I wonder if it is possible and if there is an adapter or converter on the market for the following scenarios:
- VSX7000 - S-VIDEO output for HDMI- VSX7000 - VGA to HDMI output
Option 1: VGA to HDMI
Option 2: S-VIDEO for HDMI
Which of the above is compatible and functional with the VSX7000?
Whereas the VSX is past its end of life there could not be any testing doento confirm operation of any accessories with it.
I am sure there are multiple devices on the market for doing this function, I would suggest a internet search for devices that will fit your application.
Since the VSX is past its end of life, I would really recommend upgrading your system. Polycom has some upgrade promotions in progress, contact your Polycom reseller for details.
