Hi,
Are you using the default cable setup?
You probably need to change the screen output for the OSD-menu. This is documented in the C90 Administrator Guide
An outline for you:
Moving the OSD using the remote control
If the main monitor is connected to DVI-I 2 video output you
must run the following shortcut or key sequence on the remote
control.
• Disconnect * # * # 0 X #
X=1 (HDMI 1) X=2 (DVI–I 2)
X=3 (HDMI 3) X=4 (DVI–I 4)
You can also move the OSD in the CLI and by logging on to the codec through HTTP
