Just as you were getting comfortable with HDMI® 2.1, a new kid by the name of HDMI® 2.1a, has come to town to shake things up yet again.

HDMI® or High Definition Multimedia Interface, has continued on its evolutionary path as a standard since it was first introduced in 2002. One of its benchmarks, for example, was with 1.3, which brought glorious 3D capability. Another was 1.4, that became the standard Internet data connection, with high-definition, digital audio and video. When HDMI® 2.1 came onto the scene, it was introduced for gamers, with greater bandwidth of 48 Gbit/s (or gigabits per second) and resolutions up to 10K.



  • • It offers 10 or more bits per color.
  • • The image HDMI® 2.1a delivers has better depth, contrast, brightness, detail and colors than previous versions of HDMI®.
  • • It supports higher resolution for video and refresh rates at 8K60Hz and 4K120Hz.
  • • It has Dynamic HDR (High Dynamic Range), with improved video images and better details in both lighter and darker sections of each image.
  • • It features Source-Based Tone Mapping or SBTM. This maps colors through video signals that automatically adapt to the display in use, for additional HDR and improved video experience.
  • • When using the Ultra High Speed HDMI® Cable, it has backwards compatibility that works with earlier HDMI® technology. It also features low EMI (Electromagnetic Interference) emission and up to 48G bandwidth support.
