Datasheet
Multi-level Screensaver Function
Gamma mode: Optimises the gamma curve
Cooling fan mode: Fan operates continuously rather than
automatically activating when internal temperature reaches
the pre-designated limit
Brightness mode: Adjustment of display brightness
Motion mode: Images can be slightly shifted in four directions
according to user-specied time intervals
Programmable Scheduling Function
Up to seven dierent scheduled intervals can be programmed accord-
ing to time, day of week and input port. Additionally, content from
dierent souces can be scheduled for specic displays within the same
installation. Increased panel service life and energy savings are also
possible through a well-planned schedule in which displays are turned
o when not required.
Tiling Capability with Frame Compensation
Combine up to 25 panels (5 wide x 5 high) to create a single large
image (i.e video wall) or other high-impact signage. A frame compen-
sation function is incorpo-
rated to adjust for the
width of panel bezels so
that images are displayed
with the utmost accuracy.
Connect up to a maximum of 25* panels (5 x 5)
* LDT322V: a maximum of 16 panels (4 x 4)

Long Cable Compensation
Long sections of RGB signal cable may cause a loss in image quality.
To maintain maximum quality, the LDT461V2 is equipped with a long
cable compensation feature that can be turned on during installation
and adjusted for various cable lengths.
Applicable only for analog RGB
(D-sub/BNC)
Compensation level depends on
the quality of signal source
and cable

Remote Management & Diagnostics via Bi-lateral
RS-232C Communications
Use this feature to create an independent interface on a personal
computer for remote control and adjustment of displays. Models 42”
and larger can be daisy-chained to save on cabling costs as illustrated
below. Daisy-chained displays can be simultaneously controlled or
adjusted. Using a unique ID number, each display (up to 26 in a
daisy-chain) can also be controlled independently.

For the MDT Series and LDT461V2, daisy-chain capability also enables all
daisy-chained displays to be controlled simultaneously using an IR remote
controller from a single master display location, saving time onsite.
In addition, critical indicators of display status such as input signal,
cooling fan and internal temperature can be veried remotely (cooling
fan starts automatically when the internal temperature rises beyond a
certain limit). Remote asset
management is also
available to verify model
and serial number.
PiP, PoP and Side-by-side
Picture-in-Picture and Picture-out-of-Picture modes are provided,
enabling content from a video input source to be displayed in window
format while displaying the main image from the computer input
source or vice versa.
The MDT Series, LDT422V and LDT461V2 are equipped with a side-by-
side mode, an ideal feature for broadcasting and video-conferencing
applications.

Wide-ranging Colour Temperature Adjustment
Colour temperature can be adjusted
across a wide range, from 2,600-10,000K.
This is an important function for signage
displays used in broadcasting, retail, food
and other industries where image repro-
duction in true colours and tones is vital.
*For LDT322V, only colour temperatures of 5,000, 6,500 or 9,300K can be selected.
Side Border Colour Select
When the 4:3 screen is being displayed, the side border colour can be
selected from black, grey and white.
Power-on Delay
For installations employing numerous displays, the power-on delay
function allows each display to be set to power-up between 1-50
seconds after power is supplied. This
allows the displays to power-up sequen-
tially, avoiding inrush current problems
and reducing overall electrical load
requirements when using the same
power supply.
Auto Adjust & Auto Set-up
Automatically adjusts the screen position, phase and clock when the
input signal timing is changed. In addition, Auto Set-up quickly adjusts
more items such as screen size and white and black levels with a single
touch via the IR remote control.
Power-save Function for PC and Video Signals
The display can be set to automatically go into power management
mode when either the PC signal (RGB sync) or video input signal is lost.
This saves both power and the need to individually turn o each display
when not in use, such as
during the time a location is
closed.
IR Remote Lock
The remote-control receiver can be turned o to prevent unauthor-
ised personnel from changing display settings or selected inputs.

Cutting-edge technologies and features for expanding
digital signage applications
To reduce image persistence and maximise panel service life in
demanding signage applications, all models are equipped with a
four-level screensaver function. Each level can be set to meet specic
application requirements.
