It also seems to be a software problem, since it works under Windows/Bootcamp (!) It looks like incompatibility between MacOS and this iiyama model (or I guess this DisplayPort version). Is it possible that my external display isn't compatible ? I've tested the cable, adapter and screen with another computer and everything works fine.

Force detect the display (the display goes out of sleeping mode, but then wont be detected).

Switching off and unplugged the display, plugged it back in etc.

Reseting the SMC and NVRAM and tried all 4 usb slots.

When I plug it in, the external display goes out of sleeping mode, but the MBP does not detect it and after a couple of seconds, the display displays a "no input detected" message and goes back to sleep.

External display : iiyama prolite b2783QSU.

Cable Matters Adaptater USB C to DisplayPort your current ig-platform-id is 0x3E9B0007 (CFL framebuffer mis-match with your IGPU but it work), it use bus-id 0x05 (port 5), 0x04 (port 6), 0x06 (port7), 0x00 (port 0 not activated), all connector type are DP and usually WEG will auto apply DP to HDMI patches, means that your HDMI probably linked to 0x00 (port.

No worries, it’s easy to do and the back of your TV probably has a dual RCA-style “audio in” jack you can use with a simple audio splitter from Radio Shack or similar to accomplish the same goal.I'm trying to connect a MacBook Pro 16" to my external display through DisplayPort with these devices :

Once I’ve switched the output audio, it should automatically be feeding audio to the TV so a quick test with the movie trailer should work great, audio and video both. It just means that I’ll have to adjust the volume on the TV itself rather than on the computer. “The selected device has no output controls”. I click on “Samsung” and get an interesting warning message at the bottom: See the second choice down, however? That’s what we want, for the Samsung HDTV we’ve plugged into: The default audio output is “Internal Speakers”, so it’s no surprise that while we’re seeing the video on the TV, the audio is still being piped out of my MacBook Pro speakers. To switch it, choose System Preferences off the Apple menu, then look for “Sound”: It all looks good, but the audio is coming out of my computer even as the video is being fed to the HDTV. I’ll start with a frame from a movie trailer (can you identify it for two points?) Let’s start there and then if it’s still not working, I’ll show you what to look for in your hardware configuration app to check your HDMI / Display Port capabilities. Switch that and *poof* you’re good to go! It’s about mid-2008 that the Apple hardware started to support HDMI audio, based on the research I’ve done, and there’s a pretty easy way to find out if your particular device works or not.īefore we do that, however, odds are that the problem is much simpler: your Mac probably just isn’t configured to use the HDMI adapter as the audio output for your system when you have things plugged in. How old is your MacBook? If you have one that’s too old, it turns out that it might not be able to push audio through your DisplayPort, in which case the HDMI adapter isn’t going to be able to perform miracles, sorry to say.
