With the advent of Ultra high resolution/4K solutions, comes the need for a new set of standards that deliver this high bandwith performance in a new range of AV products.

HDMI 2.0 is one of these upgraded standards and represents a significant upgrade from the current generation of HDMI in several ways – not just limited to video resolution. There are several other performance improvements that HDMI 2.0 enables in areas like audio quality, screen aspect ratios and remote control capabilities.

Some of the key features we can expect from HDMI 2.0 are:

Supports higher data bandwidth of 17.82 Gbps to meet the needs of 4K quality – including video, audio and control information
Allows a higher a 60 frame per second refresh rate (compared to 30fps for HDMI 1.4) for better images and 8 bits of color information for three separate colors per pixel
Allows 21:9 displays, moving beyond 16:9/10 that is common today
Supports CEC 2.0 to enable more standardised or universal remote control standards (consumer electronic control)
Upto 32 channels of audio (up from 8 channels now) to take sound experiences even further
