How to Make a 3x4 Video Wall

We completed a 3x4 screen lcd video wall project in Vietnam recently. The project is progressing smoothly. After the completion, the customer sent us Some project pictures, hereby I would like to share with you the entire video wall installation guide.
First of all, when the customer receives the 4 screen video wall goods, we will ask the customer to open the box for inspection, turn on all the screens, and check if there are any issues with the screens.

After checking, start preparing for installation. Normally, the screen is good because we pack it well and there is thick foam inside the honeycomb box.
