Im using Mojave latest version. Im using one external screen. When i zoom out any applications into one screen (external or main)then i got a black screen into remaining screen. How can i fix that. I don't get problem when i switch to another account. I tried to reset NVRAM and SCM but it seem doesn't work.
Thanks
Hey Tobivn,
Thank you for using Apple Support Communities! I understand from your post that you're having issues using an external monitor with your MacBook Pro. I'd be happy to help out.
You've done great steps so far with resetting the SMC and NVRAM. To continue , I'd like to try the steps here:
Use external monitors with your Mac - Apple Support
Let us know how that goes.
