HDMI extension cable With this cable, you can increase the length of the HDMI cable up to 10 cm. On the other hand, CCTV and projector installers in schools, organizations and organizations cannot easily replace the HDMI cable due to the long length of the HDMI cable passing through the ducts and hidden pipes due to damage and tearing of the HDMI cable socket, or Even in terms of cost, it may not be affordable, so Digico recommends a short male and female HDMI cable to prevent this damage. Using the HDMI cable, you connect this short cable to the TV or video projector or other devices, and in case of failure, just replace the short HDMI cable and avoid a big problem.
