IMPORTANT NOTES: This RCA cable is not compatible with PC / laptop / PS4 / XBOX / DVD. Before purchasing, please ensure that both devices have signal encoding and decoding functions. For more information, please refer to your device's user manual. HDMI is a digital signal, and RCA is an analog signal; this cable does not convert the signal. The devices themselves need to convert the signal. Please ensure that both devices support encoding and decoding. If the devices do not support encoding and decoding, please purchase an adapter separately. This HDMI to 3RCA cable is used to transmit signals from a player to a TV. It does not support converting signals from a computer, DVD player, PS3, or set-top box directly to a TV. It is also not possible to use an HDTV adapter to transmit this line to the TV. It functions as a signal transmitter, not a signal converter. This is a one-way HDMI to RCA transmission cable; RCA to HDMI cannot be used, meaning the display device (TV or screen) is the RCA end. HDMI to RCA cable for high-definition DVD players, HDTV receivers, TVs, projectors, A/V receivers, and other HDMI-equipped devices.
