First of all, you need to know the type of projector you want to buy, whether it is a zoom or fixed focus type projector, can it support functions such as picture displacement or keystone correction; the second is the projection distance, the projection ratio of each projector They are all different. The projection distances of different brands of projectors are different. You need to pay attention to it. Third, you need to determine the installation type. There are several installation types, such as front projection, ceiling projection, and wall mounting. the same. Reasonable wiring and confirm the decoration plan of the final environment.
How to install a home projector?
1. First confirm the size of the room, and what size screen can be made. The length of the room and the width and height of the projection wall correspond to the relative projection size of the projector. Example: The projection distance of the Liying projector is 3.75 meters, and it can be projected. 120-inch screen (2.58*1.62 meters in length and width).
2. Determine the type of installation, front projection, hanging projection, and wall mounting.
Relatively speaking, the front projection is simple. You only need to cast the screen at the corresponding projection distance to watch the movie. The operation is very simple, but there is a flaw. You need to adjust the screen every time you move the projector.
Hanging projection is to fix the projector on the ceiling to project. This installation method solves the user’s multiple manual adjustments. It only needs to be fixed once/adjusted once and the ceiling is placed on it for a long time. It is a long-term fixed decoration method.
Compared with the ceiling projection, the projector is installed on the wall. The wall mount can be retracted back and forth, which is convenient to control the projection distance of the projector. The distance can be adjusted according to the actual situation. The only conditions that need to be met are the projection needs to be close to the wall to support The wall-mounted installation method.
3. Decorate the wiring. Before fixing the location of the projector, you must first reserve the wire. After the projector is installed, you can wire it. High-end home theaters may have great requirements for environmental decoration, so you need to lay hidden wires.
4. The actual method of determining the projection distance is to power on the projector, and the projected picture will be filled with the screen. After confirming the actual installation distance, fix the projection bracket. This is the traditional method of fixing the position of the projector, and it is more reliable. It is inevitable that there will be some errors in the projection distance parameters. At this time, it is necessary to use the human eye to actually adjust it.
After fixing the projector, if the upper and lower widths of the picture are inconsistent, you can use the projector’s built-in function “keystone correction” to adjust the upper and lower widths of the picture to be consistent. Most projectors support up and down keystone correction, and some projections support left and right keystone correction. Before confirming whether the projector supports the “left and right keystone correction” function, be sure to pay attention to the projector lens and the center of the screen when fixing the projection bracket. Yes, this can avoid the phenomenon that one side of the projected image is low and the other is high. If there are other uneven images, you can make slight adjustments by adjusting the projection hanger.
