Hello
I have a macbook pro early 2020
and just today, I bought a new adapter for HDMI
connected it to my external monitor, the background is blue
plain blue, it wont have the background I have in my laptop
although everything els is fine
why is that?
btw
I had another adapter before, but worked fine
MacBook Pro 13″, macOS 11.1
Hi Robie3x,
Thank you for using Apple Support Communities. Sounds like you are not seeing your Mac's wallpaper displayed on your external monitor when connected using the HDMI adapter, do we have that right? Do you have a Desktop wallpaper set up for your display background? You can set it by going to the Apple Menu ( ) > System Preferences > Desktop & Screen Saver. There you should get two windows and be able to select the background you want displayed on each screen including choosing the same background.
Change the desktop picture (background) on your Mac
Hope that helps!
External monitor blue background?
