What is a Smart Projector? Simply put, it is a projector that integrates the display system, intelligent system and sound system. Because this kind of product is simple and easy to use, the screen size is large, so it is favored by consumers, looking at a lot of small partners who want to start with smart projection, they will not choose, Xiaoying to give you a focus Ha:
1. Physical resolution
Projector resolution is a very important performance indicator, we commonly have 1080P and 720P, of course, now many merchants are promoting 2K or 4K, but one really supports the quality of the projection equipment price is too high, and the second is that some are also the "consumption trap" of the business 2K, 4K is compatible with the resolution, and not really have such a high picture quality.
Therefore, it is recommended to consider the physical resolution of 1080P or 720P when choosing. Be wary of the "compatible resolution" slogan, because it indicates the resolution that can support the input signal, and there is no necessary relationship with the physical resolution of the picture, please look for the physical resolution when purchasing.
Second, the display chip size
At present, the intelligent projectors on the market mostly use DLP technology, which is the original technology of Texas Instruments (TI) in the United States, the core component is a DMD chip, and the chip size we generally say is the SIZE of the DMD chip.
DLP chips are divided into microchips and standard chips, DLP microchips have lower recommended brightness and size, suitable for small size and low power consumption applications; standard chips are designed for high brightness and high performance applications, is a better choice for buying home projection.
Directly say the conclusion, do not put the parameters, if you have a sufficient budget, it is recommended to give priority to the chip size of 0.47 or more products! Although many smart projectors are the same as 1080P, there are many articles, and you should pay attention to the size of the chip when purchasing.
Third, brightness
What we usually say about projection brightness is actually the brightness of the picture, and the appropriate brightness can make the picture clear and bright and comfortable to watch. At present, the brightness of the smart projector on the market is mostly about 1000-2000 lumens, which is also in line with the brightness of most consumer viewing needs, and there are about 3000 lumens upwards, which are used for larger size projection screens and brighter use environments, the price is expensive, and everyone usually does not use it.
Speaking of brightness, everyone should see whether the manufacturer's labeling unit is ANSI lumens in the purchase, if not, there is a risk of encountering false brightness, it is recommended to keep an eye on it.
Fourth, the lens and projection distance
When we buy smart projection, we often hear the word projection ratio, which is a value that must be paid attention to when purchasing. Projection ratio = projection distance / frame width. The projection distance refers to the distance between the projection lens and the screen, and the picture width refers to the left and right width of the projection screen display area.
When the family uses projection, it is generally recommended to start with 100 inches, if the living room or bedroom distance is 3.5 meters, the projection is intended to be placed on the back wall, removing the space occupied by the curtain and the fuselage, the actual projection distance is about 3.25 meters, and the projection ratio of 1.15 ~ 1.5 can meet the needs of use.
Before purchasing a projection, we first measure the distance between the front and back walls, combine the projection size, and then judge which projection is appropriate according to the projection distance table of the projection.
In addition to the projection ratio, you also need to pay attention to the material of the lens, the current lens material is mostly glass or resin, glass lens is less likely to appear than resin lens overheating focus and other extremely affect the experience of the phenomenon, it is recommended that you try to choose the projection of the glass lens.
5. Watch during the day
Projectors are different from TVs, as a product that can only achieve full scores when using the experience in low light, if you have the need to watch during the day, it is best to buy a blackout curtain!
Final summary: Everyone generally pays attention to the above points, and on the way to buy smart projection, it is rare to step on the pit.
