Your Nixplay Signage Displays, including Small Format Signage, can use VESA and keyholes for mounting on walls.
VESA is a standard defined by the Video Electronics Standards Association for mounting flat panel monitors, TVs, and other displays to stands or wall mounts. It is implemented on most modern flat-panel monitors and TVs.
Those holes on the back of your flat panel display follow standards created by the Video Electronics Standards Association (VESA). These hole patterns correspond to measurements that all of the major TV manufacturers use in order to ensure your flat panel screen correctly attaches to a mounting bracket.
If Keyholes are provided on your Display's model you may opt for this wall mounting approach.
Keyhole mounting is used to secure or hang an object against a flat surface. The main reason for using this type of mounting system is to hide the hanging hardware for a neat and clean look. A keyhole-shaped hole is already supplied in some of the Displays.
Keyhole slots are a great way to hang the displays on a wall. The mounting screws should be perfectly level and spaced exactly the same as the slots.
You may wish to consider this table for the advantages if you are going to choose between wall or keyhole mounted.
