Vidikron VL-46 User Manual

• Save Settings: For each input and supported resolution, the DView lets you save image 

quality settings as presets that you can recall at a later time. You can create up to three 
presets – designated “Custom,” “ISF Day” and “ISF Night” – per input and resolution. 

You should save changes to any of the following settings to a preset; otherwise they will 
be lost when a new input source or resolution is selected:

• Brightness

• Contrast

• Color saturation

• Tint

• Sharpness

• Gamma

• Color temperature and white balance

To save image settings to a preset, select Save Settings from the ISF Calibration menu and 
select “Custom,“ “ISF Day” or “ISF Night.” 

White Balance: To remove any trace of color from the white areas of the projected image, 
choose White Balance from the Picture Adjust menu and press ENTER. 

• 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, 
decrease the Gain for that color.

• Offset: Use the Offset controls in the White Balance sub-menu to correct color imbalances 

in the dark areas of the image. A good way to do this is to use a test pattern consisting 
mostly of dark gray areas, such as a 30 IRE “window” pattern. If the gray areas contain 
traces of red, green or blue, decrease the Offset for that color.

Blue Enable: Blue Enable removes all red and green color information from the image, 
simulating a blue filter. You can use it instead of a blue filter when performing color and tint 
adjustments. 

Baud Rate: Select Baud Rate from the ISF Calibration menu to set the data transfer rate of the 
DView’s RS-232 SERVICE port. (This setting must match the data rate of the device connected 
to the RS-232 input.)

Serial Link: Select Serial Link from the ISF Calibration menu to configure the RS-232 Service 
port (see Figure 3-11) for normal operation (On) or for software upgrades (Off). 

Factory Reset: To reset all DView settings to their factory defaults, select Factory Reset from 
the ISF Calibration menu and press ENTER. This command is not undoable. Use it with 
caution!
