Upward tilt angle
The maximum upwards tilt angle from the vertical of the installed screen. The larger the tilt angle, the wider the adjustment possibilities, however, in fact, an angle of more than 5° is rarely required.
Downward tilt angle
The maximum downward tilt angle from the vertical for the installed screen. As with the upward tilt angle, the larger this angle, the wider the adjustment possibilities; however, downward tilt is usually required more frequently (the TV may be installed under the ceiling), and its angle can be as high as 15-20°.
Rotation angle
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.
