As high-definition TVs gain larger slices of market share, so do the digital technologies that provide the TVs with their sharper images. One such technology is HDMI. Consumer electronics and computer manufacturers have jumped on the HDMI bandwagon, offering many new pieces of hardware that support the format. Unfortunately, some HDTVs only have a single HDMI input -- leaving people with multiple HDMI-enabled devices in the lurch, at least at first glance. However, you can use a device called an HDMI switcher to connect two HDMI devices to a TV with one HDMI port.
Situate the HDMI switch in a central location, near your HDTV and the two devices you'd like to connect to it. If the HDMI switcher needs to be plugged in, take the unit's power cord's length into account as well.
Plug HDMI cables into the "HDMI Out" ports of the two devices you'd like to connect to the HDTV. Use a separate cord for each device -- do not connect the two devices to each other with the same cable.
Connect the other end of the two HDMI cords into the "Input" ports on the HDMI switcher.
Connect a third HDMI cord to the switcher, this time in the "HDMI Out" port rather than an input. Connect the other end of the cable to the HDMI input on the back of the HDTV.
Plug in the HDMI switcher, if necessary.
Turn on your HDTV.
Change the HDTV's input options to show the HDMI signal.
Turn on the HDMI device you'd like to use.
Push the button on the switcher or the switcher's controller that corresponds to the device. For example, if you connected a DVD player to the first HDMI port on the switcher, push the button that activates the signal from port one. Push the button for port two to show the signal from the other device.
Purchase an HDMI switcher with more inputs if you have more than two HDMI devices to connect.
