preface:

I have experienced many kinds of intelligent projection before, but after the release experience, I heard a lot of voices, including brightness, resolution, and lamp life. These problems are very important in the eyes of ordinary users. This time, I will take the opportunity to experience Nut P2 projection to talk about the very popular intelligent projection. At the same time, through the experience of Nut P2, Let's understand the current situation of intelligent projection.

appearance:

At the beginning, I opened a little more, and now I will formally introduce my personal experience of the nut P2 intelligent projection, The appearance of P2 must be able to see at a glance that the fuselage is made of metal. As for how good the metal material is, I think it is more meaningful to have a better texture. However, it was found later in the combination with the base that the metal is not only used to improve the quality of the whole machine, but also to adjust the projection angle arbitrarily through the base adsorption function.

In terms of accessories, Nut P2 is a simple accessory. It has all necessary accessories, such as 3D glasses NutP2 has not added the standard configuration, which seems to be the default of the current intelligent projection. From my personal experience with LED intelligent projection, users who like to watch 3D movies are still not recommended to use this intelligent projection. At present, the active shutter 3D technology has sacrificed some brightness, while the LED projection itself is not high in brightness. If you reduce the brightness, you can hardly see the details of the picture. It is not the original intention to appreciate 3D.

The nut P2 is mainly operated through the remote control, which is common in micro projection. It also supports the same screen control of the mobile phone, which of course requires the cooperation of the app. The conventional traditional projection will set physical keys on the body, which not only supports the remote control operation, but also supports the physical key pressing operation of the body. At present, the intelligent micro projection is not as good as the traditional projection, Perhaps it is because the micro projector body is too small to be used for body key control.

The design feature of nut P2 is the adsorption base, The nut P2 is adsorbed on the base and can be adjusted to an angle of 180 degrees. This angle adjustment is very convenient for putting the nut anywhere to project against the screen or wall. This design is very user-friendly for users, including me, when using nut P2. For example, the author has used the micro projection of Jimi and the intelligent projection of Shenhua. In terms of the convenience of projection, I think it is not as good as the design of Nuts.

The nut P2 can adjust any projection angle, including vertical upward, which provides great convenience for many users who want to watch ceiling TV movies in bed at night. The author has used the square intelligent micro projector before. If you want to project the ceiling in bed, it is a bit troublesome. You must find tools to fix the square micro projector upward to project the ceiling, The nut P2 does not need to be so troublesome. It can be put wherever it wants through the adsorption base.

of course This arbitrary angle projection of nut P2 will inevitably cause trapezoidal deformation of projection. To eliminate this deformation, The nut P2 has added automatic trapezoidal correction. The trapezoidal correction is not a new technology, but it can be said that it is very important for the automatic correction of nut P2, because it is a portable projection, which can change the projection angle at any time and anywhere, so it is particularly convenient to automatically correct the trapezoidal.

The nut P2 has its own speaker, which is very ingeniously designed. There are two loudspeaker units on the left and right to form a dual channel, which is better than the ordinary micro projection mono channel in terms of sound quality and stereo performance. Of course, it can't be expected to be better than the large unit stereo speaker, but it is better than the ordinary TV, micro projection and even Bluetooth speakers, especially in low-frequency, There are many senses of quantity, which can set off the film to a certain extent.

The external interfaces of nut P2 include HDMI for connecting computer host, PS4, XBOX game console, TV box, etc. The extensibility of HDMI is believed to be understood by most people. When connecting HDMI, nut P2 is only used as an ordinary large screen projection. Of course, many people like to play games with projection, Nut P2 can realize the game under the big screen. The other two ports are USB port and power port. USB is used to connect external mobile hard disk or USB flash disk. External storage content can be played directly through nut P2. The power hole, as its name implies, is used to supply power or charge P2.

Focusing experience: At present, there are three main focusing methods for intelligent projection, including traditional projection: 1. manual focusing 2. electric focusing 3. automatic focusing. Nut P2 uses electric focusing, which is much more than manual focusing, but takes a little longer than automatic focusing. Of course, focusing itself will not affect the user experience, but which is more convenient and which is more troublesome. Smart projection auto focus technology was originally only used in Shenhua products, while electric focus is often used by Nuts and Jimi. But NutX1 released this year also added auto focus technology.

