Okay so to be clear, has this problem come from the latest 05.80.15 firmware, or did it happen from any of the earlier firmware updates?
And yes definitely, if it is a known problem then LG needs to fix it, if they don't do that one should be entitled to a refund or replacement, at least in the EU, don't know if that works in real life though, I would really hope so.
I don't use Apple TV, i only use the TV with a set-top box with 4K capabilities to watch cable TV, and i´m in a 50 Hz country as well. I wonder if it would affect me if watching 4K channels through my set-top box?
Is it all the colors equally washed out, or does it only affect some particular colors, I guess it must be all colors, or?
