Preface

We are familiar with "Z4Air Intelligent Projector" and "Zimi Mango Xiaomi",

This time, through personal experience, the author will present you a beautiful man with 360 degrees of appearance -- Jimi Z4X;

As far as the overall feeling is concerned, it is not only the Huadan of Jimi Family, but also a powerful+idol beauty man in the projection world;

Let me tell you something about this

Jimi Z4X, with its beautiful posture, is a new challenge and subversion to projectors of the same competitive level from the outside to the inside.

The vinyl record like top design (with high-energy gesture control ability, 32 likes), combined with the square design, looks like a record player, and the overall appearance has considerable visual impact.

However, the internal comprehensive capabilities of extremely colorful images, ultra-high audio quality, local storage, wifi connection, intelligent systems, office extension, etc. cannot be underestimated.

It is the so-called retro style to pay homage to the classic, and the avant-garde function surpasses the tradition; This classic appearance and advanced performance is just the opposite of the conventional projector, which has the same shape and conservative functions. People have to respect the courage and achievements of inheritance but bold innovation.

It shows that Jimi Technology is responding to the call and pace of national scientific and technological innovation, and is trying to or has begun to lead the trend.

I have used about ten types of projectors (including adjustment, maintenance, management, etc.), most of which are used at work and occasionally to watch movies (but it is troublesome to connect computers, speakers, etc.). Because they are basically traditional series, they feel a bit of sameness.

As we all know, there are many aspects to pay attention to when purchasing a projector, such as appearance and shape, lamp life, heat dissipation performance, sound and noise, professional scope, etc. How are these factors reflected in the Z4X?

In fact, when I received and used the super flat screen TV of the Jimi Z4X, I really couldn't put it down and had to say that Love is trapped here ！

The author thinks it is expressed in six words "Small stature, big ability" It's quite accurate.

Let Z4X show its skill, interpret the six character comment, and show the “ harmony but not sameness ” 。

Take a breath of fresh air outdoors, and then enter the text

Appearance appreciation:

Full family photo of Jimi Z4X:

Jimi Z4X and accessories: Jimi Z4X projector, remote control, DC variable voltage power supply, instruction card, mango TV membership card, triangle (the bottom of the installation machine is placed on the tripod for use).

1. Top ：

It looks like a vinyl record, and also has texture matching (as will be mentioned below, its ability is more than just like a record). The middle part is a jimi LOG (with the function of touch to open music). There is a red strip similar to a stylus on the upper left edge of the record. Surprisingly, it is an indicator light, but this small detail design has the effect of finishing touch, The matching is conspicuous and reasonable. It is located on the overall white square fuselage with the record, simple and generous.

2. Bottom ：

It is also a black disc designed bottom bracket. The knob can be loosened to disassemble the chassis or slightly adjust the height. The chassis edge has a large air outlet (mainly for cooling the hard disk and the whole machine); The chassis can be manually opened by rotating clockwise according to the arrow, and then a 2.5-inch mobile hard disk space can be seen (non-standard, self purchased), which becomes a resource machine with local high-capacity storage. You should know that local resources are the way to imagine when there is no network or the network environment is poor.

3. Tail end ：

All the interfaces are arranged orderly at the end, providing one network LAN interface (wired access is more stable than wifi), two USB interfaces (blue 3.0, black 2.0, convenient access to USB flash disk and other devices), two HD HDMI interfaces (everyone knows that the HD interface for simultaneous transmission of sound and image is a must for large pieces of equipment), one AV interface (the gospel of the old device interface) One standard 3.5mm headphone interface (SPDIF coaxial output design), the other is the RESET reset pinhole and DC power access port, and the left part of the tail end is a powerful heat dissipation vent.

The sharp eyed students may have found that, yes, the whole machine does not have a VGA interface. However, it is easy to understand that VGA cannot transmit sound, while the Z4X supports wireless connection and provides HDMI interface. Today's notebook or desktop graphics cards basically support HDMI interface output, and HDMI interface is not only clearer than VGA interface, but also has the function of simultaneous sound output, which is unmatched by VGA.

