What Is UHD?

UHD, or Ultra High Definition, refers to a resolution that offers four times the pixel count of Full HD (1920×1080), resulting in a display resolution of 3840×2160 pixels. This increased pixel density leads to sharper images and more detailed visuals, making it ideal for large screens where you can notice the difference in clarity. UHD also often encompasses enhancements in color precision and compatibility with high dynamic range (HDR) content.

The term UHD is commonly used in the context of televisions and monitors, but it also applies to video content and streaming services that provide media in this high-definition format. Ultimately, UHD enhances the viewing experience by delivering more vivid, cinematic scenes and making images appear more lifelike.

What Is HDR?

HDR, or High Dynamic Range, refers to a technology that allows for a broader range of luminosity compared to standard dynamic range (SDR). This means HDR can display both very bright and very dark elements in a single scene more effectively, resulting in richer contrast and more detail in shadows and highlights. HDR content provides a more realistic representation of scenes, as it mimics the way the human eye perceives light and color.
