Connecting Multiple Displays for Video Wall Applications
To daisy chain multiple displays for a video wall application, connect a video source to the 1st display
into the chain with the supplied DVI cable (or DP cable) and RS-232 cable. Connect the DVI-OUT of
the 1st display to the DVI-IN of the 2nd display. Using the RS-232 cable provided, connect the RS-232
OUT of the 1st display to the RS-232 IN of the 2nd display. Repeat the connection for the remaining
displays. Use the OSD Menu or Display Manager software to confi gure the size of the video wall and
the position of each display.
Note:
• The maximum number of displays in a Video Wall is 36.
• The DynaScan “Display Manager” application is required to be installed on the PC in order to use
the External Control feature
• The Daisy Chain Setting (video wall function) only supports a resolution of 1920p x 1080p.

Installation
The LCD must be properly installed using a wall mount. Incorrect installation may cause injury or
damage the equipment. Product warranty does not cover the damage caused by imporoper installation.
Mounting
• Hanging the Professional LCD from the ceiling or mounting it on the wall is the responsibility of
the user. Not all ceilings or walls provide enough strength to support the LCD. The LCD may drop
and cause serious injury if it is hanging from the ceiling with insuffi cient support or is mounted on
a slanted wall. Product warranty does not cover improper installation, modifi cation, or damage
caused by natural disasters. It is recommended to have a certifi ed professional to evaluate the
installation site and perform the mounting operation.
• Do not cover the vent and/or the heat sink in order to ensure proper heat dissipation.
• Refer to the installation guide provided by the manufacturer for proper mounting.
When mounting on a wall or hanging from a ceiling
• A wall mount is not included in the accessory. Please purchase a VESA Standard wall mount to
secure the LCD.
• Verify that the mounting location can support the weight of the LCD before installation.
• Do not install the wall mount while the power is turned on as it may cause serious injury due to a
electrical shock.

Installation
4 in
Allow a minimum of 4” clearance beneath the display to allow for proper ventilation.
When hanging from a ceiling
• Ensure that the ceiling is strong enough to support the LCD and it accessories. Earthquake,
unexpected vibration and other external forces should be taken into consideration when evaluating
the ceiling strength.
• The LCD should be secured to the building’s structural frame such as a beam rather than light
steel frame or interior decoration.
• Do not use wood screws or dry wall anchors for installation.
Maintenance
• Inspect the fasteners regularly for signs of loosening or deformation. Please perform appropriate
corrective measures when a problem is identifi ed. Neglecting the problem may worsen the
situation.
• Increase the inspection frequency on areas where previous maintenance had occurred to ensure
the problems do not occur again.
