The Wall is a massive 292-inch television -- officially the biggest one we've ever seen at CES. This gigantic screen uses MicroLEDs, which offer both high brightness and excellent contrast. It'll be a long time till these appear in homes though -- even the more modestly sized ones can cost hundreds of thousands to install.
Speaking of motorized screens, LG has touted the rollable OLED TV for a number of years, but the company has chosen 2020 to make it a reality. For only $60,000 you can get this 65-inch 4K TV that rolls up and down with the flick of a switch. You could get one of the ones that just SIT THERE, not rolling, for $2,000.
Even though it's merely 4K, the P-Series Quantum X promises better contrast than before with 792 zones of local dimming on the biggest 85-inch size. Also it has quantum dots, which help make the colors pop, especially in HDR.
