With this setting i am not be able to get the program window visible. Only tray icon.

Ok.
There are clearly a few mixed issues - one I am convinced is DPI related, and the other relates to why one screen is DISPLAY1 and another DISPLAY6
Second is related to Win-P and turning off/on second screen.

But have rewritten the Display handling code and have a test build here:
https://github.com/Ghawken/FrontView/rel...tag/1.9991
Replace FrontView.exe in ProgramFiles with this version.

Update:
Just install New Version Below which includes all these changes and a bit more.

But Do:
Do turn on TRACE and DEBUG logging and post log.
