Menu Settings
Press MENU knob on the monitor and function menus will pop-up on the screen.
Rotate left or right to select an option. Then press the knob again to open the sub-menu.
When an arrow pointer appears in the menu, turn the Menu knob again to access the
item or press the knob to confirm a selection.
1. PICTURE
This page provides controls for typical picture adjustments.
Brightness – used to establish the correct black level in the picture. Default value is 50.
Contrast – establishes the range of dark to light areas in the picture. Default value is 50.
Saturation – sets the amount of color information in the picture. Default value is 50.
Tint – this function is designed to remove color errors in composite analog (NTSC, PAL)
signals. A better choice for component and digital signals is to use Color Temp / User to
establish the correct color tones. Tint control is only available when VIDEO input is se-
lected. Default value is 50.
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.
Default value is 128.
R/G/B Offset – Adjust the R/G/B Offset of the current Color Temperature from 0 to 511.
Default value is 256.

2. MARKER
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.
Marker Mat – darkens the background just behind the markers for visibility.
When Grid is turned on, Center, Aspect and Safety markers will not appear.
Thickness – sets the width of the markers. Adjust as desired for best visibility.

3. VIDEO
This page provides controls for picture size,
position and related functions including image
flip, image freeze and Zoom.
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 reso-
lution 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. 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 primary
colors. Useful for color analysis and troubleshooting.
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 upside-down.

4. CAMERA AUX
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.
False Color - a method to show each brightness in the picture with a different color. It
provides a quick way to tell if one part of a picture is too bright or too dark. Each color
represents 10% level change.
Exposure - creates “zebra” lines in the brightest areas of the picture. This mimics a feature
that is commonly found in broadcast camera viewfinders which provides a quick way to
check for over-exposure.
Exposure level - Use this setting to adjust the level that zebra lines will appear.
Histogram - is a graphical representation of the tonal distribution within a picture. This
mimics a feature commonly found in DSLR cameras.
This page offers settings to assist
with camera focus.
DSLR – Use the DSLR Preset option to reduce the visibility of on screen indicators shown
with popular DSLR cameras. The available options are: 5D2, 5D3. DSLR option is only avail-
able with HDMI input selected. Aspect and Marker settings are not available in this mode.

5. AUDIO
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 input,
Channels 1&2 will be used.
Level Meter – shows an on-screen bar graph of two audio channels (typically Left and Right)
from either an HDMI or SDI digital source.
Mute – Disables the headphone audio output when turned ON.
This Page is used to adjust volume, select audio
channel, enable level meter and mute.
6. SETTING
The Setting page provides a collection of system-level functions including On-
Screen Display (OSD), Ethernet port settings (IP Config), short cut key (F1 – F4),
and Factory Reset.

ML-702 Menu Settings
Language – sets on-screen messages to either English or Chinese.
OSD Timer – Adjusts the amount of time menus remain on screen.
Back light – Adjusts the brightness of the LCD backlight. This is different from the
“Brightness” control. Backlight is adjusted to compensate for room lighting without
upsetting Contrast and Brightness adjustments. It is generally best practice to set the
Back Light level before changing other picture settings.
DHCP – Enable or disable DHCP. When DHCP is on, the monitor will automatically get
an IP address from the network. The address will appear in the IP, Mask and Gateway
fields below. When DHCP is off, a Static address may be created manually using the menu
knob and arrow keys.
IP – Configures or displays IP address
Mask – Configures or displays Subnet Mask
Gateway – Configures or displays Gateway
F1 Conf. – Configuration for short cut key F1. Default is Peaking.
F2 Conf. – Configuration for short cut key F2. Default is Level Meter.
F3 Conf. – Configuration for short cut key F2. Default is Level Meter.
F4 Conf. – Configuration for short cut key F2. Default is Level Meter.
Reset – Sets all menu items back to the way the unit ships from the factory.

Peaking is off.
4. Picture is “stuck” on screen:
Access the Video menu page and check that IMAGE FREEZE is off.
5. Solving Other problems:
The monitor can be reset to Factory original settings. This is sometimes useful to
eliminate the possibility that an improperly set menu item is interfering with the op-
eration. To reset the monitor, access the SETTING menu page, press the Menu knob
then rotate left or right to select Reset. Press the knob once then rotate the knob to
cause the unit to reset.
