So here's where most folk get "sold" on 4K UHD. They are shown the screen up close and you can see it. Move back to your usual viewing distance and most can't see it.
Also, 720P Plasma beat or matched a 4K UHD LED at https://www.cnet.com/news/budget-tv-resolution-rumble-720p-plasma-vs-4k-led-lcd/
If you are at 1080p, you can wait.
DirecTV contract customer who does not utilize streaming.
We currently own an amazing LG OLED 55EG9100 HDTV. I'm tempted to move to a LG OLED 4K Ultra HD OLED65C7P but common sense is telling me that plentiful non-streaming 4K content is not going to be available for quite some time. All of our AV supports the max of 1080p.
Your thoughts please.