PS： The purpose of each interface is briefly explained. It is prepared for friends who don't know it. The god can ignore it.

four front end : It was written at the end of the appearance appreciation chapter because the front end is the focus of the focus that is valued by the public:

4.1: Lens -- double light path optical engine

The sliding cover is designed to open the lens (it is also a start switch). The Z4X lens uses a high transmittance coated lens (a lens material with increased transmittance on both sides, and the transmittance effect reaches more than 98%); The optical engine with dual light path design is used inside the lens for the first time (in terms of physical optics, it seems that the dual light path is about the polarizing beam splitter, polarizing beam splitter, lens and other components together to make the transmitted light and reflected light have a higher transmittance, but the used projectors have not yet encountered this technology, which is also said to be the first application by the Chinese government), According to the official data, the brightness is 30% higher than that of the Z3S.

Display technology: 0.45 "DMD RGB LED. I want to talk to you about it here. In fact, it is not just about display technology, but also about 0.45" DMD While RGB LED refers to the light source technology, that is, red, yellow and blue LED lights. It should be said that not only some model numbers represent performance, but also the comprehensive situation of light path power, overall power, heat dissipation and other factors, as well as the adjustment of the brightness and mode of the bulb, finally contributed to high brightness and quality products.

In addition, according to the service life, the projection lamp will be darker than the initial use, which is also the reason why the projection lamp has a service life, just like the bulb.

It is also worth mentioning that the Z4X adopts the DLP projection technology of Texas Instruments (the world's most advanced manufacturer of analog circuit technology components, especially the world's leading semiconductor technology in Texas, the United States). Now the projectors of RGB LED light source technology are basically using DLP projection technology, which is also the mainstream of the market, so this micro project is really unusual, Jimi is also a good product made of high-quality materials. The sound quality mentioned later also confirms this!

Brightness, as one of the main indicators of projectors, has always been of great concern. The official data of the brightness of the polar meter Z4X is 580ANSI lumen single lamp (ANSI is a measurement method in the United States as the standard measurement unit). Combined with the above lens materials and technologies, it is truly unique in the field of micro projection. What is its performance? See you later!

4.2: Sound -- customized by Harman Carton

From the intricate pinhole distribution on the right side of the front end of the Z4X, as well as the obvious brand logo on the upper right corner, plus the previous understanding, I understand that this is where the famous brand audio is located. It is estimated that many people know that many Mercedes Benz's audio systems are from a man named Harman/Kardun This is an American company specializing in manufacturing top quality audio. The reason why this brand is mentioned is that this "Jimi Z4X" speaker system was customized by Harman Carton's team, and it is a dual channel design. At the same time, combined with Texas Instruments' low distortion power amplifier, it has created a top quality sound effect of Jimi Z4X. The projector even has a sound, but it is still high-end, This is not cool enough!

5. Appearance Conclusion: After a series of appreciation of the appearance and hardware quality before and after the above pass, I believe that every friend who likes technology and digital will think that the Jimi Z4X is indeed a beautiful man with 360 degrees of appearance and strength, but his inner beauty will be more charming. Please go to the performance test chapter to learn more.

Performance test:

The combination of appearance design, hardware quality, operation configuration, intelligent system and other aspects of the Jimi Z4X is a new attempt, which is refreshing and impressive.

The following will test the performance of the above hardware configurations:

First throw out the list of system parameters and configurations:

1. Startup test ：

The slide cover is powered on for 8 seconds to enter the system display screen, and 17 seconds to enter the system and complete the wifi connection. This boot time is quite powerful. It is about 5 times faster than the boot speed of traditional projectors. It takes half a day for traditional projectors to light up just by starting the bulb...

2. Temperature test ：

When testing the operation and heat dissipation temperature of the whole machine, the author made the machine run for one hour first to test the air outlet temperature (theoretically, this is the hottest place), and the displayed temperature is 40.2 ℃ (the measurement accuracy deviation of the temperature sensing gun is ± 1 ℃), which is enough to show that the heat dissipation performance and temperature control are good, different from similar projection products.

