User Manual Data Video Projector 22
Question mark: 
A question mark in a box will appear if
the projector can’t recognize the mode of the data input
source.
Even if you select a standard VESA mode on your system this can 
happen, because some device drivers of the graphic cards in the PC 
using timing parameters which differ from the parameters given out 
from the VESA organization.
As a result of this, the projector may detect a wrong predefined data 
mode or switches to a User mode, so you may see only a part of the 
whole picture.
To correct this situation you must select manually a data Mode in the 
Picture menu which should match the mode you’ve selected on the PC. 
If there is no matching mode you must select a User mode.
In a User mode you can manually select the Resolution which is 
normally not choosable.
It may be necessary to correct the Horizontal and Vertical Position and 
the Tracking and Sync values in the Picture menu. These values will be 
stored so the mode can be recognized the next time.
If you’ve accidently misadjusted the values of a standard predefined 
data mode, you can reset them by selecting Reset Data Modes in the 
Advanced Setup menu. The settings of a User mode won’t be affected 
by this action.
