Based on experience with my own 2021 43" The Frame, firmware 1506 makes HDMI 2.1 port basically useless. Same according to other users.
Any plans to fix that or does it require class action lawsuit?
Btw. in EU there is some time period given by law until manufacturer should fix broken device. In this case, HDMI 2.1 is clearly broken as of release of that firmware. In my country, fix is already 1 month late.
I can confirm that many users are having the exact same issue with firmware 1506 (me included) . Samsung, please provide an update and confirm if you're working on a patch or new firmware release.
