The full High Definition (HD) options have been in the market for a while now. And now we have newer options emerging which are better than Full HD.

Over the last few years, two such options in this genre are 4K and UHD. Both of them have been fundamentally different terms, signifying two of the best display options. Full HD has given away to Ultra HD (UHD) which has also been somewhat overthrown by the 4K. And finally, we have the 8K which is the most advanced display technology.

But from everything mentioned, UHD and 4K have been used interchangeably by some companies and brands. Although they make a lot of difference to the viewers, they are still not the same thing. And this article will help you know the difference between UHD and 4K.

Difference between UHD and 4K

Further in this segment we discuss the basic differences between UHD and 4K displays. So that you have a clear opinion.


There is a slight difference between the resolution of the two types.

  • UHD, or Ultra High Definition, is the next advanced step from the Full HD (High Definition). So the full HD has a resolution of 1920 x 1080p. And as Ultra High Definition is its successor, it doubles the resolution. The resolution of UHD is 3840 by 2160 pixels. And the screens with UHD displays usually have an aspect ratio of 1.78:9.
  • The 4K screen is probably the most popular of screen resolutions which has gained fame. Initially standardized by a consortium of motion picture, Digital Cinema Initiatives. The 4K in the name stands for the roughly 4000 horizontal pixels in the display. And as seen, more than that of the UHD displays. The exact resolution of 4K screens is 4096 x 2160 pixels.


Although now both of them have wide uses, they were initially made for distinct purposes.

  • UHD screens were particularly introduced to be used in the professional display market. And this means that these screens are meant to be used in monitors, televisions and the like. 
  • 4K screens have different uses. So for the display markets, 4K screens work the same as the UHD. 

But 4K screens originally come from the cinematic universe. This is actually a cinematic terminology. And these had wider resolution than others because of cinema projectors and video editors. These projectors as well as video editors worked perfect in the 4K resolution. 

What is 4K UHD?

Although being two different terms, they have been very interchangeably used in recent days. With the innovation of both of them, the brands and companies have jumped to the rescue. And they have brought the best of both worlds together resulting in 4K UHD screens. 

Also, these screens were different and much more advanced than the full HD screens. 4K UHD screens have two different definitions of 3840 by 2160 pixels and 4096 by 2160 pixels.

Usually the former resolution is used in products. Because the 4K resolution needs specific equipment to operate. So you will need a 4K panel, a HDMI 2.0 port and other specifications too. 


Q – Can you tell the difference between 1080p and 4K?

A – Of course there is a difference between 1080p, i.e. Full HD, and 4K. As 4K screens have nearly four times the number of pixels in 1080p. And as the pixel density plays a major role in the formation of images. When there are more pixels, you get a clearer and more crisp image.

Hence, theoretically 4K screens are better here. But for us viewers, this is not a very major difference. Although yes, you see 4K screens with clearer and crisper images, it all depends on the size and angle of screens.  

Q – How does 1080p look on a 4K screen?

A – You do not see any actual difference when you watch 1080p content on a 4K screen. And it is basically the same when you watch it on a 1080p or a Full Hd screen.

Basically, you do not see a difference because the video content itself is made for 1080p screens. And watching it on a 4K screen does not change the video’s quality.

Q – Does 4K look good on a 1080p screen?

A – When you watch 4K content on a 1080p screen, you are watching higher resolution content on a smaller screen. And this means that more pixels are displayed across the 1080p screen. So you get a vibrant, clear and sharp image on the screen.

Q – Where do you see the most of the 4K content?

A – 4K content is usually found in the cinemas. As per that, we see major 4K content in the movies. And when you talk about the streaming sites, Netflix has most of the 4K content. And as Netflix is compatible with monitors and TVs, you can enjoy it anywhere.

Q – Should I buy UHD or Full HD?

A – So Full HD has 1,920 x 1080 pixels and UHD has 3,840 x 2,160 pixel resolutions. And when there is a high pixel density, there is greater resolution. With better resolution comes a better picture quality. Hence, if you have a decent budget, you must go for UHD.
