Sony's 56-inch OLED UHDTV may be the brightest, sharpest TV the company has ever made. That is, if it's ever made, since we're pretty sure that the prototype shown at CES is one of only a few in existence.
Hisense's 110-in XT900 is too big for your home
More UHDTVs from Sony, LG, and even Westinghouse
Unlike the OLED model, Sony's Bravia UHDTVs are already available. The 84-inch model currently sells for about $25,000, and it's set to be joined later this year by 55 and 65-inch versions, which Sony says will be available "at a cost that is right around that of a premium HDTV."
Samsung's 85-inch S9 is a sort of "goes to 11" model, since it's an inch larger than Sony's flagship UHDTV model. However, it's not yet available, and two larger versions, including a Hisense-tying 110-inch model, were mentioned at CES, but weren't on display in Vegas.
Vizio is known as a budget TV brand, and if the company keeps its promise to "bring the expensive new technology to mainstream consumers," we may see some more affordable 4K sets from the company later this year -- though, of course, no pricing or availability info was provided at CES.
LG joins Sony as one of the few companies with a UHDTV model that you can actually buy today. The 84-inch model is available for just $17,000 -- and that includes free two-day shipping.
Like Hisense, Westinghouse has a 110-inch 4K prototype to show off, and the company promises "more affordable" 50, 55 and 65-inch models that will provide "amazing clarity." Unfortunately, as of CES, Westinghouse's lineup didn't have a ship date, pricing, or even model names or numbers.
Not all of the 4K displays at CES were on TVs. Sharp showed off its IGZO Professional 32-inch monitors, which should be out in February. Sharp also has a touchscreen version of the monitor, which should ship later this year.
Speaking of 4K displays that aren't on TVs, the big surprise of CES had to be Panasonic's unnamed 20-inch 4K tablet. Panasonic isn't saying much about the Windows 8 slate, other than expressing confidence that it will someday be available to well-heeled professionals.
