HAHAHA if you want the biggest ? with the best picture quality, color, and doesn't care about the budget?
Here you go:
•2k x 4k res, 4x the res of 1080p
•50% less power use via double luminance efficiency — big deal on a set this big.
• Home hearth UI lets you to add a fireplace, windows, and wallpaper, etc. Your TV is now your wall, which is cool and sad.
• You can get video calls and use some apps (assuming you'd have a camera or something).
All i can say is.. HOLY CRAP!
