A.This cable is only designed to connect and transfer signals from HDMI source output to VGA port display devices, reverse connection is unworkable.
B.It functions as a signal transmitter, but not a signal converter. As HDMI carries digital signals while VGA / RCA carries analog signals.

If both input / output device do not support signal conversion, a signal conversion box is required.
