In recent years, although the projector is no longer the "high-precision instrument" in the past concept, for most people, the contact with the projector is still far less than other IT products such as mobile phones and notebooks. And home projectors are only a few people's playthings, in addition to the players themselves in a family, I believe that few people will use the projector.
The rustiness of the projector has caused many misunderstandings in the process of purchasing the projector. The result of being confused by JS will affect the projection quality, and even the entire budget will be floated. Below we summarize some of the major misunderstandings in the process of purchasing a projector, including not only the description of the projector parameters, but also the precautions in the store. If you do n’t want to be fooled by JS anymore, then read on.
Not all projectors can be used at home
This is the most common tactic used by JS Fool consumers, nothing more than to promote the brands and models they represent. In fact, there is still a clear difference between business machines and home machines. It is like cars divided into business cars, family cars, SUVs and so on. First of all, in terms of appearance, in recent years, with the gradual heating of home appliances, many businesses have also begun to focus on the development of molds to make the projector more in line with the home environment. This has been done in other product lines in the past with brands that are famous for industrial design It ’s better to get it right first.
Secondly, in terms of performance, one of the major differences between commercial and home machines is the choice of brightness. According to the imaging principle of the projector, brightness and color performance are a contradiction. Therefore, most business models sacrifice the overall performance of the screen in order to improve the brightness, but the home machine is different. Because most of the environments of home machines are dedicated audio and video rooms, the control of ambient light is in place. Therefore, the brightness of general top home projectors does not exceed 1000 lumens, but the brightness of mainstream commercial machines is around 2500 lumens.
Although in recent years, with the increase of entry-level home appliances, in order to adapt to the poor shading environment such as the living room, businesses have increased the brightness a lot, but the brightness of high-definition home appliances generally does not exceed 2000 lumens.
The next step is the configuration of interfaces and menus. Commercial and home projectors are also different. As far as the interface is concerned, home machines are often equipped with HDMI interfaces, some even more than one group, and some models of commercial machines are equipped with a USB interface for user convenience, whether it is DisplayLink or USB direct projection.
