Hi, Thanks for the review. After trying a lot of 4k TV's, eventually I gave up on them. All seem to have some kind of a jello effect on the screen, and/or yellow cloud, some kind of a blob that comes and goes, when the incoming signal is less than 4k(480, 720, 1080), no matter what the settings are. Only the 1080p TV's show a clean picture. I've shortened my list of options down to these: Sony W650D and Samsung K6250. Both 40". Don't like the LG or Vizio or TCL or Hisense or any other "no name" brand. Primarily watching OTA shows, movies and news and the incoming signal is 480i, 720p and 1080i. We also watch some shows and movies on Hulu and news by streaming in 1080p. All of that always in a dark room directly in front of the TV set, about 7-8' away. Not interested in any games, smart features or anything else. Which one would be better ? Thank you.
