Version 1.3 HDMI cable

HDMI 1.3 increased the single-link bandwidth to 340 MHz (10.2 Gbit/s).It has the ability to support Deep Color, with 30-bit, 36-bit, and 48-bit xvYCC, sRGB, or YCbCr, as opposed to 24-bit sRGB or YCbCr in earlier HDMI cables.

It has the ability to support Dolby TrueHD output as well as and DTS-HD Master Audio streams for external decoding by AV receivers.

Audio syncing capability is also possible. It can also support Type C Mini connectors for portable machines.

HDMI 1.3a was modified for Cable and Sink purposes, undershoot and maximum rise/fall time limits were removed. CEC capacitance limits were modified, along with clarified sRGB video quantization range, and CEC commands for timer control were reintroduced albeit slightly differently in that audio control commands were added. The ability to optionally supportĀ  streaming SACD in its bitstream DST format rather than uncompressed raw DSD was also included.

HDMI 1.3b, 1.3b1 and 1.3c do not offer different HDMI abilities but refer to testing for compliance.