In addition, when the author tested the cooling performance of the Z4X when it was powered off, the cooling system was shut down immediately after the shutdown (thanks to the good temperature control cooling performance), which is very good. We all know a common sense about the projector. Normally, after the projector is turned off, the fan will rotate continuously to dissipate heat until the temperature of the bulb and the machine drops to a certain temperature. If the projector cannot be turned off, the power will be cut off immediately to prevent the bulb from overheating and burning out. In this regard, the Z4X really achieves a smooth and clean collection and release.

3. Acoustic noise test ：

People have been concerned about the problem of projector noise because the projector has always been noisy; In this experience, the author also conducted a sound noise test on the Jimi Z4X. The noise displayed on the sound noise measurement APP on Meizu MX4pro mobile phone is equivalent to decibels of whispering (the room is not absolutely quiet), which indicates that the small sound does not affect the viewing or conference display. In fact, it is not necessary to test, but you can also detect that the noise of this machine is very small after listening carefully.

4. Color test ： Official color parameters of Jimi Z4X

The following figure shows the color map projection live shot: the overall picture is ideal (the live shot effect is lower than the actual effect)

Color is one of the more important indicators. According to the above official data, and in the actual test, it can really be described as amazing and bright. Through the 48-90w power supply power range drive circuit and projection lamp, the dual light path optical engine can be maximized. According to different tasks (differences between ordinary movies and 3D movies) To achieve different power makes the color brightness uniformity very high; While I was measuring lumens with my mobile phone app, I got a "test environment is not within the acceptable range" error (after checking, I found that this mobile phone English app app was used to measure the light brightness within 175lm, but the time was too short to get a professional photometer, which was a pity). However, since I have used some projectors, I probably know about the lumen brightness. Generally, the brightness of the projectors measured by myself will be about 10% lower than the official data, because different results of the test environment and the test instruments are also different, (insiders said that when the brightness reaches 80% of the official data, it is qualified).

Here are some large pictures being projected and played. You can shoot them without any modification. You will be satisfied with the clarity and brightness of the pictures!

5. 3D performance test ： Unique 3D special effect enhancement technology -- starring Tom Cruise in Tomorrow's Edge

Unfortunately, we didn't have time to configure a shutter type 3D glasses, so we had to use ordinary 3D glasses for testing.

First of all, Jimi has specially produced special 3D shutter type 3D glasses for its own products. It is said that with the unique 3D special effect image quality enhancement effect of Jimi Z4X, the three-dimensional image is absolutely shocking. But I can still see a better effect with ordinary 3D glasses (the camera shooting effect is worse than the actual viewing effect). A feeling of 3D cinema creates a whole body, and I'm really happy!!!

6. Features of remote control: To insert a sentence here, the "remote control" plays an important role in the above 4-5 colors and 3D features.

I want to talk about the remote control separately. It has a very interesting electric zoom function. Usually, projectors focus manually on the side or below of the machine, which is troublesome, while the Jimi Z4X is electric focusing, intelligent and convenient. The clarity, resolution speed and the best picture display effect are very powerful, The remote controller can also carry out the trapezoidal surface correction interval with a vertical angle of ± 40 degrees, and the small remote controller has great effect.  

7. Music test ： The specific parameters have been indicated in the figure, and what the author wants to say is the controllability and sound resolution:

Let's start with controllability: after identifying and converting with high accuracy and 200 times per second sampling rate, the final result is that you are above the film Switch songs with a gentle wave , or fingers Draw a circle clockwise or counterclockwise to adjust the volume No need to slide the optical cover Tap the LOG position in the middle for 3 seconds to start Baidu Music , gesture control is unprecedented in projector products, so it is absolutely cool!

About the sound quality: the customized speakers of the dual channel Harman Carton, which is tuned by Alan Michel, its chief engineer, and cooperated with the ultra-low distortion digital power amplifier of Texas Instruments, are naturally excellent in terms of the analytical power of the sound quality and low-frequency expression. After my own test, the effect of the mid and high tones is particularly shocking. When playing the bass, I feel that the machine has a vibrating effect, It's not as powerful as professional subwoofer, but it's also very good. In addition, the sound of the Z4X has a 3D surround effect. Watching movies is very powerful. Harman Carton deserves its reputation.
In addition, there is a 3.5mm headphone output socket on the back of the machine, which supports coaxial 5.1 channel output. If you have an excellent 5.1 surround sound system in your home, you can enjoy more comfortable music experience as long as you are equipped with an audio cable (3.5mm headphone plug to RCA audio plug).

