Since switching to an UHD display, I am experiencing this very annoying issue, that after locking my workstation and then returning to work, all windows positions are reset to upper left corner and a resolution of ~ 1024x768.
I am using [WindowsKey]+[Left] or [Right] most of the time, to use the left or right half of the screen, but some windows (like explorer, new e-mail, etc.) should keep the size they had.
Could it be an issue with how the display is driven (DisplayPort 1.2, 60 hz)?
The only reference I found about this issue is here
