In the late aughts I worked a summer at a company that was designing an articulating (flat screen) TV mount. I went with the engineers to one of the Intertek testing sessions. We wanted it to be rated for a 60" TV, but I was given the impression that the weight formulas they used for testing were based on CRT screens. The salesperson who came with us was giddy seeing the thing loaded up with 1000lb of steel plates and not giving way, but the actuators could not lift and our advertised rating was not more than 200lb.
