Buying the best TV for your home is no more a duck-soup. With all the tech jargon popping out, the process can be intimidating to any commoner.

4K UHD vs 4K HDR

But before we get on to it, I would love you to know everything about 4k televisions. The tech world is progressing, so what’s holding you back? The concept of 4k has been introduced only to enhance your television experience. Let’s dive into it right away.


What is 4K television?

In layman’s language, 4K televisions have a high pixel density. Compared to a traditional Full HD TV, 4K TVs have four times more pixels. This clearly means the picture quality will be more authentic and explicit even if the screen size is similar. You will definitely not miss the minutest detail on the screen.

4k resolution represents a horizontal display resolution of roughly 4,000 pixels. The more the pixels, the more detailing of the picture you will have. The dominant 4k standard in television should be about 3840*2160. However, this can happen only if the content is delivered in 4k with minimum broadband of 15Mbps.

What are the advantages of a 4K TV?

  • 4K Televisions generally come in large screen sizes.
  • The technology brings out more detail in the picture quality.
  • These televisions have a better image depth.
  • 4K TVs also have a potential to handle colour better.
  • You can experience a mesmerizing TV experience at home.
  • 4K TVs also have budgeted options.
  • These televisions let you recapture a cinema at a high resolution.


What is 4K UHD?

Let me begin by pointing out what UHD stands for – Ultra high definition. In a nutshell, these resolutions create a pixel count of 4k. This is 4 times of a full HD TV (1080p). This resolution converts to 8 million pixels being crowded in the space in which a full HD TV fits only 2 million. The more the pixel count, the better the resolution. So, the viewer can expect an absolutely clear image and precise colours.

Since every pixel is minute, it is assigned to a small slice of a larger picture. These extra pixels have a large impact on the large screen.

According to the Consumer Technology Association (CTA), 4K Ultra-High Definition TVs have 3840 pixels horizontally and 2160 pixels vertically.

The demand for large-sized televisions have escalated, and how! This is the prime reason for the incorporation of the UHD technology.

What are the advantages of 4K UHD televisions?

  • UHD TVs deliver a crisp and sharp image.
  • The transition between scenes is very smooth.
  • UHD technology ensures zero pixelation.
  • UHD TVs offer increased content extensibility from channels to Blu-ray.
  • UHD televisions are completely 4K.

What are the disadvantages of 4K UHD televisions?

  • While you can enjoy colourful images, sharp displays and advanced technologies, remember everything comes at a cost. The biggest disadvantage of a 4K UHD TV is the high price.
  • UHD televisions have a lack of content options.
  • UHD technology is not available in a compact size TV.

What is 4K HDR?

HDR, also known as High Dynamic Range, has nothing to do with the pixel count like UHD. HDR technology is about the picture and colour luminosity. The smart technology modifies the colour, brightness and contrast to a level that is well suited for a supreme visual experience. It certainly makes the picture quality more rich and realistic. It brings images to life in the true sense by keeping away any bleeding of pictures.

However, for this accurate image result, you need content with the right HDR metadata. But this shouldn’t stop you from visually treating your eyes. Today, HDR content is available on everything – Blu-rays, streaming apps and more.

Not all 4K UHD TVs have HDR capabilities. But most of the 4K products have the HDR feature. That’s how you can derive the benefits of 4K HDR technology.

What are the advantages of 4K HDR televisions?

  • The prime advantage of HDR televisions is to provide better brightness and contrast.
  • You can experience more vivid images.
  • HDR technology will give a more realistic image. It is sure to be closer to how content creators wanted it to be.
  • HDR TVs provide a greater visual impact compared to TVs with SDR technology (standard dynamic range).
  • HDR technology has a wide colour gamut.
  • Most game consoles have the HDR feature.

What are the disadvantages of 4K HDR televisions?

  • You can derive benefits only on HDR-compatible TVs.
  • HDR on a budget HDR TV will look worse than a non-HDR TV.
  • Some HRD TVs have a default backlight and contrast level setting. You cannot adjust the HDR mode.

One Last Thought

4K UHD vs 4K HDR: In this debate, we have discovered that comparing both technologies is slightly tricky.
