3D Configuration Submenu

14
■Channel A/B Input Format
Used to determine the type of signals applied to the inputs.
Normal – Select this when connected to a dual-stream HDSDI Stereoscopic source. (Separate Left and Right
on two BNC/Coax Cables) – Usually from a 3D Camera Rig, or 3D Editor.
Side-By-Side* – Used when Stereoscopic source is formatted Side-by-Side on one BNC/Coax Cable. Usually
from a 3D Processor used for transmission or distribution.
*Note* To use this feature, the same side-by-side signal must be connected to the Left and Right inputs.
(Simply connect a short BNC Coax cable from Left-Out to Right-In)
■Output Swap
This changes the Left-Right polarity of the screen when using 3D glasses. This might be necessary when
viewing the monitor at extreme high or low viewing angles. Also can be used when Left/Right images are
reversed and it’s not convenient to reach the input connections.
Video Configuration Submenu
■Monochrome Mode
Use this setting to enable monochrome mode. Only the luminance of the image will be displayed as a grayscale
picture.
■Blue-Only Mode
Use this setting to enable Blue-Only mode. This mode displays only the blue color component of the image,
switching off the red and green components. Use this mode when calibrating the monitor to SMPTE color bars
with the following procedure:
1. Allow the monitor to warm up for at least 5-10 minutes.
2. Display SMPTE split-field color bars on the monitor using an external source.
3. Enable Monochrome mode.
4. Locate the pluge pattern (super black, black, and gray bars) at the lower-right corner of the screen. Adjust the Brightness knob until
there is no visible difference between the super black and black bars, but the gray bar is still visible.
5. Adjust the Contrast knob until an even grayscale appears along the top bars.
6. Disable Monochrome mode.
7. Enable Blue-Only mode and adjust the Color knob so that the outermost bars (white and blue) appear to match in brightness.
Video Configuration Submenu

15
■Pixel-to-Pixel Mode
Use this setting to enable Pixel-to-Pixel mode.
This mode bypasses the monitor’s internal scaling function and displays images in their native resolution and
aspect ratio, with a one-to-one mapping of incoming image pixels to screen pixels:
• For incoming formats smaller than the native resolution of the window (or selected aspect ratio), the image
will be displayed in the center of the window using only the necessary LCD pixels. For example, 480i
images will only occupy exactly 640x480 pixels in a particular channel window in Quad mode, or if the
channel is selected full screen, it will occupy exactly 640x480 pixels in the center of the screen. The
surrounding screen area will be black.
■Aspect Ratio Settings
Use this menu option to switch between several aspect ratio settings.
As the 3D-241-HDSDI monitor has a native resolution of 1920x1200 RGB pixels, incoming images are
automatically scaled to fit the screen:
• In 4:3 mode, images are scaled up or down to fill the maximum 4:3 portion of the screen (1600 x 1200).
IMD text and time code are superimposed on the lower portion of the image. The audio presence indicator
and on-screen tally are displayed at the bottom of the screen, outside the image.
• In Scaled 4:3 mode, images are scaled to a smaller 4:3 portion of the screen, leaving space for IMD text,
tally, and audio presence indicator to be displayed below or around the image. Time code is superimposed
on the lower portion of the image.
• In 16:9 mode, images are scaled to fill the maximum 16:9 portion at the top of the screen (1920 x 1080). In
this mode, IMD text and on-screen tally are displayed below the image. Time code and the audio presence
indicator are superimposed on the lower portion of the image.
• In Full Screen (16:10) mode, images are scaled to fill the entire 16:10 screen (1920 x 1200). In this mode,
all OSD features are superimposed on the image. Note that when using a 16:9 input image in this
mode, the image will be vertically stretched by approximately 10%.
The diagrams on the following page show how IMD text, timecode, and the audio monitor icon are
simultaneously displayed on the screen in each aspect ratio setting. The white area represents the video image.

16
■Curtain Color
Use this setting to choose the default color displayed on the screen when no video input is present. Available
colors are blue,red,green,white, and black.
■Ctemp/Gamma
Use this setting to choose one of three color temperatures / gamma presets or to remove gamma application:
• Linear (No gamma applied)
• 55K
• 65K
• 93K
■Framelock ON-OFF
Used to designate system timing reference, Framelock – Off means system runs on internal clock reference. All
inputs are re-synced and converted to internal clock. Framelock – On mean that system timing is taken from one
of the inputs connected to the unit. This is usually A-Left. This allows monitor to use a known-stable input source
as a reference-lock to the entire system. This can improve performance when 1 or more inputs are frequently
switched and are non-synchronous. In some conditions, selecting Off will reduce the time needed for image
lock.
