If you keep up with technological developments around the television or video games in the last three years, you may often hear about HDR. Usually, HDR appears side by side with other terms, such as 4K and UHD. HDR improves the image quality significantly. Just like the movement of technology from SD to HD, Full HD and 4K / UHD a few years ago. TV with 4K or HDR technology is good for your eyes healthy.

Sometimes, talking about this technology display is confusing, we heard about 4K, UHD, and HDR at the same time. However, what are 4K and HDR, exactly? Moreover, what is the difference?

What is 4K and Ultra HD?

4k is about the number of pixels. Technically, 4K is a standard developed in the world of cinema that uses a resolution of 4096 x 2160. On the other hand, UHD is usually used for consumer standard TVs with a resolution of 3840 x 2160 (256 pixels shorter than 4K). The consumer TV standard has an aspect ratio of 1.78: 1. This difference 256 pixels can hardly be seen through the eyes of consumers so that many manufacturers use the terms 4K and UHD together. So, 4k is also commonly referred to as Ultra HD.

Regarding consumer displays, 4K generally have a 3840×2160-resolution panel, which means the 4K screen will offer 3,840 horizontal pixels and 2,160 vertical pixels. This is four times the pixel thickness of a conventional 1080p HD board.

What is the Difference between 4K and HDR?

HDR is the most popular word you often hear when you are talking about a quality of the picture. You might not know what exactly is it. It’s a term that you believe have a proper meaning, but no one has told you exactly why it’s so good for you.

So far, we often heard about HDR, High Dynamic Range, in the world of photography. This technology produces more detailed images by increasing the contrast ratio and expanding the color shades so that the darkest and brightest of the image will still have the detail that you can enjoy.

HDR gives you a different experience of watching television. While 4K might still get many fans because it offers more pixels, but High Dynamic Range (HDR) is the one you should be more focus on. Why? 4K TVs produce four times the amount of pixels than any HD TV on the market, but who cares about this if you still have an awful on the screen?

HDR promises a better picture quality. For bright to be brighter, for dark blacks to be darker and 10-bit panels to display all 1 billion colors finally.

Usually, HDR has another feature which called wide-color gamut (WCG), it allows the TV to produce more colors than most displays are capable of. When the 4K, HDR, and WCG are combined, it will produce the more vivid and lifelike picture. The objects appear more depth. It’s a real improvement to picture quality.

What is an HDR pro?

HDR is such the best thing to have happened in the world of television. It makes the real improvements concerning picture quality. However, to enjoy this advantage, you need a television that can playback such content and content that has been shot in HDR.

To understand what HDR Pro is, firstly you need to know about HDR picture. The primary requirements for HDR10 consist of a 10-bit display panel, full-color space support, and 1000 nits peak brightness. A TV will read the input from HDR content first to be able to reproduce it on the screen. A television which supports for HDR Pro means the television can read the HDR content.

Is Ultra HD the Same as HDR

Both of them are meant to improve your watching experience, but they are hugely different technologies. It’s all about quantity and quality. UHD is about the number of pixels, while HDR wants to make the actual pixels more accurate. Whether you’ve got a 32 inches’ unit in the bedroom or the bigger one in the living room, HDR makes a visible difference.

Of course, 4K and HDR tend to come hand-in-hand. The most of HDR-compatible televisions on the market are also 4K Ultra HD TVs. Some 4K TV sets do HDR much better than others, and you need to pay around $2000 to get a good one right now, and it’s expensive enough especially for 75 inch 4k tv.

You know that HDR is still a high-end feature, and it will take a long time for more HDR content to become widely available. There’s nothing amiss with getting a 1080p TV at this moment if you needn’t bother with a 4K HDR TV yet.
