·How long have you not watched TV? I think as long as Saonian and Gu Niang are about the same age as the spoon, most of them will say that they haven't watched TV for a long time. Once upon a time, they seemed to watch live TV in the impression of the spoon. But now, with the development of live channels of major video websites, live ball games, live conferences, live concerts, live TV programs, and live galas. It seems that what TV can do has been completely replaced by Internet TV. However, the size of the computer's display is limited. Even the new generation of network TV is close to the limit of 60 inches for ordinary families. In addition to users who are very concerned about hardware, the TV size of most families is still around 50 inches. Look at the equipment price. Some large screen imported LCD TVs are not acceptable to ordinary families. Even if they choose relatively cheap domestic brands, the price of large screens will not be lower than thousands. What if the 300 inch display is less than 3000? Don't think the spoon is joking. It's not 300 inches, but 72 inches. As for the effect, what you hear is false, what you see is true.

·Chengdu Gemi Technology Co., Ltd. was founded in November 2013. The company is mainly composed of young and energetic young generation after 80s and 90s, so we can imagine that their products must be at the forefront of the times. In fact, the spoon first knew about Jimi in July and August this year, from the first time it heard about it to the later time. We have to admit that Jimi has done a beautiful marketing. All kinds of evaluations and unpacking have been painted on the screen of all major platforms almost overnight. Some people may say that it is all a means of business promotion to find various writers to advertise. At first, I had the same idea, but many doubts would be dispelled after I really experienced the product. In fact, marketing a good product is only an essential means, but if the product is good only by boasting, the leather will be broken sooner or later. In fact, if you are careful, you will find that there are few people who are not good at spraying products, even if they are full of soft articles and unpacking, Unused ones are not qualified to spray, and used ones have no reason to spray. For a product with strong performance, high quality audio and strong support from software, the price is only a mid to high-end mobile phone product. Maybe it is not perfect enough, but it is indeed an industry leader.

▲ 580 lumen can be said to be an absolute leader in household portable projectors. In fact, the success of a projection device basically determines half of the success or failure. The high lumen brings serious heat, noise and other problems that cannot be avoided. How about Jimi in these aspects?

▲ Here, we can see that the Jimi system is actually an Android system like our ordinary smart phones, with four cores of 1.5GHz, 2GB of storage, and 16GB of storage built in, among other things, the mobile phone with this configuration is also about 1000 yuan, let alone a projection.

▲ A rich interface is an essential configuration. The more room for users to make personalized choices with any successful hardware device, the more pleasing it will be to users.

▲ The noise is less than 30dB, and the power consumption is 48-90W. I'm afraid that these two values will come out. In fact, some questions will be answered very well. It is doomed that there will not be too much unsatisfactory in terms of temperature and noise. However, we will continue to look at the actual experience.

Note: First of all, it should be emphasized that the evaluation principle of the spoon is "not blindly black, not blindly blowing". Everyone is a separate individual existence, so if you want to cover everything, I can only say that it is difficult for everyone to adjust. For the good and bad of a product, the actual experience takes priority. The spoon is not a professional evaluator, so if there are any questions in the description below, please point out that the spoon is all modestly learned and accepted.

▲ The simple and generous outer package can hardly see any superfluous labels and patterns, and the attached tripod bracket is attached. It is convenient to associate the Z4X with the tripod.

▲ It can be seen from the simple package of a foot rest that the design is fine. The front of the box is a square, but not a cube. The logo of Jimi and the logo of Mankaton are printed around.

▲ When the box is opened, the Z4X comes into view. The package is very secure. There is a thick sponge around the host, and even a layer of sponge on the top of the box cover. Accessories are as described in the above product parameters. A set of power supply, a remote control, a host, a mango membership card, and screws and other small pieces will not be described in detail.

▲ The most conspicuous part is the black imitation plastic tray design on the top, and the red decoration is even more icing on the cake? What on earth is this? Please look down.

▲ If you look at the Z4X and then the outer packaging, what do you think? No design comes at random. In fact, the seemingly simple outer package has already told you the shape of the products inside, hasn't it?!

▲ Upper black plastic disc, lower black plastic disc. The corresponding design is very good. The glue used in the bottom several anti slip pads is very good, and the anti slip effect is excellent. Note that the three round anti slip pads can be removed.

