As we all know, with the maturity of projection technology and the decline of cost, there are countless products in the projection market. Large and small brands have targeted this cake and flocked to it. Lenovo has also projected, which should be a good news for everyone. As the leader of the domestic computer industry, Lenovo will bring us what kind of products with its deep core technology and R&D capabilities.

Open box appearance: simple and generous, highlighting quality

Lenovo's product is called Xiaoxin Projection, and its packaging is very simple. The T1 on the front should be the model of its first product. The red Lenovo logo is set off in the upper right corner, which is very eye-catching.  

From the side, the red cartoon mascot, Xiaoxin, gives a festive color. It is the logo of Xiaoxin throughout, and the boot screen will also appear. Big brands are not ordinary, and the design of products is long-term and comprehensive.

Product information, two-dimensional code, etc. are printed on the bottom of the packaging box, and the anti-counterfeiting work is in place. The energy efficiency logo on the upper right corner is not seen on the general projection, and the secondary energy efficiency belongs to the medium energy consumption.

The packaging box is designed as a heaven and earth cover. The paper box is very thick. The projection host is embedded in the foam pad, which is very stable, anti-collision and shockproof, ensuring the safety in transportation.

The thick base hides the mystery. Below the host is the accessory box. The accessory box is a drawer type drawing design, which can be separated from the host box independently. This design is very novel, and also brings convenience to storage.  

In addition to the projection host, Lenovo Xiaoxin also has a power cord and adapter. It has no built-in battery and needs to be connected to the power supply for use. It also has a remote control and two button batteries. The user manual and warranty certificate are complete. The VIP card can be obtained through Lenovo's first event.

Detail design: exquisite design, unique  

The appearance of Lenovo Xiaoxin Projection is satisfactory. Its body size is 20 * 20 * 4.5cm, which is relatively small in the same level of products. Now many projections have abandoned the original intention of micro projection to pursue brightness and sound quality. The body is becoming larger and larger, which seems more like sound rather than projection. Xiaoxin's adherence to principles and quality is fundamental.

Xiaoxin Projection adopts a process similar to that of Apple in appearance. It uses the same metal oxidation process as Apple. It is surrounded by aluminum alloy metal frames, and the top and bottom are 2.5D covers. Although it is not the glass surface of Apple, the skin friendly surface feels comfortable and smooth.

The projection corners are arc shaped, the top is flat and smooth, and the middle round hole is a touch switch. This is the on-off key of Xiaoxin Projection. The key is engraved with Lenovo LOGO, surrounded by LED breath lights. The whole design is simple and practical, and acts as a big brand.  

The front of Xiaoxin projection is a lens and a heat dissipation hole. The heat dissipation outlet is placed in the front. We usually sit behind or beside the projection to watch. The hot air can be discharged from the front without interference. The magnesium aluminum alloy housing is also conducive to rapid heat dissipation.

At present, the plastic lens (resin lens) used by the vast majority of micro projectors on the market brings about the out of focus and virtual focus of the picture. Xiaoxin adopts the DLP optical projection technology of Texas Instruments in the United States, uses the Schott glass lens imported from Germany, is equipped with a high temperature resistant metal lens barrel, and uses a unique efficient optical engine and an overall heat dissipation solution, which fundamentally solves the problem of out of focus and virtual focus of the projection. Although there is no lens cover, the scratch resistant glass lens can be wiped with a lens cloth.  

The powerful interface configuration interface is a must for a projector. All the interfaces of Xiaoxin are located at the rear of the fuselage. The two USB interfaces are USB2.0 and USB3.0, respectively. The USB3.0 transmission rate can reach 5Gbps, which can play high bit rate 4K video smoothly. There are also two HDMI2. interfaces, power interface, network interface, headphone hole and reset hole, which basically meet the common needs.  

The power interface is Lenovo's unique square interface, which is also the universal interface for most Lenovo models of notebooks. Like the Type-C interface of mobile phones, it has no positive or negative differences, and the plug on the power adapter also matches it. If you have a Lenovo laptop at home, the power cord can be replaced. Although the projection uses a 90W adapter, the 60W power supply of the laptop can also be used.  

