This bulletin was created to inform you of an issue that can occur when a PC is connected to a
PowerLite 7800p / 7850p 15 pin VGA “Computer” port with the input mode set to “RGB-Video.”
The image is displayed, but all 4 sides are clipped. No amount of adjustments on the PC or
the projector settings can fix the screen.
Reason:
The PowerLite 7800p/7850p has 2 video input signal modes for the 15 pin VGA “Computer”
connector. The two signal modes are
the 15 pin VGA connector, be sure that you have selected “Analog-RGB” as the signal mode.
Refer to page 72 of the PL-7800p User’s Guide or page 133 of the PL-7850p User’s Guide for
more information on customizing projector features.
If you have selected “RGB-Video” you will see clipping on all four sides of the displayed image.
There are 2 ways to change the input signal mode. The easiest method is to repeatedly press
the “Comp” button on the remote control until “Computer (Analog-RGB)” is displayed in the
upper right corner. To toggle the input signal mode you must press the button while the source
message is still displayed in the upper right corner. This will correct the clipping issue.
Notes:
1. If you do not see a message in the upper right corner go to the projector’s menu, and
navigate to the “Setting” menu and set “Message” to “On.”
2. Do not use the projector’s control panel with this method.

The second method is to use the projector’s menus. Bring up the projector’s menu by pressing
the “Menu” button on the projector’s control panel, or on the remote control. Then using the
arrow buttons, navigate to the “Setting” menu, press enter, and arrow down to “Computer
Input” and press enter. Select “Analog-RGB” and press enter. When you exit the menu
system, the displayed image will appear without any clipping.
The BNC Input connector also has 4 input signal modes including the two signal modes of
“Analog-RGB” and “RGB-Video.” To connect a PC to the BNC connector, be sure that you
have selected “Analog-RGB” just like the 15 pin VGA “Computer” connector. You can use the
same methods described above for changing the BNC Input signal modes, just substitute
“BNC” for “Computer.”
Note: Connection of a PC to the BNC Input is seldom used, as it requires a special cable.
