For the projector, it seems that it only appears in the classroom and the conference room, and it always feels thick and big, but today, it has quietly and quickly entered our families and even university dormitories! First time on Love to play computer games When I saw the small home projector, I was deeply attracted by him because it was light and portable, because it could realize the function of a TV set! Thank Ainongji for offering the chance to try out Shenhua Xiaomei Projection TV. Without much nonsense, let's introduce some processes and feelings of the trial!

Xiaomei, Xiaomei! It sounds very friendly. First of all, my first impression of this product was very good.

For some time, many projection products have appeared in the market, and many manufacturers have always taken "high brightness, screen less TV, home theater" as the theme of publicity. While focusing on the sense of light and shadow, Shenhua Xiaomei emphasizes intelligence, portability, and micro projection, which are mainly aimed at college students, but in fact, this portable feature is useful for travel, business trip Marketing promotion also has many convenient conditions.

Specifications

Although it is a mini projector, Xiaomei's hardware configuration is good. The 1G RAM+8G ROM configuration is basically the same as the common set-top box configuration, but in fact, the 8G ROM is more generous than the 4GROM used by some domestic smart set-top boxes. In addition, the combination of Cortex A5 quad core CPU and Mali450 MP6 can easily handle the problem of multitasking. This configuration is particularly important when watching 4K and 2K videos.

In addition, Shenhua Xiaomei uses RGB LED light source and DLP display technology, but one thing is that the maximum brightness of Xiaomei is only 300 lumens. If you have to watch movies in the daytime, the brightness seems to be a little stretched, so it is necessary to close the curtains.

Appearance and accessories

▽ All accessories of Shenhua Xiaomei include: power adapter, Micro USB power cable, remote control (magic pen), HDMI cable, host storage bag and a set of special brackets.

▽ Xiaomei's appearance is very delicate, its size is about twice that of an ordinary mobile phone, and its body color is champagne gold, which makes people feel smart and beautiful.

▽ The front surface of its shell uses a nano UV panel and optical coating process, which looks bright and beautiful. In addition, this process can effectively resist fingerprints, and is easy to clean without worrying about stains.

▽ The bottom of Xiaomei is made of alloy. In addition to sticking labels such as factory parameters, a nut is designed to connect the bracket. The size of the nut is the same as that of the SLR camera. If you have a PTZ at home, it can also be used as Xiaomei's bracket, which is very convenient.

▽ The middle frame of Xiaomei is made of aluminum magnesium alloy. The main advantage of aluminum magnesium alloy is its high strength, which is mainly used as computer shell and aircraft shell. In addition, its weight is very light, which also makes the main engine of Xiaomei weigh only 235g, which is on the premise of 5700mAh lithium battery. In addition, a cooling air outlet is designed on the right side of the middle frame to discharge the heat generated by the machine during operation.

▽ Shenhua Xiaomei uses a dual lens design. At present, there are not many products using this design in the market. The main lens mainly completes the projection of the picture, and the sub lens is used to receive and monitor the picture information. At the same time, the dual lens design can achieve rapid automatic focusing. There is an air inlet between the two lenses, which can form a dual channel with the side air outlet for heat dissipation, to ensure that the equipment can discharge heat in time when working for a long time.

▽ Xiaomei's main lens uses the German OSRAM light source, and the lens surface is coated, but neither lens is equipped with a lens cover, so a big spender like me often leaves fingerprints on the lens surface.

▽ On the other side of Xiaomei, there are various main interfaces and power switches of the device, including HDMI, TF card, USB2.0 and a Micro USB.

▽ Xiaomei's power switch is of sliding design, which can be turned on by pushing it to the power side for three seconds. In addition, it can be turned off by pushing it to the side of the power sign for three seconds when the machine is turned on.

▽ But what we need to remind you is that Xiaomei charges when she is off or needs to enter the charging state when she is in use. She needs to turn the switch to the side of the battery sign when she is on or off.

▽ USB interface, power indicator.

▽ TF card can support 32G at most, which is enough for me to use. HDMI interface can connect laptop and other devices, which is convenient for office users. TF card slot and USB make storage expansion more convenient.

