MENU SETTINGS

Press the 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 to confirm a selection.

1. PICTURE
   • Brightness – used to establish the correct black level in the picture. The default value is 50.
   • Contrast – establishes the range of dark to light areas in the picture. The default value is 50.
   • Saturation – sets the amount of color information in the picture. The default value is 50.
   • Sharpness – adds synthetic “detail” to the image. HD images should require very little added sharpness. The default value is 0.
   • RGB Range – choose the RGB range of the HDMI input between Full or Limited. This choice only applies to HDMI inputs. When viewing HD video based on television standards such as REC 709, Limited is the correct choice. When working with computer graphics Full may provide a wider range of color.
   • HDMI EDID – select the HDMI EDID from between 4K and 2K. This item enables the PC, set-top box, or other device to configure itself for the best video quality. This choice only applies to HDMI inputs.
   • Camera Log – use this item to choose one of the camera Log modes between Def log, and User log.
   • Def. Log – Default (preset) Log modes. When viewing material from a camera that has a Log gamma curve applied, the pictures will not appear normal unless the matching Log mode is selected.
   • User Log – use this item to install and apply a “User LUT” (Look Up Table) instead of one of the Default Logs
   • To install a User Log “LUT”:
   • Check that the User LUT name ends with “.cube”. (This is common).
   • Two types are accepted: 17×17×17 or 33×33×33, Data order is BGR, and Table order is BGR.
   1. Rename the LUT file as User1.cube up to User6.cube. (6 files may be stored in the monitor)
   2. Copy the user LUT onto a formatted USB drive.
   3. Insert the USB drive into the USB port on the rear panel of the monitor. The User LUT will be imported into the monitor automatically. If the User LUT does not load automatically, a message will appear with “no user data” or offer a choice to manually load the User LUT. If “no user data” appears please check that the file meets all the requirements noted above.
   • Gamma – Gamma correction applies a non-linear “curve” to the displayed range between dark and light. Historically, 2.4 is chosen because it is the inverse of a standard camera Gamma of 0.45 producing a roughly “linear” match. Today, different camera Gamma values are often applied for creative purposes so a different monitor Gamma may be chosen for viewing. It is best practice that, once set, Gamma is not changed during a production shoot or an editing or color correction session. Gamma OFF would be used only during testing, calibration, or when using an external video processor. The gamma range is 1.8 to 2.8. Gamma is not available if S-Log or User LUT has been selected.
   • HDR – HDR “High Dynamic Range” is used to properly view video that has been enhanced through one of the common HDR processes. Three SMPTE ST 2084 standard settings are available. These are calibrated to 300, 1000, and 10,000 NIT displays. (The only 10,000 NIT displays are projectors). A fourth setting is available, HLG, which is commonly used for broadcast. When HDR is activated, the display can reproduce a greater dynamic range of luminosity. The best results will be obtained when the monitor setting matches the HDR emphasis that was applied to the video material. Using HDR mode with non-HDR material typically looks very unnatural.
   • Backlight – adjusts the brightness of the LCD backlight. This is different from the “Brightness” control. The 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.
   • Color Temp – this setting provides four different presets for white balance approximating different common color “temperatures”. The most common is 6500K. USER allows for custom calibration by adjusting Gains and Offsets. as desired:
   • R/G/B Gain – adjust the Red, Green, or Blue Gain of the current Color Temperature from 0 to 255. Default value: 128.
   • R/G/B Offset – adjust the Red, Green, or Blue Offset of the current Color Temperature from 0 to 511. Default value: 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 the screen representing various typical video and cinema aspect ratios. This does not change the displayed aspect ratio. That setting is in the Display 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.
   • Aspect Mat – darken the background just behind the markers.
   • Thickness – sets the width of the markers.
3. DISPLAY
   • This page provides controls for the picture size, Zoom, check field, image freeze, and Overscan.
   • Scan – Adjust the scan mode among [Aspect], [Pixel To Pixel], [Zoom].
   • 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 will appear to shrink while a video input that has more pixels will appear to expand. In either case, the image is shown in its “true” resolution.
   • Zoom – expands the picture digitally. It is normal for picture quality to degrade as the picture is expanded.
   • Overscan – enlarge the image slightly to reduce image edge distortion.
   • H/V delay – shifts the picture vertically and horizontally to allow viewing the vertical and horizontal “blanking areas” which contain the HANC and VANC ancillary data.
   • Check Field – displays the picture in monochrome (black & white) or in individual primary colors. Useful for color analysis and troubleshooting.
   • Zoom – expands the picture digitally. It is normal for picture quality to degrade as the picture is expanded.
