HP High-Definition LCD TV Service Manual 19
HDMI devices are usually HDTV receivers or DVD players. They connect using a single cable with a multipin
connector. These TVs have three HDMI ports, so up to three HDMI devices can be connected at the same time.
The HDMI 1 port additionally supports separate HDMI audio. This configuration requires a DVI-to-HDMI converter that
connects a DVI cable from optional DVI equipment and connects to the HDMI audio in ports using a pair of stereo
audio connectors. The white port is for the left channel and the red port is for the right channel.
RS-232 Port
The RS-232 connector works like a serial port on a PC and is also sometimes called a serial port. It is used to receive
digital instructions from control applications running on a computer.
