Kodi is stretched off the screen.

Frequently, when I turn my system back on after a period of inactivity Kodi resolution is stretched such that a portion of Kodi can’t be seen. I recall having this problem, and finding a fix for it a long time ago. It started again doing a fresh install of Windows and Kodi. I’m using Windows 10 and Kodi Krypton.

Thanks for any help!
