Watching a 4K TV, you'll see everything on screen in crystal-clear clarity and incredible detail. There are many improvements of a 4K TV that a Full HD TV simply cannot achieve, such as color tone, contrast, content, to name a few.

What are the main differences between a 4K TV and 2K (Full HD) TV? Is 4K TV necessary since it costs more than a Full HD TV?

To make things clearer, this blog contains the knowledge you need to know about a 4k TV.

What does the word '4K TV' means?

We often refer to a Full HD or 2K TV as 1920p, as it contains 1,920 x 1,080 pixels. However, a 4K TV is an advanced technology with four times more pixels than a Full HD, which is 3,840 x 2,160 pixels.

A 4K TV is also known as Ultra HD or UHD and works more effectively on a larger screen. You will find a 4K TV with bigger screen models, generally with 40 inches or more.

The 4K resolution and its advanced processing technology bring you stunning clarity that makes all images more life-like.

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

Resolutions and Pixels

Screen resolution is the main difference between a 4K and 2K (Full HD) TV. Meanwhile, pixels are terms used to denote the resolution of the TV screen.

A pixel is the smallest digital graphic unit displayed and represented on a device. These pixels are organized into rows and columns.

Pixels of 2K and 4K TVs:

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

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.

The greater the number of pixels a screen has, the clearer the image will become – and this means the higher resolution of the product.

In terms of the color displayed, the higher pixel numbers and resolution of a 4K TV help them outcompete the Full HD TV.

4K TVs can offer a more extensive color palette and broader color gamut than a 1080p TV.

4K TVs could supply more realistic images as the screen can display a more accurate depth with exceptional contrast—this feature leads to a more contrasting effect between light and dark than a Full HD TV.

Also, 4K is now a preferable way to look for HDR or Ultra HD (UHD) features.

Full HD TVs were once the most common type of HDTV set with a screen resolution of 1080p. Computer monitors or laptop screens are widely available in 1080p.

We can say that Full HD TV with lower resolutions is more suitable for smaller screen devices. Screens at 40″ and below are not large enough to support 4K graphics to look sharper or clearer.

Besides, we can differentiate Full HD TV and 4K TVs based on 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.

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.

Content of 4K

• Streaming services – Netflix, Amazon Prime Video and YouTube

We can see that many industry leaders are making the 4K switch now. More famous platforms such as Netflix, Amazon Prime Video, YouTube and many more content are available in 4K resolutions, and more platforms are expected to join the team soon.

If you want the best image, video, and audio quality, you need to watch them in 4K resolutions. Streamed 4K movies can bring you to the next level of watching experience. Also, the movie is sharper in fine details, has fewer distracting artifacts, and has a better overall image.

On the audio side, even streaming content uses compressed audio formats, but in 4K, it will deliver to your lossless audio for enhanced clarity.
