What is better Ultra HD 4K or 4K HDR?


Home entertainment technology has always been in full swing thanks to the more recent inventive innovations incorporated into the next-generation television such as HDR and UHD. The concept of watching television has altered with the introduction of Smart TV integration with the Internet of Things. TVs these days are used for more than just watching movies or television. TVs have improved user experiences in a number of areas, including gaming, watching movies, making video calls, and other activities. The HDR vs. UHD debate dominates modern TV discussions.

It might be challenging for many people who want to purchase televisions to decide which option is ideal. We don’t blame you, either! It can be challenging to understand the technical jargon. But do not fear, we are here to answer your query, “HDR Vs. UHD Which is better?” by explaining the distinctions between HDR Vs. UHD TV.

Important distinctions between 4K UHD and 4K HDR

Since 4K UHD and 4K HDR refer to separate parts of display technology, you cannot directly compare them, but you can see their key distinctions below.

Important distinctions between 4K UHD and 4K HDR


  • A 4K UHD screen has an image resolution of 2160 rows and 3840 columns of pixels. Because UHD panels are often of 4K grade, it is only ever referred to as 4K resolution in the tech industry.
  • 4K describes the level of detail in the exhibited image, which is based on its resolution.
  • The color quality of 4K UHD is highly vibrant. This is a result of the incredibly high definition picture. Color enhancement in 4K often does not employ color gamut technologies.
  • Although you think the color quality is higher, 4K UHD doesn’t actually improve quality. It appears as though the quality of color has improved due to the improvement in definition.
  • You must ensure that the source and display are entirely compatible with 4K content when thinking about compatibility with external devices.
  • Streaming services like Netflix and Amazon Prime Video offer 4K content.


  • A screen with 3840 rows and 2160 columns of pixels that accurately reflect color brightness and contrast is referred to as 4K HDR.
  • Many other resolutions, including 4K, are compatible with HDR technology.
  • Compared to ordinary 4K UHD, 4K HDR significantly raises the visual quality. The picture becomes more lifelike as the definition and depth of the image are improved.
  • The wide color gamut technology utilized in 4K HDR is what gives the colors a boost.
  • It has a stronger visual impact. The definition of light and shadow is maximized, and the color and contrast are dramatically improved.
  • HDR stands out from other technologies because to its higher color accuracy and contrast ratio.
  • There is more space between white and black in 4K HDR. Without changing the definition of bright and dark hues, this increases contrast.
  • There are numerous formats for this type of television. The source and display of the devices, however, ought to be compatible with one another.

Describe 4K UHD

At the moment, 4K is the ideal image resolution. It’s unlikely that 6K and 8K resolutions will become widely used in projectors for at least a few more years, despite the fact that they are closely following 4K and are already accessible in a wide selection of TVs.

The precise image resolution is 3840 x 2160 pixels, which offers a plethora of details and is thought to be more than adequate for the majority of uses, from casual movie viewing to professional photo editing.

The majority of professionals, like photographers and graphic designers, utilize 4K resolution because it offers vibrant colors and better image quality than FHD, which is the resolution level below UHD.

Describe 4K HDR

HDR is a tool that complements image resolution rather than replacing it. By enabling the device to display more detail in both the extreme whites and blacks, High Dynamic Range (HDR) imaging is a technique for producing a better range of luminosity than Standard Digital imaging.

Since they are two entirely different things, 4K HDR is in no way in competition with 4K UHD. In reality, 4K HDR doesn’t care about the screen’s resolution. This type of television scenes, however, typically have a 4K resolution.

Finding Your Best Option Between 4K UHD and HDR

Let’s examine the fundamental distinctions between HDR and 4K UHD.

4K Resolution: What is it?

HDR has nothing to do with resolution, but 4K refers to a specific screen resolution. The term “HDR” refers to any video or display with a higher contrast or dynamic range than SDR material. This type of television has conflicting standards, some of which mandate a minimum 4K resolution.

4K can refer to one of two resolutions for digital televisions. The Ultra HD or UHD format, which has 3,840 horizontal pixels and 2160 vertical pixels, is the most popular. The less popular resolution is 4096 x 2160 pixels, which is mostly used with movie and theater projectors.

