When I select an image on the library module and then click on the develop module; my picture doesn't show but however it only shows a blue screen and the picture on the left side on a little box. How can I change it to where I can see my picture fully on the develop module?
You need to log into your Creative Cloud account. If you have the Creative Cloud desktop application installed you can log in with it.
Disable the graphics option in Lightroom Preferences.
Uncheck the option in: Preferences > Performance > Use Graphics Processor.
