The following features may not be available on all Marshall camera-top monitors. Please, check the monitor's features on the individual pages.

DSLR RATIO ADJUSTMENTMarshall's new DSLR RATIO ADJUSTMENT feature allows users to scale video that does not completely fill the monitor's screen when connected via HDMI in "Record" mode on certain Canon DSLRs. This new feature allows the user to scale their DSLR video output, fill the screen, and eliminate black pillar bars with a variety of options to choose from. The user has the option of choosing between NORMAL, 3:2, 16:9, and FULL SCREEN. The DSLR RATIO ADJUSTMENT feature can be programmed to one of the front panel's four-button presets for quick and easy access.

The False Color filter is used to aid in the setting of camera exposure. As the camera Iris is adjusted, elements of the image will change color based on the luminance or brightness values. This enables proper exposure to be achieved without the use of costly, complicated external test equipment.

To best utilize this feature, you must understand the color chart and have a basic understanding of camera exposure. Normally, when shooting subjects like people, it is common practice to set exposure of faces to the equivalent of approximately 56 IRE. The False Color filter will show this area as the color PINK on the monitor. Therefore, as you increase exposure (open the IRIS), your subject will change color as indicated on the chart: PINK, then GREY, then a few shades of YELLOW. Overexposed subjects (above 101 IRE) on the monitor will be shown as RED. In addition, underexposed subjects will show as DEEP-BLUE to DARK-BLUE, with clipped-blacks indicated with a FUCHSIA-like color. Lastly, the color GREEN is used to indicate elements of the image that are approximately 45 IRE. This represents a "neutral" or "mid-level" exposure commonly used for objects (not people).

UNDEREXPOSED Underexposed objects show as DEEP-BLUE to DARK-BLUE
PROPERLY EXPOSED Properly exposed objects will display elements of GREEN and PINK

The original version of the peaking filter removed the color from the image leaving a black and white picture with Red highlights. This new version not only keeps the original color but adds a choice of four colors, Red, Green, Yellow and Pink to choose from for the highlights as well as adjustable sensitivity for even finer control of focus. The Peaking Filter is used to aid the camera operator in obtaining the sharpest possible picture. When activated, the internal processor will display a colored highlight on the screen where sharp edges appear. When the camera operator adjusts (or "racks") the focus control (on the camera lens), different parts of the image will have these colored highlights. This indicates that this portion of the image is sharp or in focus. Final focus is achieved by racking the camera lens focus control back and forth until the desired portion of the image has the colored highlights.

Please note that this feature is most effective when the subject is properly exposed and contains enough contrast to be processed.

The Zebra function (Clip Guide) is used to visually filter data on the screen that is under a Lower Threshold or over an Upper Threshold. Data on either side of the filters can be displayed with a custom color.

Lower Threshold Lower Threshold has been set to 20 IRE

In the image above on the Right, the Lower Threshold has been set to 20 IRE (Red). This means that any part of the image UNDER 20 IRE will be "colored" in RED. Also, the Upper Threshold has been set to 90 IRE (Yellow). This means that any part of the image OVER 90 IRE will be "colored" in YELLOW.

Zebra function The Zebra function can also be inverted to filter the area between the Upper and Lower Threshold. The color selected for the Lower Threshold acts as the color for all inverted Zebra data. In the image on the Left, the Lower Threshold is set to 20 IRE and the Upper Threshold is set to 90 IRE. The Zebra Invert will filter all data in between 20 IRE and 90 IRE and display it in RED.