8. Test tool display ： 

Test experience tools include: Meizu MX4pro (sound noise measurement APP+brightness measurement APP), Soni α 100 SLR (also a Nikon D7200), infrared temperature gun, 3D polarized glasses, electronic city, tripod, and 2.4m projection screen

Let's talk about the machine weight of Jimi Z4X: 1.179kg. That is more than 2 kg. The portability is very good.

9. Conclusion of performance test ：
       Combined with the test of color and sound, we got very satisfactory answers. The picture is similar to the color level of the film master tape and high-quality sound 3D surround. We can enjoy the effect of cinema level digital projector whether it is the sound and picture display at work or at home.
       A series of test experiences can't help but surprise people. Like the official expression, "sound and picture are beyond imagination", this experience is more like an independent private cinema, giving you a wholehearted shock experience!

Pleasant experience:

In this article, we mainly look at the life style brought to us by the GMUI intelligent system:

1. Home page:

Take a look at the human-computer interaction brought to us by the GMUI intelligent system (based on the in-depth development of Android system). The homepage of the system is designed into four major categories of mainstream modularity similar to TV box: film and television, music, games, and applications.

The film and television is from the film and television resources of Mango TV, which is very popular for the parent-child education. The two-year-old daughter can learn children's songs and dances with a good touch.

Music comes from massive Baidu music, which is also my most commonly used resource download source.

Game: When it comes to the game, more people are concerned about whether Jimi Z4X can play. Don't worry! It's not only fun to play, but also super cool. Some games can be played through the remote control. The Jimi Z4X also supports XBOX, PS and other peripheral game consoles. I guess that's a great feeling!

Application is one of my favorite items: especially office software and some peripheral applications. I like office software applications because the projection form word no longer needs to be connected to the computer. It can play file documents directly, which is easier to operate.

For the first time, the GMUI intelligent system will have humanized guidance, including: remote control and machine pairing, 3D gesture control test, electric focusing method, configuration of wireless wifi, etc. There is a page of simple instructions for starting up and remote control in the packaging box, and there is an electronic manual in the system, step by step to bring your understanding of it and use it in learning.

2. Setting and management ： On the system home page, press right through the remote control to display the management configuration interface

The area on the right is the application icon area. All applications installed in the application category will be displayed here. The figure shows the system's own applications. The system settings include: wifi connection, Bluetooth, projection, general, system upgrade and other interfaces. Because it is relatively simple and easy to understand, no large picture is attached.

The cursor is located in the remote cloud, which supports remote Thunderbolt download. This function brings good news to office workers. Remote download in the daytime, and you can directly enjoy 3D high-definition when you return home in the evening, just like a considerate housekeeper taking care of your arrogant temper.

3. Storage and connection ： The system home page displays the storage and connection interface by pressing left on the remote control

The interface display is the author's Kingston USB flash drive. The form, word and other office documents in it can be opened directly (it can be changed by connecting the keyboard and mouse). It is no longer necessary to connect to the computer. When the cursor is down, it is 16G storage (it is even better if a 2.5-inch hard disk is installed on the chassis. I just have a disk that I removed from the mobile hard disk. It's great to try it on).

Then there is the connection between HDMI and AV, which is the fundamental projection function. If you often have meetings or music parties, you can connect through wireless connection or high-definition port, which is much better than the VGA interface of ordinary projectors. It is not only high-definition, but also with sound. How tall it is!

4. Cell phone Jimi assistant ： This is great

The interaction between mobile phones and projectors is not mentioned at the beginning of this article, which is to be discussed here; The picture is the screenshot of the author's Jimi assistant on the Meizu MX4pro mobile phone. The Jimi Z4X supports Airplay/DLNA/Miracast multi screen interaction, mobile phone remote control, mobile phone projection, resource sharing, etc. More carefully, from the left picture, you can see that the functions of keyboard input, touchpad, focusing, etc. are complete, completely replacing the remote control, It brings good news to families and friends whose remote controls are easy to lose.

