Adjusting to SMPTE or split fi eld color bars.

1. Allow monitor to warm up for 5-10 minutes minimum. Adjustments will not be accurate on a cold monitor.

2. Display SMPTE color bars on monitor. Turn on Mono

3. Find the PLUGE (superblack, black, and gray bars) at the lower right of the pattern. Adjust BRIGHTNESS control until there is no
difference visible between the superblack and black bars, but a difference is visible between the black and gray bars.

4. Adjust CONTRAST control to achieve a balanced gray scale across top bars.

5.Turn off Mono then turn on BLUE GUN

6. Turn up CHROMA (color level) control until the two outermost bars (white and blue appear to match in brightness.

7. NTSC Only - Adjust COLOR PHASE (tint or hue) control until the third bar from the left (cyan) and the third bar from the right
(magenta) appear to match in brightness.

-16:9 Marker Frame Aspect Markers appear as RED lines that are used to frame the image for
an additional screen format when 16:9 display is enabled. For example 4:3 marker is often used
for HD broadcasts that are also down converted and cropped for SD transmission.
Frame markers are available for 4:3, 15:9, 14:9, 13:9, 1.85:1, 2.35:1 and 2.37:1 screen aspects.

-Safe Area Primarily used with Character Generator or CGI to identify the area of the screen
that will not be blanked by the overscan of consumer TV sets. Select between choices of 93%,
90%, 88%, or 80% of the active picture area. Please note that the screen of the V-R171P-AFHD
has been factory adjusted to display 100% of the active picture.

Display Scale Menu - Scaling is the process whereby the image is enlarged or reduced to fi t on
the screen.
As the native LCD displays of the V-R171P-AFHD are 1280 pixels wide by 768 pixels high, it is
often necessary to change the size of the image to fi ll the whole screen.
Pixel to Pixel mode bypasses the enlargement/shrink of this scaling function and displays the
native incoming format. Zoom and Underscan are disabled.

For 525-NTSC/480P based images, pixel to pixel will appear as a 640 pixels wide by 576 pixels
high (4:3 aspect) or 720 pixels wide by 480 pixels high (16:9 aspect).
For 625-PAL/576P based images, pixel to pixel will appear as a 640 pixels wide by 576 pixels
high (4:3 aspect) or 720 pixels wide by 576 pixels high (16:9 aspect).
For 720 line HD based images, pixel to pixel will appear as a 1280 pixels wide by 720 pixels
high (16:9 aspect) with displaying native resolution.
For 1080 line HD based images, pixel to pixel will appear as cropped 1280 pixels wide by 768

pixels high (15:9 aspect) starting from the center of the image
Zoom Area
will program the zoom enlargement value, 64%, 36%, 16% that will be enabled with the ZOOM button.
Underscan (Not Available for HD and PC Signals)
Displays scaled images without vertical and horizontal blanking applied. This function can only be used with Standard defi nition signals.
SDI signals will display all data input with ancillary data appearing to the right of the image.

OSD On/Off

Activates continuous On Screen Display for status and input format.
