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.
• 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.

MARKER

• 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.
• Aspect Mat – darkens the background behind the markers for visibility
• Thickness – sets the width of the markers. Adjust as desired for best visibility

VIDEO

• 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 primary 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 upside-down.

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.

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 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.

SETTING
The Setting page provides a collection of system-level functions including On Screen Display (OSD), backlight, Ethernet port settings (IP Config), short cut keys (F1/F2), and Factory Reset.

• 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.

• Fan – Adjust the speed of the fan inside the monitor.

• Reset – Sets all menu items back to the way the unit ships from the factory.
