What is 4K TV?

What is 4K TV?

Remember when you saw your first HDTV? Its stunning image was much sharper than anything you had ever seen before on a standard TV. It looked so much better because of its increased resolution; a high-definition television has about six times more pixels than a standard TV, which means fewer jagged images. The result is a sharper image that looks smoother, more realistic and more detailed.

 

Well, 4K TV (also called Ultra HD) is the next step in dazzling TV displays that makes another large jump forward in jaw-dropping screen resolution. A 4K display has about four times more pixels than 1080p HDTV. To put that in perspective: a standard TV has a resolution of 720x480 with about 365,000 pixels; an HDTV's resolution is 1920x1080 with about 2 million pixels; and a 4K HDTV's resolution is 3840x2160 with about 8 million pixels. What this means is that all flat panel TVs utilizing 4K HD technology will have a stunning, pin-sharp display.

 

The Benefits of 4K HD

One of the common criticisms of 4K TVs is that you may not be able to even notice the increased resolution. Depending on your living room situation, this may or may not be true. There are several circumstances, however, in which 4K HD can make a huge improvement in your viewing experience.

 

The vastly increased resolution will be more noticeable on bigger TVs, whether it's a high-end Samsung or a more reasonably priced Seiki. As TVs come out in larger sizes, a higher screen resolution is needed to maintain the same level of sharpness and clarity. A 4K display is also a great choice for TVs with passive 3D technology, whose technology cuts the resolution in half in order to achieve a 3D effect; on a normal HDTV, this can cause the image to look fuzzy. A passive 3D TV with 4K HD technology, however, will have a crystal-clear picture even after the resolution is cut in half. A 4K display allows you to sit closer to the screen without seeing pixilation. This means you can sit close enough that the screen fills your entire field of vision, creating an immersive experience. It's also an important benefit for those with a small living room. 

 

In the meantime, however, some 4K TVs contain an internal upscaler that will improve the resolution of even non-4K content. In other words, if you watch an HD movie on a 4K display, the picture will be even better than standard 1080p HD. Many movies are also being remastered in 4K, which means you can watch the classics in greater detail than ever before.

 

It's only a matter of time before this technology becomes mainstream. Years from now, all our TVs will give us the jaw-dropping clarity of 4K HD. Until then, however, it's up to you to decide when to make the upgrade to a 4K display. When that time comes, shop Kmart for a great selection at low prices. 

 

Finding Content for 4K displays

What will you watch on your 4K TV? It will take some time before 4K content is widely available. This is true with any new technology. New 4K movies and TV shows are coming out all the time, however. Before long, you'll be able to watch 4K movies from Blu-ray players and streaming online content providers like Netflix, YouTube and Hulu Plus. There may eventually be 4K TV broadcasts.

A mattress can still be structurally sound while still having other problems that keep you from falling asleep. Dust buildup, for example, is a common problem with older mattresses. It's definitely not fun to think about, but skin particles, pet hair, dander, insect parts and dust mites can all add up to create an unhealthy sleeping environment, especially for those with breathing problems. Consider replacing your mattress if you're noticing that coughing and sneezing is preventing you from getting good sleep, or that you're waking up with a sore throat and stuffy nose.
