Troubleshooting:

1. Power
   1. If the device is not receiving any power, be sure to try a different outlet or surge protector. If there is still none, contact support, as the power adapter or unit may require replacement.

1. Video
   1. If one or more sources are not providing video, while others still appear to function as intended, confirm the functionality of the cable going into the HDMI IN from that device.
   2. If one or more outputs are not providing video, while others still appear to function as intended, confirm the functionality of the cable going into the HDMI IN of that display.
   3. If no inputs are showing up on any of the outputs, confirm that all displays are showing the correct input (I.E. Input - HDMI 1, 2, 3, 4). Confirm whether or not the unit is receiving power. If there is no power, refer to troubleshooting step 1. If there is power, the unit may require replacement.
   4. If video is being displayed, but they are jumbled or are in an incorrect order, readjust the output HDMI cables located on the back of the unit until the picture is coherent.

1. Audio
   1. If no audio is being provided to one or more displays while others work, confirm the functionality of the associated, non-working audio display's HDMI cable. 

1. Firmware
   1. If the website has a new firmware update for the unit, you can update it through the firmware port on the  rear of the unit.
