Chapter 2 Installation

The following uses a 46-inch joint screen with 2×2 scale as an example to describe how to install
wall-mount LCD displays.

2.1 Mount Brackets



Install the brackets from the bottom to the top, from the middle to the sides.



Use the level to measure and ensure that the positioning ruler and brackets are flat or
vertical.

Step 1 Take out a bracket and secure it onto the wall with expansion bolts.
