It adds support for higher resolutions and higher refresh rates, including 4K@120 Hz, 8K@60Hz and 10K@30Hz. It also introduces a new HDMI cable category called 48G, which certifies cables at the new higher speeds that these formats require. 48G HDMI cables are backwards compatible with older HDMI devices, and older cables are compatible with new HDMI devices, though the full 48 Gbit/s bandwidth is not possible without the new cables.
