Ultra HD has been around for a couple of years now, but prices have now dropped to the point that acquiring an Ultra HD set can be a serious consideration for folks in the market for a new TV, particularly early-adopters. TV makers hope that the next Big Thing in video will be Ultra HD, or as it is widely (and imprecisely) called, 4K. They also hope that Ultra HD has the legs that home 3D (now in its, “Hello, I must be going” phase) lacked.
Ultra HD can be much more than simply 4K resolution (more precisely, 3840 x 2160 in the consumer arena4K in the pro world , including digital cinema projection, is 4096 x 2160). It also has the potential to offer a wider color gamut, an increased color bit depth, and less aggressive color subsampling. If that string of technobabble sounds intimidating, it simply means that in addition to more pixels, Ultra HD could provide a wider and richer color palette than does our current HD standard.
