According to the new version of the "Guidelines for the Use of Trademarks and Logos" released, from now on, HDMI cable manufacturers are prohibited from using the version number logo when selling and advertising HDMI version 1.4 standard cables, and older cables should remove all labels, descriptions, packaging, etc. with the version number logo within one year.