▲ Lens cover can be opened and closed manually, just like this? Of course not.

▲ This series of jacks on the back will not be described one by one for the time being, and the details will continue to look down.

▲ The minimalist design of black, white and red does not add any individual color. Can you say that it is not a successful industrial design?

▲ The remote control is not big, but it is enough to tactful Z4X. Some things really do not need to be too complex, simple and easy to use is enough. As a 2.4G remote control, the highlight is that you can control the machine without pressing it. For example, if I want to control the machine in the living room, it is effective!

▲ You spent more than 2000 yuan to buy equipment, and then gave you a mango TV membership card of 720 yuan for two years. Although some programs still need to pay for a single on-demand broadcast, it is rather dull. But most resources are free, which is also a kind of welfare.

▲ In the end, the power supply should also show a mirror. To be honest, it is not the main character, but there is also a test for it, and the result is quite surprising.

▲ Harman Carton, Mango TV and Baidu Music are all partners of Jimi. The old saying of "one hero, three gangs" is not just a random saying. A good jiyou will live forever. This is the end of unpacking. What I want to say is that I didn't give 3D glasses. It's very uncomfortable! If you don't give it to me, you will not test 3D. If you don't test 3D, you will not test 3D. If you don't test 3D, you will not test 3D. Say important things three times.

▲ The overall shell material of Z4X is frosted hard plastic. It feels good, but it is easy to get dirty. In addition, the spoon itself is white, which is unacceptable to people with obsessive-compulsive disorder. After using it for a few days, I feel that it is turning yellow, and I don't know when it will really turn into shit yellow.

▲ The lens cover is mentioned when unpacking. It seems to be a dust cover, but it is not. It also takes into account the switching function. If the lens cover is closed and you open the Z4X, the Z4X is not fully powered on at this time, but you can enter the music listening mode and enjoy the listening enjoyment brought by Harman Carton. Normally, if you have connected to the network, the machine will play online songs through Baidu Music. Of course, if you have songs stored locally, it can also play local songs. When you open the lens cover, the light machine will start to work. If the power is on, you can quickly turn on the projector by directly moving the lens cover. However, what I want to say here is that the lens cover and the card slot are not very comfortable to use.

▲ It is needless to say that this figure is to show the relationship with Harman Carton. It seems that the brand effect still exists, and identity and status are often reflected in a logo. These irregular holes are actually the sound holes of loudspeakers, which are avoided by people with dense phobia.

▲ After looking at the front, let's look at the back. There are a variety of external jacks, which can be seen enough at one time. There are two AV video inputs and HDMI inputs alone. Although the Z4X itself supports wireless networks, the direct plug network access can better ensure your network speed and improve the quality of experience. The USB 3.0 2.0 access allows you to easily read the data of external storage devices. In addition, many peripherals also need to use USB adapters to complete docking. Here we also mentioned in detail later. Maybe few people will use this 3.5 headphone jack to really plug in headphones, but it's still good to have a stereo or something. But then again, why do we need to connect it externally when we have Harman Carton? Of course, if your external connection is more powerful, just plug in!

▲ The other half is the rear hot air outlet. All the hot air of the Z4X is discharged from the machine through this outlet during its operation. We can imagine its importance. Let me show you a detail. It is estimated that few people know that Z4X has designed so many metal fins here, and the details often determine the final quality of the product.

▲ The lens spoon is not a professional, so I don't want to make too many comments. I only know that 580 lumens make this "eye" strong enough to make viewing clearer.

▲ I still remember the little red bar before. In fact, it is an LED power indicator. I have to admit that under such color matching, when the red light is on, the beauty is suffocating.

▲ The black glue tray on the top is actually not that simple. The LOGO part of the middle pole meter is a power switch button. You can switch on and off the Z4X by long pressing. At the same time, when simply playing music, you can switch songs by waving the gesture above the black plastic disc, and the measured effect of the spoon is very good.

▲ In fact, the spoon has not had an intuitive feeling for a long time at the beginning. I believe that many kids are the same as me. It doesn't matter. Here's a comparison chart. Compared with cameras, you can get a general idea.

