What is 4K? What is HDR? What is UHD? What are the differences between them? Which one is better? Which one to choose? This post from MiniTool introduces information about HDR vs 4K and 4K UHD vs 4K HDR for you.
First, let’s see the overview of HDR, 4K, UHD.
Overview of HDR, 4K, and UHD
What Is 4K?
The resolution of an ordinary high-definition TV is 1080p. In simple terms, it is 1920 x 1080 pixels: 1920 pixels cross the display horizontally, and 1080 pixels cross the display vertically. 4K TV simply increases the number of pixels: Generally, 4K refers to a display resolution of 2160p or 3840 x 2160 pixels. This is approximately four times that of a 1080p picture, so it is called 4K.
What Is HDR?
High dynamic range (HDR) refers to the contrast between black and white in an image. The higher the dynamic range, the closer the photographic vision is to real life. HDR provides a higher contrast range, allowing finer details to be obtained in the shadows between them.
Recent new updates have made Windows 10 support HDR10. Check how to turn on HDR in Win 10 to better experience games, 4K movies, apps, etc. on Windows 10 PC.
What Is UHD?
UHD or Ultra HD TVs are commonly referred to as 4K, which means that the horizontal screen resolution is approximately 4000 pixels.
HDR vs 4K
Next, we will introduce details about HDR vs 4K.
HDR vs 4K: Resolution
The first aspect of HDR vs 4K is resolution. 4K refers to a specific screen resolution, and HDR has nothing to do with the resolution. For digital TV, 4K may mean one of two resolutions. The most common is the Ultra HD or Ultra HD format of 3840 x 2160 pixels. The less common resolution is 4096 × 2160 pixels, which is mainly used in movie theaters and movie projectors.
Thus, HDR vs 4K for resolution, 4K is better.
HDR vs 4K: Color and Contrast
Next, let’s see HDR vs 4K for color and contrast. As a resolution, the effect of 4K on color is mainly through higher definition. Significantly improve color reproduction and contrast. HDR has a greater visual impact than 4K. Greater visual impact than SDR. More accurate colors, smoother light and color vignetting, and more detailed images.
In addition to providing additional clarity, 4K will not have much impact on colors. HDR expands the distance between black and white. This makes the contrast stronger without overexposing bright colors or underexposed dark colors.
Thus, HDR vs 4K for color and contrast, HDR is better.
HDR vs 4K: Compatibility
Full 4K Ultra HD resolution requires 4K compatible devices from the source to display, including set-top boxes or Blu-ray players, streaming media devices, HDMI cables, and TVs. HDR needs end-to-end compatibility. Compared with 4K, the available content is limited.
Thus, HDR vs 4K for compatibility, HDR is better.
4K UHD vs 4K HDR
If you choose 4K for your TV, there will come out another issue – should you choose 4K UHD or 4K HDR?
4K UHD is mainly defined as a screen with 3840 × 2160 (4K resolution). The screen with 3840 × 2160 vertical resolution of 4K HDR demonstrates proper brightness and color contrast. UHD TV is usually 4K HDR technology that exists in devices with different resolutions other than 4K.
4K UHD is about the number of image resolutions. 4K HDR can capture the depth and clarity of the image and improve the quality of the image. 4K UHD generally does not use color gamut technology. 4K HDR provides wide color gamut technology.
Here is all the information about HDR vs 4K and 4K UDR vs 4K HDR. I hope that this post is useful to you.
