• Check FieldUsed to calibrate or analyze the accuracy of the screen color when Check Field is switched on. Selectable:Off/Red/Green/Blue/Mono. Default is Off.• FreezeTurn on to capture and display a frame of the current signal at any time. Default is Off.• PeakingUsed to assist in tracking the focus of the subject. Default is Off.• Peaking ColorAvailable colors: red/green/blue/white/black. Default is red.• Peaking LevelUse this setting to adjust the level of focus sensitivity from [0]-[100]. If there are plenty of details of the image with high contrast, it will display lots of focus assist lines that may cause visual interference. So, decrease the value of peaking level to reduce the focus lines to see clearly. Conversely, if the image has fewer details with low contrast, it should increase the value of the peaking level to see the focus lines clearly.

• False ColorThis 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. Selectable from: Off/Spectrum/ARRI/RED/Default. Default is Off.

• False Color TableTurn on or off False Color reference tables.• ExposureThe exposure feature helps the user achieve optimum exposure by displaying diagonal lines over areas ofthe image that exceeds the set exposure level.• Exposure LevelThe Exposure Level can be set from 50 to 100IRE. Default is 100IRE.

• HistogramThe horizontal axis of the histogram represents the luminance, from left to right indicating low to high luminance. The vertical axis of the histogram indicates the number of pixels, from bottom to top indicating the number of pixels from less to more. The higher the histogram bumps in a certain luminance range, the more pixels there are in that luminance range. For example, if the histogram’s bumps are mainly on the left side, this means that the overall brightness of the image is low; if it is on the right side, the overall brightness is high; if it is in the middle, the brightness is comfortable.

2.3.7 Audio

•  VolumeAdjusts the volume of built-in speaker and headphone, selectable range: 0-100. Default is 50.• MuteDisable any sound output when turning it off.• Level MeterTo achieve optimum audio quality, ensure the audio levels do not reach 0. This is the maximum level, meaning that any audio that exceeds this level will be clipped, resulting in distortion. Ideally, peak audio levels should fall in the upper end of the green zone. If the peaks enter into the yellow or red zones, the audio is in danger of clipping.• Audio SourceSelectable range: SDI1/SDI2/HDMI1/HDMI2/TYPE-C, Full Screen or Vertical mode default to the current audio source, Multiview mode defaults to SDI1
