How to choose home projector? What should I pay attention to when using home projector?
First, how to choose home projector?
1, brightness
Brightness is one of the important indicators for choosing a projector, and it also has a great influence on the price. For traditional light sources, the gap of several hundred lumens may increase the price of projectors by several thousand yuan. At present, the classification of intelligent projection is also relatively clear, and you can choose according to your own usage scenarios when purchasing.
2. Projection light source
At present, the main light sources are high-pressure mercury lamp, high-brightness LED light source, laser light source and high-pressure mercury lamp, which have relatively poor service life. High-brightness LED light source has moderate service life and brightness, which is generally suitable for household use. Laser light source has long service life and high brightness, but its price is much higher. Generally used in laser tv, the price is around 10,000 yuan or even higher. Household generally choose high brightness LED light source, and the price is relatively moderate.
3. Protrusion ratio
Projection ratio is a parameter that is easily ignored when selecting projection. Due to the limited indoor space, the projection ratio will affect the maximum screen size we can project. Many products that claim to be able to project 100 inch or even higher can't really project such a large display area due to the limitation of our family space, so the smaller the projection ratio, the better, so that we can project a larger picture in a limited space.
Second, what should I pay attention to when using home projector?
1. If you want to use the projector for a long time, you need good maintenance. After the projector stops using, don't turn off the power immediately, turn it off and wait until the machine cools down. The damage caused by power failure when the machine is cold is one of the most common reasons for maintaining the projector.
2, can't use the lens cover to block the picture. Sometimes, during the use of home projector, we need to turn off the projector screen temporarily, but it will be very troublesome to turn it on after turning it off. At this time, if the lens is temporarily blocked by something, the front temperature of the fuselage will rise sharply, affecting the components. The correct way is to find the close button of the projector and temporarily close the screen display.
3. The projector is easily affected by ambient light in use, so it is necessary to choose a good projection environment to block outdoor light, and do not use reflective materials on walls and floors.
When choosing a home projector, it depends on the brightness, projection light source and projection ratio of the projector. These are only some of the purchase factors, and other factors such as resolution should also be considered. Combine these to choose a projector with appropriate price and satisfactory use effect. When using the projector at ordinary times, be careful not to turn off the power immediately after stopping using it, don't use the lens cover to block the picture when you don't look at it temporarily, and don't take shading measures where you use it.
