There is no video on the monitor, but sound can be heard.


When powering on the unit for the first time, if not connected via component into a monitor there may be no picture visible. To correct this, the HDX video output must be changed. To change the video output without being able to see the screen, do the following:

  1. Verify the Eagle Eye Camera is plugged in to the Camera 1 input
  2. Power the HDX on
  3. Aim the remote control AT THE CAMERA.
  4. Press and hold the “Display” button, located in the top left corner of the remote control for approximately five seconds.
  5. The LCD screen on the remote will read “Display” and after approximately five seconds the display on the remote control will show an output.
    1. Composite
    2. S-Video
    3. VGA
    4. Component
    5. DVI
  6. Press the right arrow key. The remote control will read “Done” on the LCD screen

Polycom HDX systems, by default, output in component format except the HDX 6000, which outputs in HDMI. Refer to the chart below to see what signal formats each HDX will output.
