Speaking Z4X No screen super TV, students should not be unfamiliar. After all, back in two thousand and fifteen year six month thirty On January 1, Jimi released its flagship product at that time. Although its official name was no screen TV, it was actually an intelligent projection product. Several friends also talked to me about its high picture quality and high sound quality. Today, we are lucky to be able to play at Lei Feng's website. Whether it is as recommended by our friends or not, let's explore the appearance, process, performance and other aspects together.

"Packaging design, surrounded by black and white, is consistent with the product design style"

At present, more and more manufacturers begin to attach importance to the packaging box that seems to be solely responsible for a one-time mission. After all, product packaging is the first display window and can also output its brand value.

Polar meter Z4X The packaging box of is designed with white and black as the main tone. The box surface is simple and clean, without redundant and cumbersome content, which is consistent with the color matching design of the product itself. The protection is also in place. For example, the upper part of the box is pasted with a layer of protective sponge, the middle of the box is also covered with sponge for surrounding protection, and the accessories area at the bottom is classified by different boxes. The upper, middle and lower protection protects the host inside, to a certain extent Z4X Long distance transportation safety.

Z4X The product manual of "" continues to be simple. From the fuselage protective sticker and partition card, you can generally understand the fuselage information, operating instructions, warranty regulations, etc. If you want to know everything in detail, you'd better check the website of Jimi. Other accessories, including power supply, remote control, adapter plate, hard disk fixing screw, mango VIP Membership cards and some accessories will be introduced later.

"Appearance and appearance, modern world of black and white color contrast, love rubbing and sanding touch"

Polar meter Z4X The recognition degree on the appearance is good, which avoids the stereotype boredom of traditional modeling and the difficulty of component layout caused by personalized modeling. On the basis of traditional modeling, Jimi is smart enough to add a touch sensitive area similar to a turntable, creating personalized functions and a personalized appearance.

The white square fuselage and the black turntable control area just echo the patriarch's "round sky and place" cognitive theory. The contrast between white and black, the interlacing use of straight lines and arcs, also conform to the theory of yin and yang balance. Therefore, Z4X that 196*196*50mm Although it is only a little larger than the palm, it still creates a stable, safe, balanced and soft visual sense.

The white body is made of engineering plastic, but after sanding treatment, the texture is greatly improved. It reminds me of a kind of sanded ceramic tile that I used at home when I was a child, and I also like the delicate and blocking feeling of rubbing. However, this kind of frosted white has poor protection ability against dirt and scratches, so we should take good care of it.

The black touch area is different from the white body. This part not only looks like a turntable, but also has similar texture and highlights on the surface. Singing sounds will come out of it in a trance.

Polar meter Z4X The remote control of is very small, covering basic commonly used functions. The feedback feel of the keys is also good, but there is no remote sensing function. It is a little inconvenient to keep pressing up, down, left and right on some operations such as entering passwords.

"Detailed design, with careful consideration, also has some necessary points"

The first approved detail design is Kimi Z4X The designed lens protection door can open and close the "window of God" with a simple physical push and pull action. The lens can be adequately protected during daily carrying and placing.

The second recognized detail design is the configuration of USB 3.0 Interface. On the physical interface two individual HDMI Interface, two individual USB Interface, one individual AV ， one individual LAN The interface can also meet general needs. In fact, I only need WIFI That's enough. however, USB 3.0 The interface is still necessary. Load high-quality movies on the mobile hard disk USB3.0 The speed can be guaranteed. Besides, that 3.5mm Headphone connector, also supports SPDIF Coaxial output, however, the tail has no dedicated conversion wire verification.

The third recognized detail design is the built-in two point five Remove the three screws on the base of the "" solid state hard disk cage, and unscrew them according to the arrow on the back cover. The official warning is that the mechanical hard disk cannot be put into it, which will affect the hard disk due to the vibration of the horn. With the built-in solid state disk, the movie resources can be placed inside for convenient Z4X Take it out for use. Advanced users can also use Thunderbolt in the system to download movies remotely, and Z4X It supports the protection of turning off the optical device when downloading. In fact, the tail also thinks that the above is not true. I agree with a classmate who said that the best use here is to hide private money. My wife must not find it.

Introduced the identification points, as well as the slot points. See for the first time Z4X I didn't find the threaded hole connecting the tripod when I was at the back of the table. Do I need a high table for projection? It was only when I saw the lifting adapter plate that I understood, Z4X Instead of putting the tripod threaded hole on the body, it was put on the adapter plate, which finally solved the tripod problem. However, take a step back and think that the tripod is inconvenient after all. What if you really want to put it on the table? Is the placement not horizontal? The travel of the three screws at the bottom is too short to adjust the level. The trapezoid correction of the system only supports vertical correction, not horizontal correction. It seems that in order to obtain the best projection effect, it is recommended to use a tripod in addition to lifting, which is convenient for height adjustment and horizontal angle adjustment.

System UI , simple and content, scalability but compression, stability needs to be enhanced "

Polar meter Z4X Of UI Android based four point three Deep customization development has been carried out, but Android has been removed from all interfaces and settings. Because the bottom layer is the Android system, you can actually understand that this is a TV box with its own projection screen, and its functions are similar to those of the current box. Z4X The interface classification of is simple and clear, and the main interface is film and television, music, games and applications. The pictures in this part are mainly based on gif Dynamic diagram display.

The main purpose of using projection is film and television application. Polar meter Z4X And mango TV Strategic cooperation has been carried out, with random bonus twenty-four Mango for months VIP Service, you can watch members' exclusive videos without waiting for advertisements. What should we do after two years? If you want to use it, I can tell you secretly that a certain treasure sells for several yuan a month. In fact, I'm still used to watching movies with TV cats VST Total polymerization, etc APP However, the management of XXX is too strict and useless.

