I upgraded my HP Stream 7 tablet from v1809 to v1909 and the display wants to be upside down. I have to lock the rotation in Landscape or Portrait mode to keep it right side up. If I don't lock the rotation it goes into the (flipped) mode.
This did not happen with previous versions of Windows 10 or with the version of Windows that came on it. I had Device Manager check for a new version of the display driver but it did not find any.
Any ideas on how to fix this so I can leave the rotation unlocked like it's supposed to be?
