If you just have to have the biggest, baddest, most-Ultra of the Ultra High Def TVs, you have a very large TV room, and similar budget, then this is the TV for you.
First announced at CES in January, Samsung's UN105S9W features a curved screen with a 21:9 aspect ratio (instead of the typical 16:9 of most HD TVs), and a resolution of 5120 x 2160. The wider than normal aspect ration will appeal to movie buffs, who can watch many Blue-ray movies without black stripes above and below the image. The flip side is that normal TV programs, shot in 16:9 format, will have black bars on the sides, but with a screen this large that's not likely to be a significant issue. The TV also offers Samsung's "Quad Screen Multi-Link" feature, which allows you to divide the screen into 4 sections, allowing you to watch live TV and a DVD, stream video content, access the web, all at the same time. This might require a whole new definition of "Four Eyes," however.
About that very large budget: As you might expect, all this technology, and a screen this large, doesn't come cheap. With a price tag of $119,999.99, the market for this set is going to be limited, to say the least. For the price of this TV, you could buy two of Samsung's $40,000, 85 inch UHD TVs, and throw in a 65 inch 1080P set for the bedroom. With enough left over to pay a lifetime of cable bills and DVD rentals.
If it helps, that price includes a visit from a Samsung technician who will set up the TV for you, optimize it for your viewing room, and explain how to use its many features.
