I was saying that I tested only the video server configuration mode:
I press the menu (on the videoserver button)
I choosed advanced then display,
then I went to dwell time but I wasn't able to select a different value than 2. I was able to make any other change in the manu.
What I didn't try was to use the AVC760 physical buttons because it is installed in the basement and the monitor (TV) is in first floor. I cannot see the monitor while I am pressing the button. I cannot move the monitor to the basement because the stairs are not completed yet - so I will try the physical buttons with the aid of a friend and a phone line. I will watch the monitor and say him what button to press.
Best regards,
Alex
