Comparison OfficePro MA411B vs OfficePro MA501

The angle within which the screen installed on the mount can rotate. Measured from far left to far right. In modern models, it can reach 180°.

The angle within which the screen installed on the mount can rotate. Rotation refers to turning around a horizontal axis perpendicular to the screen; see "Adjustments" for details. And the angle is usually indicated from one extreme position to another.

According to this parameter, two categories of mounts can be distinguished. In one of them, the rotation angle is small — about 10 – 15 ° — and this feature is mainly intended to compensate for inaccuracies made during the installation of the structure: even if the mount hangs slightly unevenly, rotation allows you to set the screen straight. The second variety is models with a rotation angle of 180° and above (up to 360°); they allow user to rotate the screen from landscape to portrait and vice versa.
