The repeated epidemics have made it difficult for many people to work and relax at home, and it has become more difficult to go to the cinema to watch a movie. Some fans in the background said that it is better to buy a projector to watch movies at home, and children can also use online classes.
Indeed, many home decorations now consider whether to install a projector, set leisure and entertainment learning as a whole, practical and atmospheric.

The projector ≠ home theater
Many people think that installing a projector will have the effect of a home theater. Here Fei Mojun wants to correct it: the projector ≠ home theater.
However, it cannot be denied that a complete projector system is indeed a replacement for home theaters.
Therefore, if economic conditions permit, it is recommended to plan a home theater; if you just want to see a movie once in a while, a projector or projection system is enough.
Look, the home theater of the female star's home is not only big enough, but also designed with a starry sky on the top, so romantic to say.
Having money can really do whatever it wants, envying ing

What does a projection system contain?
A good-use projection system consists of 3 parts: video, audio, and engineering
Video: That is, a TV or projection screen.
Audio: Speaker system, amplifier.
Engineering: acoustics, aesthetics, optical processing, cable embedding, etc.
As we all know, just a set of speakers can have a very different effect.
So, if you want to install a projection system, you still need money! money! money!
However, today we are mainly talking about the projector, that is, the video piece.
What needs to be considered for video is brightness, clarity, and size.
Regarding brightness: It is recommended to choose above 2000 ANSI lumens.
There are two parameters for brightness on the market, one is the ANSI lumen value (the brightness of the actual projection) and the other is the lumen light source (light source brightness).
Either way, the larger the value, the stronger the light thrown, and the clearer the picture.
So, the big one is the right choice.
About the clarity: It is recommended to choose a 0.47DMD chip, 1080P resolution.
Clarity is related to the display chip and resolution, and many merchants usually say that there are two kinds of resolutions: standard resolution and compatible resolution
The standard resolution must use a 0.47DMD chip to cast 1920 x 1080 pixels.
The compatible resolution is actually compressed, for example, the standard resolution of a projector is 720p, and the compatible resolution is 1080p. Well, in fact, it is to compress the 1080p video to 720p playback.
Therefore, when purchasing, be sure to ask what the resolution of the chip is, and the chip greater than 0.47DMD will be clearer.
About size: The larger the projection ratio, the larger the display of the same projection distance.
For example, the projection ratio in the projector parameter is 1.2:1, which means that a distance of two meters can project a 2.4-meter-long picture.
In addition to the above, the projector also has a messy selling point, such as diffuse reflection, anti-blue light and so on.

Selling point spit
Seriously, some selling points really don't know how the merchants came up with it...
Diffuse reflection ≠ eye protection
Many merchants say that their projectors are diffuse reflection under the guise of eye protection, so that consumers mistakenly think that it is really eye protection.
The truth is: all projectors are diffuse reflection principles, and there is no scientific proof that diffuse reflection is more eye-pleasing than television.
The brightness of the projector must be high to see clearly.
To say that the real "eye protection", Fei Mojun feels that it should be a large screen, can be viewed from a distance, and will indeed be friendly to the eyes.
Therefore, look at things to see the comprehensive, do not be fooled by the business.
Anti-blue light mode
This is actually easier to see through, because the TV also has an anti-blue light mode, mobile phones, computers have. Anti-blue light is not exclusive to projectors and does not have special marketing value.

The projector ≠ IQ tax
Many people say that projectors must cost a lot of money to buy high definition and good visual effects. So, think it's iq tax.
The truth is: all products have their use of meaning, projector screen is large, there is a sense of atmosphere, these advantages are indeed TV can not replace.
Unless you don't send money like Principal Wang, spend 500,000 to customize a 100-inch TV. The visual and sound effects are really incomparable to projectors.
If you want to watch TV again, and you want to watch a movie once in a while. Adults don't need to make a choice, it's better to pretend to be both.
Or install directly on the top surface of the TV background wall, without delaying the use of space.

Projector mounting
The projection type does not have to be fixed to the wall, there are also desktop and floor-standing types, which can be selected according to their own needs.
#固定式
#台式
#落地式
If there is a baby at home who likes to mess around, it is recommended to install a fixed type, the baby can not reach, it is not easy to destroy.
If you want to occasionally hide in the bedroom to watch a movie, it is recommended to move on the table or floor to facilitate movement.
The above is the knowledge point about the projector, and there is an unclear part of the lower right corner of the message comment ~
