Glossary
Max. size
The maximum size of the TV screen that can be installed on the stand/mount. Like the minimum size (see above), it is in some way a conditional indicator — TVs with a larger size can also fit for the mount, and then the main determining parameter will be the maximum weight (see below).
Max. weight
The maximum weight of the TV that can be installed on the mount/stand; more specifically, it is the maximum weight that the mount/stand can support for an indefinitely long time without any negative consequences. Unlike the screen size described above, this parameter is accurate and should not be exceeded: perhaps the stand/mount will not break immediately under excess weight, but this can happen at any time, and such a breakdown is not covered by the warranty.
It is worth considering that for classic stands with several shelves (see "Type"), the maximum wheight is usually indicated for the entire structure as a whole and is the sum of the loads for each individual shelf. Thus, the maximum weight of the TV is not limited by the total maximum wheight, but by the maximum wheight for one shelf. This does not apply to stands with mounts; they usually list the maximum wheight on the mount, in which case it corresponds to the maximum weight of the TV.
The screen size is directly related to the maximum wheight (after all, a large TV weighs more). Typically, for screens up to 24", structures with a maximum wheight of about 5-6 kg are usually quite enough, for a 32" device, about 12 kg may be needed, large 55" screens reach a maximum weight of about 25-30 kg, and in the case of plasma panels, these figures increase by 1.5-2 times However, anyway, before choosing, you should clarify the weight of the specific TV model for which the stand/mount is selected.

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.

USB hub
A set of additional USB ports provided in the design of the stand or mount. Brackets with a USB hub allow you to covertly lay wires, they are also used to connect flash drives and various peripherals. In some cases, the hub has an autonomous power source, so you can power all kinds of USB gadgets from it. Typically, a USB hub includes two or four USB 3.2 gen1 ports.
