As title says, firmware 1506 broken HDMI 2.1 functionality for probably all users. In my case it simply doesnt work, for others it either works half (sends limited video) or not at all. On Xbox you cant enable higher refresh rates, thats if you actually manage to make it work.
Other non 2.1 ports work reasonably okay. It sometimes go into crazy blinking if you change sources from TV to something else, but flipping to picture/frame mode and back solves that.
Samsung doesnt seem to care about it or plan to fix it. But they are according to quite a few sources aware of this problem.
Update: Weโve updated the results to more accurately reflect the blenderโs performance. The score for Fibrous Ingredients (Small Batches)processing changed from 10 to 8.5, and the score for Fibrous Ingredients (Full Capacity)processing changed from 10 to 9.5 because of the blending time. The preparation score for Crushed Icechanged from 10 to 9.0 because you must pulse manually. The preparation score for Nut Butter changed from 9.0 to 7.0 because of the blending time and the need to use the tamper.
