Whether the home projector is good or not, in fact, it mainly depends on the following key points:
- The brightness of the projector is suitable for the environment of use.
- Standard resolution, screen display effect.
- Projection lens material, projection size playback experience.
Next, I will share with you the knowledge of purchasing home projectors based on these three points.
- Brightness
Brightness has always been the data we are most concerned about. Many people think that the higher the brightness, the better, but it is not. When purchasing, we need to choose the appropriate light source brightness according to our own usage scenarios. If you watch the projector as a TV in the bedroom at night, then basically an entry-level home projector with 2000-3000 yuan is enough, and the brightness is good at 500ANS-1000ANSI; if you want to use the projector in a bright living room, it is recommended Choose a projector with a bulb light source or laser light source above 2000 ANSI lumens.
There are generally four types of projector light sources: LED, high-pressure mercury bulb, laser, and xenon.
Projectors with LED light sources whose brightness is within 100 ANSI lumens are suitable for use at night, and those with 2000 ANSI lumens can also be used in the daytime without strong light, and LED light sources have the advantage of long life. Its life span is basically above 2W hours.
The high-pressure mercury bulb has a high brightness, which is basically above 3000 ANSI lumens, and can be used even in the daytime. However, this kind of light bulb generates a lot of heat, and its life span is only 2000-4000 hours. It costs about 500 yuan to replace the light bulb once, and some may need to be replaced in less than a year.
Daily household lumens above 1000 ANSI lumens can basically satisfy our use.
- Display resolution
Generally, most entry-level products have 720P standard resolution, but there are also many models that can reach 1080P resolution. We recommend to purchase 1080P resolution for daily use, which will be clearer.
- Projector lens material
At present, the projector lenses on the market are generally divided into two types, one is a resin lens, and the other is an all-glass lens. The inevitable problem of using a resin lens is that there will be defocusing during use. , In the case of out of focus, then the use of all-glass lenses can avoid this problem.
Although we don’t pay much attention to the projection ratio data, if we want to project a larger picture as much as possible in a smaller room, we still choose a projector with a smaller projection ratio as much as possible. For general household use, the projection ratio of 1.2:1 is very suitable. It only takes about 2.6 meters to project a 100-inch super large screen, and it can also realize the fun of casting a super large screen at home.
In terms of user experience, the most mainstream function currently on the market is automatic keystone correction. It can be said to be an essential function. Especially friends who rent a house now, considering the size of the space. Then the position of the projector will basically move at any time. You might put it on the side of the bed, or on the cabinet next to the sofa. Then the unadjusted picture is definitely not in line with our viewing effect, so at this time the keystone correction function can be very effective.
The above are the key points that we need to consider when choosing a home projector. We can focus on understanding these conveniences in the selection. As long as these aspects meet your needs, then this projector will definitely be suitable for you. Daily use.