The next greatest resolution you’ll find on a consumer television is 1080p, and each 4K resolution has four times as many pixels (or twice as many lines) as that display. In other words, one 4K resolution image takes up the same space as four 1080p photographs. The total amount of pixels in a 4K image exceeds eight megapixels with an aspect ratio of 16:9, or 16 by 9.

No matter the size of the screen, 4K (and all other TV resolutions) stay constant. PPI, or pixels per inch, can, however, change depending on the size of the screen. In order to maintain the same resolution, pixels must be larger or farther apart as the TV screen gets bigger.

To qualify as HDR, a television must adhere to a set of requirements for brightness, contrast, and color. While these standards differ, all this type of television displays are required to have a minimum 10-bit color depth and a dynamic range that is higher than SDR. As 4K TVs, which are the majority of this type of television, most feature a resolution of 3840 by 2160 pixels (there are a small number of 1080p and 720p HDR TVs).

Peak brightness output on some LED/LCD HDR TVs can reach 1,000 nits or higher. A minimum peak brightness of 540 nits is required for an OLED TV to be considered this type of television. The majority have an 800 nit maximum.

HDR’s use of color and contrast

HDR televisions offer significantly better color reproduction. With the exception of adding definition, 4K resolution has no impact on color. This is why 4K and UHD frequently go together. The two most crucial components of picture quality—definition and color—are complemented by these technologies.

The separation between white and black is widened with this type of television technology. This increases contrast without overexposing or underexposing the dark or bright colors.

When high dynamic range photographs are taken, the data is used in the editing process to grade the material and achieve the broadest contrast range. Wide color gamut is produced by grading the images, which results in richer, more saturated colors as well as smoother shading and more detailed images. Each frame or scene can be graded individually, or static reference points can be used to grade a full movie or television show.

Bright whites show without blooming or washout and deep blacks appear without muddiness or crushing when an HDR television recognizes this type of television-encoded content. The colors are more saturated, to put it simply.

For instance, in a scene of a sunset, you should be able to clearly distinguish between the bright light of the sun and the darker areas of the image, as well as all the brightness levels in between. Look at the illustration below.

A TV can show HDR in one of two ways:

  • HDR Encoded Content: HDR10/10+, Dolby Vision, HLG, and Technicolor HDR are the four main HDR formats. Which formats an HDR TV is compatible with depends on its manufacturer or model. A TV shows the images in SDR if it can’t find an appropriate this type of television format.
  • Processing from SDR to HDR: this type of television examines the contrast and brightness characteristics of an SDR stream in a manner similar to how TVs upscale resolutions. The dynamic range is then increased to roughly HDR grade.

A Comparison of 4K UHD and 4K HDR

Although 4K UHD and 4K HDR designations on projectors and monitors frequently cause confusion, you don’t actually have to select between the two.

It often depends on personal preference which of 4K HDR versus 4K UHD you actually prefer. Both provide you an amazing display that is significantly better than that seen in any Full HD devices.

Just keep in mind that HDR produces images with a wider dynamic range, meaning that both blacks and whites have more detail, even though there isn’t much of a difference between UHD and this type of television standards in practice.


To generate legitimate or true 4K resolution, 4K televisions need end-to-end compatibility across all components. HDR generally reflects the same. Both an HDR TV and material created in the HDR format are required. In some ways, HDR video is less accessible than 4K content, although this is starting to change.

You will eventually need 4K-compatible devices in order to enjoy full 4K UHD resolution. In addition to the original resolution of the content you’re watching, this includes home theater receivers, media streamers, Ultra HD Blu-ray players, and 4K video projectors. A high-speed HDMI cable is also required. Because the difference between 4K and 1080p is less obvious on screens less than 55 inches, 4K is more popular among larger televisions. Nevertheless, this type of television effect may seem differently on each TV, depending on how much light the panel produces.

While some 4K devices can upscale lesser resolutions to 4K, the process isn’t always seamless. Over-the-air (OTA) content will need to be upscaled in order to view in 4K because 4K has not yet been deployed in over-the-air TV broadcasting in the United States. Not all HDR TVs can upscale from SDR to this type of television, for the same reason. Consider the TV’s compatibility with HDR10/10+, Dolby Vision, and HLG formats when buying for an HDR-capable TV. You should also look at the TV’s peak brightness capability, which is expressed in nits.