Imaging experience:

The imaging effect of intelligent micro projection is the most concerned content for almost all those who want to purchase and use micro projection Nut P2 adopts a physical resolution of 1280X720, which is destined to be more suitable for playing online videos, The nut P2 is very good. As a large screen display effect for ordinary entertainment, the family sharing movie, TV, variety animation and so on are very good. It is like a large screen TV set, which can be put in the desired size according to your needs. However, if you really care about high-definition image quality, such as watching local movie files with more than 10 gigabytes, then the image quality of such micro projects cannot meet your requirements. But if you only watch online TV or something, NutP2 basically meets your requirements.

Brightness:

At present, most intelligent projections use LED light sources, and NutP2 is no exception. The brightness of LED light source intelligent projections ranges from 50 lumens to 800 lumens. This year, about 1000 lumens of LED projections have also been put on the market, typically 95% of NutX1 0 A NSI。 Is the 250 lumen brightness of nut P2 enough? Users who have not used LED micro projection have a lot of questions. The brightness of the TV has been adjusted to the maximum of 100 compared with traditional TV in full darkness

When the projection is about 40 inches, the brightness is roughly the same as that of the home 40 inch TV. Watch carefully and the TV is slightly brighter. Since the resolution of the TV is 1080p, the font of the TV is more delicate in the menu picture, which of course requires close viewing to distinguish. When playing network video, because the ultra clear film source used is actually 720p, the fineness of the TV is comparable to the projection performance, but there are relatively large differences in color, The color will be analyzed in detail later.

When the size of the projection picture increases, the brightness of nut P2 will also decrease, and the picture details will also decrease. The larger the projection size is, the darker the picture will be.

Bulb life: The concept of bulb life is still derived from halogen bulb projection, that is, traditional projection. The service life of traditional halogen bulb projection is about 2000 hours, and the attenuation is very obvious when it is used for about 800 hours. The theoretical service life of LED projection similar to nut P2 is 20000 hours, about 10 times that of traditional halogen bulb, which means that heavy users can use it for about 5 years, and light users can use it for about 10 years. Of course, this is only the theoretical value. Although it may not reach the theoretical value in practice, it will not be too big. At the same time, the theoretical attenuation value of LED light source is about 5% when it is 1W, which is very little compared with the attenuation of halogen bulb, and the attenuation is not obvious in actual use. Of course, all the parameters look good, but the fatal point is that the brightness mentioned above is not as bright as the traditional halogen bulb projection.

resolving power: Intelligent projection Last year, the resolution was generally 1280X720, which is one of the hard wounds of LED intelligent projection. However, the release of nut X1 this year has brought LED intelligent projection into the full HD era of 1920X1080. Of course, it will take some time to popularize 1080p, and the price is not as user-friendly as P2. Of course, the resolution of P2 is 720P, and many people complain that it can not reach the 1080P of traditional projection. In fact, if you understand it carefully, you will understand, 720P is sufficient for ordinary home users, because P2 is an intelligent projection, and resources are more dependent on online video. Most of the so-called HD of online video is only 720P resolution, and even some 1080P online video is only pseudo full HD with very low bit rate. The 720P resolution of P2 is just right for online high-definition video. Some people will come out and say that I only like to watch dozens of 1080P full HD videos of G size locally. I can only say that nut P2 is not suitable for you.

Content: Intelligent micro investment is based on Android system, and its built-in system is similar to Android TV and Android TV box, but the difference is that NutP2 has designed and optimized the UI of its own system, and the interface is similar to the UI of Sony handheld PSP, There is no problem with the UI itself, and easy use is the absolute principle. The icon menu selection is no different from the operation mode of traditional smart TV. In terms of content, NutP2 and iQIYI are combined. There are rich film and television resources, but there are a lot of film and television VIP content. With the trend of paying attention to copyright, major video websites are also increasingly paying attention to the maintenance of video copyright. Of course, like most Android smartphones, NutP2 can expand app applications by itself. For example, the author has downloaded several Android applications. In terms of content, due to the scalability of Android, there is no more to say.

Experience summary ：

The nut P2 has been used for a period of time, and has a good experience of its advantages and disadvantages. In terms of advantages, it can be projected at any angle and made of metal shell materials. The film and television playback time of about 3 hours is much longer than that of ordinary micro projectors, and it is convenient to carry. The brightness and resolution are basically enough for non full HD users. It is generally used at home, It's very good to watch under 80 inches of full dark environment projection. The disadvantage is that there is some noise in the heat dissipation, and the projection size should not be greater than 80 inches. Due to the limitation of brightness lumens, the 3D content is not good. In general, Nut P2 is a more practical mobile projector!
