■Aspect Ratio Settings

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

As the V-R842DP-DVI monitor has a native resolution of 1024 x 768 RGB pixels, incoming images are automatically scaled to fit the screen:

•In 4:3 mode, images are scaled up or down to fill the entire 4:3 screen (1024 x 768).

•In 16:9 mode, images are scaled to fill the maximum 16:9 portion of the screen (1024 x 576), with black bars filling the remainder of the screen.

Note: The aspect ratio setting is ignored when Pixel-to-Pixel mode is enabled.

■Scanning Modes

Use this setting to switch between normal and underscan modes:

•In normal scan mode, the active portion of the video signal is displayed on the screen, with 0% overscan.

•In underscan mode, 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.

■Delay Modes

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

•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.

Note: Delay modes are only available in normal scan mode.

Connect the 12VDC input to the 2-Pin twist lock power input connector. Power can be supplied from the included power supply, or from a variety of DC sources supplying at least 3.5 Amps at 12 Volts.

IMPORTANT: If using a power source other than the included power supply, be sure that the polarity of the DC input is correct:

2Signal Input/Output

Connections:

•VGA (HD-15)

•DVI (29-Pin connector, DVI-D signals only)

Each tally light is activated via the HD-15 connector by connecting the corresponding pin to ground. A variety of external devices can be used to perform the contact closure. No additional power should be supplied to the HD-15 port.