▲ On the other hand, looking at the bottom, another unique design of Z4X is that it can have a built-in hard disk. The significance of this function can hardly be expressed in words. Here, the spoon is only an ordinary notebook hard disk, and the official recommendation is SSD hard disk, because Harman Carton is so powerful that ordinary applicants are more sensitive to vibration and easy to damage. SSD hard disks are also more reliable when used in combination with speed. Z4X supports 4K video playback, but if you expect online viewing or external storage devices, it is certainly not as convenient as downloading directly to the built-in hard disk. In addition, Z4X supports remote Thunderbolt downloading, that is, you can download your favorite movies to Z4X remotely through remote Thunderbolt at work. What a huge function, can you do without this hard disk storage.

▲ This is a tripod bracket, which can also be understood as a lifting bracket. In short, it is used to help you fix the Z4X where you want it to be fixed. The three screws are directly stored on the bracket by ingenious design, so it is not easy to lose the thoughtful design. And it's just a bracket, and the workmanship is impeccable.

▲ The effect after installation is like this, so you can put the Z4X on the tripod or hoist it on the roof after assembly. It's very convenient and simple.

▲ Let's look at a small detail design. The spoon always thinks that an excellent product and an excellent design are always reflected in details. If you don't understand it, it doesn't matter. If you understand, what do you think?!

·It has to be said that how much hardware can match and interact with other hardware is absolutely an important standard to reflect the practicality of a product. We can see so many interfaces, but we have to experience some things before we know what is going on.

▲ Polar night remote control, the fighter in the remote control. It was originally used with the Polar Night console. Of course, its ability is far more than that of the Polar Night console. I can tell you very responsibly that this awesome remote control completely matches the polar meter Z4X, and it is also easy to use. Just plug the adapter of the Polar Night remote control into the USB interface behind the Z4X, After waiting for about 3 minutes, you can completely replace the original remote control with the polar night remote control. Here are some highlights;

1. Full keyboard input. There is a full keyboard input operation area on the back of the polar night remote control. The longest case encountered in using the Z4X is text or alphanumeric input. With the original remote control, you can only press. With the original remote control of Polar Night Instant.

2. Voice search, the function spoon is still experiencing, but it's awesome to just try it out. How can it continue to look forward.

3. The polar night remote control has a built-in gyroscope, so you can select the corresponding options on the page by shaking the remote control in cursor mode. Are you still demonstrating PPT with laser light? You have been out for a long time. With the combination of Z4X and midnight remote control, it is the best choice for those who want to have a compelling product demonstration or training course.

▲ The Z4X has the Bluetooth connection function, so you can directly connect your Bluetooth game handle to the Z4X. I don't need to say anything about the connection. After the spoon test, basically all the games in the Z4X can perfectly fit the Bluetooth handle. In addition, if you feel that the built-in games are not good enough, you can connect devices such as TV box game boxes through HDMI interface. For example, here the spoon is used to test the connection of game boxes with Myriad Little Bora, which perfectly fits the use process. With a handle, a giant screen game console is born. Of course, you can also connect your game console XBOX, PS, etc.

▲ Fear of disturbing your family when watching movies at night? It doesn't matter if the Bluetooth headset is waiting. All kinds of USB flash disk removable hard disk storage devices can be plugged in.

▲ Speaking of this, many people must be curious about how such a projection heats up? It is true that heating has always been a hard injury of projection. Let's compare and see what the heat of Z4X is after 6 hours of work. The temperature rises by more than 10 degrees. Of course, since the spoon is not professional and has no professional equipment, the test results can only be said to be for reference, but the spoon can be said responsibly that it is not hot to touch with your hand.

▲ It is here that the spoon was shocked by the power supply mentioned earlier. The machine is really not hot. But the good guy's power supply heats up nearly 20 degrees, and I'm really worried about the service life of this power supply. I don't know whether the officials will notice this and provide solutions in the future.

▲ Here is a small test for the 30dB mentioned by the official. Of course, the sentence is still limited by conditions, and the test results can only be used as a reference. If you want to say that the projector is completely silent, it is bragging. In fact, 30dB is a bit exaggerated. The measured results are similar to my estimates. About 60dB. Let's popularize about decibels.

