HD LEEZA VIDEO PROCESSING FUNCTIONS
Brightness and Contrast:
Use these controls to set the black level (brightness) and white level (contrast) of any video input. It's
helpful to have a calibration DVD on hand to supply the appropriate test patterns. You can also find
grayscale patterns under Menu selection #7.
Saturation:
Set color saturation with this menu. It's best to have a color bar test pattern and a standard blue filter to
make this adjustment. You can find this pattern under Menu selection #7.
Red and Blue Saturation:
RS232 commands are available to set blue and red saturation, to allow you to fine-tune red and blue levels
(adjustments are not available through the IR Remote Control OSD Menus). Use a color bar test pattern and
a blue filter to set correctly. To set blue_saturation, use u<space>{0,1}<space>#. If the number following u
is 0, blue_saturation will be set to a positive number; if the number following u is 1, blue_saturation will be
set to a negative number. The legal range is -10 through 10. To set red_saturation, use
e<space>{0,1}<space>#. Other properties are as in the blue_sat case.
Edge Enhancement:
This function controls edge sharpness (peaking). Use it for lower-resolution sources such as VHS tapes
and cable TV programs. Higher-resolution sources typically do not need edge enhancement.
Picture Aspect Ratio:
Your video source may send standard (4:3) aspect ratio or widescreen (16:9) aspect ratio pictures to HD
Leeza. Standard-size images are typical from VHS tapes and regular TV programs, while widescreen
images are more common with DVD players.
To set the correct input aspect ratio, press the AR-IN button. You will see a list of six input aspect ratio
choices and one custom setting. For standard 4:3 program sources, use the buttons to move to and select
1.33 input. For widescreen DVDs, you can use any of the other choices. Check each DVD's packaging to
see what its actual aspect ratio is. Typically, 1.78 or 1.85 will work for widescreen DVDs.
Picture Gamma:
You can adjust the gamma for any input in .05 steps from 1.0 to 1.5. Use a grayscale step pattern from
Menu selection #7 to make this adjustment.
Setting Horizontal and Vertical Input Offset:
•
Full-scale (three-digit) control over H and V offsets is available in the PA menu for
versions 5.5.55 and higher (more recent) of the firmware.
•
Please use the horizontal and vertical offsets in the Picture Adjust menu very carefully – use
your display’s adjustments or HD Leeza’s System Adjust to match HD Leeza’s output to your
display, not Picture Adjust.
•
Horizontal centering is maintained for 1.33 Input AR when horizontal size is not default.
