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.
Video Configuration Submenu

13
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.
■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 QV171X-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 in
Full Screen). 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
Full Screen). 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 Full Screen).
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.

■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 Preference
Used to designate the Primary Channel as a reference for synchronizing image scaling when in any Quad
Mode. The Primary Channel will always be Ch. 1 in the default Quad Layout. In Quad Layouts 2 and 3, the
biggest window is the Primary Channel. In Quad Layout 4, the Primary Channel is the window on the left side.
Framelock allows the 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. Under
some conditions, selecting Off will reduce the time needed for image lock.

IMD Configuration Submenu
The QV171X-HDSDI features an In-Monitor Display (IMD) with the ability to display on-screen text and tally in
three colors. IMD text, color, and alignment can be assigned to each screen locally using menu options (see
below). Alternately, IMD text and tally can be remotely controlled via the RS-422/485 serial interface using
several industry-standard protocols, including TSL v4.0 and Image Video. Multiple QV171X-HDSDI monitors can
be looped together and each addressed individually via the protocol. All menu features of the QV171X-HDSDI
can also be controlled via the Marshall Network Controller box using MEI protocol. (Contact Marshall Electronics
for additional information).
Use the IMD Configuration submenu to configure various IMD parameters as described below.
■IMD ID #
The IMD ID # identifies each screen to the controlling device. When using the TSL protocol, the ID # of each
screen should be manually set in conjunction with the controlling device. When using the Image Video protocol,
the ID # may be set automatically by the controlling device, after each IMD is initially identified by IMD Name
(see “IMD Name[S/N]” below). Available ID #s are 000-254.
■IMD Group #
Each screen can be assigned an IMD Group # when using the Marshall protocol. Available Group #s are 01-
254.
■IMD Protocol
Use the IMD Protocol menu option to choose the protocol with which the QV171X-HDSDI receives remote
commands. Currently, four protocols are available. Contact Marshall Electronics for the latest protocol
compatibility.
Image Video
Use the Image Video protocol setting when controlling the IMD from an Image Video tally controller (e.g.
TSI-1000) or other controlling device which utilizes the Image Video protocol. The IMD #, IMD Name(S/N),
and Baud Rate parameters must be set for each screen in conjunction with the controlling device.
