Does anyone have any experience using Dell 2407 or 2405 with any of the Ergotron LCD arms, in particular 45-174-300 or 45-172-300? I wonder if 2407 is too thick (which moves center of gravity beyond recommended 1" from the mounting plate) or too heavy to be used with one of these arms. Other than a potential problem holding the position stably with a heavier monitor these arms seem to be a very ergonomic and space efficient solution (as well as not as costly as many others).
