Sharpness – adds synthetic “detail” to the image. HD images should require very little
added sharpness. Default value is 0.
Color Temp – this setting provides three different presets for white balance approximating different common color “temperatures”. USER allows for custom calibration by
adjusting Gains and Offsets as desired:
R/G/B Gain – Adjust the R/G/B Gain of the current Color Temperature from 0 to 255.

2. MARKER
ML-503 / Menu Settings
This page offers controls for setting
various on-screen markers.
Center Marker – places a “+” mark in the exact center of the display.
(Useful for checking camera or graphics positioning.)
Aspect Marker – places borders on screen representing various typical video and
cinema aspect ratios. This does not change the displayed aspect ratio. (That setting is in
the Video menu.)
Safety Marker – places a border around the edge of the screen to be used as a guide
during video production.
Marker Color – the Center, Aspect and Screen marker colors can be changed here
Grid – On-screen grid lines are useful when matching camera shots or during editing.
When Grid is turned on, Center, Aspect and Safety markers will not appear.

3. VIDEO
This page offers controls for setting
various on-screen markers.
Scan – Selects various display methods. When Aspect is selected, the item below this
one can adjust the aspect ratio of the displayed image.
Aspect – Allows changing the aspect ratio (shape) of the picture to match the
incoming video. Settings are available for various video and cinema styles.
Pix-to-pix – displays the incoming video with a 1:1 pixel match. This provides the
clearest resolution but usually changes the size of the image. This turns off up/down
“scaling”. For example: a video input that has fewer pixels than the LCD display will
appear to shrink while a video input that has more pixels will appear to expand. This
can be useful to determine where artifacts are occurring by eliminating monitor scaling. When this mode is on, Aspect, Display Scan, Zoom and Markers will be off.
Zoom – expands the picture digitally. It is normal for picture quality to become less
sharp as the picture is expanded. When this mode is on, Aspect, Display Scan and
Markers will be off.
Display Scan – Provides additional methods for viewing images
Full scan – Uses all pixels available in the display. This may not match the aspect ratio
of the incoming signal.
Overscan – enlarge the image slightly to conceal image edges.
Underscan – shrinks the image slightly to allow viewing image edges
Check Field – displays the picture in monochrome (black & white) or in individual prima-
ry colors. Useful for color analysis and trouble shooting.
Freeze – holds the current picture on screen.
Image Flip – the picture can be reversed top to bottom, left to right or both. This can be
a useful tool when viewing images shot through mirrors or from cameras mounted up-
8
side-down.

4. CAMERA AUX
This page offers settings to assist
with camera focus.
Peaking - adds a colored edge to picture details making it easy to identify which areas
are in sharpest focus.
This is a useful tool to use during camera lens adjustments.
Peaking color – Peaking colors may be changed as needed for best visibility. Available
colors: red, green, blue, white, black. The default color is red.
Peaking level - Use this setting to adjust amount of edge peaking to suit user preference. Default level is 50.
5. AUDIO
This Page is used to adjust volume, audio
channel selection, on-screen level meter and
headphone mute.
Volume – controls the Headphone volume. Headphone volume can also be adjusted
easily by using the up/down arrow keys when the menus are not on screen. Default
volume setting is 50.
Audio channel – With SDI input, channel pairs may be selected from 1-16. With HDMI