"Decibel is the unit of sound pressure level, recorded as d B. It is used to indicate the size of sound. One decibel is about the sound that people can just feel. The suitable living environment should not exceed 45 decibels, and should not be less than 15 decibels." According to the hearing of ordinary people:

0-20 decibels is very quiet and can hardly be felt

20-40 decibels quiet, like whispering

40-60 dB ordinary indoor conversation

60-70 decibels noisy and nerve damaging.

70-90 decibels is noisy and nerve cells are damaged.

The noise increased from 90 to 100 decibels, and the hearing was impaired.

100-120 decibels is unbearable, and temporary deafness occurs after one minute.

▲ In fact, except for the bracket and power supply mentioned above, the accessories are really nothing? Just this card. warranty card? It's still this card. In fact, don't think it is simple, because there is no need to teach you anything. You just need to learn the operation on the card. Why? Look down.

▲ I almost forgot that the remote control is a button battery, and I gave a free one to Jimi in the package.

▲ Considering that the spoon is not a professional machine disassembler, the machine disassembler here is just a taste. Please don't spray it. The biggest feeling after opening the shell is that the internal structure is compact and orderly, making use of almost all available space. Finally, I understand why the size of Z4X can be reduced to this bottom. Every part is where it should be. There is only one piece. I didn't see any components with poor workmanship.

▲ It can be seen that all the solder joints are beautiful and clean. Gently pull out the connecting wire and I will remove the top shell.

▲ Remember the red stripe on the black glue plate? The close-up here is the internal LED light. It can also be seen that the surrounding electrical components are arranged neatly and the solder joints are clean.

▲ Come and see what the Harman Carton is like. To be honest, the effect of this Harman Carton can only be used in a standard way, and it does not achieve a very amazing effect. But as a part of a projector, I think this level is enough. But the sound quality is really ordinary.

▲ In addition to the heat dissipation metal plate I introduced earlier, there are also many small parts that have been designed with the overall situation in mind. It is conceivable that such product design has experienced many improvements at the beginning, and now has the results.

▲ Here is the bottom of the hard disk compartment, and we can clearly see the existence of the cooling fan. The Z4X can achieve good temperature control, not just talk about it, but many designs are implemented. To have the best user experience.

·The Z4X uses a Qualcomm 4-core 1.5G CPU, Mali-450MP4 GPU, 2GB DDR3 memory, and built-in 16G eMMC high-speed flash memory. The system is GMUI developed based on Android 4.3, and the GPU is Mali ™- 450MP4, its performance is 104Mb triangle/second, 3800Mb/second pixel fill rate. The resolution of the official data Z4X is 1280 × 800. 4K is display compatible, and resolution is different. In the actual measurement process, basically ordinary format videos include some 2K4K videos. There is no problem with Blu ray. Only a few abnormal bit rate videos cannot be played. But I think ordinary users certainly have no abnormal demand. As for video playing and system score running, I will introduce them in detail later. Let's look at the system operation first.

▲ Enter the main interface, mainly including:

Film and television --- integration of various resources.

Music --- provided by Baidu Music.

Games - in fact, some Android games. As long as you like, you can download the copy you like to install, but the compatibility is hard to say.

Application --- It is also an Android application. Most Android software can also be copied and installed.

▲ You can log in to your Mango TV account at the position in the circle. Many functions can only be realized after login.

▲ At this time, we should say again that the importance of the polar night remote control is not a worry with polar night input.

▲ After logging in, the upper right corner is no longer unlisted. At the same time, you can click the wireless network logo in the upper right corner to quickly enter the wireless network setting page.

▲ There is no need to repeat the connection process. It is better to mention the Polar Night and Polar Night again. Input is not troublesome. Ha ha~

▲ Here we can see that when you move the cursor to the bottom, you can quickly add a shortcut application bar for your future use.

▲ Actually speaking of humanized design, you can quickly call up the settings of each interface by clicking the left button on the main page. You don't need to do too much more operation. At the same time, you can quickly find the mobile storage device you access outside.

▲ The system settings are also simple and clear. The main network, Bluetooth and projection settings are here, as are some general settings.