How well a TV with HDR displays The brightness of the TV affects HDR. Peak brightness is what is used to describe it, and it is expressed in nits. For instance, content encoded in the Dolby Vision this type of television standard may offer a 4,000 nit difference between the darkest black and the lightest white. There aren’t many HDR TVs that produce that much light, but an increasing number of displays do. Most this type of television show fewer images.

OLED TV brightness peaks at around 800 nits. While more and more LED/LCD TVs emit 1,000 nits or more, more affordable models may only do so by 500 nits (or lower). On the other hand, OLED TVs may offer a higher perceived dynamic range even with lower peak brightness levels since each pixel in an OLED TV is separately lighted, allowing the pixels to display absolute darkness.

Tone mapping is used by TVs to match the dynamic range of HDR material with that of the TV’s light output when they detect an HDR signal but are unable to emit enough light to display it fully dynamically.


Colors, contrast, and pixels all have a role in sharpness and definition. With HDR, the emphasis is mainly on giving a variety of overtones and undertones while creating stunning photos.

On the other hand, 4K UHD has around 8 million pixels and can generate a clearer image. In order to view crisper photographs, it would be ideal if you had compatible devices. Additionally, bigger screens, when used with suitable sources, do a better job of showing the power of 4K.

Do You Have to Choose Between 4K and HDR?

You do not have to choose between 4K and this type of television because they are not conflicting standards. You don’t need to prioritize one standard over the other because the majority of high-end TVs meet both standards, especially if you’re purchasing a TV that is larger than 55 inches. Since you generally won’t notice the resolution difference if you desire a smaller TV than that, you might be OK with a 1080p monitor.

If you’re on a tight budget, this type of television is a fantastic choice because, despite its low cost, it still offers fantastic colors and contrast.

Is 4K UHD Costlier Than HDR?

Price-wise, 4K UHD and HDR are comparable. When 4K originally debuted in 2014, the cost was expensive and there was little demand. However, the cost has significantly dropped over time, virtually matching this type of television.

Video games and streaming devices have raised demand for 4K TV. Even with this type of television, larger displays produce better visuals with 4K, which is inherently more expensive than normal television.

Overall, buying a 4K UHD TV will probably cost you more money, especially when you include in the costs of HDMI, streaming devices, and other equipment needed to fully utilize 4K.

Is 4K more superior to HD or HDR?

Which visual quality is superior will ultimately depend on your needs. For instance, because it generates a crisper definition and a greater frame rate, 4K is superior on devices that support it. HDR, on the other hand, adds more colors and contrast while costing a little less. If the content is 4K compatible, HDR is less crisp than 4K.

Is 4K UHD Required?

Most consumers did not feel the need to purchase 4K UHD when it first became available in the middle of the 2010s because it was just HDMI and Blu-ray compatible. However, 4K content started to be produced for television shows and streaming services. As technology catches up with the entertainment industry, people are choosing 4K televisions even if they cost a little more than this type of television or HD.

Do smartphones, cameras, and screens all support HDR?

No, HDR is HDR, even though this type of television content must be created with an HDR camera and seen on an HDR monitor. The capabilities of this type of television vary depending on the device, but the technology remains the same.

When Compared to 4K, Is HDR Relevant?

Many individuals are unaware that we regularly utilize this type of television. This type of television is used, for instance, by photography and smartphone cameras. Because of its affordability and color accuracy, HDR TVs are still widely used. While prices for 4K are almost on level with this type of television, 4K’s popularity is still rising.

In order to fully utilize 4K UHD or HDR, you must ensure that every link in the chain does so. For instance, in order to watch a movie in 4K UHD, you must to have a TV and Blu-ray player that support it. Otherwise, it would only be able to display at the weakest link in the chain’s highest resolution.

Do I need to use HDR?

The choice is yours. It’s likely that you’ll want to use your HDR camera or phone if you have one. Whether you want to use HDR in a TV or monitor will probably depend on how well it is implemented.

Final Thoughts

Both UHD and this type of television are crucial components of image quality, especially if you’re showing a really dark image where it could otherwise be difficult to distinguish features. However, whether or not you need them actually depends on you.

Ideally, attempt to thoroughly research each of them by going to a store to see the differences in person. This will help you decide whether you need them on a regular basis or not. Remember that it’s crucial to assess your screen requirements for gadgets like laptops and projectors because you’ll likely be using them every day and don’t want to cut any corners here.
