matching is used if needed. The command is:

Color Format
Sets the outputs color format. It should be set to Auto except to correct for a color format error in the display.
Normally Bt.601 is use for SD/ED modes and Bt.709 is used for HD modes. Use the Auto format unless there is an
issue that requires a manual selection. The command is:
MENU → Output → Styles → [Style] → HDMI Format → Color Format → (Auto, Bt.601, Bt.709)
Dither
Some fixed pixel displays show contouring on images that have gradients because the physical pixel depth of each
pixel is limited. The dither control can be used to enhance the resolution of the display and reduce contouring.
Dither position sets the bit size of the pixel for dithering. Orientation controls the frame-to-frame randomization
and can be fixed of dynamic. Masking can be turned on to clear the lowest bits after the dither addition. The

Mask
Allows you to “blank” the edges of the video image on the output without changing its position or scaling. This is
useful to blank bad pixel data from the source that shows on screen, when you want to keep the “pixel perfect”
setup (i.e. no scaling). The command is:
MENU → Output → Styles → [Styles] → Mask/Shrink → Mask
Shrink
Adjust the image size to fit inside a screen masking system. This command is useful for rear-screen and flat-panel
displays when the manufacturer uses too much “overscan”. The command is:

Keystone
Adjust for a projector vertical placement offset. Note: Use only if the projector does not have enough optical
keystone adjustment. The command is:
MENU → Output → Styles → [Styles] → Mask/Shrink → Keystone
Gray Level
Sets the gray level of borders created by the shrink or output mask commands. The gray level is adjustable from
black to white in sixteen steps. The command is:

Screen Aspect Ratio
Select the screen aspect ratio. The screen aspect ratio range is 1.10 to 2.50 and is entered in units of hundredths
(e.g. 16:9 is entered as 178). If you have a normal fixed aspect display, select the “Single output aspect” which is
the default setting. If you have a movable anamorphic lens or a projector with programmable lens-shift and focus
that you are using, select “Output aspect per input aspect.”
For the “Output aspect per input aspect” mode, there is a special case when you use NLS. When the input aspect
is 4.3+NLS the output aspect assigned to the 16:9 entry is used. When the input aspect is LBOX+NLS, 16:9+NLS,
or 1.85+NLS the output aspect assigned to the 2.35 entry is used. The command is:
MENU 0 6 (Single output aspect, Output aspect per input aspect)
or MENU → Output → Styles → [Style] → Aspect Ratio → (Single output aspect, Output aspect
per input aspect)
