There are several events that can change monitor identities in windows (Ex: monitor port gets changed). This has cause Plex to start offscreen for me and, in my case, Win+Arrow keys doesn’t grab the window.
I can solve this issue locally by deleting the following entries in the %AppData%/Local/Plex/Plex.ini file:
[ui]
windowX=605
windowY=275
windowWidth=1280
windowHeight=720
screen=\\\\.\\DISPLAY1
These configs seem to get reset on the next load of the Plex Player to the default monitor center screen, so fixes my issue perfectly. The thing is that it’s difficult to remember where the ini file is when the issue happens. Is there a way to reset these settings from the commandline? something along the lines of plex.exe --screen default?
