Announced hdmi 2.1 specification, 8k at 120 fps, better colors and dynamic hdr

HDMI Forum has put the batteries before the great threat of DisplayPort and has already announced the new HDMI 2.1 specification that promises great advances among which we can mention the ability to play video at 8K and 120 FPS, better colors and dynamic HDR as the details more important.

First details of the HDMI 2.1 specification

The first 8K monitors are already on the way so you have to put the batteries and that is just what they have done with HDMI 2.1. This new specification multiplies by 2.6 the bandwidth of the revision 2.0 to reach 48 Gbps. With this it is possible to offer video at a high resolution of 8K 7680 x 4320 pixels at a speed of 60 FPS and 4: 4: 4 subsampling, it is also possible to play at 8K and 120 FPS with 4: 2: 0 subsampling. The other great thing about HDMI 2.1 is that it enables dynamic HDR metadata with frame-by-frame control of color, contrast and brightness levels.

We recommend the best monitors for PC.

In the second quarter of 2017 we will have the final specification of HDMI 2.1 while the first compatible devices are expected by the end of the year or 2018.