▲ There are some basic settings in the general settings. I saw someone on the Internet who said that he could not turn off the music. I can only say that he should not patronize the movie settings but also carefully browse them. Whether to play built-in music or network music is also set here. It is not seen here that users are allowed to choose their own images as the theme, which may be supported in the future~

▲ In the image setting, we can set the display effect that is more suitable for our own viewing according to our own habits and preferences, similar to the computer display settings.

▲ There is nothing much to say about Bluetooth settings. Like most mobile phone Bluetooth connection settings, search first and then bind.

▲ In the projection settings, there are some detailed settings for the Z4X, forward and reverse projection settings, trapezoidal correction, which are very practical, but unfortunately, the Z4X does not support left and right horizontal correction, which is more troublesome in the use process, because your machine must be on the central axis, sometimes affecting the viewing.

▲ When you log in to the account, you can realize some functions of backup and download. Personally, the backup function is very practical.

▲ Rich film and television resources, especially variety shows, because Mango TV's "Happy Camp" and "Day by Day Upward" are the main features of Hunan TV Station. According to the official introduction, there are nearly 3000 films, more than 100000 episodes of TV series, and a total of 300000 hours of film and television content, and they are constantly updated in real time. All the content has been authorized by the legal edition. Don't forget that we have free members who can enjoy these for two years.

▲ What song do you want to listen to? Search! Baidu Music is still rich in resources. All kinds of music lists and rankings are vivid. Local music can also be easily opened.

▲ All kinds of games and applications are built in two windows. If you think the resources are not rich enough, you can also directly download APP copies to install them.

▲ Mango Internet TV on the main page is the core part of Jimi Z4X. After clicking it, we can really see how massive resources are. It basically covers all the resources you can imagine and want to see.

▲ Trembling boy, I feel that I can't spend my whole life watching these. But after all, the copyright issue has been mentioned on the table, so resources may not be everything you want to see, but don't forget that Z4X is an Android system! You can download and install any APP, such as Tudou, Youku, LeTV, iQiyi, Tencent, 360 AV, and then you will understand~

▲ Finally, let's take a look at the service, which can be said to be extremely considerate. Let's not talk about members. We can find ways to solve common problems and other product problems. Do you think that's all that's sweet? Keep looking down.

▲ Remember that the spoon mentioned a simple question about the instruction manual at the beginning. In fact, it is enough for you to learn the basic operation on that card, because all your operation problems can be solved in the electronic instruction manual of Z4X. How detailed? Keep looking down!

▲ The built-in instructions almost cover all the problems related to operation, and are illustrated with pictures and texts. After reading these books, it is almost impossible to find someone who can't use them, and you may not find the paper manual for a long time. The electronic manual can be easily consulted by anyone at any time and anywhere as long as you open the machine.

▲ Finally, the mobile phone APP Jimi assistant is also very powerful, so I will not mention that I can remotely control the Z4X. It is very convenient to share mobile resources on the same screen. In addition, you can uninstall the software already installed in Z4X in Jimi Assistant, without having to search the system again.

▲ The effect of screen projection is absolutely first-class, but it is still a little low between 2.4 of the wireless network connection, so a little bit stuck, or the spoon phone is not good, in short, the function is OK, and the experience is a little bit small.

▲ These two pictures are the effects of the photos on the projection mobile phone. It is no longer a problem to show others the beautiful pictures or videos on your mobile phone.

▲ In addition, there is a voice function in the mobile assistant. Try talking. The system is really funny. Tell me what you want to do. Tell me what you want to see in the movie. What will happen after that? Have a guess?! So far, the brief introduction of the system and APP has come to an end. In fact, there are still many details that have not been mentioned, but it is really hard to write down.

·Having said so much, we are finally going to enter the main link. No matter how much hype, how beautiful the pictures are, how realistic they are, right? Many people must think so when they look at them! Because the shooting is affected by the environment and cannot reflect the effect on the screen most realistically, but every shot of the spoon is taken from dozens of photos that are closest to my visual effect. The shooting machine is an ordinary 700D set, and no more powerful machine is used. There is a screen, a 72 inch white plastic screen, and the shooting time is in a dark room at night. The curtain effect is the final effect. Only part of it has been cut, not later.

