Speaking of smart projection, high configuration, high price, high demand may be the first impression on most people. In fact, as far as the projector market is concerned, with the development of science and technology, the price of home smart projectors has long gone down from the altar. From the initial price of tens of thousands, the price dropped to thousands of dollars, but in the face of the market Spotty projectors, how do you choose a high-powered projector? I believe many people do not know, the following Xiaobian will give you some suggestions. 
Smart TV/box information can focus on smart TV information network sofa butler (http://), China's influential TV box and smart TV website, providing information, communication, TV boxes, smart TVs, smart TV software, etc. Answering questions.
Projection size
In terms of home entertainment, the most important soul of the projector is big! Screen! screen! With this, the excitement of any experience soars! !

So, the size of delivery is very important. Basically, a 1.2:1 projection ratio is sufficient. That is, we are referring to the golden ratio. This ratio can be thrown at a size of 100 inches under a distance of two meters and five meters. Therefore, there is no need to worry about the problem of small size units.
Delivery quality
The picture quality of the projector is very important, which determines the effect of the entire viewing, but the word “picture quality†alone is very general because it includes many performance parameters such as brightness, resolution, and contrast of home projection. and many more.

In fact, as long as the choice of home projector, the resolution is basically full HD 1080p, so mainly do not buy those marked with support for full HD, in fact, the native resolution of 720p, or even lower commercial projector. The brightness and contrast can reflect the performance of the projector, so this is also two important factors. The projector with brightness of 800-1000 ANSI lumens can already meet the need. Too high or too low will not be good and will damage the eyesight. The higher the contrast, the better. There are only a few hundred to one or one to two thousand to one. Most of the products are commercial machines. Don't think about it.
Hardware Configuration
Configuration above, now almost all 2G +16 G of memory, below this parameter machine speed will be more cards, trapezoidal correction, optical focus, auto focus, wireless screen and HDMI, USB and other commonly used interfaces These configurations have become standard , But relatively speaking, the projector with high configuration will also have a high price. In addition, the built-in influence is also an important parameter. It is recommended that you choose a brand sound quality that is better. No matter if you listen to music or watch a movie, you can enjoy the sound quality while you watch it.
price
The last step is the price, a good projector not only needs to satisfy most people's needs in configuration, but also wins over other brands in terms of price. In the past, home projectors were not cheap, and many of the 1080P products had 10,000 yuan. The average user may not be able to purchase them easily. However, with the advent of micro-projectors, the actual purchase price of the projector has been greatly reduced. Entry-level miniature projectors are currently priced at just $3,000, which is about the same as buying a LCD TV. Of course, this still depends on the individual's positioning.
The above is the content that Xiao Bian has arranged for you. Cool LTV thinks that R4 is designed for you to create a home smart projection, high cost performance, to 720P price of 1080P configuration, all aspects are in line with the requirements of home projection. Now Tmall/Jingdong has sales, search for cool music as the R4 can be purchased on the homepage.
