My 65CX arrived yesterday, only had an hour to play around with it. It's quite an upgrade from my almost 5 year old 50" Sony LED!
Picture is stunning with 4k feed and impressed with the sound for a TV. However, I had a quick 10 minute blast on the PS4 (not pro) and yes I know it's only 1080p but it looked awful. Washed out colours and jaggies were very noticeable. It was only World of Warships so maybe that particular game doesn't upscale well but it's a huge downgrade from the Sony LED so must be something wrong there?
Found the menu's confusing at first but soon got the hang of it, not sure I like the wand though. Oh and the 65" is absolutely huge! It's too big for my man cave, so might end up putting it in the living room to replace the old faithful Panasonic Plasma, finally a TV that can beat it for inky blacks!