   • Image Freeze – holds the current picture on the 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. WAVE
   • The Wave page offers adjustments for the on-screen Waveform monitor, Vector scope displays, and video assist functions like focus peaking, exposure “zebras”, and false color luminance level check.
   • Full Mode – The following analysis functions are full-sized and fill the entire display. In this mode, the Video is not displayed
   • Waveform – Selecting Waveform instead of Full Mode places a compact version of the Waveform Monitor function as an overlay at the bottom of the display. Overlays are limited to Y, YCbCr, and RGB presentations.
   • Y – a graphic representation of the brightness from left to right across the picture. This is the most common setting and is particularly useful for adjusting lenses and lighting.
   • YCbCr – a graphic representation of the Luminance plus the color components in the video signal. Useful for equipment adjustment and confirming proper operation.
   • RGB – a graphic representation of the three primary color components of the video picture. Useful for making equipment adjustments.
   • Audio – shows an on-screen bar graph of audio channels (typically Left and Right) from either an HDMI or SDI digital source.
   • Vector – a graphic representation of the colors in a picture. Brightness levels are not shown. The vector display is used with color charts or test signals.
   • Transparency – change the visibility of the chart on the screen. Adjust as desired for best visibility.
   • Peaking – adds a colored edge to picture details making it easy to identify which areas are in sharpest focus.
   • Peaking Color – Select one of the peaking colors: Red, Green Blue, White, Black.
   • Peaking Level – adjust the amount of peaking color. The range is 1 – 100.
   • 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. There are 10 colors representing 10% steps. The default mode matches the False Color feature in other Marshall monitors. Additional modes are provided to match color modes used by RED and ARRI.
   • False Color Table – Places a color guide on the screen. This guide shows what level from 0 – 100% each color represents.
   • 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 overexposure.
   • Exposure Level – to adjust the level of peaking. The exposure level can be set to [50]-[100].
   • Histogram – use this item to activate or deactivate the histogram.
   • Y – a graphical representation of the tonal distribution within a picture.
   • RGB – a graphic representation of the three primary color components of the video picture. Useful for making equipment adjustments.
   • COLOR – a graphical representation of the mixed RGB distribution within a picture.
   • 4 Bar Display – a graphical representation of the peak value of YRGB.
   • Time Code – The Time Code display supports embedded Longitudinal time code (LTC) and Vertical interval time code (VITC) types. Time Code display is only available with SDI input. HDMI does not have a time code.
5. AUDIO
   • This Page is used to adjust the volume, audio channel, lever meter, and mute.
   • Volume – controls the Headphone volume. Volume can also be controlled by turning the menu knob when menus are not on screen. The default level is 50.
   • Level Meter – shows an on-screen bar graph of audio channels (typically Left and Right) from either an HDMI or SDI digital source.
   • Audio Vector – this is the traditional “oscilloscope” pattern comparing left and right audio channels. When a tone is present, a straight line will appear if both channels are “in-phase”. A circle will appear if the channels are 180 degrees “out of phase” or reverse polarity. With normal audio, there will be a pattern of constantly moving lines.
   • Vector CH – With SDI input, channel pairs may be selected from 1 – 16. With HDMI input, channels 1 & 2 will be used.
   • Audio CH – With SDI input, channel pairs may be selected from 1 – 16. With HDMI input, channels 1 & 2 will be used. This setting selects what appears in the audio bar display and what is heard in the headphone output.
6. REMOTE
   • This page offers adjustments for Ethernet port settings
   • DHCP – Enable or disable Ethernet DHCP mode. 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 the IP Gateway
7. SYSTEM
   • This page provides a collection of system-level functions including On Screen Display (OSD), reset unit to Factory settings (Reset) and Color Calibration.
   • Language – sets on-screen messages to either English or Chinese.

   • OSD Time – adjusts the amount of time menus remain on screen.
   • OSD Transparency – adjusts the Transparency of menus for visibility
   • Knob Config – customize the functions of Menu Knob. The default operation of the menu knob, when menus are not on screen is as the headphone volume control. Each press after that will bring up a different function. The first, or default, function can be changed so that it is Back Light, Brightness, Contrast, Saturation, or Sharpness.
   • Color Calibration – when it is turned on, all picture modifications will be turned off and the image will be restored to its native, uncalibrated, state.
   • Comparison En – When Comparison Mode is enabled, one-half of the display will show an uncorrected image the other half will show the effect of Log, HDR, or Gamma settings (whichever ones are turned on at the time). This is a useful tool for analyzing the effects of these image modifiers.
   • Reset – sets all menu choices back to the way the unit ships from the factory.
8. EXIT
