PROS:

Articulating TV wall mounts allow greater flexibility when it comes to changing the position of the screen. They are especially useful as they allow a screen to be installed in the corner. This is a big advantage over the flat and tilt models which require a large flat wall area. They will usually have a smaller mounting bracket which can be attached to the wall in various places. So, if you need a TV wall mount in the corner of your room, this is the type of mount you should be looking at.

CONS:

Articulating TV Mounts put a lot of stress on the wall that is why you must secure them on wall studs. Moreover, articulating TV wall mounts are much harder to install, and they have a lot more adjustments so it is best if installed by professional Installers. Articulating mounts also require longer cables because they can swivel up to 180 degrees.
