1. PICTURE

This page provides controls for typical picture adjustments.

www.marshall-usa.com 7

V-702W Menu Settings

Brightness – used to establish the correct black level in the picture. Default value is 50.

Contrast – establishes the range of dark to light areas in the picture. Default value is 50.

Saturation – sets the amount of color information in the picture. Default value is 50.

Sharpness – adds “detail” to the image. HD images should require very little added sharpness.

Default value is 0.

RGB Range – choose the RGB range of the HDMI input between Full or Limited. Only applies to

HDMI inputs. When viewing HD video based on television standards such as REC 709, Limited is the

correct choice. When working with computer graphics Full may provide

a wider range of color.

HDMI EDID – select the HDMI EDID from between 4K and 2K. This item enables PC, set top box, or

other device to conﬁgure itself for best video quality. This choice only applies to HDMI inputs.

Color Space – select the display gamut from among Native, SMPTE-C, Rec709, EBU. Rec709 is

the most common setting.

Camera Log – use this to choose one of the camera Log modes among Def log, User log.

Def. Log – Default (preset) Log modes. When viewing material from a camera that has a Log gam-

ma curve applied, the pictures will not appear normal unless the matching Log mode is selected.

User Log – use this item to install and apply a “User LUT” (Look Up Table) instead of one of the

Default Logs

To install a User Log “LUT”:

- Check that the User LUT name ends with “.cube”. (This is common).

- Two types are accepted: 17×17×17 or 33×33×33, Data order is BGR, Table order is BGR.

1. Rename the LUT ﬁle as User1.cube up to User6.cube. (6 ﬁles may be stored in the monitor)

2. Copy the user LUT onto a formatted USB drive.

3. Insert the USB drive into the USB port on the rear panel of the monitor. The User LUT will be

imported into the monitor automatically. If the User LUT does not load automatically, a message

will appear with “no user data” or offering a choice to manually load the User LUT. If “no user

data” appears please check that the ﬁle meets all the requirements noted above.

Gamma – Gamma correction applies a non-linear “curve” to the displayed range between dark and light.

Historically, 2.4 is chosen because it is the inverse of a standard camera Gamma of 0.45 producing a

roughly “linear” match. Today, different camera Gamma values are often applied for creative purposes so

a different monitor Gamma may be chosen for viewing. It is best practice that, once set, Gamma is not

changed during a production shoot or an editing or color correction session. Gamma OFF would be used

only during testing, calibration or when using an external video processor. Gamma range is 1.8 to 2.8

HDR – HDR “High Dynamic Range” is used to properly view video that has been enhanced through

one of the common HDR processes. Three SMPTE ST 2084 standard settings are available. These

are calibrated to 300, 1000 and 10,000 NIT displays. (The only 10,000 NIT displays are projectors). A

fourth setting is available, HLG, which is commonly used for broadcast. When HDR is activated, the

display can reproduce greater dynamic range of luminosity. The best results will be obtained when

various on-screen markers

Menu Settings

the monitor setting matches the HDR emphasis that was applied to the video material. Using HDR

mode with non-HDR material typically looks very unnatural.

Back Light – adjusts the brightness of the LCD backlight. This is different from the “Brightness”

control. Backlight is adjusted to compensate for room lighting without upsetting Contrast and Bright-

ness adjustments. It is generally best practice to set the Back Light level before changing other

picture settings.

Color Temp – this setting provides four different presets for white balance approximating different

common color “temperatures”. The most common is 6500K. USER allows for custom calibration by

adjusting Gains and Offsets. as desired:

R/G/B Gain – adjust the Red, Green, or Blue Gain of the current Color Temperature from 0 to 255.

Default value: 128.

R/G/B Offset – adjust the Red, Green, or Blue Offset of the current Color Temperature from 0 to

511. Default value: 256.

1. PICTURE (continued)

Center Marker – places a “+” mark in the exact center of the display. (Useful for checking camera or

graphics positioning.)

Aspect Marker – places borders on screen representing various typical video and

cinema aspect ratios. This does not change the displayed aspect ratio. That setting is in the Dis-

play menu.

Safety Marker – places a border around the edge of the screen to be used as a guide during

video production.

Marker Color – the Center, Aspect and Screen marker colors can be changed.

Marker Mat – darken the background just behind the markers.

Thickness – sets the width of the markers.

3. DISPLAY

Scan – Adjust the scan mode among Aspect, Pixel to Pixel, Zoom.

Aspect – allows changing the aspect ratio (shape) of the picture to match the incoming video.

Settings are available for various video and cinema styles. The most common is 16:9.

Pix to pix – displays the incoming video with a 1:1 pixel match. This provides the clearest resolu-

tion but usually changes the size of the image. This turns off up/down “scaling”. For example: a

video input that has fewer pixels than the LCD display will appear to shrink while a video input that

has more pixels will appear to expand. In either case, the image is shown in it’s “true” resolution.

Zoom – expands the picture digitally. It is normal for picture quality to become less sharp as the

picture is expanded.

Overscan – enlarge the image slightly to reduce image edge distortion.

H/V delay – shifts the picture vertically and horizontally to allow viewing the vertical and horizontal

“blanking areas” which contain the HANC and VANC ancillary data.

Check Field – displays the picture in monochrome (black & white) or in individual primary colors.

Useful for color analysis and trouble shooting.

Image Freeze – holds the current picture on screen.

4. WAVE

Menu Settings

Full Mode – The following analysis functions are full-sized and ﬁll the entire display. In this mode,

Video is not displayed

Waveform – Selecting Waveform instead of Full Mode places a compact version of the Waveform

Monitor function as an overlay at the bottom of the display. Overlays are limited to Y, YCbCr, RGB

presentations.

Y – This is the most common setting and represents a traditional waveform monitor. It graphically

represents the full Luma range of dark to light across a scene from left to right. Color information

is not represented.

YCbCr – This graphically displays Luminance plus the matrixed color components. It is useful for

equipment adjustment and conﬁrming proper operation.

RGB – This graphically displays the three primary color components. It is useful for making ad-

justments and analyzing color content.

Vector – This graphically representation of the colors in a picture in “color wheel” format. Lumi-

nance is not represented. The vector display is best used with color charts and test signals.

Audio – shows an on-screen bar graph of audio channels (typically Left and Right) from either an

HDMI or SDI digital source.

Transparency – change the visibility of the chart on the screen. Adjust as desired for best visibility.

Peaking – adds a colored edge to picture details making it easy to identify which areas are in

sharpest focus.

Peaking Color – Select one of the peaking colors: Red, Green Blue, White, Black.

Peaking Level – adjust the amount of peaking color. The range is 1 - 100.

The Wave page offers adjustments for the

on-screen Waveform monitor, Vector scope

displays, and video assist functions like focus

peaking, exposure “zebras”, false color lumi-

nance level check.
