With the popularity of high-definition projectors, it is believed that more and more people will change their mindset to accept this new thing.
If you use the cost per square inch of screen as the standard for purchase, you will definitely choose a home projector. However, the real reason why the projector is not recognized by most consumers is that most people have no chance to see the real effect of the home projector, and the projector is rejected from the home with some early impressions. Ok, let's put aside the prejudice and get to know the home projector again.
Prejudice 1: I don't like too much picture, it will be dizzy.
Let's first take a look at the dimensions needed to achieve cinematic effects.
1. When the ratio of the screen size to the field of view is 30 degrees, it is the best angle of view and the best sense of presence.
2. When the distance between the eyes and the picture is 3 times the height of the screen, it is the best line of sight and it will not dizzy.
According to these two points, even if the traditional Chinese living room is not very large, the 3-meter line of sight can also watch the 80-inch 16:9 picture. The editor personally experienced it, and the large picture can express the big people like the real person, and it is more realistic. There is no feeling of dizziness in a reasonable line of sight.
Prejudice 2: The picture quality is not good, and LCD TV is no match.
Many people who come back from the mall experience will find that the projector screen is dim, rough and unobtrusive. The reason is that the bright shopping mall environment makes the projection screen greatly discounted, and the liquid crystal is direct light, which is not easily affected by the environment. Anyone who has used a projector knows that enjoying a home theater must eliminate all interference factors and devote all of his heart to the world of movies. LCD TVs have no problem in bright and noisy environments, and the projector has a high ball for the environment. You need to pull up the curtains and turn off the lights to make the picture perform better.
1. The picture is smooth, there is no tailing phenomenon of the LCD, it is more suitable for watching large movies.
2. The brightness is lower than that of the LCD, which is more suitable for watching movies for a long time, and it is not easy to make the eyes fatigue.
3. The technical parameters of the two are difficult to distinguish, as long as the environment is properly controlled, they all have good performance.
Prejudice 3: huge curtains and projectors affect the overall image of the home
If you consider the projector installation before the renovation, these problems will disappear automatically. Today's framed curtains are even more versatile than flat-panel TVs. A variety of video lines can be hidden by embedding, and both the curtain and the projector can be hidden in the ceiling and released only when in use.
Prejudice 4: The lamp life is too short
Generally, the lamp life of the projector is 2000-3000 hours, even if it is 4 hours a day, it can be used for 2 years. After all, home projectors and teaching projectors are different, most of them will not open every day. Plus reasonable use, there is no problem for two or three years.