Most of the current micro projectors have poor sound effects due to volume constraints, and they often need external speakers to solve the problem. In order to provide high sound quality, Xiaoxin is equipped with titanium alloy diaphragm speakers on both sides of the fuselage, which balances the coverage of sound field designed for stereo effect.

The bracket at the bottom is Xiaoxin's exquisite design, which is also Apple style. The aluminum alloy bracket can be rotated to adjust the angle of the projection fuselage.

The center of the bottom is a standard screw opening, which can be adapted to the tripod. The support is circular and hollow in the middle. This design is also carefully designed. It just contains the components on the top of the tripod, which can be fixed stably. The plastic washer on the support is also conducive to anti-skid and wear prevention.

Most of the projections on the market seem to have no way to adjust the angle when placing the desktop. It can be said that Xiaoxin's adjustment of the angle through the bracket is an innovation. The positive and negative 10 degree adjustment of the angle can easily adjust the position of the placement angle.

Xiaoxin's remote control is also of the same style. The design of the arc is smooth and round, and the design of the control keys is simple and reasonable. The top is the open key, the five way key, the middle is the Home key, the return key, the volume key, the menu key, and the mute key. The most distinctive key is the side key, which is the focus function key. When you move it upward, the adjustment function is turned on, and the volume key is replaced by the focus key, The design is very ingenious.

Xiaoxin remote control is a Bluetooth remote control, which can avoid being blocked, has a wider control range, and is sensitive to touch. It is very convenient to operate with one hand.

The button battery is placed in the middle of the back of the remote control. The rotating hatch cover is slightly raised, and there is also a mystery hidden. It just matches the sinking of the power on button on the top of the host. The two can be magnetically bonded. The integrated design of the remote control and the host will never worry about not finding the remote control.

Scenario application: short delivery distance, wide application scenarios

The positioning of Xiaoxin Projection is a screen less TV in the home, which can be placed in the bedroom and living room. It is convenient to move and has a large viewing screen, which is suitable for large families.

It can also be suitable for renters. If it is inconvenient to move when buying a TV, a portable small new can completely replace a large screen TV to meet the visual enjoyment of renters.

The current projection is based on the 100 inch screen, but the size of the projection screen is related to the projection ratio. Because there is no official product parameter, when I actually measured the 100 inch screen, the projector needs 2.3-2.4 meters away, and the projection ratio is about 1.2:1, which is ideal among products of the same level.

Xiaoxin Projection adopts manual focusing. Although it has no auto focusing function, it is adjusted by remote control button, which is also easy to grasp when fine-tuning. Trapezoid correction has automatic and manual adjustment, and can also adjust the screen to the best angle.

Picture quality performance: ideal color performance, high brightness and high resolution

We use the 4K TV test chart to see the image quality performance of Shin Sing. From the color performance of the screen, each color shows saturation, rich sense of hierarchy, smooth and smooth edges. From the spherical diagram, the color transition on the gradient diagram is relatively soft. From the color distribution diagram, the triangle area is obvious, and there is basically no confusion.

In the restoration of tonal levels, the gray scale is basically clear and discernible, without skipping and merging. The 21 levels of gray scale in the spherical graph can be distinguished, and the gradient graph is also round and soft.

Xiaoxin uses the S8 optical mechanical engine. Lenovo and Texas Instruments optimized the opening and closing timing algorithm of LED tricolor lights. While ensuring color saturation, the brightness was further improved to 700 ANSI lumens, which is already good in micro investment of the same grade. The contrast between opening the curtains and closing the curtains in the daytime shows that the brightness difference is not too large, It is acceptable if you watch it in the daytime.

Xiaoxin's projection resolution can reach 1280x800, which is related to its high-quality glass lens and high temperature resistant metal lens tube. From the above figure, the picture is very clear and the image performance is very smooth. Although the light in the next picture of currency is not very strong, the stripes on the paper currency are clearly visible, and the small bill figures can also be accurately identified.

The screen shot effect will be affected by the ambient light and camera performance, and the actual viewing effect will be better than the screen shot. From this picture, the light is bright and dark, the delicate skin color of the girl in the light and the shiny fur of the dog are very realistic.

Still life drawing is also the best way to see skills. It has rich colors, different materials, and light and shade. The projection effect of Shin chan fully magnifies these features.

UI and resources: rich content resources, and the Tiger Mother mode is more intimate

The UI interface of Xiaoxin projection is also fresh and natural. It does not use cool colors. The columns are classified clearly, and it is easy to find the required columns. The interface scrolls left and right, instead of the popular waterfall type, which is more concise. The scrolling trailer on the top left is the usual style of Best Buy, but the font on the lower column is smaller and not eye-catching.

In addition to the column display on the home page, the UI interface switches to the application and settings page, which focuses all functions here. If the installer will add itself to the local application, it will not increase the page display. The most commonly used applications are displayed below. Functions such as music, screen projection, and office work can be called directly and conveniently.

From the projection settings, we can see that Xiaoxin Projection is divided into viewing, highlighting and user-defined brightness on the brightness display. It has the functions of automatic trapezoidal correction, stepless zoom, horizontal and vertical zoom, etc. The sound effect mode is divided into music mode and power mode, which can meet our various needs.

Now is the era of content as the king. Without the provision of resources and content, no matter how high the hardware configuration is, it will be limited. Only the provision of rich content can firmly attract users. Xiaoxin provides more than one genuine content. It integrates 80w hours of genuine content from iQIYI and BSTV, which can be updated synchronously every day.

Shiyun Cinema has a lot of content, including rich 3D movie sources, Kiwi Fruit Area, Rainbow Concert, etc., as well as numerous sports programs. The movie sources are updated in a timely manner. Although most of them are charged, they are still worth the money.

It is also very convenient to search for movies. Finding the movie title or person name of the desired movie source through the virtual keyboard is a bit cumbersome now. It is recommended to add voice search function to the remote control to make it more user-friendly.

Music resources are also very rich. In addition to the music channel in its own resources, QQ music is also pre installed to listen to music on the projection. Most of us like to watch MTV or concerts. The effect of the 100 inch screen is very good, as if we were in the scene.

Xiaoxin's built-in app store is Le Store, which is one of the largest and most comprehensive Android software download stores in China. The most important one is Lenovo's own store, which can be perfectly matched with Xiaoxin through customization. In this way, we can install more applications through the store. Of course, if you need to install third-party software, you can also install it through external storage, but it will take some trouble due to restrictions.

Xiaoxin also has a unique function, which is the tiger hemp mode, which is an application developed to protect children. It can automatically switch to the eye protection function to protect children's eyes, automatically isolate bad content, control children's viewing time, and we can be more relieved to use such a projector for children.

We can set the information and functions of children, so that the resources provided by the app can better match the age of children. The programs in the app are targeted and healthy. It seems that Xiaoxin has become a special projection for children.

At the time of control, Xiaoxin will automatically quit the play mode and need to remove the password to continue watching. This is very effective for children without control. We don't need to worry about keeping Xiaoxin with children during the holiday.

Playback experience: excellent decoding ability, good audio-visual effect

Xiaoxin Projection can project a large screen of 300 inches, but it is limited by the conditions at home. It uses a 100 inch screen, but this scene is also shocking. In addition to its high-quality audio, it has completely achieved the effect of home theater, which is unmatched by ordinary television.

Xiaoxin Projection adopts a 64bit quad core processor designed with ARM V8 architecture, a 1.4GHZ main frequency, a Mali450MP4 (4+2) 6-core GPU, and supports full 4K format hard decoding such as H.264, VP9, and H.265. It can basically eat most 4K movie sources.

Through the test of video format, 24 out of 30 samples fully support, 4 do not fully support, and 2 do not support. The excellent performance of the test is also rare in other projections.

After all, the software testing is limited by the source library, so we still need to pay attention to its actual decoding and playback capability. This is 20 4K high-definition video clips with different codes, code rates and frame rates for testing. According to the actual measurement, there are 2 sets with sound but no image, and only 1 set cannot be played. After all, this is the source of testing 4K high-definition TV. Xiaoxin Projection can perform so satisfactorily.

Some people may not be aware of such a result. As a professional high-definition video player, the decoding ability of the same sample source is far inferior to that of Xiaoxin Projection for the test result of Kaifeng Boer H10.

Lenovo Xiaoxin has powerful computing power and image processing ability. Its powerful 4-core CPU, high-performance 6-core GPU, and its unique image quality adjustment technology make the film's image quality and color details have excellent performance. When the picture moves quickly, it is clear and smooth, without dragging or dropping frames.

Xiaoxin Projection uses the same active shutter 3D imaging technology as DLP Cinema movie projector, which is brighter and more stereoscopic than ordinary dual polarized 3D cinema. It can play 3D movie sources such as left and right format, top and bottom format, and automatically synthesize 3D effects. The system also has its own 2D to 3D function, which gives us more options.

The actual playback effect is good. The 3D picture is very shocking and the stereoscopic effect is realistic. Unfortunately, the product does not come with 3D eyes, and users need to purchase them separately.

Xiaoxin Projection is not only a screen less TV, but also a high-quality Bluetooth audio. You can connect your mobile phone, tablet and PC wirelessly through Bluetooth to play local music easily. In its power off interface, it provides the option of using Bluetooth audio. At this time, the projection lens will be turned off and become a separate speaker.

Xiaoxin speakers use titanium alloy diaphragm, whose sound quality is no less than that of ordinary bluetooth speakers. Its tri frequency is relatively balanced, and the details are also very good. You can clearly feel the magnificence and clarity of the mid high range. The bass part also has a deep and transparent feeling, which also guarantees Xiaoxin's need to play in the home theater as a screen less TV.

The function of mobile phone on the same screen is almost available to WeChat investment, and Xiaoxin is no exception. It can use DLNA Miracast and Airplay are used for the same screen of mobile phones. Xiaoxin has also pre installed Lebo projection screen, which makes the same screen more convenient. Pictures, videos and documents on mobile phones and tablets can be easily put into projection for playback. In home applications, it is also fun for a family to watch photos on mobile phones.

Other tests: excellent overall performance

Xiaoxin Projection supports 2.4G/5G dual band WiFi, which allows us to have an additional choice. Most of the current routes have 5G signals, and the transmission rate is faster and more stable.

Connected to 2.4G and 5G signal channels of the same routing, 5G wireless transmission speed has obvious advantages, which plays a great role in our smooth watching of ultra clear TV.

I have used more than 10 types of micro projectors. Due to the limitation of the body size, most of the current micro projectors have poor heat dissipation effect. However, the heat dissipation performance of Xiaoxin's projection is unexpected despite its small size. After five hours of work, there is almost no heat around the body. The temperature of the air outlet in the front is higher, and the contrast before and after work is only 9 degrees higher.

Xiaoxin's working noise is also surprisingly small. Compared with other projected whirring fans, it can almost be regarded as silent. It is only 5 decibels higher before and after work, which can basically ignore the impact of this aspect. It can be seen that Lenovo products have a profound foundation, which is unmatched by other small brands.

Evaluation summary

Through experience, the highlights of Lenovo Xiaoxin are obvious. The body design is fashionable and noble. All glass lenses do not lose focus and do not lose focus. The integrated design of aluminum alloy bracket and magnetic suction remote control makes people refreshing. Powerful interface configuration, high-performance hardware configuration, high-quality Bluetooth sound function, and Lenovo Group's strong technical strength support, It can be said that it is a screen less TV with excellent sound and color, which is a wise choice for our video lovers.
