Mechanical Setup, Ultra-Thin Mullion or Blackscreen

CAUTION The displays with Ultra-Thin Mullion screens are not serviceable from the front. Service should be performed through the rear access cover. Instructions for BlackScreen are the same as for Ultra-Thin Mullion screen.

You will need these tools:

•a large, flat blade screwdriver

•an SAT-500 Screen Alignment Tool (two of these tools makes installing a video wall even easier.)

•black cloth tape

•a tape measure (inches or centimeters)

•1/2” open-end wrench, a 1/2” deep-well socket, or an adjustable wrench

•5/64” Allen hex wrench

The thin mullion display screens consist of two basic parts. There is the screen itself and the frame it is held in, an assembly which is about 3” (7 cm)

thick. The screen attaches to the second part, an adapter plate which is about 2” (5 cm) thick. The adapter plate is mounted on the front of the display unit.

During the alignment process, you remove the screen from the adapter plate, then adjust the adapter plate to make its corners square and align correctly with its neighbors. Then the screen is re-installed and adjusted in or out.

Installing a video wall with Ultra-Thin Mullion Screens is a little more complex than installing the wall with standard mullion screens. Mechanical alignment is more critical, and the larger the video wall, the more precisely each unit must be aligned to produce a good looking image. The outcome of this alignment process is partly dependent on how flat the floor is, but it is mostly dependent on how tightly the displays are fitted to each other.
