Flat large matrix video wall mount is video wall mounting system, with an open design and custom spacers, capable of multi-monitor stacking. The stacking allows for a customized video wall mounting system with spacers (designed for specific flat-panels, not included) that streamline individual display alignment. Not all walls are perfectly flat and hence this framing system comes with top-adjustable display mounting brackets. These brackets have 3 labeled adjustment points on each arm to fine-tune alignment on the x, y and z planes, post-installation.
