Audio Level Meter Display

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

blue only

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.

H/V Delay

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

Locks the knob or key control.

Luma(Y') Zone Check

Luma(Y') Zone CheckLuma(Y') Zone CheckLuma(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.



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.

Range Error

Range ErrorRange Error

Anahlyzes the input signal’s Luma(Y’) and chroma information(C’) and if the input signal exceeds the designated minimum value and maximum value, the pixel shall blink. This function is to help the user to easily find out any unwanted levels of signals and for a better exposure setting.

Time Code Display

Time Code Display

Displays the Timecode information on the screen.

User Aspect

User AspectUser AspectUser Aspect

Adjusts the Width /Height display ratio.

Various Scan Modes

Various Scan ModesVarious Scan ModesVarious 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.



Magnifies the input signal from 0% to 90%.

1:1 Pixel Mapping Modes for SD/HD

Displays the original image resolution without scaling to match a certain resolution or an aspect ratio.

3G-SDI Level A/B

Supports 3G-SDI Level A/B input.



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

PBP(Picture by Picture)

PBP(Picture by Picture)PBP(Picture by Picture)PBP(Picture by Picture)

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