NOTE: Even though HDMI cables support Hot Plug Detection, improper usage might result in resetting / restarting both devices, or even may cause damage to the devices. Therefore, we do not suggest Hot Plug action for any HDMI cables. Please make sure both input and output devices are off when plugging or unplugging HDMI cables. HDMI to VGA / RCA cable is designed to connect and transfer signals from HDMI port to VGA / RCA port. This cable functions as a signal transmitter, but NOT a signal converter. As HDMI carries digital signals while VGA / RCA carries analog signals. In order for these two formats of signal to communicate with each other, both input and output devices needs to support the signal conversion function (code and decode) please kindly check with your user manual. If both input / output device do not support signal conversion, a signal conversion box is required.
