What is 4K Ultra HD TV?
There are two new types of TV screens starting to enter the consumer marketplace. Both, for now, are high end, costly, but like LCD's were when they first came, prices dropped over the years. So, if cannot afford either, just wait.
One new TV is the curved screen to simulate the IMAX experience, I guess. Of the two new TV's, I think this will ultimately fail because the curved screen is best effective and awesome when the viewer is sitting in the center of it and close enough to fill up the field of vision. It is fairly spectacular, but, if you have a group watching and further back out of the field of vision, it is no better that a flat screen and the curved screen is actually noticed. Watching the TV from a side angle is not enjoyable.
4K Ultra TV
The 4K Ultra will probably be the successor to the LCD as time goes on. The viewer can easily see the dramatic clarity of the picture. Why? Unlike the gimmick of a curved TV, the 4K nearly triples the number of pixels that make up all TV pictures.The more pictures, the more detail and clarity.For instance, HD TV has 1920 x 1080 pixels. The 4K has a whopping 3840 x 2160 pixels! This totals to 8.3 million pixels. The TV, because the pixels are smaller on it, allowed viewers to sit closer to it without noticing them. The resolution is about four times of current HD TV.
The 4K TV's today are costly. A 50 inch. screen can cost $1500. A HD TV is half that price. But is Ultra TV a gimmick? No, if you sit within 3-4 feet of your screen, which nobody ever does. In fact, as Consumers reports indicated, most sit at least 6 to 10 feet from their big screens that are greater than 50". At that range, the human eye cannot discern the differences between HD and Ultra TVs. Not all movies and broadcasts convert from HD to Ultra and when you see a show in the showroom, you probably will not get this when you get the TV at home. Another issue it needs to deal with is motion resolution.
So, if you cannot wait for the Ultra TV and plan to buy one, you need to by one in the 70-90" range for the greatest benefit. Buying one less than that is just wasting money. But, most experts suggest to wait a year or two so issues are resolved and screen prices drop. Yet, the bottom line remains- as a viewer, you will probably not really notice the picture quality difference sitting 6-10 ft. away.
