MacBook Pro display only black screen on direct HDMI connection Hi MacBook Pro 14 M2 with Mac OS 15.3.1 At some point this year, when I connected the direct HDMI plugin to the projector it only shows black screen. The projector shows it is connected, but not shown on Mac' display setting. At the same time I was able to connect and display correctly through the direct HDMI plugin with a "VGA to HDMI" converter. Not able to locate the "detect display" anymore, so not sure what settings that i can change to test. Or if there's anyway to reinstall any driver or so?

MacBook Pro detects projector but projector says “no signal” I know this has been asked before but nothing seems to work. I connect my 2020 MacBook Pro to a projector (different brands), the computer recognizes it, changes resolution, but the projector says “no signal”. It’s independent of the adapter (Apple, third party). Any tips? thanks Ed

Problem connecting Projectors to Apple Silicon laptops using the HDMI port This seems to be a common (older) problem, but I am trying to connect a Benq projector to the HDMI port on my M4 Macbook Pro (which always worked fine on my pre Apple Silicon macbooks) but the M4 doesn't see it as an available display. Is there a solution to this problem? I have a number of projectors that I can't use on the new Macbook, arrggh! I'm using Sequoia 15.6.1
