• In 4:3 mode, images are scaled up or down to fill the maximum 4:3 portion of the screen.
• In 16:9 mode, images are scaled to fill the entire 16:9 screen.
• In Full Screen, images are scaled to fill the entire screen.
• In Custom mode, images scaling is adjusted to your selection in the Adjust portion of the menu:

Adjust
Use any of the rotary knobs to select your desired aspect ratio. Some of the more common aspect ratio settings are shown on the Aspect Ratio selection widget. As you move along the scale, your current aspect ratio will be displayed below the widget.In the image above, 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.

• Invert
  The Clip 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 Clip data.In the image above, the Lower Threshold is set to 20 IRE and the Upper Threshold is set to 90 IRE. The Clip Invert will filter all data in between 20 IRE and 90 IRE and color it RED.

• Monochrome
  Enabling Monochrome in the Clip filter will convert all video to monochrome first, and then apply the Clip filter. This helps visually filtered data stand out from regular color video.

• Apply To Waveform
  Enabling Monochrome in the Clip filter will convert all video to monochrome first, and then apply the Clip filter. This helps visually filtered data stand out from regular color video.

• Peaking (Focus assist)
  The Peaking Filter is used to aid the camera operator in obtaining the sharpest possible picture.
  You can turn the Peaking filter ON and adjust the Threshold and Color by accessing the Adjust function. Use the BRIGHT knob to adjust the Threshold. Adjusting the Threshold to a higher value forces the Peaking algorithm to react quicker to objects that are in focus. Use COLOR knob to adjust the Color. Your choice is are Red (default), Yellow, Pink, Green and Blue.

• Clip
  The Clip function 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 filtered with a custom color.The Lower Threshold numerical value and color can be adjusted using the BRIGHT and COLOR knob, respectively.
  The Upper Threshold can be adjusted using the CONTRAST and USER knob, respectively

• Pixel-to-Pixel
  Use this setting to enable Pixel-to-Pixel mode.
  This mode bypasses the monitor’s internal scaling function and displays images in their native resolution and aspect ratio, with a one-to-one mapping of incoming image pixels to screen pixels:
  • For incoming formats smaller than the native resolution of the screen (or selected aspect ratio), the image will be displayed in the center of the screen using only the necessary LCD pixels. For example, 720p images will occupy exactly 1280×720 pixels in the center of the screen. The surrounding screen area will be black.

• DSLR Preset
  Use the DSLR Preset option to reduce the visibility of on screen indicators shown with popular DSLR cameras. The available options are :
  • NK 16:9
  • NK 3:2
  • CN 16:9
  • CN 3:2

Color Submenu

• Temperature
  Use this setting to choose one of three color temperature presets:
  • D55 (5500K)
  • D65 (6500K)
  • D93 (9300K)
  • Custom (Adjustable Color Bias and Gain)
  • Linear (No processing is applied to the panel)

• Bias & Gain
  Select this submenu to fine-tune the monitor’s color balance (R, G, B). This should only be done by someone experienced with video engineering, as this will alter the overall color shading of the screen. The purpose is to allow color matching to other types of monitors and/or displays. Note: The Color Temperature preset will automatically switch to Custom when Color Bias settings are adjusted. It is normal for color bias adjustments to be very subtle.
  When selecting the RGB Bias and Gain submenu, bias adjustment indicators will appear at the top of the screen, and gain adjustment indicators will appear at the bottom of the screen:
  This monitor has a false color filter 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 equipment. To best utilize this feature, you must understand the color chart below 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. Over exposed 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).

Filters Submenu
Use the Filters Submenu to enable various modes.

■ Check Field
Use the check field modes for monitor calibration or to analyze individual color components of an image. In Monochrome mode, all color is disabled and only a grayscale image is shown. In Blue, Green, and Red check field modes, only the selected color will be shown.
Use the following procedure when calibrating the monitor to SMPTE color bars with the following procedure:

1. Allow the monitor to warm up for at least 5-10 minutes.
2. Display SMPTE split-field color bars on the monitor using an external source.
3. Enable Monochrome mode.
4. Locate the pluge pattern (super black, black, and gray bars) at the lower-right corner of the screen. Adjust the Brightness knob until there is no visible difference between the super black and black bars, but the gray bar is still visible.
5. Adjust the Contrast knob until an even grayscale appears along the top bars.
6. Disable Monochrome mode.
7. Enable Blue Check Field mode and adjust the Color knob so that the outermost bars (white and blue) appear to match in brightness.
8. Disable Blue Check Field mode.

• False Color Use the ▲ and ▼ buttons to select each individual bias or gain control. Highlighting the BIAS or GAIN icons enables a group change of the Red, Green and Blue color components, respectively. Alternatively, you can use the BRIGHT knob to scroll through the different color components and settings.
  After selecting the color component to adjust, use the ▲ and ▼ buttons to increase or decrease the value.

• Gamma
  Use the Gamma setting to adjust the value of the gamma applied to incoming video signals. The default gamma value is 2.2. Gamma correction represents the relationship between the pixel levels from your incoming video and the luminance of your monitor. The lowest gamma level available, 1.6, will cause the image to appear brighter. The highest gamma level available, 2.4, will cause the image to appear darker. The chart below shows this on a scale.

• Color Space
  Use this setting to automatically detect (Auto) or select the color space (RGB or YCrCb) of incoming HDMI video. This should match the color space of the video output settings on your playback device.
