What does 4K mean?
A 4K TV is a TV set with 4K resolution. That means the TV has 3,840 horizontal pixels and 2,160 vertical pixels for a total of about 8.3 million pixels. On TV product specifications, resolutions are usually shown as "3840 x 2160" for 4K TVs.
Resolution is a term that tells you just how densely these tiny dots, the pixels, are put together on the display. Individual pixels collect together to make up the image you see on the screen and therefore the higher the pixel count the higher the resolution. The "K" in 4K stands for Kilo (1000), meaning a TV that has achieved a horizontal resolution of about 4,000 pixels.
How good is the quality?
4K TVs have four times more pixels than traditional Full HD (1920 x 1080) TVs. Even on TV screens of the same size as a 4K TV, the picture quality ends up being more detailed thanks to the greater pixel density. This difference is more obvious in big screen TVs. For high-resolution TVs, the pixels are smaller than in a lower-resolution TV of the same size, so you can enjoy a more immersive, clear and detailed viewing experience.
What 4K content is available?
When 4K TVs were first introduced, there was not much 4K content to watch. This caused some consumers to hesitate purchasing the TVs. Now there's so much 4K content available that it's no longer an issue.
Currently, there are various forms of 4K content from 4K Satellite Providers, 4K streaming services, 4K Blu-ray players and discs to even 4K gaming as well as 4K filming on smartphones. There are approximately 80 channels worldwide that broadcast in 4K (according to Wikipedia), and VoD services such as Netflix, Amazon Prime, Stan, Apple TV+ and Disney+ also offer a wide range of contents such as 4K movies and TV series. Plus, if you have a 4K Blu-ray player you can easily purchase and enjoy 4K videos from many of the electronic retailers in Australia or via purchasing online.
Recently, a lot of people enjoy filming videos using 4K cameras or smartphones with 4K cameras built in and share that content with other users through video sharing platforms such as YouTube and Vimeo. So, feel free to explore whatever catches your interest.

Make your non-4K content look better than ever before.
It would be great if all recorded content were filmed in 4K, but there's still a lot of lower resolution content out there in comparison to 4K content. However, thankfully this is not a concern because of upscaling.
So what is 4K upscaling and what can it do for you?
When you watch lower-quality FHD content on a 4K TV, upscaling is the technology that increases its resolution, converts, and optimises it to fit the display panel of a 4K TV. In other words, it doesn't just stretch the image — it upgrades it for the 4K display. Upscaling automatically analyses resolution to reduce noise, improve details and provide optimum contrast and colour so that you can view this content in better quality than ever before.
What is 4K? What is UHD?
To put it simply, UHD stands for Ultra High Definition and 4K Resolution is a type of UHD resolution.
Different brands use various expressions to say the same thing, such as Ultra HD, 4K TV, Ultra High Definition TV and 4K UHD TV. As time passed, the TV industry found the phrase "4K" easier and more intuitive for consumers and began to use it more and more. Today most manufacturers and distributors now use the term 4K TV or 4K UHD TV. Recently, another type of UHD TV has begun to show up on the market: the 8K TV.
Get on board
High resolution TVs are something to consider when purchasing long-term replacement products like TVs. If you're going to buy a new TV, then do yourself a favour and choose at least a 4K TV.
