preface:

In my impression, the projector looks big and very heavy. I remember when I was at school, there was such a big guy in the classroom. The machine itself occupied a table, and it had to use transparent cards to project on the screen. At that time, I felt really tall. Later I learned that this was a slide projector. Time has changed. In this rapid development today, the popularity of the network also makes more new things and products come into being. This product introduced today is the current product. Its small metal body is more convenient to carry and has more texture. It is the latest generation of "no screen super TV" micro projection product developed by Jimi Technology - Jimi Z4 Beige.

As a matter of fact, the company has known about Jimi Technology since a long time ago. The company was founded in November 2013 and put forward the concept of "screen less super TV". Up to today, it has released a number of screen less super TV micro projection equipment, becoming a famous domestic intelligent projector manufacturer.

Let's get down to business. Let's take a look at the outstanding performance of this Z-series product of Jimi Technology - Jimi Jue.

Unpacking:

A good product will not be inferior in terms of outer packaging design. The packaging box in Jemime Z4 color is ingenious in design. The three-stage combination design well demonstrates the product concept of Jemime, "born freely".

The overall color matching of the packaging box is mainly matte black, and the golden waistline of Tuhao is distributed on the left and right sides, showing more dignity. The surface of the carton feels very good. The product code of "Z4" is drawn in large gold font. On the right side of Z4 is the Chinese name of the product. The ancient seal design of "Creak" seems to incorporate a little Chinese style.

In the first test of the packaging box, the source and characteristics of the product, the partners of Jimi and the product serial code of Jimi Z4 were identified in detail.

The three-stage splicing combination design is ingenious in any way, which makes me love it and can be collected as a handicraft.

The packaging of the inner box is also in black and gold, which is well coordinated with the product. Even the product warranty card and product instructions are printed in gold letters on a black background, showing a strong sense of dignity and business.

In terms of video experience, the official Gimi gave mango VIP members for one year. After starting up, you can complete the opening of VIP members by entering the exchange code on the back of the VIP card. You can watch all the VIP resources on the mango TV at will, bringing you an unprecedented visual experience.

Jimi Z4 Jazz has prepared a lot of accessories. In addition to the host, it is equipped with a multi-functional power adapter that supports fast charging, HDMI high-definition cable, and an all metal Tuhao gold multi-function remote control. However, Xiao Bian still feels that there is something missing. What is missing? Compared with the Jimi Z4 Evoque, there are indeed many fewer accessories. What about the Micro USB power cord for charging the remote control? However, in the era of excess smart phones, who would not have such a power line? It is reasonable to omit it. After all, it will not cause waste of resources.

Details:

The appearance design of Jemime Z4 Baron continues the design style of Z4 Air. The cuboid body adopts the same aluminum digging process as the Macbook Pro, and the high-quality Australian aluminum is used in the material. There is not a screw on the all-in-one metal shell. CNC cutting, polishing and other technologies have also been applied to the corners of the fuselage. Under the illumination of the light, the oblique section emits brilliant light.

The front black heat dissipation air outlet and the bottom of the fuselage are made of plastic, except for metal. The cooling air outlet is divided into left and right sides. The cooling fins can be seen through the plastic grille. The front air outlet is made of high temperature and heat-resistant plastic material, which effectively reduces the heat conduction of the heat sink. According to the data provided by the customs clearance official, the polar meter Z4 Jazz also adopts the graphene heat conduction design inside the fuselage. It can be seen that a lot of efforts have been made in terms of heat dissipation.

The surface of the case is frosted, and the golden color makes it more elegant. The mirror "XGIMI" logo carved by large laser is centered on the body. For a high and micro investment product that focuses on business office and entertainment portability, it is particularly important to control the volume and weight of the product. The ultra meter Z4 Jue color is 23.5mm thin and 0.65kg light. The lightness in volume and weight benefits from excellent design schemes and excellent materials.