▲ The reason for choosing this picture is that fog is a relatively difficult environment to show. We can see that besides a little lack of brightness, plant details and fog are all presented~

▲ The contrast between green and blue in this picture is very strong, and the color saturation can be seen at a glance. In addition to the slight lack of brightness, other performances are also good.

▲ In this picture, we can see that the blue sky and red maple leaves are slightly discolored, including the projection of whose side. A large part of the reason is the camera shooting. The actual viewing effect is not so serious.

▲ This night scene is the most perfect for color restoration, and the detail expression is also good, especially for the performance of dark places.

▲ It is still an old problem that the color changes a little and the brightness is a little insufficient, but the actual viewing effect is absolutely good. Hair and eyelashes are clearly visible, and eyes are bright and clear.

▲ The problem is the same as that in the previous picture. After all, it is the projection effect. We still need to be more inclusive, but we believe that the actual viewing effect of the spoon is absolutely shocking.

▲ After passing the above test of some samples and professional test pictures, the spoon makes a summary. The dark part performance is normal, and some bright parts lack expressiveness, sometimes appear white or color bias. The detail performance is good, and pictures with high color saturation occasionally appear color bias. The image level and contrast expressiveness are sufficient, especially in contrast. However, the white lime wall is definitely not as good as my white plastic background, but it must be more deficient than the better fiberglass curtain. If you have the conditions to use it, I suggest you reach the goal in one step. The glass fiber screen has a more obvious brightening effect. It can also be seen that there are many kinds of screens in front. Other performances are good, but the brightness is not good.

(Let's take a look at the 4K video playing.)

Video stream information+encoding format: AVC+video code rate: 88966 kbps+video frame rate: 29 fps+resolution: 3840 x 2160+Display ratio: 1.778 Audio stream information+Encoding format: A_AAC/MPEG4/LC+audio code rate: 317 kbps+channels: 2 channels+sampling number: 48000 Hz+audio bits: 0 bits

▲ Please forgive me for my limited photography level. I really can't shoot the actual color and brightness better, but the spoon responsibly said that the performance of the 4K video is really amazing. After all, it has been put into the size of 72 inches. Compared with the LCD TV, it may not be so exquisite, but the viewing effect will never disappoint you.

▲ Since it is an Android system, why not run a score? There is no difference between the measured hardware configuration of the rabbit and the official report, and all the hardware coefficients can be seen. As for the score of 21669, some mobile phones may not find this score, right?! So the smoothness of the Z4X system is very good. The best thing is that most software can be installed!

▲ These two pictures are two games downloaded and installed from the Z4X internal application store. Of course, there are many different types of games for you to choose from. They are very rich and entertaining. The spoon mentioned the connection between the digital set-top box and the game box, and the following is the connection interface of Xiao Bao.

▲ If the system's own applications and games do not meet the requirements of using TV boxes and game boxes to expand resource content and game content, it can also be regarded as a supplementary means. In the actual test, there is no compatibility problem in normal use.

·In fact, there is still a lot to be supplemented and improved, but in order to read fluently, it is no longer wordy. The experience of the past few days can not be overemphasized. My father and mother have abandoned the TV, and they will watch it for several hours every night. During the promotion of Jimi, the product was defined as "super large screen TV without screen", Its ambition to occupy the living room is also obvious. In terms of playback effect, audio quality and other aspects, it is not too hard to say that Z4X is the top in the industry. There are also some slots. Personally, I don't like the case that is easy to show old. The lens cover is not smooth, and the color display is too bright, which is easy to become white and distorted. Only trapezoidal proofreading, not left and right. Many system applications have problems with game compatibility. Some apps copy mobile phones without optimizing the display screen proportion. You can add SD card slot, TF card slot, and it is more convenient to read the camera memory card directly. There is no saying that a product is perfect or not perfect, only the intention. The spoon thinks that the Jimi Z4X is definitely a product with enough thought. You can't experience it without actually experiencing it. When you really experience it, you will exclaim that the giant screen is so cool!

Finally, thank you for taking the time to watch the "bullshit" spoon, and welcome you to have the time to keep watching the spoon. The "bullshit" microblog of various "bullshit" spoons is: . Technology changes life and nonsense changes the world.
