Installation
Depending on the installation mode, the projector can be divided into the table type is cast as the vote, suspended ceiling, desk projection, ceiling-mounted projection. Convenience of anytime, anywhere using a portable projector is generally positive vote of the table, this kind of projection methods affected by ambient light effects larger but if decoration is designed for ceiling is voted, not only in price more advantages, but also the most excellent display effect. And now the desktop just vote is not a projector early commercial machines, old look very fashionable colours, the choice is based on the decoration design, select the appropriate color matching with other home appliances.
After you have installed the projector, set up home theater's first step is to connect the projector, most complete line of projectors and television sets, computers, connection to a standard DVD can easily complete Newbie, but it is important to note that not all some projector cables, and computer connection you need video with video output, or through a single connector will connect the video and projector, purchase must ask. As for the entire sound system, the formation of time as long as the projector and sound system, amplifier or other multimedia audio-visual equipment are properly connected.
Projector installation is relatively simple, but a visual effect which the implementation of home theater, you also have to pay attention to space and the projection environment. Due to the size of the entire space directly impacts the cinema effect, place the projector at a certain distance from the wall or screen to have 3 m to 5 m distance in order to achieve the best results show; as regards the aural aspect, in order to be able to achieve a realistic situation, place the projector in the room it is rectangular, so that the modem sound harmony can play a unique role. In the drop shadow effect, the majority of the projector brightness is 1200 lumens, butit is recommended that you install the curtains in the room in order to block the outdoor light, at the same time, the room walls and floors can also try not to use reflective material, in this way you can reduce the lamp brightness to prolong service life, and also avoid other details impact video effects of fidelity. In addition, the watch time to let the seat close to the sound device or the microphone, which will enable sound effects become very poor.
Adjustment
In General, installed projector does not mean that you can immediately begin to enjoy their choice of films, in order to be able to get better results, we also must be made to adjust the settings. First issue resolution adjustment, the longest currently computer with resolution of 1024 × 768, if you select the projector supports 1024 × 768 resolution, Basic does not need adjustment, but if you use the projector supports a maximum resolution of 800 × 600, but the computer settings of 1024 × 768 or more, in this case, the projector will automatically display images with compression, although we do not normally see the image, but the screen display quality has greatly diminished. Therefore, according to the projector supports resolution to set the resolution of the video source, so as to achieve mutual match to get the best results.
Then the image is projected onto a wall or a screen, a mobile projector to make the image projected to the correct location, also adjust the projector lens to focus knob on the line, while the projected image of the image to fill the entire screen. If the image is a trapezoid or parallelogram, so you can use the projector built-in trapezoid correction.
Use the skills
1. open the projector power supply before connecting the projector cable properly acknowledged, at the same time to ensure that the video source has been normal output. Complete projection connection and turn on the projector, you also need to switch good output. Because the projector output there are three ways that you can hold down Win logo key and F5 (connected with a laptop, you can press the Fn key and F8), to choose the appropriate screen output.
2. familiar with projector user's eyes, the projector is just like a regular TV, open will open; when you want to close, most of them are directly cut off the power. As everyone knows, this operation is using the projector's "taboo", because the projector in the prolonged use of direct shutdown will seriously affect the projector bulb life.　The correct boot sequence: first projector power button, and then pressing the projector Lamp on the operator panel button, wait for the blinking green light stops flashing, the power-on. Correct shutdown sequence: first press the Lamp button, when the screen is really want to shut down when you are prompted, and then press the Lamp button on the projector Control Panel then the green signal lamp starts blinking, wait until the projector internal cooling fans full stop, green light stops flashing, then turn off the projector, disconnect the power supply. In addition, each time you open, shut down, the best guarantee for a 3 minute intervals, in order to allow sufficient heat dissipation of the projector. Open, shut down too frequently easily lead to the projector bulb exploding or projector internal electrical components were damaged.
3. the projector lens is clean or not, will have a direct impact on the content of the projection screen clarity, experiencing all kinds of circles on the screen or spots, most of the projection lens dust "provoked". At the same time, the projector lens is very delicate, not sometimes need to cover the lens cap to avoid sticky dirt, cleaning professional lens should be used when paper or other specialty cleaners to clean the dust on the lens of the projector.
Troubleshooting
Why projector output image instability, there are fringe fluctuations?
This situation is essentially due to the projector power signal and the signal source and power signals not altogether, as long as the projector and the signal source device power cord plugs into the same power strip.
Why projection screen of the Fuzzy Tail occurs even shaking phenomenon?
Some of the user's computer and the projector is not in a room, a greater distance between, then extend the signal cable will cause the input signal attenuation of projector, projection screen, fuzzy tail caused even shake, so do not blindly projector signal line extension, normal conditions, the projectionInstrument signal cable length should be controlled at 15 m, this projection effect can only be guaranteed if the projector and computer are within 15 meters above the sea level, it is best to install the projector signal input signal amplifier.
Why projector use for some time after the original so bright?
Today General projector with a built-in way of penetrating the projection lamp metal lamp life 1000 hours, halogen bulb 100 hours to 200 hours. Metal lamp life is long but its brightness and with linearly decline, time use to 120 hours after the original brightness is only around 70%, while the halogen bulb life is short but its use during the brightness.
Projector's built-in speaker sound so small?
Because the projector design's main function is to throw the perfect screen, loudspeaker big will take away a lot of the machinery space, the volume will not be very large. But the projector on the market, has sound output terminals, can be used with other audio equipment to improve the sound.
