3G-SDI Level A/B

Supports 3G-SDI Level A/B input.

Audio Level Meter Display

Displays the level of the embedded sound signal together with the video signal input through the terminal such as SDI or HDMI.

Blue Only / Mono

Red and Green channels are not used and only Blue or Monochrome channel is used to display the screen. This function is used to adjust the color tones (tones and saturation) of the screen using the SMPTE Color Bar. For example, after displaying the Blue channel, adjust the Color (or Saturation) and Tint (or Hue) so that the original Magenta and Cyan are of the same brightness, and the original Gray and Blue are of the same brightness.

Closed caption

Closed caption.

H/V Delay

Allows you to check the Blanking area and synchronize signals by displaying the horizontal and vertical intervals in the center of the screen.

Key Lock

Key Lock is a password-protection function of the OSD menu so that non-authorized users cannot change the setting of the monitor.

Luma(Y') Zone Check

Displays the Luma(Y’) level of the input image in colors. Each pixel’s Y’ analyzed and changed to a certain color or zebra pattern according to the Index on the right side of the screen.

Marker

Displays various kinds of aspect ratios on the screen. Wide range of markers and security areas are available with line color and curtain transparency selection. A User Marker is available if any of standard markers fits your requirements.

PBP(Picture by Picture)

Support displaying multiple inputs on the screen at the same time.

Range Error

Analyzes the input signal’s Luma (Y’) and chroma (C’) information. If the input signal exceeds the designated minimum and maximum values, the pixel will blink. This function allows for the user to easily identify any issues with exposure.

Time Code Display

Displays the Timecode information on the screen.

UMD

Displays user customized 8 characters or source ID or Tally signal of Ancillary (ANC) data on the screen.

User Aspect

Adjusts the Width /Height display ratio.

Various Scan Modes

Controls the size of the image. Overscan: Extra area around the four edges of the image that may not be seen reliably by the viewer. Underscan: Constrains the size of the image so the monitor shows everything the camera is seeing. 1:1 pixel: Displays the original image resolution without scaling to match a certain resolution or an aspect ratio.

Waveform/Vector Scope

Waveform Y: Displays the Luma(Y’), Cb, Cr component of the input signal into waveform.
Vector Scope: Displays the color components ‘B-Y’ and ‘R-Y’of the input signals onto the X-Y axis.

Zoom

Magnifies the input signal from 0% to 90%.
