Step 1: Right-click an empty area on the desktop and select Personalize.
Step 2: On the personalized page, select "Desktop Background".
Step 3: On the "Background Settings" page, check the picture for which you want to set the background (if there is a picture, you don't need to set the switching time; If there are multiple pictures, just set the switching time), click "OK" and there will be no "black screen phenomenon".
