In Windows 10, you can play HDR (High Dynamic Range) content on an HDR10-enabled built-in display or an external monitor (or TV) connected to your computer.
HDR is a technology designed to improve the contrast and color of the content you see on the screen. Unlike standard dynamic range (SDR), the high dynamic range provides brighter, richer colors and a wider range of detail for better image quality in supported videos, games, and applications.
While HDR technology works easily on powerful smart TVs, it doesn’t work as well on desktops and laptops running Windows 10. You have to make sure your device meets the minimum requirements. You’ll have to manually enable HDR on the screen and in the operating system, and you may run into several problems.
