HDMI 2.1: Faster and with a resolution that will reach 10k

The new HDMI 2.1 version brings several new features. The announcement took place last Tuesday at the HDMI Forum and promises much bigger analyzes, new HDR features and increased speeds in games and multimedia. But let's look at the changes in more detail:

HDMI 2.1


  • HDMI 2.1 provides much more bandwidth than its predecessor, HDMI 2.0. The 48Gb / s from 18Gb / S is a glaring difference that offers incredible speeds to even the most demanding.
  • The physical connection (plug) is the same and there is full compatibility with the HDMI 2.0 ports.
  • The analysis range reaches very high levels as it can transfer 4K to 120Hz, 8k to 60Hz and 10k for commercial or industrial purposes.
  • Dynamic HDR support ensures that each video snapshot is projected at the ideal depth, depth, brightness, contrast, and wider color ranges.
  • The eArc service simplifies connectivity, provides more ease of use and supports the most advanced audio formats.
  • The refresh rate is upgraded and ensures a smooth and more real movement in games, movies and videos. 3 major changes are:
    1. Variable Rake Rate (VRR) reduces or eliminates decay, stutter and tear of the chassis for more fluid and more detailed gameplay.
    2. Fast media swap (QMS) for movies and videos eliminates the delay that can lead to blank screens before the content appears.
    3. Fast Frame Transfer (QFT) reduces the delay for smoother gaming without lagging and interactive virtual reality.
  • Automatic Low Delay (ALLM) allows automatic adjustment of the ideal delay by allowing smooth and uninterrupted viewing and interactivity.

Surely most of these changes can not be understood as some equipment (4k Screens, Games and 4k and VR Eyewear 4k support) is a technological development that will bring many benefits in the future. Official release of 2018-2019 is expected.
