Just an update in case anyone is interested. I picked up the tv on Friday and I love it so far. First tv I've purchased since 07 and I feel like I made a solid purchase. The cast is actually pretty cool. I don't use the tablet hardly at all except to tweak my settings. Otherwise it's just another tablet that my kid messes around with. I haven't had time to really sit down and enjoy the display, but I was able to mess around casting some youtube vids in 4k and it looked awesome! I also messed around with casting some compressed movies off my plex server. I did run into an issue with audio when casting. We have an ac unit in this room and it's pretty loud so I'm running sound out of my receiver and surround. When I cast, the video would switch, but I'd get audio from the cast coming out of the tv and audio coming from the receiver at the same time. I was able to fix it setting my receiver to audio return channel(?) (ARC). Now I'm getting delayed responses adjusting volume from my remote when casting, but at least I can get the audio coming out correctly.
