Brightness as an important parameter of the projector also determines its price to a large extent. Currently, the brightness of projectors on the market ranges from several hundred to tens of thousands, which brings high difficulty to the user to choose the brightness. Cinema projector projector brightness is generally 800-1500 ANSI lumens, general business conference projectors are 1500-4000 lumens, and large-scale dedicated projectors are above 5000 ANSI lumens. Now we focus on the brightness selection of home theater projectors.
First of all, we need to find out whether the projector you purchased is a dedicated video projector or a multi-purpose projector. Generally, it is a pure home projector. The brightness is generally in the range of 800-1500 lumens. If it is a multi-purpose projector, such as commercial and residential. With projectors, the brightness is higher, generally around 2000, because they are used as corporate briefings in addition to home theater. Vendors have different ratings for lumens. Commercial projectors are graded in data mode, while home theater projectors are graded at video speed. Since the lumen output of the video is different from the data, the brightness of the home projector appears to be lower than that of the commercial model. In use, commercial projectors may lose half the brightness in video mode.
How much brightness is appropriate? Mainly look at the space environment used and the size of the screen.
First, select the brightness according to the screening environment
That is, the screening environment determines the brightness: there are usually two types of home theater space, one is a professional home theater with controllable lighting, and the other is a modified living room. The space used by the projector has a certain influence on the determination of the brightness requirement. In addition, the use and time of use of the projector also have a great influence on the image brightness performance.
Living room (1000 lumens or more): The home theater converted from the living room, the time the projector is used and the content used to watch will have an impact on the brightness of the screen. Sports events and cartoons are not too affected by brightness even during the day due to their high brightness and bright colors. But like some movie blockbusters, it is suitable for watching in the dark, so the details of the image will be clearer.
Professional screening environment (800 lumens or more): Professional home theater (indoor lighting control, no ambient light) requires a lower brightness than an environment that produces ambient light from windows. In fact, when the brightness is too high, the details of the dark part of the image will be distorted.
Second, select the brightness according to the screen size
Before purchasing a projector, you must consider the screen size you need. Note that it is best to use a 16:9 ratio screen. The larger the screen you want, the higher the brightness you need.
According to the usual experience, the contrast between brightness and screen model is as follows:
80-100-inch screen requires 800 lumens of brightness. 100-120-inch screen requires 1000 lumens of brightness. Screens of 120 inches or more require 1300 lumens or more.
In summary, the choice of home projector is best to choose a professional home theater projector with a 16:9 ratio screen, the brightness should not be too high, the contrast is as high as possible, the screening environment is best to do some extinction, if you want to know which The projector is suitable for your particular screening environment, preferably consulting professional sales and technical engineers.
