This article relates to the Cisco TelePresence System Codec C90 and Cisco TelePresence System Codec C60 products.
Q. When using VGA (640*480) analog input on the TANDBERG Codec I see distorted video and double images, why?
A. This answer is valid for the following products:
TANDBERG Codec C20
TANDBERG Codec C60
TANDBERG Codec C90
This is is currently a known issue in the first version of the TC software. A workaround is to increase the resolution or use the digital input (DVI-D or HDMI).
To increase the resolution, open the Home menu on screen and go to: Settings > Administrator settings > Advanced configuration > Video > Output and set the Resolution for the relevant video output.