Music, this is Jimmy Z4X As one of the selling points of UI Music resources on the main interface also occupy a large area. This part of Jimi chose to cooperate with Baidu Music, and the selection of music is also very convenient. The classification of new songs, lists, radio stations or local music is very clear, and it is also good to listen to music quietly instead of watching movies.

In the game part, let the tail suddenly return to the childhood. Boxing King, Dinosaur Quick Strike, Small Tank, Metal Warhead, etc. are classic games. If there is a handle, it is also very nice to relive the happy time with the big screen.

When I saw the app, I even had a crying heart. The control was too strict. Only five or six apps, such as Ask Doctor and Buka Comics, could be downloaded. There was no browser. The scalability was almost blocked, and the downloads were all U On disc VST etc. APP , can't even see it in the resource manager. I heard that this problem occurred after the latest system upgrade. I hope there will be a solution in the future. In addition, after upgrading the system, there were several program error prompts, and it is recommended to optimize it.

The setting interface is divided into six parts: network settings, Bluetooth peripherals, projection settings, general, user, and about. It is simple and intuitive, fully explained, easy to use, and has no threshold. also, Z4X An electronic instruction manual is also provided to provide detailed graphic descriptions of various settings and operations for Xiaobai users.

Polar meter Z4X It also supports the use of Kimi assistant APP , using the mobile phone to control the projection, and more importantly, you can press one button on the same screen, and push pictures and videos on the mobile phone to the projection screen, which is most convenient and useful for sharing some happy moments. stay APP It is suggested to develop the game adaptation function. Although gravity sensing is supported, the keyboard development is not enough. It is suggested to choose different keyboard modes according to different game types, such as the simulation operation of racing and shooting.

"The combination of video and audio, dual light path optical engine, Manhattan sound system, and impressive effect"

To talk about the effect of video and audio, let's focus first. If you are dizzy, you can't see anything. Polar meter Z4X The electric focusing is adopted, and the manual focusing is carried out through the two buttons of the remote control. The official data is that the accuracy can reach zero point zero six And in the options in the settings, it is given that the focusing image can be accurately focused. The accuracy of the whole area is good, as seen from the effect after focusing. However, the tail is a bit obsessive-compulsive. During focusing, you always have to go back and forth several times to believe your glasses. The pictures in this part are all live pictures. There is no later stage, only the frame is cut.

In terms of hardware, Z4X With four nucleus 1.5GHz Processors 2G DDR3 Transportation and storage, 1080P 、 2K 、 4K There is no pressure in video playing. On the optical machine, Texas Instruments DLP Projection technology, resolution: 1280*800 , the dual light path optical engine makes the brightness reach 580ANSI Lumens, contrast up to 5000:1 , projection ratio is 1.2:1 ， two Can be cast at a distance of m seventy-six Inch image.

The following is a projection effect test. The test environment is in the bedroom with the lights off, not a full dark environment, because the bedroom door is open and the corridor light is on.

one Color saturation test: the more beautiful and transparent the color, the better.

two Gray scale restoration test: the smoother the color transition, the better.

three , proof sheet and complex scene test, mainly based on details and color restoration ability.

four , Blu ray video playback effect test.

five Test the effect of turning on the ceiling lamp in the bedroom.

From the above test samples, whether it is static picture display or dynamic video appearance, whether it is a small dark room or a room with lights on Z4X With the brightness guarantee of the dual light path engine, color restoration, light and dark details, and dynamic images are relatively good, and the performance in micro intelligent projection is satisfactory.

In addition, no matter how good a play is, it needs sound to set it off. Polar meter Z4X The sound system of is customized by Harman Carton. This brand is very famous Z4X It also has his certification mark on it. From the perspective of effect, the sound system performs well at all levels. As long as it is not too demanding, it basically meets most needs.

Speaking of sound, Jimmy Z4X It can also be used as a music player when it is turned off, and supports 3D With gesture switching, you can directly switch songs in online Baidu Music by scratching your palm on the "black glue disc" of the body. The sensitivity of motion recognition is relatively high.

"Heat dissipation effect, details that can never be ignored, no too many heat dissipation holes, but the effect is good"

For the sake of product beauty Z4X There are not too many heat dissipation windows on the fuselage, which mainly focus on the rear and bottom of the fuselage, and the area is not large. For projection, which is a big heat producer, is it worth the loss to let the heat dissipation give way to the appearance? Or is Jimi confident in the heat dissipation ability of the product?

The tail was tested for heat dissipation at room temperature twenty-four After playing a movie, use the instrument to measure the temperature of each position of the fuselage as follows: the temperature of the upper fuselage is thirty-four The temperature near the lens is about thirty-one The temperature of the side close to the cooling hole is forty-one The temperature on the other side is thirty-five The temperature of the rear cooling hole is fifty-one The temperature at the bottom is thirty-seven Degrees. From the results, Z4X Through the air duct design, effective heat can be emitted. I really have confidence in this aspect, and the heat dissipation ability is worthy of affirmation.

Concluding remarks

As can be seen from the above test Z4X The advantage lies in its fashionable appearance, good details UI Simple, excellent audio and video, excellent heat dissipation, built-in solid state disk, gesture recognition WIFI The distinctive characteristics of sound. The disadvantage is that the white matte body is easy to get dirty and hard to clean UI The scalability of the manual focus is insufficient, and obsessive-compulsive disorder suffers. In general, polar meters Z4X The overall performance is still at a better level.