On the right side of the front panel of the fuselage, the metal sliding switch is also extremely delicate. The surface is like a record texture, which increases the friction force. The sliding is free and the feedback damping is moderate. This switch design is very convenient in practical use. Slide to the left to start the camera. The green light flashes. Wait for a few seconds. The projection lens starts to work. Slide to the right to turn off the phone, and you will know it when you start. There is no need to learn.

The metal wheel on the right side of the fuselage is used to adjust the focus. The metal grille in the air next to the wheel is the air inlet, which is then circulated inside the body and then discharged from the front air outlet.

For a high-end micro investment product that focuses on portability, the interfaces of Jemime Z4 are very rich. From left to right, there are power interface, USB2.0 interface, USB3.0 interface in blue, current mainstream HDMI HD interface, and audio interface for connecting external speakers and headphones. The black button on the far right is used for mobile power switching. As Z4 Jazz is equipped with a 13600mAh large capacity battery as standard, it can become a power bank instantly by moving the power switch button. The iPhone 6S can be charged 4 times, and the iPad mini can be charged twice. In terms of viewing duration, it can play for 3 hours in standard mode and 4 hours in energy-saving mode.

The position of the indicator light is designed at the right corner of the rear socket area. The side feels flush with the metal surface. When it is turned into a power bank, the indicator light will turn green accordingly. When the machine is almost out of power, the indicator light will turn red. The opening next to the indicator light is the external playback chamber. When watching the movie, the sound quality is very impressive.

Compared with Z4 Air, the design process of the bottom of the fuselage is improved. The four corners are also equipped with rubber anti-skid pads, which can be placed on the desktop more smoothly and can also reduce noise. The Z4 color of aurora laser and other information are engraved in the center of the bottom. The bottom panel and the front panel have little reference in hand feel. Without four corner rubber pads, it is difficult to distinguish between the front and the back.

Laser pen effect demonstration

The all metal multi-function remote control of the Jemime Z4 is the same as the Jemime Z4 Aurora. The 12 button divisional design makes it easier to use. The frosted metal surface makes the hand feel double. The built-in high-efficiency battery is said to last at least three months after being charged once. The voice function on the remote control can be easily controlled by pressing and holding the voice key and saying commands. This design also brings more convenience to users in their daily use. It also has more powerful Bluetooth dead space free remote control, laser pen, electric focusing, gravity sensing and flying mouse functions. The reset key, charging interface and function switch are designed at the bottom of the remote control. This design preserves the aesthetic appearance and is more convenient to operate.

Startup settings:

After introducing the details of the fuselage, let's start the machine to have a practical experience. Simple system settings are required for initial startup.

The first is to adapt the Bluetooth multi-function remote control. At the same time, there will be voice prompts again and again to remind you how to do it. The adaptation tutorial is also very detailed. Press the Home key and the Back key at the same time. When the green indicator flashes for 3 seconds, the blue indicator flashes quickly. Release the key, the blue indicator lights up for 2 seconds and then goes out. The pairing is successful. If the pairing fails, wait for 30 seconds to exit and repeat this step again. The next step is to set up the network. The Z4 Jazz has a built-in wifi module that supports the 2.4G/5G dual band network mode. In the network setting interface, find your own network and enter your login password. The power on settings are also interspersed with the product features of the extremely cool Z4, such as turning into a power bank, switching between the business version and the standard version, and no screen assistant.

System UI:

Jimi Z4 Jazz carries its own GMUI, which is similar to the traditional TV box system. However, many features have been added to the projection function, which can give you a good practical experience whether it is for business or entertainment.

As the built-in system is in deep cooperation with Mango TV, the corner of "Mango TV" can be seen in the upper left corner of the main interface of the system. On the left side of the corner marker, there are shortcut keys for version switching, user login name, wifi signal identification and other information. The main interface is divided into two screens, consisting of large icons and small APP icons. The big icons are divided into four sections: film and television, music, games and applications. The small icon area is mainly composed of system settings, Lebo projection, resource manager, no screen assistant and other APPs. Such size icon plate division is easy to distinguish and find. Press the left key of the remote control to the leftmost side of the main interface, and the internal and external memory will be called out, as well as the fast switching of HDMI program source. You can also install third-party software through an external USB flash drive, press and hold the APP icon, or enter the function of moving or deleting.

resources:

Film and television resources:

The film and television resources are extremely rich. Due to the deep integration with Mango TV, click the "Film" section of the main interface to enter a sub interface, which is divided into two sections: recommendation and classification.

