I have a Samsung Samsung MU9000 curved TV and I was wondering if it has been upgraded to use an hdmi 2.1 cable or if the the one connect box can be upgraded to use an hdmi 2.1 cable.
Hi @Tim9 Unfortunately as far as I am aware a 2017 set would not be hardware compatible. Some 2019 models will be elegible for complimentary upgrade of a board in the set’s One Connect Box (installed professionally) to accommodate 8K HFR over HDMI 2.1, Samsung stated a few years ago.

There was a esrc firmware update for 2019 models earlier https://eu.community.samsung.com/t5/tv/earc-is-coming/m-p/1403831
