Difference Between 4k and UHD

4k and UHD are both high-resolution display standards, but there is a difference between the two. 4k has a resolution of 4096×2160, while UHD has a resolution of 3840×2160. This means that there is a slight difference in the pixel density between the two standards. 4k displays have around 8.3 million pixels, while UHD displays have around 7.5 million pixels. There is also a difference in frame rate support between 4k and UHD. 4k supports up to 60fps, while UHD supports up to 30fps. So which standard should you choose? That depends on your needs and what you plan to use your display for. If you need higher pixel density or faster frame rates, then go with 4k. If you don’t need those things, then UHD will be just fine.

What is 4k?

  • 4k is a term used to describe a display resolution of 4,096×2,160 pixels. That’s 4,000 horizontal pixels and 2,160 vertical pixels. That’s nearly 4 times as many pixels as a 1080p HDTV. 4k is sometimes also referred to as Ultra High Definition (UHD).
  • 4k TVs and monitors are still relatively new and thus expensive. 4k content is also difficult to find. Netflix, YouTube, and a handful of other streaming services offer some 4k content. You can also buy 4k Blu- ray movies, but there aren’t many to choose from.
  • Many new PCs and laptops come with 4k displays, but most don’t come with 4k content to watch on them. 4k monitors are becoming more common in office settings as well. Many 4k TVs and monitors support High Dynamic Range (HDR), which can produce brighter whites and deeper blacks for a more immersive experience.

What is UHD?

  • UHD, or Ultra High-Definition, is a resolution standard for displays and TVs that offers four times the number of pixels as Full HD 1080p. UHD provides a sharper, more detailed picture than HD, and is quickly becoming the new standard for high-end TVs and monitors.
  • While UHD content is still relatively rare, it is gradually becoming more available as streaming services and Blu-ray players begin to support it.
  • UHD screens also offer a wider range of colors and higher contrast ratios than HD, making for a more immersive viewing experience. So if you’re looking for the best possible picture quality, UHD is the way to go.

Difference Between 4k and UHD

4k and UHD are both types of high-definition resolutions. 4k is also known as 4K Ultra HD, while UHD is simply referred to as Ultra HD. 4k offers a resolution of 3840 x 2160, which is 4 times the resolution of 1080p. UHD, on the other hand, has a resolution of 7680 x 4320, which is 8 times the resolution of 1080p. So, what’s the difference between 4k and UHD? Simply put, 4k offers a higher resolution than UHD. However, 4k is also more expensive and requires more powerful hardware to run properly. For most people, 1080p is still the best option.


4k and UHD are terms that are often used interchangeably, but they actually have different meanings. 4k refers to the number of pixels on a screen, while UHD refers to the resolution or quality of those pixels. In other words, 4k screens have more pixels than UHD screens. If you’re looking for a high-quality image with minimal pixelation, go for a UHD TV. However, if you don’t need the best possible picture and want to save some money, a 4k TV will still give you a great viewing experience.
