HDMI 1.4 supports work at the maximum distance of about 35 m, while HDMI 2.0 only supports about 10 m. HDMI 2.0 is designed for higher bandwidth than HDMI 1.4. Both can deliver 4K video, but HDMI 2.0 can transfer up to 18Gbps whereas HDMI 1.4 can only transfer up to 10.2Gbps. That extra bandwidth allows HDMI 2.0 to deliver a few extra features that might have seemed unnecessary just a few years ago.
