This latest version of HDMI offers several new features that greatly enhance the home entertainment experience. In this blog, we will discuss the possibilities with HDMI 2.1 and how they can improve your home entertainment setup.

Higher Video Resolution

HDMI 2.1 supports video resolutions up to an astonishing 10K (10,240 x 4320) at 60Hz. This means that you can enjoy the highest quality video content with unmatched clarity and detail. Whether you're watching movies or playing games, the higher resolution will provide an immersive experience like never before.

Higher Refresh Rates

HDMI 2.1 supports refresh rates up to 120Hz, which means smoother video playback and gaming. The higher refresh rate eliminates the need for motion smoothing, providing a more natural viewing experience.
