What is 4K?

Ultra High Definition, which was earlier known as 4K, has the potential of making people forget all about HDTVs they currently see all around them and can change the electronics industry entirely. Everything you need to know about 4K or Ultra HD is in this article.

What is Ultra High Definition/4K?

Ultra High Definition is the next step manufacturers are ready to take in the HDTV era. We looked at this matter briefly a few days ago when discussing possible things we’re hoping to see at the next CES, but here, we’re going in a little deeper. The CEA, Consumer Electronics Association, defines a TV of this nature to display 8 million active pixels on the screen while featuring a lower resolution boundary of 3,480 by 2,160, at least. However, currently it’s difficult and more complicated than we initially though because there’s no such standard of such technology even though there are many varieties of content available in the market, but this depends primarily on the theater and what movie they’re showing.

At first, this HD technology was referred to as 4K, but the CEA changed the name of this tech to Ultra HD.

How Is It Different?

So in simple terms, ultra HD will offer you the standard 1080p resolution offered by HDTVs but four times over. But don’t worry about it because content delivered by the screen will be compressed so it can be compressed for home use because if it wasn’t compressed, it would require a large amount of space; a 2 hour movie playing at 30 frames per second would require you to have 55TB of space available for storage. YIKES! Ultra HD, on its own, takes 1GB of storage just for one second of playback, which means you need faster hard drives and faster than usual internet connectivity.

Many people have difficulties of seeing the difference between 720p and 1080p sometimes especially on a desktop monitor though. However, the difference can be easily seen on a larger monitor or screen, perhaps a 50-inch TV.

When Can You Get It?

These Ultra HDTVs are close to hitting the market but the prices will be extremely high. At the beginning of September, Toshiba and Sony both unveiled their 84inch Ultra HDTVs. LG then followed up on in later October. Prices are expected to hover in between $20,000 and $25,000, and that clearly means not many of us will be making an investment in this technology any time soon.

Do We Really Need It?

We think the 4K technology will end up like the 3D fad. It will be considered to be something mainstream in the next 5 or more years, taken up by early adopters and enthusiasts, but the ordinary consumer will never buy something like this until and unless the price comes down. If you’re enthusiastic about 3D movies etc, than this is something that will offer you more realism
