HDMI Not working on Intel 520 on Acer Aspire F 15

[Andyapple]

Ok i booted with this plist and everything works like before.

There is a good news

When I plug hdmi cable i can see finally the secondary monitor (even if i plug the cable after the boot), but the internal monitor gets black and resolution output is 1080p and not 4k.

Thanks

common issue, plug in cable after macOS has booted

also your hardware profile mentions only 1080p graphics.....

Yes I plugged it afer macOS Booted and internal screen gets black.

Yes because 1080p is the internal display resolution, i am almost sure that hdmi video can go up to 4k, let me try with windows.

What can i do to fix black screen display, audio, and 4k resolution? thanks.

At least now the secondary monitor works ahahahah.

 

[Andyapple]

Yes 4k resolution over HDMI on Windows.