The recommendations are all popular TV dramas and movies. In fact, more content is under the category section, and the left side is the function area of search, collection and history. Search, you can search through the acronyms of movie names. You can collect your favorite movies and TV plays, which is convenient for watching movies and chasing dramas. The history function is the history of the movies you have watched. You can find all the TV dramas you have seen recently. If you want to delete them, just select and long press, and the deletion option will appear. Let's take a look at the film and television classification area. There are all kinds of films, TV dramas, variety shows, animation, documentaries, music and 3D films.

Mango TV:

The GMUI of Jemime Z4 Juice also has a built-in app of Mango Internet TV. Users can directly click to open it and enter the video resource interface. It is indeed very comprehensive. There are 23 categories in all sizes, but most of the content can only be viewed by open members. Users who buy Kimi products need not worry about it. It is very considerate that the official presents mango VIP members for one year. However, Mango Internet APP has too many restrictions for ordinary users and is somewhat impractical.

Music resources:

How can we live a boring life without music? What's more, with a hundred inch screen, the Jimi Z4 Jazz, does KTV still need to go to the concert hall?

The built-in music section is supported by resources provided by Baidu Music, which is similar to the film and television classification area, and is still composed of functional area and music classification area. Song resources are no inferior to film and television areas, which are divided into five categories: new songs, lists, radio stations, local music and special topics. Each category includes many small categories, which are also divided into several pages. With so many songs, it is estimated that they will not be the same after listening to them for a year. Blessed are the friends who like karaoke. It is a good choice to have a music party and set up their own karaoke workshop. However, considering the pursuit of better sound quality and the protection of the Z4 Jazz's external voice, it is recommended to connect the speakers when karaoke.

Game resources:

The built-in game section is relatively simple, and few are suitable for remote control operation. It is also divided into two major sections: recommendation and classification. In the recommendation section, I understand it as some fun and easy to use games.

In the game classification interface, there is only a search function, and the rest are game classification areas. It is mainly divided into eight sections: shooting flight, game hall, action adventure, chess and card games, racing sports, simulator, educational leisure and role playing. However, many games need Bluetooth game consoles to support them. Xiao Bian tried the game of "fight the plane". The remote control can be operated. On the large screen, the experience is very good.

Application resources:

In the built-in system, of course, the application store function is indispensable. The application section of the main interface plays such a role.

Open the application and enter an interface consisting of three categories: recommendation, classification and application management. The recommendation contains some software necessary for work and life. For example, WPS is indispensable for business people. Doctor Lilac can give us more health and medication knowledge in life. Headlines can let us check the news and interesting life events that happen every day. In the classified section, we can download and install APP software according to our own needs. However, compared with the "Dangbei market", its APP resources are not rich enough.

Of course, there are many software installations, so an application manager is needed for management. In the application management interface, you can download, update, and uninstall software.

System settings:

The setting menu of the GMUI system adopts a simple design style, which is very powerful. It is divided into network settings, Bluetooth peripherals, projection settings, general, user and settings about six categories. Among them, I can't help saying in the projection settings that the brightness of the projection lens can be adjusted here, which can be divided into five modes: custom, viewing, power saving, energy saving and highlighting. The user can choose five modes. When the power is less than 50%, the highlighting mode and custom mode cannot be opened.

In the custom mode, the brightness, red, green, blue and other parameters can be adjusted at will. There are more powerful functions, that is, horizontal correction of gyroscope, setting of projection mode and automatic trapezoidal correction. Among them, the automatic trapezoid correction technology not only supports the general up and down trapezoid correction, but also is equipped with the left and right trapezoid correction function only available for high-end computers of 10000 yuan, which brings users just the right viewing effect, and will no longer lead to the distortion of the image caused by the uneven projection due to environmental factors.

