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. Waveform, Audio and Clip Guide Displays The new V-LCD71MD incorporates both a Waveform display and Stereo Audio bars. These may be displayed separately or together in any one of the four corners of the monitor. The Stereo Audio is de-embedded from either the HDMI input (8 channels) or from the optional 3GSDI input (16 channels). Any pair of the available channels may be selected for both the display and the Headphone Output.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. 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. 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.
