Sharpness: “Sharpness” is the amount of high-frequency detail in the image. To adjust 
sharpness, select Sharpness from the Picture menu and press ENTER. On your external 
test pattern source, select a pattern like the one shown in 
Figure 4-5. Adjust as needed, 
looking for white edges around the transitions from black to gray and differently-sized lines

Overscan: Image Overscan pushes the outside edge of the active picture area of the 
video signal out beyond the edge of the display area. 
Some television programs are produced based on the assumption that older television 
sets may not display the outer edges of the broadcast picture area. Over scan effectively 
trims away these inactive, outer edges and enlarges the remaining portion of the image to 
fill the display area.
Select from 1% to 10% of...

ISF Night - Display Color: Use the Display Color settings to change the characteristics 
of the output signal. These settings are global (independent of any particular input). 
Gain: Use the Gain controls to correct color imbalances in the bright areas of the 
image. A good way to do this is to use a test pattern consisting mostly of solid white 
areas, such as an 80 IRE “window” pattern. If the white areas contain traces of red, 
green or blue,...

Remote Control: The Remote Control menu shows you the primary and secondary 
infrared (IR) codes to which the VX-2i will respond. By default, both are set to 17. You can 
change these codes if either:
 Another device in the theater (a DVD player, for example) is responding to commands 
from the VX-2i remote control in ways that are unpredictable or undesirable.

HD Format: If for some reason the VX-2i does not properly detect the incoming signal 
format (color space) on the HD1 or HD2 inputs, specify it here (RGB or YUV). Otherwise, 
leave it set to Auto. 
Triggers: Select Triggers from the Service menu to configure the 12-volt trigger outputs. 
You can assign one or more trigger outputs to each aspect ratio. Those triggers are then 
activated by selecting that aspect ratio.

approximately 45 minutes prior to removing the lamp assembly for replacement.
2. Loosen the four rear Lamp Cover screws and remove the cover.
