There are plenty of TVs at CES — and a lot of them are impressive. But this 55-inch screen from Samsung is truly remarkable. First, there's the screen — one of the largest OLED screens ever made. That means super-bright pictures with less energy consumption. (OLED has been the Holy Grail of televisions for years.) Beyond that, two people can watch different shows at the same time — on the same set —using specialized glasses, without seeing any ghosting of the other program. Pricing and availability will be announced later this year.
