3.0 CHECKING PACKAGE CONTENTS
Before attempting to use this unit, please check the packaging and make certain the
following items are contained in the shipping carton:
•1x LM-1750HD 17” Color LCD Monitor
•1x Operations Manual
•4x Rackmount Screws
•1x AC Power Adapter Mounting Bracket
•1x AC Power Adapter
Note: Please retain the original packing material should the need ever arise to return
the unit. If you find any items are missing, contact your reseller or TV One immediately.
Have the Model Number, Serial Number and Invoice available for reference when you
call.
4.0 CONNECTING THE HARDWARE
Refer to the illustrations below. The first drawing is the front view of the LM-1750HD.
This drawing will allow familiarization with the overall layout the unit.

6
The next drawing shows the Input and Output connectors plus the DC Power Input.
Connect the cables from the desired video or PC source to the appropriate input. In the
case of the SDI/HD-SDI input, you may loop the output to another device if you wish.
Connect the furnished AC to 12 VDC adapter and gently rotate the connector barrel to
lock in position. Lastly, if tally operation is desired, wire a mating DB-9 plug for the tally
connector and connect it to the monitor. Shorting pins 1 and 6 on the Tally connector
will cause the Tally LEDs at the top of the front panel to illuminate.
4.1 Power Supply Bracket and VESA Mounting Provision
As seen in the illustration below, a bracket is provided that can be affixed to the left, rear
of the monitor to hold the AC Adapter. If desired, attach the bracket and place the AC
adapter in the bracket is such a manner as to prevent physical interference with other
equipment in the rack.
Four (4) pre-drilled and threaded attach points are provided in the center to allow
mounting of the LM-1750HD directly to a wall or other structure using VESA 100mm
standard mounts available from third party vendors. Please note that the rack ears
remain in place, even when a VESA mount is used. Also, use of a VESA mount may
preclude the use of the AC adapter mounting bracket.

5.0 OPERATION OF THE LM-1750HD
After mounting the LM-1750HD in a rack and connecting the appropriate cables and the
AC adapter, press the power button, select the appropriate input and adjust the vertical
viewing angle if desired.
Input selection is made by pressing the appropriate button on the front panel. The
possible selections are HDMI, PC, YPbPr, SDI, AV1 (either Composite Video or S-
Video, but not both at the same time) and AV2 (Composite Video).
Once the input selection has been made, you may choose the image’s aspect ratio and
also adjust the audio volume of the monitor’s built in speakers.
5.0.1 Aspect Ratio Adjustment
The vertical arrows allow you to cycle through three possible aspect ratios: 4:3, 16:9
and 1:1. 4:3 is the standard analog aspect ratio used in NTSC and PAL formats for
most video signals. 16:9 is the de-facto standard for High Definition Video signals as
well as some standard definition video such as the occasional non-HDTV DVD video
signal. The 1:1 selection equals a pixel ratio of 1:1. It allows a display of signals in their
native resolution. If the signal does not fill the screen due to its resolution, it will be
displayed in actual size. Resolutions beyond the capability of the LM-1750HD will not be
visible.
5.0.2 Audio Level Adjustment
To adjust the audio level, use the two horizontal arrows. The right arrow increases the
audio level and the left arrow reduces the audio level.
5.1 Using the On Screen Display Menus
Beyond simple use of the monitor, users should acquaint themselves with the On
Screen Display (OSD) and Menu structure. Within this functionality the user can fine
tune the operation of the unit and often make improvements to the appearance of the
displayed image. Using the OSD menu is not difficult and allows you to adjust the
picture quality of the monitor.

8
5.1.1 Menu Navigation:
To utilize the menu and the OSD, press the Menu button. This makes the Menu list
appear and you will then use the four arrow buttons to navigate the list and make
adjustments. The up and down arrow buttons allow you to scroll through the list and the
left and right arrow buttons allow an adjustment or selection to be made.
The Menu List and Function are as follows:
