Put a sheet of cloth, paper, cardboard or other non-

tape from the top set-

screw hole

The light block tape covers the hole on the Optical

Engine top cover next to the LCD interconnect board.

In this hole is the screw that adjusts the horizontal

position.

9. Adjust the position of the

LCD

From the rear of the VideoWall, adjust the three .050”

hex socket head screws so that the LCD is centered on

the screen.

The horizontal adjustment screw is accessed through a

hole next to the LCD Interconnect board. Use the grid

lines as a reference when making adjustments.

The 2 vertical tilt-and-adjustment screws are located

through the large access holes in the LCD Fan assembly.
