Illuminates Red when system power is present. Illuminates Green when monitor is ON.

System reset will also occur with Off/On cycle. Active Outputs require power to be applied.

All input signals appear as output signal. Analog output signals are buffered and amplified.

2. Source Selection Buttons

HDSDI - Digital Input for Standard Definition (SDI-270Mbs) or High Definition (HDSDI-1.43Gbs) Video - Composite NTSC or PAL. Composite video must comply to SMPTE-RS170A.

Images without color burst (Subcarrier) component may not display. S-Video- Y/C (Luminance + Chrominance) NTSC or PAL

YPrPb - Analog Component color difference signals for Standard Definition (YCrCb) or High Definition (YPrPb) VGA/DVI - Toggles between Analog PC or DVI-I connectors.

DVI - Digital or Analog Computer or Video Signals. Includes HDCP and can be used with HDMI originated signals via an adapter cable

3.Under Scan (Not Available for HD and PC Signals)

Displays scaled images without vertical and horizontal blanking applied. This function can only be used with Standard definition signals. SDI signals will display all data input with ancillary data appearing to the right of the image.

4. Aspect Ratio

Displays scaled images in three screen aspect formats. 4:3 used mainly for Standard definition

16:9 used mainly for HDTV images.15:9 or Fill Mode is indicated by illuminating both LEDs. This mode will fill the entire display screen regardless of the original screen aspect.

5. Pixel to Pixel Function

As the native LCD display of the V-R231P-AFHD is 1920 pixels wide by 1200 pixels high, it may be necessary to change the size of the image to fill the screen in the desired aspect. Pixel to Pixel mode bypasses the enlargement/shrink of this scaling function and displays the native incoming format.

For 525-NTSC/480P based images, pixel to pixel will appear as a 480h x 640w (4:3 aspect) or 480hx720w (16:9 aspect). For 625-PAL/576P based images, pixel to pixel will appear as a 576h x 640w (4:3 aspect) or 576w x 720h (16:9 aspect). For 1080 line HD based images, pixel to pixel will appear as 1080h x 1920w (16:9 aspect)

For 720 line HD based images, pixel to pixel will appear as a 720h x 1280w (16:9 aspect)

6. Color Temperature

The V-R231P-AFHD has four color temperature settings that adjust the color balance of the screen for varying ambient conditions. D-55 (5500K) - Simulates indoor incandescent light conditions.

D-65 (6500K) - Standard setting recommended by SMPTE and EBU. Simulates normal daylight conditions. D-75 (7500K) - Simulates bright daylight conditions.

User

When USER color temperature is selected, the color balance RGB Gain and Offset adjustments will be enabled. Use UP/DOWN/LEFT/RIGHT (Safe, Mark, Frame, Overlay) to access the desired adjustment parameter.

Left Line= Increase of Gain

Right Line= Increase of Bias

Center Line = D65 (Default)

Center Line = D65 (Default)

Right Line = Decrease of Gain

Left Line = Decrease of Bias

7. OSD

 

Use SELECT to enable the On Screen Display for input and function status.

 

Note that when turned off, a timeout of 8 seconds will pass before the display goes away.

SDI: 525i/60hz 4x3

 

8. BACKLIGHT Brightness

Holding OSD then tapping SAFE will toggle through 3 selections of backlight intensity.

High = 100% Backlight Brightness (approx. 250 cd/m2)

Med = 75% Backlight Brightness (approx. 188 cd/m2)

Low = 60% Backlight Brightness (approx. 140 cd/m2)
