Color Format
Inputs 1, 2, 3, 4, 5 and 6 are HDMI. By default the appropriate color space is automatically selected (“Auto” mode)
for standard-definition “Bt.601” or high-definition “Bt.709.” The “Auto” mode is generally best, but some upscaling
sources do not convert the color format to Bt.709 as they should and so “Bt.601” would be manually selected for
these if they are programmed to output HD formats. Bt.601 is used for SD/ED modes and Bt.709 is used for HD
modes. The command is:

Color and Hue
NOTE:
Set the display’s Color and Hue to their default values.
Use a test pattern generator, or test disc, test pattern to set Color and Hue if necessary. Normally not used if the
Color-Gamut is calibrated using the Radiance CMS system, unless the source has an error in its color decoder.

Y/C Delay
Adjust the horizontal Chroma timing in relation to Luma. It is suggested that you use a Y/C-delay calibration image
from a test pattern generator of test disc to calibrate the Y/C-delay. The C

and C
R
channels are adjusted
independently. The command is:

Input Size Controls
This menu has controls for the capture window for video input. There are settings for the input aspect ratio, size,
shift and masking.
Scale Bias
Scaling is normally on in order to adjust the source to exactly fit the output resolution. If the bias is set to “On”,
scaling is enabled unless the input and output resolution match exactly. If the scale bias is set to “Off” scaling is
disabled if the input and output resolutions are close. Scaling is disabled/enabled independently for horizontal and
vertical. When the bias is off there can be small borders on the edges of the image. If these areas have bad video
the output
Mask
command can be used to blank that portion of the image. The second page of on-screen status
information indicates whether scaling is active.

Input Sizing
Input sizing can be used to compensate for active image size differences between sources. Note: The input size
command does
not
affect the output size or position. Rather, it affects which input pixels are captured for
processing.
Use the
Crop TopLeft
command to select the top-left-most active input pixel. Use the
Crop BotRight
command
to select the bottom-right-most active pixel. For standard-definition sources you should set these controls so that
overscan is about 1.5% on all four sides. For digital high-definition sources, overscan may not be required. Cable
and Satellite Boxes may require more overscan. Select the scanline using the and arrows, and the pixel using
the and arrows. The command is:

Vertical Shift
The vertical shift is an easy way to move the image up and down without changing the
Input Sizing
settings. There
are 15 vertical settings that are shared between all input memories. Select the vertical shift setting and then the
shift value. The command is:
