Have you ever been bogged up in some technical jargon, such as HDR, UHD, or 4K? Of course, you know that these terms are about videos. But did you know their differences, usage, and features? For instance, you are asked to choose between 4K UHD or 4K HDR, can you identify the reason why you chose one over the other? This post will help in having a deep knowledge about these terms and knowing their differences.

4K UHD V.S. 4K HDR: Brief Introductions to 4K UHD and HDR

What exactly is 4K?

In terms of consumer displays, 4K usually refers to a panel with a resolution of 4096×2160-pixels. This translates to 3,840 horizontal pixels and 2,160 vertical pixels on a common 4K screen. When these statistics are added together, you obtain a panel with over 8 million pixels. A typical 1080p HD panel has four times the pixel density. 4K resolution has been commercially accessible since 2014, and it is now a common feature for picture quality.

What is 4K Ultra-High Definition (UHD)?

Ultra-High-Definition, or UHD, is a word used interchangeably with 4K. As mentioned before, 4K UHD means 4096×2160 resolution for videos, while UHD televisions have a 16:9 aspect ratio on their screens. 4096 × 2160 pixels becomes a common resolution that is usually reserved for theatre and movie projectors. Ultra-High-Definition televisions have a better resolution and frame rate than conventional 1080p televisions (which is why it is also called 4K-UHD).

What is 4K High Dynamic Range (HDR)?

While 4K and HD refer to resolution, High Dynamic Variety (HDR) refers to the range of tones in a video. Many TVs now incorporate both HDR and 4K UHD technology, resulting in 4K HDR TVs. When watching recordings on a conventional TV, a lot of detail is lost because the screen can't display the entire spectrum. HDR displays have a greater range of brightness and color, giving the movie a more realistic appearance.

HDR TVs often display a nearly ideal amount of brightness for the bright portions and blackness for the dark areas of a picture, thanks to Wide Color Gamut technology. To put it another way, HDR technology is ideal for viewing everything in the proper light and color contrast.

4K UHD V.S. 4K HDR: What Are the Differences between UHD and HDR

Actually, UHD and HDR appear to be two separate technologies. Yes, they are, yet they complement each other well. Because of its superior picture quality, UHD has become the preferred entertainment standard for media devices. HDR is merely a camera setting that improves the visual quality of UHD. The fundamental distinction between UHD and HDR is that UHD is a resolution format, whereas HDR is a hardware feature that enhances the colors and contrasts of a UHD display. Many TVs now use both HDR and 4K UHD technologies, which are called 4K HDR TVs.

The following table summarizes the differences between 4K UHD and 4K HDR:

A screen having 3840 horizontal resolutions and 2160 vertical resolutions is commonly referred to as a 4K display (4K resolution).A screen with a horizontal resolution of 3840 pixels and a vertical resolution of 2160 pixels, displaying the proper amount of luminance and color contrast.
The enhancement of color in 4K comes from a higher level of definition.Color and contrast are significantly developed in the visuals. Color definition, light, and shadow are all displayed to their utmost potential.HDR stands out because of its color precision and strong contrast ratio.
The quantity of image resolution is what 4K UHD is all about.4K HDR can increase image quality by capturing the image’s depth and definition.
A full 4K-compatible device is required for both the source and display equipment in terms of device compatibility.Because there are so many HDR formats to choose from, device compatibility should be complete in both the source and display cases.
Nowadays, 4K material is widely available, especially on famous OTP platforms (Netflix, Amazon prime).In comparison to 4K video, the amount of HDR content available is somewhat restricted.
4K televisions are the most common UHD televisions.Other than 4K, HDR technology can be found in devices with a variety of resolutions.
