Depending on the installation method, the projector can be divided into table type front projection, ceiling front projection, table rear projection, and ceiling rear projection. Portable projectors that are convenient for use anywhere, anytime are generally table-type front projections. This projection method is greatly affected by ambient light. However, if it is designed to be a ceiling-mounted front projection method, it is not only more cost-effective, but also has the most display effect. outstanding. Today, the desktop projector is not the same as the commercial machine. The color matching is very fashionable. The choice can be based on the decoration design, and choose the right color to match with other home appliances.
1. Installation of the hanger <br> The upper part of the hanger is a square frame with 8 through holes of 6 mm in diameter. The 8 holes are the mounting holes for connecting the hanger to the upper fixing part of the ceiling. The distance between the mounting base surface and the ceiling surface depends on whether the projector is hidden inside the ceiling. If hidden inside the top, this distance should be greater than the sum of the height of the hanger after contraction and the height of the projector itself.
2. Projector installation <br> The bottom of the hanger is a universal hanger for the projector. According to the size of the projector, adjust the lever of the universal hanger to connect the projector.
3. Electrical connection <br> Connect the power cable and control cable correctly according to the wiring diagram given. The various wires of the projector itself are installed as follows: two wire ropes are respectively sleeved with a plurality of small rings. When the hanger reaches the maximum stroke, the wires of the projector are first fixedly connected with the small ring by the plastic cable tie, and then Down to the upper "Z" form is connected to the two heel wire. When the hanger moves up and down, the various wires of the projector will move between the two wires.
4. Adjust the height of the hanger <br> There are two stroke switches on the upper part of the hanger to control the upper and lower positions of the hanger. Loosen the bolts on it and press the mark to move the travel switch left and right to adjust the position of the hanger and then tighten the small bolts.
After installing the projector, the first step in setting up a home theater is to connect the projector. Most of the projectors are fully connected, and the connection level of the TV, computer, and DVD can be easily completed, but it should be noted that Some projectors have incomplete cable connections. If you are connected to a computer, you need to have a video output port on the graphics card, or connect the graphics card to the projector through a single cable. Be sure to ask when you purchase. As for the entire sound system, it is only necessary to properly connect the projector to an audio, amplifier or other multimedia audio-visual equipment. Welcome to China Home Theater Network
The installation of the projector is relatively simple, but the realization of a home theater with excellent audio-visual effects must also pay attention to both the space and the projection environment. Since the size of the entire space directly affects the audio-visual effect of the theater, the projector must be placed at a distance of 3 to 5 meters from the wall or the curtain to achieve the best display effect. As for the hearing, in order to achieve a realistic In the situation, the room in which the projector is placed is preferably rectangular, which can play a unique role in the harmony of the modulation sound. In terms of projection effect, most of the current projectors have a brightness of more than 1200 lumens, but it is recommended to install curtains in the room to block the outdoor light. At the same time, the walls and floors of the room should not use reflective materials as much as possible. Low lamp brightness to extend the life, and secondly to avoid other details affecting the fidelity of the video effect. Also, don't let the seat close to the audio equipment or the amplifier when you watch it, which will make the sound effect very poor.
Projector adjustment:
In general, installing a projector doesn't mean you can start enjoying your favorite movie right away. In order to get better results, we have to adjust it. First, the resolution is adjusted. At present, the longest resolution of the computer is 1024×768. If the projector you choose supports 1024×768 resolution, basically no adjustment is needed, but if you use a projector that supports the highest resolution. It is 800×600, but the resolution set by the computer is 1024×768 or higher. In this case, the projector will automatically display the image with the compression function. Although we can see the image normally, the display quality of the screen is greatly reduced. Therefore, the resolution of the video source should be set according to the resolution supported by the projector to match each other for best results.
The next step is to project the image onto a wall or screen, move the projector to project the image to the correct position, and adjust the projector lens knob to focus, while the image of the projected image should fill the entire screen as much as possible. If the image appears trapezoidal or parallelogram, it can also be adjusted with the built-in trapezoidal error correction function of the projector.
Projector tips:
1. Before turning on the projector, you need to confirm that the projector cable is connected properly, and make sure the video source has been output normally. After completing the projection connection and turning on the projector, you also need to switch the output mode. Because there are three ways to output the projector, you can press and hold the Win logo button and the F5 button (when connected to the notebook, you can press the Fn button and the F8 button) to select the appropriate screen output method.
2. In the eyes of users who are not familiar with the projector, the projector is like an ordinary TV set. If you want to turn it off, most of it will be cut off directly. As everyone knows, this kind of operation is to use the "big taboo" of the projector, because the direct shutdown of the projector under long-term use will seriously affect the life of the projector bulb. Proper power-on sequence: Turn on the projector power button first, then press the Lamp button on the projector's operation panel. When the flashing green signal stops flashing, the power-on is completed. Correct shutdown sequence: first press the Lamp button, when the screen appears to be really shutting down, press the Lamp button again, then the green signal light on the projector control panel starts to flash, and wait until the projector's internal cooling fan stops completely. When the green signal stops flashing, turn off the projector and turn off the power. In addition, between each opening and closing operation, it is best to ensure that there is an interval of about 3 minutes, in order to allow the projector to fully dissipate heat. The opening and closing operations are too frequent, which may cause the projector bulb to burst or the internal electrical components of the projector to be damaged.
3. Whether the projector lens is clean or not will directly affect the clarity of the content on the projection screen. When various circles or spots appear on the screen, most of the dust on the projection lens is “causedâ€. At the same time, the projector lens is very delicate. When you are not using it, you need to cover the lens cover to avoid dust. When cleaning, you should use professional lens paper or other professional cleaning agent to remove dust from the projector lens.
