New MacBook Pro Models Include HDMI 2.0 Port Instead of HDMI 2.1

I'm rarely ever the one to give Apple any credit for doing the right thing. In this case though I can imagine that it was a good technical decision. Being still more of a business machine than gaming a 4k 60Hz seems reasonable for now. If necessary Thunderbolt/USB-C ports can be used. What it means though is that the bandwidth/power usage of the HDMI port is better bounded.

2.0 is also limited to 4:2:0 chroma subsampling for 4k60 HDR displays and it's not really a question of power. Though like you say the option of the other ports makes this not a big deal overall, if still a little disappointing.

I didn't realize that all the stated resolution/refresh rates weren't achievable using RGB data mode.

Also worth noting that last I checked macOS defaults to YPbPr on non-Apple branded displays. (Some) LG models may also work in RGB mode out of the box as they were sold as Pro gear in Apple stores. Searching for "RGB EDID patch .rb macOS" can find solutions.

I posted about this a few days ago from Ars but it never gained traction. Not sure how this one is on the second page.

Anyway I’ve had issues with DVI support 1.2 support and recent versions of MacOS. A monitor that previously worked for a year stopped working until I downgraded it to a lower DVI version.

Maybe someone has had a similar experience with HDMI and MacOS limitations.

I have a similar issue with a M1 MacBook Air.

My 1440p 144 Hz monitor works fine on my Intel MacBook Pro via USB C, but the M1 MacBook can’t do more than 60fps on the same connection.

Have not found much info about it at the time either.

It's definitely a conspiracy! /s

My 2015 MBP will output 4K/60Hz through its native HDMI port as well. ;)

That said I understand the concessions here, the comments indicate the HDMI port is likely sharing a lane with the SD card reader. You can still get higher resolutions and refresh via the other ports. Although I won't be buying one of these machines for a long time, it's still nice to see the ports make a return.
