960H no video but 1080p works

[benjaminc 0]

Hello,

I recently accidentally changed video output format of one of my camera's PTZ settings.

Default settings was 1080p now it is 960H, the problem is now there's no video on screen, on the black screen it shows 960H on start up, others display 1080p. Cannot access PTZ menu.

 

Please tell me what can i do to get video back ?

Thank you.
