These advantage drive a lot of people willing to try this new technology, but inside risk not everybody know. Some people found that there is no signal after installation, today we are talking about some reason cause this problem, to help you find the reason, to help you find a better quality HDMI AOC for your project.

 1. Wrong direction, this is fiber optical HDMI cable, HDMI signal is sending by lighting, it is a uni-direction product, so you have to put Source to PC/STB/DVD, and Display side connect to TV/Screen/Project etc.

2. Cable broken, since this inside cable is fiber optical, no matter plastic fiber optical or glass fiber optical, there is a bending radium, so please read your cable manual before installation, to avoid any cable broken or wrong bending radium, Smartavlink’s HDMI AOC can take a knot , it is very small bending radium on the marketing to avoid a not potential risk.
