New Group Series 700 Codec Black Image

I went throught the setup wizard, I selected 1920x1080.  When the codec boots it displays the Polycom startup screen and goes to a black image.  On the front of the codec LED it reads 1920x1080 VGA?"   It's not on the IP network yet I need to get the MAC address off of it for my network engineer.  Any thoughts on why it's not displaying a image?  Id there a way to change the resolution with the handheld remote?

The MAC can be extracted from the Serial Number.   


Serial Number: 8213050FD69BCV

MAC:   00:E0:DB:0F:D6:9B


As for the Black Video, it sounds like the wrong resolution...   Were you plugged in with VGA or HDMI ?


Good luck,

Re: New Group Series 700 Codec Black Image

The first time I turned on the codec I was connect to VGA.  It went throught the wizard, it provided me an option to select a resolution I selected 1920x1080.  I think this is was messed it up.  Now I am plugged into the HDMI, I see the Polycom splash screen at boot and whenit''s done I only see a black image.  1920x1080 / VGA is on the led on the front of the codec.  maybe I should perform a factory reset and start over.  I thought there might be a way to change the resolution type i.e. VGA to HDMI via the handheld remote or should it auto detect?

If you have not selected the input you have the source on you will not get it.  I was confused on where you have the VGA plugged into.  If it is not the camera 1 input it will not send it.  You can, in the configuration menus, select a different input as the main camera, and it has to be defined as People.  You can not select as the main camera a content source.


The monitor output will scale inputs to the right resolution.
