How to Connect the 4x1 Gefen TV Switcher
Connect the supplied cables from the HDTV HDMI sources into the Gefen1. TV Switcher inputs.
Connect the cable from your display (monitor or projector) into the HDMI out2. of the Gefen TV Switcher.
Plug the 5VDC power supply into the Gefen TV Switcher.3.
How to Control the Gefen TV Switcher
Use either the GTV4-IR remote control to toggle between sources or press the
input button on the rear of the unit.
EQ Button
By pressing the EQ button you allow the switcher to do a pre-emphasis on the
signal. This will help the video signal when long distances or low quality cable is
used.
Input Select Button
Pressing this button will toggle between the inputs in succession.
Automatic switching is done very easily. Whenever a connected device is
powered on, the 4x1 Gefen TV Switcher will switch to that input. Once that
device is powered down, the switcher will revert back to the previous input that
was active. The remote and input select button will always allow you to switch
manually. The remote will switch discretely to any input, while the input select
button will allow you to toggle between inputs.

wait for the LED's to flash in front of the unit. The LED's will flash the current IR
channel. (One flash for channel 1, two flashes for channel 2, etc.) Press the Input

finish. Using the guide below, make sure that the unit and remote are both set
to the same channel. If this does not work, please call Gefen's tech support for
