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, with 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, so the higher the pixel count, the higher the resolution. The "K" in 4K stands for Kilo (1000), meaning a TV that has achieved a horizonal resolution of about 4,000 pixels.

A large screen size TV is used to show what 4K resolution is in terms of total pixels, which is 3840 pixels horizontally multiplied by 2160 pixels vertically.

How good is the picture quality?

4K TVs have four times more pixels than traditional Full HD (1920 x 1080) TVs. Even on TV screens of the same size, the 4K TV picture quality ends up being more vivid and detailed thanks to the greater pixel density. This difference is especially obvious in large screen size TVs. For example, if you compare the quality of a traditional 65" Full HD TV to a 65" 4K UHD TV, you'll notice a difference in the pixels that make up the screen. 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 experience without restrictions on viewing distance and watch from up close without noticing the individual pixels.

Enjoy all your content
in 4K quality

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, 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 4K-like quality.

The city night view displayed on the TV screen is divided with 4K resolution and Full HD resolution picture quality. The 4K picture quality on the right side brings a more realistic image than the other side showing Full HD picture quality.

Difference Between 4K and 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.
