If you’re into your gadgets and always aim to keep up to date with the latest technology, you’ve no doubt come across the new emerging development of 4k TVs.

If you’re not-so tech-savvy, but are after a new TV and have heard this phrase but aren’t sure what it means, we’re here to help. We’ve come up with a bit of guide to help you understand what a 4k TV is and why it’s so exciting.

4k tv

What does it actually mean?

4K TV, also known as ultra-high-definition TV (ultra HD), is the next generation of television picture quality, displaying four times the detail of HD.4K Ultra HD is a resolution of 3840 pixels x 2160 lines. 4K UHD has twice the horizontal and vertical resolution of the 1080p Full HD format, with 4 times the pixels overall.

4K can also support a higher frame rate – up to 120 frames per second. The increased frame rate means that fast action scenes and moving water will appear much smoother. 1080P HD currently only supports up to 60 frames per second.

What are the pros and cons of 4k?

As with any new major development, there have been proven pros and cons of it from a number of different sources.


  • It’s the most current, advanced and up-to-date TV picture technology.
  • It provides a super sharp picture that is above all the rest.
  • They’re available from the biggest (and best) brands, including Samsung, Sony, LG and Panasonic.
  • There are no 4K TV channels to watch as of yet, but the TVs can take standard and high-definition TV, as well as Blu-ray films, and boost them to near 4K picture quality.
  • The picture is so good it rivals 3D quality, but you won’t even need the glasses to enjoy 3D movies and shows!


  • As it’s such a new concept and product, they’re really expensive at the moment, especially the first ones that are available.
  • Launching a 4K TV channel is possible, but as it costs around five times more than launching an HD channel, broadcasters may worry that not enough people can watch it yet.
