Operation, cont’d
IN1404XT Video Scaler and Switcher • Operation 3-18
The VTR001 CM that receives the TP output can receive RGsB signals from
the scaler. However, the red, green, and blue video signals’ black levels are not
clamped to a 0V reference, as for RGBHV or RGBS. For most displays, this is
not
a problem. On some displays (such as some LCD displays) however, the
black levels of the red, green, and blue signals may change as the average
picture level changes, resulting in an unacceptable image.
Blue Screen screen
The Blue Screen screen turns the blue screen feature on and off. When on, the blue
screen feature is helpful in the setup of the size and position adjustments on the
display. In the blue only mode, a solid blue field is passed to the display.
The video and input screen settings have no affect on the blue screen. Once the
output settings have been adjusted, turn the blue screen off and then you can
adjust the video and input settings.
Use the Menu button to highlight “ON” and press the Enter (and save) button to
turn on the blue screen feature. Use the button to highlight “OFF” and press the
Enter
(and save) button to turn the blue screen feature off and return to the normal
video output.
