The cloud bracket is an essential accessory for projector installation and placement, which is used to adjust the pitching, left-right and horizontal angle of the projector to realize accurate screen alignment. The pitch angle determines the upper and lower projection range of the projector. Choosing a bracket with a suitable pitch angle can adapt to different placement heights, projection distances and scene needs, avoiding the trouble of unable to adjust the picture position and incomplete screen presentation.

For desktop placement and low-height household use scenarios, a pitch angle of ±15° is sufficient for daily use. Most families place projectors on coffee tables, TV cabinets and low platforms. The projection height is basically consistent with the center of the projection screen. A small range of pitch adjustment can correct the slight offset of the picture up and down, adapt to different desktop heights, and meet the needs of daily movie watching, drama chasing and casual projection. This angle range is the most basic and practical configuration for household portable projector brackets.

For ceiling installation, high platform placement and large-screen projection scenarios, a bracket with a pitch angle of ±30° is the most versatile choice. Ceiling-mounted projectors need to adjust the downward pitch angle to align with the wall or screen below. When the projection distance is long and the screen size is large, a large pitch angle can effectively adjust the picture center position, avoid the problem of upper and lower blank edges of the screen, and match the keystone correction function of the projector to realize full-screen accurate projection. This angle is suitable for most home theater, office and conference room installation scenarios.

For special scenarios such as floor high placement, ultra-long distance projection and ceiling fitness projection, a pitch angle of ±45° is required. For example, when projecting fitness videos on the ceiling, the projector needs a large upward pitch angle; when placing the projector on a high shelf for ultra-long distance projection, a large downward adjustment angle is needed. Too small a pitch angle will lead to limited projection range and unable to fill the screen. In general, ±15° is enough for basic use, ±30° is the optimal universal angle, and ±45° meets all special projection needs.
