummy plug with an output to a real monitor.
if you do a search for - Virtual Display Adapter HDMI EDID Dummy Plug - you'll get your fix.
a small simple plug that goes in line with the monitor plug and keeps the "line" alive even when the monitor goes off / gets unplugged or otherwise.
in my scenario everything worked fine until i awoke my screens (i have 5 on my setup) and one would be "re-found" every time, and reset my window positions...after the plug everything works perfect.
they sell for as high as $20 each but i found them on e-Bay for under $10. with many options for what plug type needed - vga, hdmi, dvi, displayport.
hope this helps someone as iv been dealing with it for years and finally can sleep at night knowing my powersave is working...lol
