Does 4k Video Look Better on a 1080p Screen? (It Does)

It seems like technology is emerging faster than we can keep up with. In the audiovisual world, this is definitely the case, as the quality of the video is ever-increasing, but do we really need to throw out our old televisions, just to get the best quality? Or can we keep our 1080p screen and still play 4k videos on it, without losing quality?

4k video looks better on a 1080p screen, better than 1080p videos do. This is due to the amount of pixels that each type of video and screen has. The more pixels in a video and the more pixels available in a screen, the clearer a video will look, making 4k video have the best quality on a 4k screen.

Throughout this article, you will learn all about the differences between 1080p and 4k. You will also learn why 4k video looks superior on a 1080p screen, but why you should switch to a 4k screen. We will also provide the ten best 4k screens you can buy right now.

What Is the Difference Between 1080p and 4K?

Before we continue, let’s make sure the difference between 1080p and 4k is known.

1080p first appeared in 2007. It is the next step up after 720p resolution screens. It is also known as “full HD, or full high definition.” It consists of 1920 pixels horizontally and 1080 pixels vertically. The picture aspect ratio for 1080p is usually 16:9, meaning the image has a width of 16 units and a height of 9 units. 

The “p” in 1080p stands for progressive scan, not pixels, as sometimes thought. Progressive scan is the way that an image is projected onto the screen in sequential order from top to bottom. Sometimes referred to as 2k, 1080p offers a resolution of 2.1 million megapixels.

4k emerged as an option in 2012. It is also known as “Ultra High Definition.” It consists of 3840 pixels horizontally and 2160 pixels vertically. The picture aspect ratio for 4k is usually about 16:9, the same as 1080p. 

4k offers a resolution of 8 million megapixels.
The main difference between the two, in the most non-technical sense, is that 4k offers a sharper image than 1080p. 4k also offers a better contrast ratio than 1080p, meaning that there is a larger difference between the brightest color, white, and the darkest color, black.

Why Does 4k Video Look Better on a 1080p Screen?

When you watch a 1080p video and a 4k video on a 1080p screen, you’ll notice that the 4k video is much clearer and has a far greater contrast ratio. But why is that?

Well, this can be explained with something called chroma subsampling. Chroma subsampling is the process of compressing data.

Ideally, each and every pixel should have its own Y, Cb, and Cr value. Y is the luma value. It tells us how bright the pixel should be. Cb and Cr are the chroma values. They tell us what color the pixel is. If each pixel had its own Y, Cb, and Cr value, it would be referred to as 4:4:4. It would provide the best image quality.

However, to save data, and since our eyes are more sensitive to brightness than color, as long as the Y, the luma value is kept intact, the Cb and Cr values can be shared with their three neighboring pixels. 75% of the Cb and Cr values are, therefore, discarded. Thus, there will be 50% less data. This is referred to as 4:2:0.

As 4k has four times the amount of pixels as 1080p, not only will there be four times more Y or luma values, but there will be four times more Cb and Cr values, making for a clearer, sharper, and more vivid image.

Why You Should Ultimately Switch to a 4k Screen

If you currently have a 1080p screen and are thinking about making a move to a 4k screen, here are five reasons to switch:

  • 4k just looks better on a 4k screen. 8 million pixels, 4 times the amount as a 1080p screen, makes for a better image.
  • Streaming services now offer 4k. Amazon Prime Video, Netflix, Disney +, Vudu, and Youtube now offer 4k videos.
  • Cable and satellite now offer 4k. DIRECTV, DISH, and Xfinity offer 4k content.
  • Game consoles now offer 4k. Consoles like Sony Playstation 4 and Microsoft Xbox One S are compatible with 4k screens.
  • 4k will be around for a long time. 4k video is fairly new, and it will be around for a while.
  • 4k is becoming more inexpensive. With the emergence of 8k screens, 4k screen prices are dropping.

Final Thoughts

The main difference between 1080p and 4k is that 4k has a clearer image. We know this due to chroma subsampling, or color data compression. 4k video, therefore, looks better on a 1080p screen than a 1080p video would look. However, if you want the best quality with a 4k video, you should use a 4k screen.

4k is a thing of the future and will be around for a long time. Streaming services, cable, and satellite all now offer 4k video options. You can also now buy gaming consoles with 4k capability. And of course, 4k televisions and computer monitors are cheaper to buy than ever. So, pick yours up today and join the future!
