First, select well-known projector brand
The HD home projector industry has not risen for a few years. As a young market, a large number of brands that only pursue high profits will emerge in the early days. These brands often appear suddenly and disappear quickly. For users who bought these projector brands, they faced the collapse of the company and no one was after sales.
At the same time, some companies that are somewhat well-known do not flash for a ticket, but they are limited by the company's own limitations and will continue to slow down at the pace of launching products. This type of projector brand due to the long-term squeeze by the first-line brand, over time, it will be difficult to guarantee that there will be no shortage of funds chain, long-term can not be profitable, and then cause the company to switch or even a direct failure of the risk.
In fact, now the technology of smart projection is not fully mature, although the projection product is not always a problem, but occasionally meet with some small BUG is still common. In this case, a good and stable after-sales service is a must. In this way, we can ensure that when problems occur in the products, they can be resolved in time so as not to make money. The advantage of well-known companies is that they can provide better after-sales services with their own strength. Such as Haier’s Xiaoshuai Cinema, along with the quality services of Cheng Haier, provide more secure protection. 
Second, well-known projector various parameters
The quality of the smart home projector is reflected in two aspects: First, the hardware configuration, which determines the quality of the viewing video, sound effects, the entire viewing experience; second, content, it determines the amount of video resources available, the system fluency, The ease of operation and so on. Let's look at the hardware first. The quality of the hardware is mainly reflected by product parameters. Well, it is very important to know what the various parameters mean.
The first is lumens. The brightness of the projector represents the brightness of the screen. The greater the number of lumens, the better the picture quality. Now, the overall brightness of smart projection is not very good, but high-end products can basically reach more than 1000 lumens, and it is completely satisfactory for home application scenarios. If you have high requirements on the screen, it is best to choose products with more than 1000 lumens. Xiaoshuo Cinema's new U3S HD home projector has 1100 ANSI lumens lumens. 
Second, the resolution. The resolution determines the picture sharpness. The current mainstream resolution of high-end home projectors is 1080P, which can fully meet the user's requirements for clarity. Some products support 4K source, but since there are few 4K sources, there is no need to pursue it. As for some 720P products, if people do not require high quality images, they may also choose to consider the price. 
In addition, the projection ratio. The smaller the projection ratio is, the smaller the projection distance required when projecting a certain size of screen, the more space is saved. For a user with a small living room or a less structured room, be sure to figure out the value of the throw ratio before buying, and make sure that there is enough space in your home to use the corresponding home smart projector. 
Finally, the sound. A good viewing experience is inseparable from the immersive hearing effect. Now the first-line smart projector brands are improving in sound effects, and their flash points are quite different, and generally do well in the treble and bass sections. However, here I would like to mention in particular that the U3S of Xiaoshuo Cinema adopts a separate sound design for the first time, which makes the sound independent of the machine. This unique design allows the smart projection's short board--subwoofer to achieve qualitative leap. 
Third, pay attention to the content
Content includes system and video resources.
The biggest advantage of HD home projectors over traditional projectors is that they can carry systems, support the download of various APPs, and enrich their content through the Internet. A good system can be compatible with more APPs, and it gives a smoother operation experience, and even gives people the feeling of using a screenless mobile phone. Take the U3S of Xiaoshuo Cinema as an example. It is equipped with an Android system and can be easily operated using a regular Android phone. At the same time, the deployment of more APPs means more video resources, more games to play, and more application scenarios. So, a good system is very important.
In addition, in addition to the video resources brought by various APPs, the first-line intelligent projector brands will cooperate with the film source parties to create their own content ecology. Xiaoshuo Cinema cooperated with the original film source party to create a cat-eye cinema, following the rhythm of the cinema, and constantly updated the latest videos, allowing users to take a step closer. The U3S of Xiaoshuai Cinema now sends members for 5 years. This means that users can save money for other members and easily enjoy the latest movies through Xiaoshuai's smart projection. 
Fourth, price
After everything is comparable, the cost-effectiveness of others is the last thing to consider. Now that the products of the projector brands with relatively good reputation are at the same level, ie, the parameters are almost the same, the price difference is not very great. However, overall, the products of Xiaoshuo's theaters must be a few hundred pieces lower. In particular, when Xiaoshuo's cinema starts, crowdfunding and other activities, the price is quite conscience. Xiaoshuo Cinema U3S HD home projector is currently in the starting phase, as long as 3999 yuan. Need to pay close attention to.