▽ Loudspeaker and 3.5mm headphone jack are arranged at the rear side of the fuselage. The black circle in the middle will be used to receive infrared signals in high-end products in the future.

▽ Xiaomei speaker is said to come from BMW audio brand, which uses high fidelity independent speaker and dual channel audio transmission. Through my own measurement, I feel that the sound quality is good, but after all, the size of the whole machine is there, and the size of the sound chamber, power amplifier circuit, heat dissipation and other issues should be considered, so I am personally satisfied with the actual sound effect, At the same time, Xiaomei also provides a headphone jack for highly demanding users. I tried my Bluetooth headset and it worked very well.

▽ Let's talk about Xiaomei's support. The main body is composed of two parts. The surface adopts anodic oxidation sand blasting technology, which makes it feel textured and frosted in the hand.

▽ The installation process of the bracket is very simple. It can be inserted directly according to the slot, but I always think that such two pieces of metal, always in hard contact, will wear out quickly, and the part with folding needs to be connected to the host before it can be put into the slot. After having weight, there is really a small problem with alignment, so I think it is better to add a little protection.

▽ The effect after the bracket is installed.

▽ One more thing needs to be mentioned. There is no anti-wear measures for the connection between the bracket and the host. My host has been worn now, and I feel distressed. The adjustable angle of the bracket is very large, which can easily realize horizontal and vertical projection. Moreover, the positioning of the rotating shaft is very accurate, and there is no noise when rotating.

▽ This picture is the effect of lying on the bed and projecting onto the roof.

▽ 10 key remote control, also called magic pen! The main function area is equipped with "return key, home key, zoom in key, menu key and OK key", and the left and right sides are designed with volume adjustment keys and power control keys. Here, the manufacturer is recommended to add brightness control keys to facilitate users to adjust brightness according to the environment at any time. In addition, the design of keys on both sides is not particularly convenient, and I didn't find the volume key at the beginning! After all, such a small remote control can be handled by one hand. There is no need to place it on the side, which also increases the cost. In terms of materials, the remote control uses nano UV panel material, built-in lithium battery, and gravity sensing, which can be used to play games.

▽ The quick charging of 3AH is very powerful, and it can be fully charged after a little more than an hour. However, it should be noted that this charger cannot be used to charge the remote control. The remote control must use a charger of about 500mAH. In addition, the HDMI and USB wires provided by the manufacturer are of good quality, feel and toughness, and can be felt at a touch.

▽ It is also equipped with a storage bag to store the host. You can also use this storage bag to clean the lens after you try it.

▽ But although this small bag can accommodate the host, there is no place for the bracket, and if it is placed outside the belt, it is easy to scratch the belt.

Actual use

After talking about so many accessories and details, let's take a look at Xiaomei's actual use effect. Now that we talk about use, let me first introduce the relationship between Xiaomei's picture size and projection distance. Although we can't pursue this distance in actual use, we should be aware of it.

▽ From the above data, it can be seen that when the distance is about 1.3 meters, the projection screen can reach 35 inches. This size is perfect. The upper bunk of the university dormitory can be projected onto the roof just fine. I think the lower berth can also see about 25 inches by pasting some white paper on the bed board of the upper berth. In addition, Xiaomei's focusing speed is still very fast. If the distance is about two meters, the focusing can be completed in three seconds, and there is no loss of focus or out of focus. However, if the distance is too far, the focusing time will increase to a certain extent. I observed that if the distance is more than three meters, the focusing time should be about five to seven seconds.

▽ In terms of the system, Xiaomei adopts PIQS UI2.0 based on Android 4.4.2. The main UI interface has only one screen, but it has designed a sub item navigation menu bar, so that users can clearly see the content and function categories, more like operating a browser. In addition, in terms of resources, Youku and CIBN dual platforms are adopted, and multiple TV broadcast channels are preset in the platform. In addition, various popular entertainment programs can be seen at present. In addition, movies and games can be directly entered into the corresponding options for personalized selection. Daily needs can be met, but the premise is that your network speed is sufficient.

