Pursuit is the driving force of everyone’s life, and the pursuit of life is the prospect of the future. Nowadays, it has gradually become a consensus of people to use projectors to replace traditional televisions to transform the way of entertainment in family living rooms. However, whether it is in a certain treasure or Dong, there are dazzling brands and models, and there are jagged parameters, all of which are promoted by merchants. They are all grotesque and colorful. Among them, there are many famous brands and models that are exciting. But, which one to choose, whether to buy the brand or the price?
Not much nonsense, teach you directly how to choose a projector.
Judging whether the projector is good or not, pay attention to the following three points:
1. The brightness of the light source is related to the use environment.
2. The display chip is related to the picture quality.
3. The projection lens is related to the projection size.
1. Choose a lumen suitable for home use
The primary factor of a projector is the level of lumens. Although tens of lumens is not practical, as a household, it is not that the higher the lumens, the better. Because the indoor volume of a family is limited, there are certain rules for the contrast of refraction brightness and chromatic aberration that the human eye bears. Long-term use of home projectors with excessive light and chromatic aberration will greatly reduce the sensitivity of the human eye, so overly compelling brightness is not an advantage. In general, whether it is a bedroom or a living room, the opening distance is basically 3-4 meters, and the wall projection size is about 100-200 inches. Based on this data, the lumen of 1000-1500 is more appropriate. Curtains are drawn during the day and small lights are turned on at night. The light is soft, the color difference is soft, and the warm feeling is the main theme of the home theater. The lumen intensity of the bulb should be commensurate with the actual volume and distance of the room.
Second, choose the bulb with a long life
Many people are often confused by the high lumen and professionalism promoted by the merchants when they buy the machine, but they ignore the life of the bulb. The lamp life of some home projectors is only a few thousand hours, and the price of replacing a lamp is about several hundred to one thousand yuan, and it is more troublesome to purchase and replace a lamp of a truly matching model. The lamp life is more than 20,000 hours.
3. Choose a home projector with rich and practical interfaces
The main purpose of a home projector is to watch TV, watch movies, play games, connect to a computer, etc.; therefore, the input terminal must have at least HDMI, AV, VGA; the unit should preferably have a built-in speaker and the output must have an audio terminal to connect to a power amplifier and speakers . At the same time, it supports remote control operation.
The essential mission of a projector is to deliver video. The key to a home projector is the word “home”. A projector developed according to the home environment and user experience is in line with the “home” 2 Word home cast
4. Projection ratio-space size
The first point of this is based on the consideration of the home environment. If you don’t want to buy the projector back, but find that the living room is not far away from the dilemma, please read the following carefully. If your living room area is more than 20 square meters, you can consider buying a projector; if it is not enough, it is not recommended. The best viewing distance is about 3-4 meters.
Five, the price
The price of projectors has a large gap, generally ranging from a few hundred yuan to 50,000 yuan, or even higher. The price of foreign brand products is generally higher than that of domestic products. The reason is not elaborated. I can only tell everyone that the current price-performance ratio of domestic products is trustworthy. The price range of general household projectors is 2000-5000 yuan.
Brightness is one of the most important indicators for purchasing a projector. Now the price of projectors is getting lower and lower, and the brightness is getting higher and higher. But in fact, too high brightness will damage eyesight, the best lumen parameter range is 800-1500ANSI.
I have never used a projector, and I don’t understand that the projector will make noise when it is used. Machine noise index is very important, but it is often overlooked. Generally speaking, products with noise below 40dB can be purchased with confidence.
Eight, the choice of curtain
If the walls in your home are not white, or if you want a better viewing effect, curtains are definitely a good choice. Projection screens are generally divided into ordinary white screens and glass bead screens.
Ordinary white screen: Advantages: low price, wide viewing angle, soft visual effect; Disadvantages: small gain to light, suitable for home use with weak background light.
Glass bead screen: Advantages: the advantages of wide viewing angle and high gain. Disadvantages: the price is high, it is not suitable to repeatedly roll up, otherwise the glass beads will fall off easily, which will affect the use effect.
