WN-5220-S VideoWall User’s Guide

During this alignment process, the

screen is removed from the Adapter

Plate. Then the Adapter Plate is

adjusted to make its corners square

and to 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.

Basic Steps for Alignment

This is a summary of the steps necessary to build a video wall thin mullion

displays and align their screens. Each step is expanded, and detailed

instructions follow this summary.

1. Remove the screens from all the display units.

2. Build the video wall.

3. Start with the display unit in the center of the bottom row and align its

Adapter Plate. (This step can be done

before

the wall is built, if

necessary.)

4. Working along the bottom row in both directions, align each of the

adapter plates, using the Alignment Tool.

5. Align the adapter plates on the rest of the rows, working upward.

6. Hang the screens on the bottom row and adjust them in or out so the

front surfaces (the screen faces) are flat with each other.

7. Hang the screens on the upper rows, and make them flat.

8. Put retaining screws in the top row and cover any holes and seams with

black tape to prevent light leaks.
