No Picture-in-Picture Option Appears on Main Menu
If no PIP menu is available from the Main Menu, the PIP has not been detected by the
controller. Recycle power to the unit by disconnecting power and then reconnecting
power. If no PIP is detected again when the Main Menu is powered up again, call Z Micro-
systems’ Customer Support Department for assistance.
No Picture-in-Picture Display Image
There are a few scenarios which may cause the image on the PIP to be black. To elimi-
nate these concerns, follow the instructions below in the order they are presented:
1. Ensure the PIP is viewing something with contrast and shape and can be easily de-
tected under normal viewing conditions.
2. If the PIP is viewing something with these qualities, and should be easily detected, the
values associated with Contrast and Color Balance may require adjustment. To ensure
the Contrast and Color Balance values are not the cause of the black screen, set the
values to the factory default settings. See section titled, “PIP SoftMenus™”.
3. In some StarGate confi gurations, there are two inputs (RGB and Video channels).
Ensure the correct channel is chosen for the desired PIP.
4. If the black screen is for the RGB PIP, perform an Auto Adjust in the PIP submenu.
5. If no PIP image appears, call Z Microsystems’ Customer Support Department for as-
sistance.
