How to connect the Gefen TV Signal Generator
1. Connect the HDMI OUT of the Gefen Signal Generator to the HDMI of your
HDMI display or device.
2. Plug the 5V power supply into the Gefen TV Signal Generator.
3. Turn on the display fi rst.
4. Turn on the Gefen TV Signal Generator second.
You may need to press the OVERSCAN button if the signal from the Gefen TV
Signal Generator does not fi ll the entire screen.
If you are not receiving a picture, check your power supply. Make sure the Gefen
TV Signal Generator is plugged in and that the unit is turned on. If your display
has more than one HDMI port, make sure that your display is set up to receive
signals from that input. If you’re testing HDMI, make sure that the Output Signal
Selector is set to HDMI.
If you are still unable to receive a picture, it is possible that the current output
timing is not supported by your monitor. The current timing (resolution and
refresh rate) are displayed in the LCD window on the unit. Use the Timing
Selector UP or DOWN buttons to select a different timing. See chart on page 8.
Once you have established a timing that is accepted by your display, you can
select from a wide array of video test patterns by using the Pattern Selector UP
or DOWN buttons (see table beginning on page 9).
Checking stereo or multi-channel audio capability

your A/V receiver.
3. Connect the HDMI OUT from the A/V receiver to the HDMI IN of your display.