The way to install the Kimi assistant on the mobile phone: download the Kimi assistant APP by scanning the projected QR code, and install it on the mobile phone (or download it on the official website of Kimi). After opening the app, it will automatically search for the connection with the Kimi Z4X in the LAN. Congratulations, your mobile phone can control the Kimi Z4X, and you can also put pictures on the same screen to watch movies and play games.

5. About Mango TV and Baidu Music ：

In front of this article, there are often pictures and texts of Mango TV and Baidu Music, which is the result of the deep cooperation between Jimi, Mango TV and Baidu Music. The powerful and powerful have joined hands to share resources. Although the machine package comes with a 24 month Mango TV membership card, you can enjoy the Mango VIP service, and directly enjoy the super high effect of Mango TV in the giant screen HD.
6. Experience conclusion ： Now more and more intelligent devices are coming into the family and life, and the Jimi Z4X is also the best among them. It is an indispensable part of the new era of technology family that does not force, does not pretend, and integrates into life to improve the quality of life!

Appreciation of blockbusters:

The following is the author's personal photography of Jimi blockbusters, without any modification, please go to the photo paste for more blockbusters.

In addition, the author's experience and suggestions are also included below. Please don't go away!

Experience:

Through several days of experience, I have learned its superb skills. Simple design and powerful functions are the ideal state of all products. Obviously, Jimi Z4X has made great efforts in this regard. A good brand and product will inevitably go through the process of being immature and mature, while progress has never stopped. Here's how I feel after spending several days with Jimi Z4X:

• With regard to the chassis of the machine, after the whole machine is placed horizontally, the picture of placing is sometimes slightly non horizontal. Because there is no base adjustment similar to that of traditional projectors, the adjustment degree is limited (trapezoidal adjustment is not always effective here); Another point is that the installation of a mobile hard disk on the chassis will inevitably increase the heat of the machine. If the chassis foot can be adjusted a little farther, it will be very beneficial to the chassis cooling. Therefore, from my personal point of view, it is recommended to consider the beauty of the chassis while adding convenient retraction and retraction feet.

• For ladder calibration, it is convenient to adjust the vertical ladder through the remote control, but horizontal ladder adjustment cannot be carried out (that is, the left and right directions cannot be adjusted). This requires adjusting the machine from left to right, so that it can be placed at right angles to the wall or curtain, otherwise the two ends of the screen will be uneven.

• At present, the GMUI system has been optimized well, but small bugs occasionally appear in the use process, such as a few individual applications that prompt application crashes. I hope it can be handled in the later firmware optimization and upgrade.

• At present, the GMUI system does not support the installation of apk applications downloaded through channels other than the system, which makes the GMUI system with TV box functions more conservative.

• For a suggestion on the operation of the whole machine, add the head cover log to touch and shut down the machine. At present, it can be turned off in two ways: A. The remote control can be turned off (the interface can be turned off or light off, etc.), and then the slide cover can be closed. B. Directly close the lens slide cover. At this time, the machine will automatically enter the song playing state. You need to touch the top log to close the music (sometimes the touch will be recognized as the song cutting gesture), that is, you need to complete the total shutdown in two steps. However, we all know that remote control is a relatively easy thing to lose (especially when the Z4X is a home theater at home, Jimi also has an alternative solution, which is to replace the remote control with the mobile phone's Jimi assistant). When the remote control or mobile phone is not around, it becomes more troublesome to shut down. It is best to coordinate the operation of the optical phone and the music machine if it can be more convenient to operate, For example, when you touch the top log for a long time, a prompt similar to the remote control's power off option appears, or you can add functions such as pressing Start and Close on the indicator light.

• Will Jimi customize a projector travel bag for its own products (especially its Z4X)? The small bag specially equipped with the Z4X machine and the power remote control must be tall to use. I can't carry a large box around on business trips, nor can I put it in a laptop bag. At present, there is no bag specially equipped with such projections in the market (if there is any cost, it can be sold on the official website like shutter 3D glasses). This is a user's demand.

• In addition, there is also a nitpicking suggestion. The power transformer wire has no binding tape. I always find someone who is obsessive compulsive to twist the wire like iron wire. If only I could learn from the binding tape on the laptop power line. This can be easily achieved.
