Aspect Ratio Settings

Use to switch between Full Screen, 4:3 and 16:9 aspect ratios.

As the V-LCD70P-HDA monitor has a native resolution of 800 x 480 RGB pixels, incoming images are automatically scaled to fit the screen:

• In Full Screen, images are scaled to fill the entire 15x9 screen.

• In 4:3 mode, images are scaled to fill the maximum 4:3 portion of the screen (640 x 480), with black bars filling the remainder of the screen.

• In 16:9 mode, images are scaled to fill the maximum 16:9 portion of the screen (800 x 450), with black bars filling the remainder of the screen

VIDEO CONFIGURATION SUBMENU (continued)



Pixel-to-Pixel Mode

Use this setting to enable Pixel-to-Pixel mode.

This mode bypasses the monitor’s internal scaling function and displays incoming images in their native resolution and aspect ratio, with a one-to-one mapping:

• For incoming formats smaller than the native resolution of the LCD panel (800 x 480), the image will be displayed in the center of the screen using only the necessary LCD pixels. For example, NTSC images will occupy exactly 720 x 480 pixels. The surrounding pixels will be black.

• For incoming formats exceeding 800 x 480 pixels, only the center 800 x 480 of the incoming image will displayed occupying the whole screen, with the remainder of the picture cropped. For example, 1080i formats will both be cropped to 800 x 480 and displayed full-screen.

Note: Pixel-to-Pixel mode disables aspect ratio control and H/V Delay.



H/V Delay

Use this setting to enable one of three delay modes (H & V Delay, V Delay, H Delay):

• In H & V Delay mode, both horizontal sync and vertical sync are delayed, resulting in both horizontal and vertical blanking periods being shown on the screen.

• In V Delay mode, vertical sync is delayed so that the vertical blanking period is displayed on screen.

• In H Delay mode, horizontal sync is delayed so that the horizontal blanking period is displayed on the screen.



Underscan

Use this setting to enable or disable Underscan mode:

• When Underscan is OFF, the active portion of the video signal is displayed on the screen, with 0% overscan.

• When Underscan is ON, the area around the active video area is displayed on the screen, resulting in blanking intervals being shown around the perimeter of the active image. Use this mode to clearly view the edges of the active video area.



NTSC Black Level

Set the NTSC Black Level according to the type of NTSC composite video input:

• 7.5 IRE: Use this setting for standard NTSC-M signals which use a 7.5 IRE setup (black level).

• 0 IRE: Use this setting for NTSC-J signals which have no setup, or a black level of 0 IRE.

Note: This setting is disabled for PAL composite input and all component formats.

FILTER CONFIGURATION SUBMENU



False Colors

The V-LCD70P-HDA has a false color filter to aid the in setting 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).

False Color Key

FILTER CONFIGURATION SUBMENU (continued)



Peaking Filter (Focus assist)

The Peaking Filter is used to aid the camera operator in obtaining the sharpest possible picture. When activated, all color will be removed from the display and a black-and-white image will remain. The internal processor will display RED color on the screen where sharp edges appear. When the camera operator adjusts (racks) the focus control (on the camera lens), different parts of the image will have RED colored edges. This indicates that that portion of the image is sharp – or in focus. Final focus is achieved by racking the camera lens focus control back and forth until the desired portion of the image has RED colored edges. Please note that this feature is most effective when the subject is properly exposed and contains enough contrast to be processed.



Mosquito Filter

Use this setting to filter out “Mosquito Noise” – an artifact that appears as specs around edges of objects. This artifact is the result of video that has been compressed at some point. Video sources from DVD-Players, PDA’s, Digital Cable Boxes, Camcorders, etc. often have this artifact.
