HDMI 2.1 is a Serious Upgrade

CES 2017 is currently underway, which means there is plenty of tech news on the way this week, and one of the most exciting so far has to be the reveal of HDMI 2.1 by the HDMI forum.


The specifications are impressive to say the least, and boasts support for 4K, 8K and 10K video with a refresh rate of up to 120Hz. This is all thanks to the new 48G cable, which is backwards compatible with current HDMI devices, which is very useful.

Though useful, this barely holds a candle to the two new features that will be coming to the new audio/video interface, “Dynamic HDR” and “Game Mode VRR” , as they could seriously change the console gaming forever. The press release introduced them as follows:

  • Dynamic HDR ensures every moment of a video is displayed at its ideal values for depth, detail, brightness, contrast, and wider color gamuts—on a scene-by-scene or even a frame-by-frame basis.
  • Game Mode VRR features variable refresh rate, which enables a 3D graphics processor to display the image at the moment it is rendered for more fluid and better detailed gameplay, and for reducing or eliminating lag, stutter, and frame tearing.

What this means for us is the potentially elimination of screen-tearing (how long has this been a gripe of console gamers?) as well as a reduction in the well known console “screen-judder” issue. The addition of a variable refresh rate will also allow developers to target arbitrary frame rates instead of the standard 30 or 60 fps, which is handy for lower budget projects that cannot quite reach 60 but do not want to be limited to 30.

If you’d like to get into the gritty details of what HDMI 2.1 brings to the table, you can head on over to the official press release or take a look at the full specifications.
