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.  
2.  
3.  
4.  
Allow the monitor to warm up for at least 5-10 minutes.  
Display SMPTE split-field color bars on the monitor using an external source.  
Enable Monochrome mode.  
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.  
6.  
7.  
Adjust the Contrast knob until an even grayscale appears along the top bars.  
Disable Monochrome mode.  
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 screen (or selected aspect ratio), the image will be  
displayed in the center of the screen using only the necessary LCD pixels. For example, 720p images will occupy  
exactly 1280x720 pixels in the center of the screen. The surrounding screen area will be black.

On-Screen Menu (continued)  
VIDEO CONFIGURATION SUBMENU (continued)  
Aspect Ratio Settings  
Use this menu option to switch between several aspect ratio settings.  
As the QV171-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.

Framelock Preference  
Used to designate one of the inputs as a reference for synchronizing image scaling when in any Quad Mode. 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  
freerun will reduce the time needed for image lock.

IMD CONFIGURATION SUBMENU  
Overview  
The QV171-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 QV171-HDSDI monitors can be looped together and  
each addressed individually via the protocol. All menu features of the QV171-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 Configuration Submenu  
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.

On-Screen Menu (continued)  
IMD CONFIGURATION SUBMENU (continued)  
IMD Protocol  
Use the IMD Protocol menu option to choose the protocol with which the QV171-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.  
TSL v4.0  
Use the TSL v4.0 protocol setting when controlling the IMD from a TSL tally controller, or other controlling device  
which utilizes the TSL v4.0 protocol. The IMD # must be set for each screen in conjunction with the controlling  
device.  
MEI  
Use the MEI protocol setting when controlling the QV171-HDSDI using the Marshall Network Controller box. This  
protocol allows remote control of all features on the QV171-HDSDI, including marker setup, video configuration,  
system configuration, and image adjustments (brightness, contrast, etc.). The IMD #, IMD Group #, and Baud  
Rate parameters must be set in conjunction with the Network Controller Box.  
MEI-Image Video  
This protocol setting accepts Image Video commands via MEI protocol, for use when an Image Video controller is  
connected to the Marshall Network Controller box.  
Tally Source  
The QV171-HDSDI OSD tally can be controlled in a variety of different ways. Use the Tally Source setting to choose  
how tally is controlled:  
Standard  
Use the Standard setting to control tally via contact closure on the HD-15 tally interface.  
Image Video HW  
Use the Image Video HW setting to control Image Video tally states via contact closure on the HD-15 tally  
interface. Contact closure of the Red pin corresponds to Image Video Tally 1, and the Green pin maps to Image  
Video Tally 2. Contact closure (ground) corresponds to a LOW state, and open circuit corresponds to a HIGH  
state. This mode requires the IMD Tally Mode parameter to be set. Consult Image Video documentation for  
further information.  
Image Video 422  
Use the Image Video 422 setting to control Image Video tally states via the Image Video serial protocol. OSD tally  
will be disabled in this mode, as Image Video tally states are manifested in the text color and other parameters.  
This mode requires the IMD Tally Mode parameter to be set. Consult Image Video documentation for further  
information.  
Standard + IV422  
Use the Image Video 422 setting to control Image Video tally states via the Image Video serial protocol, while  
controlling OSD tally using contact closure on the HD-15 tally interface. This mode requires the IMD Tally Mode  
parameter to be set. Consult Image Video documentation for further information.

IMD CONFIGURATION SUBMENU (continued)  
TSL/MEI 422  
Use the TSL/MEI 422 setting to control OSD tally via the TSL or Marshall serial protocols.  
IMD Baud Rate  
Use this setting to choose the baud rate. The baud rate must be set in conjunction with the controlling device. Available  
baud rates are 300, 600, 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200. The TSL v4.0 protocol is fixed at  
38400 bauds.  
IMD Name (S/N)  
Use this setting to assign a name to each screen when using the Image Video or Marshall-IV protocols. The IMD name  
is equivalent to the Image Video serial number and is used by the Image Video controlling device to identify  
each screen. The default IMD Name(S/N) is “M00000.” It is recommended to maintain this naming scheme in order to  
avoid serial number conflicts with other Image Video devices on the same serial bus. Each name can be up to 16  
ASCII characters.  
Press RotoMenuknob to edit the IMD Name. Rotate the RotoMenuknob to move the cursor. Press the  
RotoMenuknob with the cursor on the character to be changed, then rotate the knob to scroll through the character  
set . Press the RotoMenuknob to choose a character.  
IMD Tally Mode  
Use this setting when using Image Video tally control. Choose one of the following settings, in conjunction with the  
Image Video controlling device. T1, T2, T1T2, T2T1, T1-, T2-, T1T2-, T2T1-. Consult Image Video documentation for  
further information.

IMD FIXED SUBMENU  
IMD Fixed Color  
Use this setting to choose the color of the IMD Fixed String text (see below). Available colors are red, green, and  
yellow. This setting does not affect text color when using IMD text via the Image Video or TSL v4.0 protocols (text  
color is set via the protocols).  
IMD Fixed Align  
Use this setting to choose the horizontal alignment of the IMD text. IMD text can be justified on the left, center or right  
of the screen. This setting is overridden when using IMD text via the Image Video protocol (alignment is set via Image  
Video protocol).  
IMD Fixed String  
Use this setting to display static IMD text on the screen. This setting is used to enter IMD text locally, when a serial  
protocol is not used for remote control. The IMD Fixed String is saved after power cycle. The IMD Fixed String will be  
overridden by serial protocol commands.  
Press RotoMenuknob to edit the IMD Fixed String. Rotate the RotoMenuknob to move the cursor. Press the  
RotoMenuknob with the cursor on the character to be changed, then rotate the knob to scroll through the character  
set . Press the RotoMenuknob to choose a character.

Maintenance  
Screen Cleaning  
Periodically clean the screen surface using ammonia-free cleaning wipes (Marshall Part No. V-HWP-K). A clean micro-  
fiber cloth can also be used using only non-abrasive and ammonia-free cleaning agents. Do not use paper towels.  
Paper towel fibers are coarse and may scratch the surface of the polycarbonate faceplate or leave streaks on the  
surface. Antistatic and fingerprint resistant cleaning agents are recommended. Do not apply excessive pressure to the  
screen to avoid damaging the LCD.  
Faceplate Dusting  
Dust the unit with a soft, damp cloth or chamois. Dry or abrasive cloths may cause electrostatic charge on the surface,  
attracting dust particles. Neutralize static electricity effects by using the recommended cleaning and polishing practice.
