Screen Resolution Problem

I have KODI 16.1 Windows 7 SP1 32 gig of ram.
I have Kodi running in 1080p full screen,I have my PC games launching from within Kodi using Advanced Launcher.My problem is when I launch a game and it is 720p when I exit that game windows switches back to 1080p but Kodi is still zoomed in,it’s resolution is still 1080 but it has to be restarted because of the zoom effect windows does to it from being in 720….thank you for your time….
