Anyone have current insights into 4k tvs? I'm thinking of replacing 55" 1080p with a 65" 4k tv. We moved about 3 years ago and 55" was the right size for the old house, but 65" would provide the same viewing angle at the new house. Would like to stay under $2k. I don't really care about sound, as I would always be using the home theatre setup and not any built in speakers.