Demonstration of stepless zoom function

The stepless zoom function is also very powerful, which can scale the overall projection scale, and can also carry out individual vertical and horizontal scaling.

Explorer:

In the Explorer, you can view all the files stored on the local computer, as well as files on external storage devices.

For the convenience of users, the resource manager will automatically classify the stored files, which are composed of four categories: video, music, pictures and documents. If you still cannot find the files you need under these categories, you have to open the memory under all categories to search.

Business model:

Another feature of GMUI carried by Jemime Z4 Jazz is the exchange between the standard version and the business version. The standard version is suitable for entertainment viewing. The business version is suitable for those who work in the company. In the business mode, the icon layout of the interface is no different from the standard mode, except that the four icons of film and television, music, games and applications have been replaced by icons in four file formats of PPT, Excel, Word and PDF. The built-in WPS Office TV version software supports browsing various Office documents and most text formats, which can be easily switched through the remote control. In terms of hardware support, Z4 Juice is equipped with an HDMI interface, which can display the content on the computer on the large screen by connecting the computer host or laptop. It can be seen that Jimi is very considerate for business people. What's more interesting is that when you switch to the business mode, the WiFi network will automatically shut down and become a wifi hotspot. It is convenient for business people to connect with the Z4 Jueshe and transfer files to each other by connecting to the hotspot.

Product manual:

The GMUI system carried by Z4 Juice has a built-in manual function. Under the manual interface, each operation step has been carefully classified.

Users who are not familiar with the product can grasp the use method of the product through the APP function of the manual, which is very considerate.

Cloud backup:

GMUI system is really excellent in design and function integration, and also more user-friendly. In its system setting menu, there is a "cloud backup" function, which is really commendable. By registering an account in the Jimi community and official website, scanning and binding with WeChat, it can be used normally. Even if you restore factory settings or replace a new machine in the future, you can restore your previous settings and applications as long as you log in to the same account, which is very convenient. Although the "cloud backup" function is not a big deal today, it is very common on smart phones, but it is rare on micro investment products.

voice:

Jimi Z4 Jueshe is equipped with voice function as standard and adopts the voice engine of iFLYTEK, which has higher recognition and accuracy. It provides users with a more convenient search method. To find or open an app, just press and hold the voice key on the remote control to talk. For example, to query the weather, just say "weather". The speaker is a girl with a gentle and funny voice. There are more interesting functions for users to explore.

Lebo projection:

The function of Lebo projection screen is very interesting, highly playable and easy to operate. First, open the Lebo project app, scan the QR code in the interface that appears to add the public account, and then find the link to download the Lebo project app for mobile phone version to download.

The mobile phone and the Gemi Z4 Jazz must be equipped with the Lebo projection function at the same time, and can only be connected under the same wifi network mode. Experience the feeling of playing games on a large screen. It is not only shocking, but more exciting.

No screen assistant:

The Screenless Assistant APP is a very powerful APP software built into the GMUI system. It also opens the "Screenless Assistant" and downloads the mobile APP through scanning the QR code in the interface that appears.

After downloading and installing, open the software, and under the same network, connect through the scanning device. After the connection is successful, your mobile phone will become a super remote control. It can be controlled like a traditional remote control or used as a touch pad. Your fingers slide on the mobile phone screen. A "small hand" icon will appear on the screen less TV interface. Select the desired option and click OK, which is a bit like controlling a notebook. Also, like the metal remote control, it has the same voice function. Maybe you don't think these functions are important. Let's take a look at the functions in the treasure box. Focus, text input, screen capture, stepless zoom, and the same screen can all be controlled through mobile phones. In addition, there are also powerful and rich resource support. You can select your favorite video or music on the mobile phone, and push it to the screen of the super screen less TV through the same screen function. In addition, you can also install APP software remotely. I have to say that this non screen assistant APP is really a good helper you can't do without.

