External monitor 4k HDR 60hz with my 14" MBP M1 PRO

[calheira]

I was trying watch 4k Dolby Vision videos from my iPhone 13 PM on tv LG OLED CX. When I thy on MBP M1 PRO the image quality was poor, using HDMI port from MBP. Apple sr adviser answered that I can only watch 4K HDR with a usb c adaptor.

I called 3 times and all the answers was the same.

I am so disappointed because air play doesn't support 4k Dolby Vision content either.

The built in HDMI port is 2.0. Dolby Vision requires HDMI 2.1 and a high speed HDMI cable.

I think something like this would work.

As you can see, I was expecting Macbook HDMI 2.0 run Dolby Vision content.

by the way, this adapter was sent by apple support as a solution for my problem, a HDMI 2.0 adapter.

edit. now I got it, HDMI 2.0 run 4k Dolby Vision 30hz, 4k Dolby Vision 60hz need HDMI 2.1.
