Chief not only carries nearly any type of mount you could expect, but it has an extremely thorough mount compatibility tool for both flat-panel displays and projectors.

Present on every page throughout the site is a drop-down mount finder allowing you to select a manufacturer and specific model number. Proscan was present in the list, as was the specific model of my display.

Six full pages of recommendations were presented, ranging from standard wall mounts, powered mounts, ceiling mounts, and rolling floor carriages. I spot-checked a handful from each mount category and all were within the weight and mounting pattern requirements.

While higher up the price range, Chief MFG offers a robust mount compatibility tool, even for less prevalent brands.
