The display size on my system is not retained. In Control Panel - Display the display is set to Smaller - 100% [default] but this is not retained. Essentially at every boot the display size defaults/resets to 125% though Control Panel - Display shows the setting as Smaller - 100%. If I do a Shutdown - Restart the display size will set to 100%. Whatever the actual display size Control Panel - Display shows Smaller - 100% as selected. I did try Medium one time as my eyesight is not great but didn't like it so I went back to Smaller. This problem began occurring some weeks after going back to Smaller.
