Figure 6: First Video Timing Information Display 

 

An  example  of  the  LCD  displaying  the  video  timing  information  is  shown  in  Figure  6.    The 
information  indicates  that  the  left  channel  is  currently  receiving  a  1280x1024  resolution  video 
signal operating at 60 Hz.  In addition, the letter “D” at the end of the text string indicates that the 
signal is digital.  In the case of an analog signal, the letter “A” will be displayed in its stead (Figure 
7

).  The “Mono Clone” message on the right channel indicates that no video signal was detected 

on the right eye.  The AVCU is currently repeating the left video signal to the right eye. 

 
 

 

Figure 7: Second Video Timing Information Display 
 

If a stereoscopic setup is being used, timing information for both eyes will be displayed. 
 
Figure 8 shows and example of the video detection banner.  In the example, a DVI signal is detect 
on the left channel, as indicated by the “x”. 

 

 
 

Figure 8: Video Detection Display 

 

The monitor output settings for the two monitor outs can be viewed by pressing the Enter button 
until the corresponding banner  is displayed.  An example of the monitor out settings banner is 
shown in Figure 9. 

 

 

 

 
Figure 9: Monitor Out Settings Display 

 

The banner is currently indicating the monitor out setting in the case of a stereoscopic setup.  The 
VGA monitor out will repeat the left eye, and the DVI monitor out will also repeat the left eye. 

 
ADJUSTING BRIGHTNESS 

On standard AVCU products (AVCU-S), pressing the +/- buttons from the main menu adjusts the 
brightness of the display.  On wide FOV products (AVCU-W) the brightness controls are disabled.  
The +/- buttons will not do anything.
