The HDMI specification does not limit cables to any particular length, but instead sets performance criteria based on maintaining adequate signal strength. Therefore, cable length is not determined by the HDMI specification, but by the design and manufacturing quality of the cable.
HDMI 2.0, which is backwards compatible with earlier versions of the HDMI specifications, significantly increases bandwidth up to 18Gbps and adds key enhancements to support continuing market requirements for enhancing the consumer video and audio experience.
LAS VEGAS — At its press presentation at the 2015 International CES, Hisense has shown off the Vidaa Max, a short-throw laser projector that can beam a 100-inch image from a distance of only 2 feet.
The projector — also called the 100P1 if you don’t like Vidaa Max — doesn’t require a dedicated screen, meaning the console can be moved easily from room to room, unlike other similar products like the LG Hecto Laster TV.
