Does the USB-C Digital AV Multiport Adapter transmit 4K 60Hz signal from M1 MBP?

Question

I have a 13" 2020 M1 MacBook Pro (MBP).

I'm currently experiencing some issues with a third-party USB-C hub. I'm considering replacing it with a USB-C Digital AV Multiport Adapter. The page for the adapter, if read literally, suggests that the M1 MacBook Air (MBA) can drive 4K 60Hz video via this adapter, but the M1 MBP cannot.

Can anyone confirm that this adapter can transmit 4K 60Hz signal from an M1 MBP?

Answer 1

I just tried plugging a 4K monitor into my M1 MBP using that adapter, and it only gave me options up to 30Hz at 4K.

I also didn't see any M1 Macs listed in the 60Hz list. So I suspect that all the M1 Macs will only run at 30Hz using a 4K screen on that adapter.
