If you absolutely, positively have to have the BIGGEST TV, then it will be a 146" diagonal Samsung!

"As a tiled display, The Wall MicroLED 4K TV can theoretically be just about any size. But at CES 2018, Samsung is talking about a size of 146″ (diagonal) with an aspect ratio of 16:9. And as the name indicates, it will have 4K/UHD resolution (3840×2160)."
