How To Configure TILE Pro Video Wall

Requirements

PC with Windows 10 or later, and Serial Port.
RS232 to RJ45 adapter - supplied with TILE unit.
DisplayPort (DP) Cable for each TILE.

If your PC does not have a serial port, you will need a USB to RS232 Serial Adaptor:

Example: Using Two 2×2 Daisy-Chained Groups + GPU Mosaic

When using DisplayPort daisy-chain mode, each group of TILE units is detected by the Operating System as one single display.

This allows you to bypass GPU output limitations to build larger video walls efficiently.

In the example below, we will configure a 4×2 video wall (8 TILE units) using:

Two independent 2×2 daisy-chained groups, A & B
Internal videowall processing per group
GPU Mosaic to merge both groups

Step 1 – Create Two 2×2 Daisy-Chained Groups

DisplayPort Cables

You will create:

Group A → 2×2 TILE units
Group B → 2×2 TILE units

Each group has 4 TILE units daisy-chained via DisplayPort cables, using 2 DP ports on the PC GPU (Source A and B), with both Groups A and B chained as follows:

DP cable from PC to to TILE 1 DP IN
DP cable from TILE 1 DP OUT to TILE 2 DP IN
DP cable from TILE 2 DP OUT to TILE 3 DP IN
DP cable from TILE 3 DP OUT to TILE 4 DP IN

Ensure each group Is detected in the OS display settings as one 3840×2160 (4K) display.

Step 2 - RS232 Daisy-Chain

RJ45 Cables

The entire videowall needs to be daisy-chained via RS232, and this can be done in one continuous chain, no splitting into groups required, example below:

RJ45 cable from PC to TILE 5 RS232 IN
RJ45 cable from TILE 5 RS232 OUT to TILE 6 RS232 IN
RJ45 cable from TILE 6 RS232 OUT to TILE 7 RS232 IN
RJ45 cable from TILE 7 RS232 OUT to TILE 8 RS232 IN
RJ45 cable from TILE 8 RS232 OUT to TILE 4 RS232 IN
RJ45 cable from TILE 4 RS232 OUT to TILE 3 RS232 IN
RJ45 cable from TILE 3 RS232 OUT to TILE 2 RS232 IN
RJ45 cable from TILE 2 RS232 OUT to TILE 1 RS232 IN

Step 3 - Configure the Video Wall in the Software

Open Device Manager and Expand "Ports (COM & LPT)" to see which is the Serial Comm Port:
Launch LcdWall.exe
To change the language, select the 2nd menu item, and English is the lower option on the list:
Select the corresponding COM port from the dropdown menu, or click Refresh to auto select:
Enlarge the window, or enter full screen mode to reveal more controls, and click on Open COM

You will notice the text change in the bottom left corner:
Under the Combination Set tab, configure the matrix as 2 rows × 4 columns, then click on Set to apply:
Change Input Source to DP

Select all units by clicking on the first unit, and dragging across all the rest of the units
Right click the selection, hover over Input Source, and select DP:

Perform ID mapping

Click on the Screen Addr button:
In the dialog that opens, click on Display MacKey:
Each TILE Pro will display a unique Mac Key, example:
Starting from the first unit, in the upper row, on the left, manually enter the Mac Key seen on that Tile Pro in the Mac Key field, then enter number 1 in the Panel Unit ID field, and click on Change:
Repeat this for the remaining units, setting the second TILE Pro unit Panel Unit ID to 2, the third to 3, and so on.

Merge each group:

Select the 4 units from the first group (1, 2, 5, and 6) by clicking on one and dragging across the other 3:
Click on Merge:
Repeat the steps for the 2nd group, select units 3, 4, 7, and 8, and click on Merge:

This is within the 4K daisy-chain limit.

Step 4 – GPU Configuration

Once both groups are merged via the LcdWall software, each group outputs: 1920 × 1080. Now it is necessary to set the resolution of each group to 3840x2160 on the GPU settings, example: NVidia Control Panel - Change Resolution:
