When I think of the black and white TV when I was young, it added countless unforgettable auras to my childhood. At that time, I always watched whatever TV was playing. I was sleepy and had to continue to watch. Later, I could easily watch movies on LCD color TV, projection panel, and now mobile phones. But the "impression" that black and white TV left in my mind was never found again. After more than 20 years of development, today's film viewing equipment has made great progress. From black and white to 2K, from picture tubes to ultra-thin liquid crystals, they are developing in the direction of intelligence and portability. Their purpose is also to bring better viewing experience to people's lives. Therefore, what you want to see on TV can be found, and TV has always dominated people's living rooms.

The maturity of display technology and process has also made TV the most widely used electronic product, but the difficulty of moving TV has also greatly restricted it. Therefore, as the product of the combination of TV and projection, no screen TV came into being. The screen less TV is widely accepted because of its small and changeable appearance, clear imaging, flexibility and portability. It may be a very competitive competitor of TV in the future. So today's display of the polar meter Z4 aurora is an iterative product with a unique appearance and many black technologies, Not only has the clarity been significantly improved, but also the trapezoidal left and right correction, which is only available in high-end products, has been added to continue the black glue style in appearance So whether the classics have been passed on, and what experience the new Z4 Aurora will bring us, please join me to experience it.

New ideas in packaging design

The package of Jimi Z4 aurora adopts cool all black packaging. The black packaging with gilded font looks very high-end, and the aurora tone halo in the middle also has a sense of design. In short, the flavor of the package is a special modern and elegant style, which makes people feel classy at a glance.

The appearance design of the Jimi Z4 Aurora package is high-end, but it is hard to work hard in the market. However, when opening the package, we found that the box was ingeniously designed as a three section folding type, which may be because it is convenient to take out the body and accessories from the inside of the package. In addition, a silk strap is designed on one side of the cover plate of each split box to open the cover plate in more ways. In addition, the gilded product logo on the gold high board is perfectly integrated with the black appearance, so a packaging design can absolutely affect the experience of a product, and can also reflect a company's attitude towards the product. "Great care" may be a magic weapon for Jimi to move to a dominant position in the non screen TV industry, The experience of brand new products from the outside and inside is also the attitude of this start-up company, which is worthy of our admiration.

Inside the Evoque package, 3D glasses, Evoque screen less TV and data cable power adapter accessory boxes are placed from left to right, and thick sponges are carefully added inside the box to fix the accessories to effectively prevent collision during transportation.

The accessories are rich and sincere

List more than ten accessories box hosts. It can be seen that the Evoque accessories lineup is strong. In addition to the host, it is also equipped with power adapter, data cable, tripod base, Bluetooth remote control, remote control charging cable, and manual security card. The focus is on the Evoque's main movie viewing experience, so it is mainly equipped with a mango membership card worth 720 yuan and two 3D glasses, From the luxury of accessories, it can be seen that the Evoque has a clear guide to the use and experience of the product. In addition, the remote control made of alloy material is much more high-end than the plastic remote control of the Z4. In the product iteration, the Evoque has dry goods and will never stir up cold food!

The front of Aurora still continues the style design of black glue. The layered design of black film and the main part of the following twilight gold makes it look like a retro art. It has a strong sense of impact in color matching. It has both retro flavor and modern design elements. No matter how it is placed, it can be perfectly matched with the surrounding homes, In the middle of the film is the logo of Jimi, and a power indicator light is ingeniously designed at the "stylus arm" position on the edge of the film, which increases the overall coordination of the appearance, and also means that the aurora sound quality has excellent performance.

3D shutter glasses are specially added to the aurora accessories. The plastic frame is sanded and comfortable to wear. The glasses will have 3D function after being opened through the top switch, and there is a mic USB port at the bottom to charge the glasses. At the same time, it can meet the needs of two people watching at the same time, so that you can easily see large films.

The remote control of Evoque adopts a full alloy body as a whole, and adds polishing treatment to the direction keyboard. The key layout has also been optimized again. The remote control connected by Bluetooth supports iFLYTEK voice, gravity, and flying mice, and has a built-in lithium battery, which can charge the remote control at any time. What I want to say here is that, first of all, the key layout of the remote control is very reasonable. The power key is concave to prevent accidental touch. The volume key is also changed from horizontal to vertical, and the innovative one is changed to oblique integrated key, which is more conducive to poor light or blind operation. The rubber material is also good for pressing the key, and the key range is also very clear; Bluetooth connection has been used by many high-end TV brands. Compared with traditional infrared, it has a stronger transmission distance, wider transmission angle, and more sensitive speed. Therefore, it has also been fully configured in accessories for the Evoque.

Quality of component mechanism

The narrow body design of the remote controller is more convenient for hand holding, and the radian processing frame also gives an excellent grip. The damping of the keys is slightly small, which means that the touch is coming. The remote control experience is very good, clear and sensitive with Bluetooth transmission.

When charging, it shares a mic USB charging cable with the 3D glasses. In addition to the charging interface, there is a Reset key and an Fn function key at the bottom of the remote control. There is a mechanical toggle switch next to the function key, which is the projection manual focusing adjustment button to be mentioned later. During the operation or charging process, there will be green and red light strips around the light ring of the power button at the top, It looks very classy and beautiful.

The appearance of Evoque is relatively round. The 196mm square round corner design has perfect unity in appearance and feel. The 50mm thickness and 1.2kg weight are also convenient to hold with one hand. However, due to its large size, it is not convenient to carry at any time. If there is a car, it can be ignored.

The most distinctive sliding power on key design of Aurora also has the effect of protecting the lens from dust, because the sliding switch is located at the bottom, and the thicker fingers may need to pick up the projector to operate. If the switch is set to L type, it may be more reasonable to leave a few paddles outside. The switch damping is slightly small, and the rear section damping is large, so the feel is ordinary.

Aurora has upgraded the lens again on the basis of Z4X. It adopts the international standard 600 ANSI high transmittance coated lens of DLP technology, with the contrast of 3000-5000:1, illumination uniformity of 98%, standard resolution of 1280x800dpi, and compatibility with 1080p/2k/4k 1280x800dpi. The above technical parameters also need special attention when we purchase projection at ordinary times, Large resolution brings clearer and more exquisite pictures, high flow brings more colorful pictures, and the key is the life of the bulb. Aurora uses Osram's latest dual light path s8 light machine engine, with a life of up to 3w hours.

Another interesting design of the Z4 Aurora is on the top of the vinyl record, which can realize the touch switch function, and can play and pause music in the WiFi speaker mode. In addition to these, the function of gesture control is also added. For example, you can cut songs by waving your palms from left to right at about 10cm above the record, and you can adjust the volume when your fingers rotate clockwise and counterclockwise. This kind of high power operation can not help but make people admire the quality and technological content of Evoque.

In addition to the excellent effect in picture quality, Aurora is not careless in sound quality performance. The exclusive sound system developed in cooperation with the well-known American sound brand Harman Carton, the dual channel stereo unit can be comparable to the desktop sound on the market, and the effect experienced in the viewing process through the irregular bee nest type opening design in the front is very good, It is enough to meet the family's daily demand for video music, and it can also be used as the main speaker without high requirements.

Aurora adopts an independent cooling fan design. The cooling blades are back mounted for heat dissipation. Compared with other brands, the effect of placing the cooling area at the bottom of the machine is much better. The internal cooling fins can be clearly seen through the cooling area of the diagonal strip opening. Open the lower bottom cover to see the cooling fan. The 10 speed regulating fan is the same as that in the notebook, The fan gear can be set automatically or automatically. In normal operation, the fan noise is almost inaudible, and the noise control is also good.

The interfaces behind are arranged orderly, including: LAN、USB 3.0、USB 2.0、HDMI 1/2、 The power interface, AV interface, headset interface and reset, and the built-in 2.4G/5G dual band WIFI and Bluetooth module of Evoque can support wireless and Bluetooth transmission functions, so it can be used at ordinary times to expand the free connection with the Wifi and Bluetooth external devices at home. Here, the addition of dual HDMI and USB 3.0 can show that Evoque intends to create a family TV without screen, The rich interfaces bring a variety of subsequent play methods.

The back cover of Z4 Aurora is removable. You can easily remove the back cover by unscrewing the three fixed screws at the bottom and rotating the chassis according to the arrow. After opening, you can see that a 2.5 inch SATA hard disk slot is reserved inside, which can provide large capacity memory expansion. With the built-in Thunderbolt remote download function, you can remotely control and download your favorite programs, Then it can be played directly after going back, and it has got rid of the restriction of no network.

The organization of the Z4 Evoque is basically the same as that of the Z4X, but the details and some features have been enhanced, but there is still no built-in battery to sustain the car. Since the main feature is In terms of carrying and business, is it more convenient to build a battery of several thousand milliampere hours, which is no longer limited by the conditions of office space, and can always add fun to the journey? Like Z4X, in addition to the whole entanglement, others mentioned above, whether from industrial design or using parts, Z4 Aurora has very distinctive characteristics and quality, So once you see it, you can feel that it is a sincere product. With so many appearances and configurations mentioned, what is the most important viewing function of the screen less TV? So let's move on to the next chapter - viewing experience!

The system is simple and smooth

The system of Jimi Z4 is based on the GMUI deeply optimized by Android 4.3. The logic of the primary and secondary functions of the interface is clear, and the intention of the UI designer can be seen in the animation effect and icon drawing. The style is simple and functional priority setting. The first screen is set with four commonly used main categories of music, film and television, applications, and games. The left and right menus are designed to use the right button to scroll over the screen, The list of downloaded applications displayed in the secondary menu determines the user's experience to a large extent for the movie watching products, whether it is non screen TV or color TV resources. Aurora has a built-in Mango TV and has given away VIP for two years, so Aurora, which relies on a third-party platform, does not show obvious advantages different from similar products, The game is also the Grape Game Hall that other products have always carried, so Aurora is excellent in system optimization, but the built-in resources are not very surprising. The software in the built-in application market is relatively poor. Of course, as an open Android system, we can download a sofa steward to solve this problem.

The system settings of Jimi are relatively rich, mainly divided into four categories: network settings, Bluetooth settings, projection and general settings, covering the parameter adjustment of all software and hardware. Users can freely set the corresponding options according to their own habits. Here, the key to projection settings is the free choice of LED brightness The four functions of projection mode setting (front mounting/lifting, supporting reverse projection), trapezoidal correction (supporting arbitrary correction of four dimensions of XY double axis), and stepless zoom are common on professional projectors, and ordinary micro projection is rare. In short, with these adjustments, no matter how you place the projection, you can correct the picture through parameter calibration; In addition, it is necessary to select the power on source. Because it is a dual HDMI interface, it supports the simultaneous access of two HD devices. However, the queue of the selected interface needs to be set again. It will be troublesome if there is no shortcut operation on the remote control, so this operation is really not scientific; What are the remaining screensaver settings, boot animation, input method Needless to say, it is different from person to person and you should choose according to your own habits.

The first time you start the machine, you need to pair and set the remote control. The intimate animation of Aurora and the text wizard can let everyone easily complete the initial setting of the machine.

Moreover, the GMUI system is also very perfect because the built-in electronic manual is very clear in classification, and also has graphic introduction, which is very clear.

The built-in focus reference image is very convenient for us to adjust the focus.  

The system can realize voice search by using separate voice keys with remote control

Aurora has 8GB built-in storage, and two USB 2.0/3.0 interfaces are also provided on the expansion device interface, which can support USB storage. The classification of videos, pictures, music, and documents in file management is clear at a glance, and it is also convenient for us to use in the business office environment.

The matching between remote control and the system is also perfect. In the background management, the application management is also realized by calling out the background through the home key, which is convenient for project switching and manual optimization of memory.

GUMI gives me the greatest feeling that it is comprehensive but not redundant, delicate but not cumbersome to operate. Apart from the need to strengthen the audio, video and store applications, others are impeccable.

Audio visual assistant synchronization experience

In addition to being able to operate the device with the matching remote controller, Aurora also provides a client function software - Jimi Assistant. It can be downloaded by scanning the QR code. The Kimi Assistant is a powerful APP. It not only has all the functions of the remote control, but also can select the content to play through the built-in page. The same screen is also a common function in business activities.

In the category of remote controls in the same screen assistant of Aurora, there are four categories. The first category treasure box can be used to control image adjustment and switch on and off. The options in it are often used and easy to find; In addition, the remote control function has a page for simulating remote control, which is slightly different from the key position of remote control, but it is not difficult to understand through the above marks; The touchpad is similar to the touchpad of a notebook computer, which is operated by touching and sliding the screen.

Other common operations

1. Correction of trapezoid

The trapezoidal correction is matched with the Fn button of the remote control, and the direction key of the remote control is used to carry out the trapezoidal correction from left to right, up and down. It is generally used to adjust when the projector is not perpendicular to the projection target. In fact, the operation is very convenient and simple.

2. Focus adjustment

The focal length can be fine adjusted according to the given focus reference. It is generally believed that the big and small letters in four directions are the clearest. In practice, it can be adjusted according to the picture pixels projected on the screen with the naked eye, which is also very accurate.

Video game experience

The Grape Game Hall carried by Aurora is very rich in resources, including chess, puzzle, shooting, cool running and other types of games, which are also very common. The feature of Aurora is that it feels fresh to play games on a giant screen, but I am not too impressed with the current TV projected games. I think the key control is not as cool as PC or host games, The game is also childish, not to mention the background of the game. It's OK to play casually at ordinary times. The sense of body can't be compared to the agility of the mobile phone's sense of body. The viewing angle also doesn't raise any sense of immersion, so the game runs smoothly, but it doesn't mean anything. Here, it doesn't just refer to Jimi.

After the long and detailed introduction of the Z4 Aurora above, we must have a very deep understanding of it. Then we should still return to the audio and video issues. After all, the screen less TV is more used to watch videos. Now I will compare multiple sets of original pictures with the projected live pictures (pictures with black edges), Show the effect of Aurora's 600ANSI!

1. Natural scenery

It is easy to see from the original picture and the live picture that the projection of the aurora is highly saturated and colorful on the projection picture, but the picture is obviously not as bright and transparent as the original picture, and the color restoration is relatively accurate. Since the camera is used to shoot in non professional conditions, the color inevitably has some deviation, but to be fair, it is very gratifying in terms of noise control and color.

The original details of the sky are better. The aurora quality of the dark details of the shadow on the right side of the building is poor, and the color of the building is somewhat distorted, but the overall grasp of the picture is still excellent, and the clarity is also very high.

The color of the flowers is still that of the aurora. Purple petals are matched with yellow flowers, and green leaves are used as a foil. It is hard to say which picture is better. It can only be said that the picture of the aurora is more pleasing to the eye, and the original picture is closer to reality.

2. Characters

It is not difficult to find in the sample picture of the character theme that the influence of the aurora projection is more blue and less warm, and the highlight is much inferior to the original picture. The overall picture lacks some flexibility and texture, especially some subtle color changes and some gradient effects on the task face. However, If you don't compare the original pictures and see the pictures of the aurora with the naked eye, you will feel that the pictures are clear enough and the colors are pure enough, so you are afraid to compare goods.

3. Others

Concluding summary

As a leader in the projection industry, Jimi has a good reputation and strong innovation ability. From Z4 Aurora, it is not difficult to find that it is a stray product. With classic appearance design, high-end hardware configuration and excellent audio and video effects, it can certainly be a benchmark product that sells well. The multi-functional Aurora has portability, simplicity Intelligent features make it easier to be accepted by the public. The unique Manhattan sound system, trapezoidal correction and dual optical path HD display comparable to the 10000 yuan projection, almost full format video support, and document office presentation can make it fully visible. It is not only fully capable of meeting the daily needs of families for video and audio, but also the unique document management function can make the office presentation so simple, I think the high cost performance ratio will also be favored by most people. Of course, no matter how big or small, no one is perfect. Here's a statement of what I feel is a pity in the experience:

1. The damping of the projected lens chamber cover is uneven, which does not support the lens machine to shut down/stand by with the lens cover closed

2. GMUI does not switch smoothly between business mode and movie viewing mode, and sometimes it restarts

　　 3. Resources are not rich enough and market applications are too few

　　 4. Without built-in battery, there are more restrictions on the use environment

        5. At present, the curtain must be closed in order to experience excellent effects in daytime watching, which cannot replace TV for the time being
