The Latest in Television - 4K TV


From the early days of black and white TV tube sets to flat screen high-definition TVs, television technology has constantly evolved and changed over the years.

And just when you thought you’ve seen it all – here comes the newest exciting TV innovation – 4K.

What Is 4K?

Ultra HD (4K), or Ultra High Definition, is the next big step in HDTV resolution. The Consumer Electronics Association (CEA) defines an Ultra HD television as one that displays at least 8 million active pixels, with a lower resolution boundary of at least 3,840 by 2,160. There are multiple varieties of 4K digital content ranging from 3,840 by 2,160 to 4,096 by 3,112, but the 3,840 by 2,160 resolution is the most consistent number available and the standard resolution most UHD/4K HDTVs and monitors have settled on. It's a nice, even number, doubling the horizontal and vertical pixels offered by 1080p (1,920 by 1,080 pixels), the older standard for high definition.

Collectively, the format is known as 4K, and while the CEA officially changed its designation to Ultra HD (UHD for short), the 4K label has stuck and both terms are effectively interchangeable.

How Is 4K Different Than 1080p?

Depending on the variety (discussed above), 4K generally offers four times the resolution of standard 1080p HDTVs. Even so, 4K content will still be compressed for home use, as an uncompressed two-hour movie playing at 30 frames per second would require 55TB of storage just by itself. 4K video also takes a solid 1Gbps path for reliable playback (unless it's compressed in some way), which requires fast hard drives and faster-than-usual Internet and network connections.
