At the maximum level setting (the clockwise limit of this control), the interface outputs video at 1.45 volts p-p.

Select a setting in the boost range (0.7 volts and above), to compensate for the decrease in signal level that occurs when the signal passes through long cables.

Set the boost at 100% (the maximum level) for cable lengths over 500 feet for all computer signals of 15 kHz to 150 kHz.

B

Peaking (Peak) control — Peaking affects the sharpness of a

 

picture. Increased peaking can compensate for detail (mid- and

 

high-frequency) loss from low bandwidth system components

 

or capacitance in long cables. The minimum setting (at the

 

counterclockwise limit) provides no peaking. The maximum

 

setting (at the clockwise limit) provides 100% peaking. Adjust

 

this control while viewing the displayed image to obtain the

 

optimum picture sharpness.

Centering controls

 

Many projectors store centering information in their own

 

memories based on signal frequency. When a projector displays

 

video from different input sources that have the same frequency,

 

one source’s images may not be centered. Using the interface’s

 

centering controls eliminates that problem.

C

Vertical centering ({) — While viewing the displayed image,

 

rotate this control to move the image up or down on the screen.

 

During centering adjustment, the LCD displays V-SHIFT, and

 

it indicates the vertical shift minimum or maximum limit when

 

the centering limit has been reached. See the notes below item

4.

D

Horizontal centering ([) — While viewing the displayed

 

image, rotate this control to move the image to the right or left

 

on the screen. During centering adjustment, the LCD displays

 

H-SHIFT, and it indicates the horizontal shift minimum or

 

maximum limit when the centering limit has been reached.

 

N DDSP disables the interface’s vertical and horizontal

 

centering controls. If DIP switch 1 (DDSP) is set to On

 

and either centering control is rotated, the LCD displays

 

N/A DDSP ON.

 

To use the display’s centering controls rather than the

 

interface’s controls, set the DDSP DIP switch to On.
