When the new MacBook Pro came out this year, everyone was puzzled as to why the newly included HDMI port was only 2.0.
Well it turns out they lied. It’s 2.1 after all! \s
Jokes aside, it’s actually only 2.0 because internally they transmit a DisplayPort video signal and convert it to HDMI using an MCDP2900 chip[0], which is the same chip usually seen inside USB-C hubs.
So the new MacBook basically got rid of the HDMI dongle by integrating it inside the laptop.
This also breaks DDC/CI on that port and now I get a ton of support emails for Lunar (https://lunar.fyi) because people can’t control their monitor brightness/volume and think that the app is broken.
