FAQ

Frequently Asked Questions

What should I do if the image appears distorted on a 3×2 video wall?

To avoid distortion on a 3×2 video wall, enter the number of rows and columns as 3×3 during configuration.

How do I control individual displays?

Press the red Picture ID ON button to control a single display.
To control all displays simultaneously, press the Picture ID OFF button.

What is the default input source for the displays?

The default input source is HDMI, which is correct for the display(s) connected to the player. Other displays should have their input changed to DisplayPort.

Introduction

Tiling an image on an LCD video wall shows the image at a larger scale across the displays as opposed to displaying the same image repeated on each individual display.
In any video wall configuration, individual LCD displays are assigned a Set ID number (called a Screen ID number on the Riser Drawing) and a Tile ID number.
For example, in a 3×3 video wall, the individual displays are numbered as shown in Figure 1.

As the LCD displays are mounted to the wall, one display is attached to the player (not necessarily display #1) and the other displays are daisy chained together:

Cable connected from the player to the display – HDMI
Cables connected between the subsequent displays – DisplayPort and RS-232C

Note: Cabling for a 4×4 video wall is slightly different with a repeated player output. In this case, two HDMI cables connect the player to display #5 and display #13. Refer to the Riser Drawing DWG-5309976 for more information.

Video Wall Configuration

The following steps include information from LG® manuals, refer to the specific manual for more details.

Set the Input for each LG® Display

Follow the basic setup wizard prompts to configure each LG® display.
Ensure that each display has the correct input source using the INPUT button on the remote control. The default of HDMI is correct only for the display(s) receiving the signal from the player; all other displays should have the input changed to DisplayPort.
