It shows “no HDMI signal from your device” message
I did all plug off and plug on restart steps and it didn’t fix anything at all
all connections are correct. I have just one big Dell monitor connected to my MacBook via HDMI
what should I do please to fix this ?
Hello rexhina100,
Thank you for using Apple Support Communities. Sounds like your Mac isn’t recognizing your external monitor. If so, we’d like to recommend some additional steps to help further isolate this issue. Try following the steps below:
1.) Install pending updates that might be available for your Mac. Keeping your Mac fully updated can help resolve various issues.
2.) Test a different HDMI cable. This step can isolate a possible cable issue.
3.) Test a different monitor if available.
4.) Start up in safe mode. This step can also help isolate possible software related issues.