▽ But for a person who likes to make troubles, such a UI does not satisfy me. In addition, for the built-in application market of the system, I would like to complain that the content is too little. So, in order to break this embarrassing situation, we can install third-party software. The specific method is to put these APKs in the U disk, and then choose to install them, Under normal conditions, the system cannot recognize the APK file in the USB flash drive. We need to make the following simple settings: enter the settings page, select "About Projection TV" in the menu bar on the left, and then use the magic pen to click on the "System Version Number" on the right page for more than 5 consecutive times to open the "Developer Mode", Then we can enter the "developer mode" and check "USB debugging". At this time, it is OK to install some of our commonly used live broadcast and on-demand software. But there is a problem. Due to UI restrictions, we can't directly put our favorite software on the home page. We can only enter the "application" page to view it, and some applications are not displayed here.  

▽ Fortunately, I'm clever. In the "game" page, we can find them by adding applications at the bottom. However, in the process of use, there were some small incidents. These applications did not respond when they were selected with a magic pen, and they could only continue to be used by adding new ones. Hum hum, with third-party applications, Xiaomei can be said to be an all-around girl.

▽ Xiaomei can also support the wireless projection function, specifically Miracast and Airplay. The connection mode is relatively convenient. The Android system's mobile phone can be directly connected, and the fruit machine can choose the "Le Tou" connection. But for me, this projection function is basically only used to view photos, because we have a third-party application, so we don't need to project the mobile phone's video.

▽ After talking about the UI, let's talk about the picture again. First, with Xiaomei projection, the lens must be perpendicular to the projection surface, or trapezoidal distortion will occur. In addition, because Xiaomei's brightness is not high and her lumen is only 300, it is not suitable for use in the daytime. After sunset, you can have fun with your sister, which is just in line with the work and rest time of the Student Party, except for the bracketed weekend!

▽ If the curtain is not pulled, the brightness is adjusted to the maximum, and the effect is not satisfactory.

▽ Now let's enjoy Xiaomei's performance under the best screening conditions. In the default settings, I have selected several pictures. From the contrast effect, we can see that Xiaomei is better at processing deep tone images than light tone images. Especially in the third picture, the display effect of beautiful women's skin is general, but the display of monochrome hair is good. In addition, Xiaomei's actual display effect is not as bright as the original picture, But the color saturation is very good. The blue sky, white clouds, grass and prawns are lifelike.

▽ In terms of video, Xiaomei's performance is very powerful, and she has done a good job in color reproduction (dark environment). At the same time, on the premise that the quality of the film source is guaranteed, the description of the picture details is in place, and the switching of the film's brightness and darkness and the scene change are smooth and natural, without the phenomenon of shadow dragging delay. Live broadcast and on-demand are OK, as shown in the picture.

▽ In order to provide some data support, Antu rabbit was specially installed on Xiaomei, and the color of Xiaomei was simply evaluated. The evaluation pictures are as follows:

▽ Xiaomei also has an interesting function called AR. The so-called AR is a technology that calculates the position and angle of the camera image in real time and adds corresponding images, videos and 3D models. The goal of this technology is to set the virtual world on the screen in the real world and interact with each other. Applied to Xiaomei, it uses its own dual cameras to identify objects in front of the camera in real time (currently only supports hands), and then maps the preset content to objects through CPU processing to display dynamic effects.

summary

Through the above introduction, I believe that you have learned more about Xiaomei, a divine painting. After this trial, I think Xiaomei is still very powerful in terms of application scenarios and functions. Personally, it is more suitable for business people and college students. First of all, business people can take Xiaomei with them on business trips. It is very convenient to demonstrate PPT for customers or work with them, In addition, college students can use Xiaomei to enrich their spare time life. After all, it is not convenient to set up a TV in the dormitory. With Xiaomei, they can use the wall in front of their desk, the roof, and even the upper bed as the projection curtain. In addition, it is also very convenient to flirt with girls on weekends. In addition, the Xiaomei UI is simple and convenient in operation. According to the method in this article, third-party applications can also be installed, with strong scalability. At the same time, it is also easy to carry out various operations with Shenbi. Over the past few days, I have also refined the advantages and disadvantages of Xiaomei for your reference.
