**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 “detail” to the image. HD images should require very little added sharpness. Default value is 0.

• RGB Range – choose the RGB range of the HDMI input between Full or Limited. 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 PC, set top box, or other device to configure itself for best video quality. This choice only applies to HDMI inputs.

• Color Space – select the display gamut from among Native, SMPTE-C, Rec709, EBU. Rec709 is the most common setting.

• Camera Log – use this to choose one of the camera Log modes among Def log, User log.

• Def. Log – Default (preset) Log modes. When viewing material from a camera that has a Log gam-ma 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, 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 offering 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. Gamma range is 1.8 to 2.8
• 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 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.
• 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 Bright-ness 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.

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 Dis-play 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.
  • Marker Mat – darken the background just behind the markers.
  • Thickness – sets the width of the markers.

DISPLAY

• 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. The most common is 16:9.
  • Pix to pix – displays the incoming video with a 1:1 pixel match. This provides the clearest resolu-tion 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. In either case, the image is shown in it’s “true” resolution.
  • Zoom – expands the picture digitally. It is normal for picture quality to become less sharp 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 trouble shooting.
• Image Freeze – holds the current picture on screen.

WAVE

• Full Mode – The following analysis functions are full-sized and fill the entire display. In this mode, 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, RGB presentations.
  • Y – This is the most common setting and represents a traditional waveform monitor. It graphically represents the full Luma range of dark to light across a scene from left to right. Color information is not represented.
  • YCbCr – This graphically displays Luminance plus the matrixed color components. It is useful for equipment adjustment and confirming proper operation.
  • RGB – This graphically displays the three primary color components. It is useful for making ad-justments and analyzing color content.
  • Vector – This graphically representation of the colors in a picture in “color wheel” format. Lumi-nance is not represented. The vector display is best used with color charts and test signals.
  • Audio – shows an on-screen bar graph of audio channels (typically Left and Right) from either an HDMI or SDI digital source.
  • 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. 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 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 com-monly found in broadcast camera viewfinders which provides a quick way to check for over-exposure.
  • Exposure Level – to adjust the level of peaking. The exposure level can be set to [50]-[100]. Histogram – This mimics a feature commonly found in DSLR cameras
    Y – a graphical representation of the tonal distribution within a picture.
    RGB – a graphic representation of the three primary color components of video picture. Useful for making equipment adjustments.
    COLOR – a graphical representation of the mixed RGB distribution within a picture.

AUDIO

• Volume – controls the Headphone volume.
  Volume can also be controlled by turning the menu knob when menus are not on screen. 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 CH – With HDMI input, channel pairs may be selected from 1 – 8.
  With SDI 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.

REMOTE

• 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

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.

• Color Bar – places color bars on screen to check the monitor operation.

• 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 uncor-rected 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 items back to the way the unit ships from the factory.
