High Dynamic Range or HDR is a technique that’s used to create lifelike videos which have improved and better dynamic range, especially when it comes to details. And as you know, Windows 10 supports the steaming of HDR videos as long as the display supports it and it comes with the option to enable the HDR Playback for Windows 10 Video Streaming apps. However, before you can get the best viewing experience, you need to calibrate the display further for HDR video on your Windows 10 PC. Take note that even when you have the HDR Playback feature enabled on your computer, you still need a display that supports it. To make sure that your display supports this feature, you can use the DirectX Diagnostic Tool to have the display correctly wired and have the latest WDDM 2.4 drivers installed as well as set the other settings properly. Once you’ve made sure that your computer’s display really supports HDR and you’ve already enabled the HDR Playback feature, now it’s time for you to calibrate. Remember that when you calibrate the display, you should make an external monitor your primary display if you are using it for HDR and then adjust the settings to your liking. And if you are calibrating for primary display, you need to disconnect all other displays.

Follow the given steps below to calibrate the display of your PC.

• Step 1: You need to open the Video Playback first. To do so, navigate to Settings > Apps > Video Playback.
• Step 2: Under the Video Playback settings, uncheck the “Don’t increase display brightness when watching HDR video on battery” checkbox or plug in your PC.
• Step 3: Next, click the “Change calibration settings for HDR video on my built-in display” link located on the right side.
• Step 4: After that, click on the Play button located on the left side to play the video. Then move the sliders to the left or right so you can start to calibrate. Once you see that the quality of the image is to your preference, stop.

Note: Just a tip when calibrating – you just have to find the right balance between the details in the darker parts of a scene. For instance, you have Mountains in the background and buildings in the front – you need to drag the slider to the right to add more details to the snow on the mountain or drag the slider to the left to add more details to the buildings. After that, you can pause the video and exit the full-screen mode. Keep in mind that the quality of HDR depends on you as it is a personal choice. Some users might like a brighter shade while other ones want the darker shade so it really depends on your taste. If you are not satisfied with how your HDR turned out, you can just try calibrating the display again. Simply go back to the default HDR video calibration and click or tap the Reset calibration button. Another thing to remember. First, you can only see HDR content on the full screen and if you’re using a laptop, you need to make sure to watch videos when plugged in and check that the battery settings won't’ lower the brightness.