Performance:

In terms of hardware, Jimi Z4 Juesee is equipped with Mstar6A628 (Morningstar) TV class chip, Mali450MP2 image processor, 1GB running memory and 16G eMMC storage memory. Compared with the TV box, the hardware configuration is still very powerful, and the video parsing ability and 3D video processing ability are enough to cope with it. Xiaobian used mainstream evaluation software Anthare to test the video of Jimi Z4 Jazz.

The above results are obtained through testing. Among the 30 videos with different bit rates and resolutions, only 4 are not fully supported by Jemime Z4, and the number of fully supported videos has reached 26, which is still outstanding. Especially in 2K video, it can play smoothly.

The editor has made a broadcast test through the 2K source of "Kung Fu Panda 3" and the 1080P ultra clear source of "Iron Man 3". Under the playback of 2K and 1080P movie sources, fast forward or backward can respond immediately without getting stuck. In 3D video playback, when fast forward and backward operations are also performed, there is still no jamming or dragging. In addition, during playback, pressing the menu key will also call up the corresponding video setting menu, which can be used for 3D settings, subtitle hanging and downloading, picture proportion, image mode and other parameter settings. The operation is very convenient.

Sample comparison:

Jimi Z4 Jazz adopts high-definition coating lens, the display chip is 0.3 inch DMD RGB LED, and DLP technology is used in projection. The default resolution of Jemime Z4 Jazz is 1280X720P standard definition, but it is also compatible with 1080P and 2K resolution video output. The brightness uniformity value is 98%, the brightness reaches 250ANSI lumens, and the dynamic contrast is 5000:1. There are also 16 officially announced image quality enhancement technologies and 11 dazzle enhancement technologies. Even under the projection of a 100 inch giant screen, the image quality is still clear. So, what is the actual display performance of Jimi Z4 Jazz? Next, Xiao Bian compares the remake of the projection sample with the original picture, and the result is known.

Through the comparison of the above three groups of different proofs, we can easily see the difference. The white balance of the projection picture is generally blue, the contrast is high, and it is biased towards the movie style. The details are rich and there is not much difference from the original picture. Jimi Z4 Jazz has indeed made a deep adjustment in color performance. As a projection, it cannot be compared with the display after all. It is not easy to have such performance. If you can't get used to such colors, you don't have to worry about it. You can adjust the red, blue and green LED brightness through the custom mode in the system settings - projection settings.

Product overview:

As a member of the Jemime Z series, the Jemime Z4 is not so different from the Jemime Z4 Air in terms of exterior design, but has improved in details. The original sliding switch has also been retained. The light and thin body is also more convenient to carry. In terms of hardware, it is equipped with Mstar6A628 TV grade chip, four cores, graphics processor with 1Ghz main frequency, Mali450MP2, and 1G+16G memory combination, which also enable it to meet daily needs. The projection specification has reached the 720P standard definition level, and is compatible with 1080P and 2K video playback, but it does not support 4K movie sources, which is somewhat regrettable. The brightness is only 250ANSI lumens, and the daytime performance is relatively poor. The contrast is 5000:1. With the official 16 image quality enhancement technologies and 11 color enhancement technologies, the image quality is still clear at night even under the projection of a 100 inch giant screen. The super large capacity built-in battery can be transformed into a charging treasure through the switch button on the back of the body, which is very practical. In addition, it also has built-in trapezoidal correction technology for 10000 yuan high-end projection, which greatly improves the viewing experience of users. The Bluetooth remote control with rich functions also makes the control more interesting. Z4 Jueshe is equipped with GMUI system, with simple style design. Its content is also very rich due to the integration of video resources of Mango TV and music resources of Baidu. The business model specially designed for business people makes the operation more convenient and practical. As an intelligent micro investment product, Jimi Z4 Jazz performs very well in the actual experience. If you like it, you can pay attention to it and experience the visual shock brought by the big screen era.
