Premier Mounts offers a basic Brand + Model mount finder on every page of their site. They listed my Proscan brand and model, although there were far fewer other Proscan models listed compared to the other sites.

Based on my input, a range of different mount types and kits were returned, and all were capable of matching my display’s weight and mounting pattern.

On top of the basic mount search based on brand and model, Premier also offers a Mount Configurator that allows the user to input responses to a series of questions including things like weight, mounting surface, weight, and mount pattern allowing you to not just get the basics right, but also assure the mount you select will play nice with your wall and other environmental concerns.

This extra level of detail ensures the installer or consumer gets just the right mount for the job.
