4K TVs with clearer and smarter features have become a preferred choice among buyers. Nowadays, more 4K movies and shows are available in ultra-high definition.

However, you must be doubting the differences between a 4K TV and a classic 2K (Full HD) TV. Do you really need to upgrade to 4K?

Thus, this blog contains the knowledge you need to know about a 4k TV.

What does the word '4K TV' means?

When we talk about 4K TV, names like Ultra HD, UHD, and 4K Ultra HD are often being bandied. However, they all refer to the same thing. 4K TVs are televisions with 3,840 x 2,160 pixels, which have more than 8m pixels in total. 4K TV's pixels is four times the number in Full HD (1,920 x 1,080).

A 4K TV works more effectively on a larger screen. The resolution and the latest picture processing technology make more precise and astounding 4K images. The result is a stunning clarity that makes all images come to life.

What are the Differences between 4K and 2K (Full HD) TV?

Resolutions and Pixels

The most important difference between a 2K (Full HD) TV and a 4K TV is that the latter has a higher resolution that provides sharper images.

Meanwhile, the resolution is differed by the pixel numbers, the smallest digital graphic unit displayed on a device. These pixels are organized into rows and columns.

The resolution will define how many pixels there are in each row (width) and each column (height).

Differences between a 2K and 4K TV


Pixels of 2K and 4K TVs:

  • 2K or Full HD: 1920 x 1080
  • 4K or Ultra HD (UHD): 3840 x 2160

We usually refer to a 2K resolution as 1080p which sounds more familiar.

So, a Full HD TV with a 1920 x 1080 resolution means that it displays 1920 pixels per line and 1080 per column. Meanwhile, a 4K TV displays 3840 pixels per line and 2160 per column.

To put it simply, the more pixels mean the better display quality for the viewing experience.


You can straightly spot the difference of color displayed when you stand in front of both 4K and 1080p TVs.

4K TVs can achieve a wider color gamut, offering a more extensive palette of colors than a 1080p TV.

A 4K TV screen looks stunning as it can display images with a more accurate depth with exceptional contrast between light and dark than a Full HD TV. With this feature, 4K TVs can display lifelike images nearly identical to what you see in real life.

Besides, 4K is now the preferred resolution to look for HDR or Ultra HD (UHD) features.


Smaller screen devices such as laptops and computer monitors are widely available in 1080p TVs.

We can say that Full HD TV resolutions are more suitable on smaller screen devices. This is because screens at 40″ and below are not large enough for 4K to look noticeably clearer or sharper.

Besides, a Full HD TV and 4K TVs also differed in their availability and content.

Almost all streaming platforms support Full HD TV content in the past, but major streaming platforms like Netflix, Amazon Prime, and YouTube have already joined the 4K team now.

Benefits of a SHARP 4K TV

  • Picture quality – Resolution

A 4K display reveals so much more nuances and detail. You will be more like "gazing through a window" instead of watching a TV due to their realistic image quality displayed.

Also, the higher pixel density of a 4K TV also enables you to get much closer without the grid-like structure of the image itself becoming visible –this means you can comfortably watch a much larger screen from the same seating position as your current Full HD panel.

  • Upconvert to 4K quality

Although we are now firmly in the modern era, we are not all watching 4K content. Full HD images on a 4K panel will not look better, just bigger, however, unless some clever upscaling is used.

But now, with 4K TVs' Upconverter technology, it can convert your SD or HD videos into 4K resolution, producing superior image quality. The upscaling process ensures that the image or video fills the screen's 4K resolution.
