HDMI Announces USB-C to HDMI Cables for 4K Displays and TVs

The licensing group behind the HDMI interface has introduced a new HDMI Alternate Mode (http://www.businesswire.com/news/home/20160901005070/en/HDMI-Releases-Alternate-Mode-USB-Type-C%E2%84%A2-Connector) that will allow for USB-C devices like the 12-inch MacBook, smartphones, and tablets to connect to HDMI-enabled 4K displays and TVs (http://www.macrumors.com/guide/4k-5k-displays-buyers-guide-mac/) over a single cable, with no adapters or dongles required.

The new specification will lead to the release of simple HDMI to USB-C cables that support the full range of HDMI 1.4b features, including 3D, Ethernet, and CEC. Connecting an HDMI-enabled 4K display or TV to a 12-inch MacBook currently requires using Apple's $79 USB-C Digital AV Multiport Adapter (http://www.apple.com/shop/product/MJ1K2AM/A/usb-c-digital-av-multiport-adapter).

Thunderbolt remains the more popular I/O protocol for connecting 4K displays and TVs to Macs, since existing models are unable to drive 4K displays or TVs at 60Hz over HDMI by default. HDMI-enabled 4K displays and TVs connected to a 12-inch MacBook via adapter, for example, only support a 30Hz refresh rate.





In addition to the 12-inch MacBook, Apple is rumored to release updated MacBook Pro and MacBook Air models (http://www.macrumors.com/2016/08/29/new-macbook-pro-air-oct-amd-imacs-5k-display-lg/) featuring USB-C ports with Thunderbolt 3 (http://www.macrumors.com/2015/06/02/intel-thunderbolt-3-usb-c-displayport-1-2/) as early as October. Those notebooks would support HDMI to USB-C cables, providing Mac users with another option for connecting 4K displays and TVs.
