After Z4 Air and Mango Xiaomi, the flagship machine Z4X of Jimi Technology has finally been unveiled to the public. This Z4X, named after the screen less super TV, is targeted at home audio and video entertainment. It introduces the Harman Carton sound system and a 0.45-inch dual light path ultra-high brightness light machine. It is known as a unique combination of audio and painting. It is one of the few tens of millions of products in JD crowdfunding. Xiaobian is lucky to be the first to get the opportunity to experience this product. Here is a brief introduction to this flagship machine.

The packaging box of Jimi Z4X is a square box with a length of 15cm and a width of 15cm. From the front, it is the same size as the Z4Air. However, the thickness is 2.5 times that of Air. It can be seen that the weight of Z4X top configuration machine in the same model of Jimi. The packing box is buckled up and down, and the design is simple and elegant. A color belt forms a circle to surround the "Z4X Screenless Super TV" in the center.

The bottom of the packing box is black, and the brand, partner, production company, equipment ID and other relevant information of the projector are printed on the lower left corner. What makes Xiaobian uneasy is that in front of Mango TV and Baidu Music, the partners, Harman/Kardon, which is the top brand in the world's first-class audio manufacturing industry, can be introduced into the sound technology of Harman Kardon by a home TV without screen, which is really surprising.

When we opened the box, Z4X with a layer of "tulle" appeared in front of us. It can be seen that the design of Jimi Z4X is a combination of square and round. The protective plastic layer of the sticker on the black disc in the middle briefly introduced the unique gesture control method of the WIFI audio function of Z4X. The product is surrounded by black fine foam, which effectively guarantees the safety of Jimi Z4X during transportation.

”Wisdom wants to be round, but action wants to be square ". Jimi Z4X integrates the philosophy of square and round into the design of product appearance. The white square body shows calm and neat, while the black disc in the middle brings a mellow and mellow visual experience. One square and one round, combining the two, is natural, elegant and full of charm. At the same time, the middle disc adopts the design of the classic vinyl record, which can't help pulling people's thoughts far away, as if the phonograph has been opened, and the film rotates slowly on the phonograph

Although the top disc is beautifully designed, it is not only a decoration, but also a gesture control area for WIFI audio function. The middle position is a touch button printed with "XGIMI", and the surface is treated with high gloss, which makes the touch feel very comfortable, but it is easy to get fingerprints. The surrounding "black film" sensing area is densely covered with progressive circles. The laser effect is very beautiful in the sun. A red bar indicator light is designed at the singing arm position, which is very creative and has a strong visual effect.

The lens position of Z4X is designed at the front side of the fuselage, covered by a dust cover. As the same as the two products, the sliding lens cover is still used for boot operation, which is simple and convenient. The difference is that the lens protection cover of the Z4X is embedded. To open it by sliding, you need to drag the sliding button below. The right side of the lens position is the horn hole of Harman Carton audio, and the nameplate of Harman Carton is designed at the prominent position in the upper right corner. The horn hole design looks casual, but with the lens position, the whole front side looks clean and elegant without any incongruity.

The lens of Z4X is designed with a dual light path optical engine, so it is obviously larger than the Z4Air and Xiaomi lenses. It is a highly transparent coated lens, which can project a 300 inch giant screen at most. However, compared with the first two products, the sliding damping of the Z4X lens cover is not very strong, probably due to the embedded lens cover, and the feel is slightly poor.

For the beauty of the product, Z4X places all the cooling holes and jacks on the rear side of the fuselage. The cooling holes are of oblique strip design, occupying half of the rear side. Z4X provides a wide range of interfaces, including one LAN interface, one USB3.0 interface and one 2.0 interface, two HDMI high-definition interfaces, DC IN (power supply) interface, AV interface, headphone interface and RESET interface. At the same time, it has built-in wifi and Bluetooth modules, which greatly enrich the external connectivity and peripheral support of Z4X.

The back of the fuselage is also square and round, and the black chassis is printed with some product information and caution icons. There are three feet with silicone surface and two silicone pads designed around. The three silica gel surface legs are actually three set screws, which can be unscrewed to install the special adapter plate for the meter, and used to connect the tripod or suspend it. At the same time, when the screws are unscrewed, the chassis of the Z4X can be turned to the right according to the arrow prompt on the upper side. The 2.5-inch hard disk space reserved for the Z4X supports high-capacity solid-state drives. For better heat dissipation, the Z4X is also equipped with rough heat dissipation holes at the bottom to effectively ensure rapid heat dissipation of the fuselage. Of course, this design also solves the heat dissipation problem of the built-in hard disk.

The accessories of Z4X are also very simple, with only a 15 key remote control and a power adapter. Although the remote control is also set with 15 keys, it can still be seen from a closer look that it is different from the remote control worn by Z4AIR and Xiaomi. The original quick screenshot key and 3D switch key have been replaced with the electric focus control key, making the focus operation more rapid and convenient.

The maximum rated power of Z4X is 90W, and it adopts the direct power supply mode. The power adapter is produced by Delta Electronics Industry, and the output is 19V/4.74A, split type. The materials are exquisite and the workmanship is solid. It would be even better if a power supply indicator was added.

As a home screen less TV, the elegant appearance design of the Z4X can make it well integrated into various styles of home environment. Z4X can be easily placed in TV cabinets, closets and even bedside tables.

Of course, the intimate design of Z4X can satisfy you more. In addition to the accessories in the package, the Z4X also provides a specially customized adapter plate, which can be installed after the three foot bolts at the bottom are removed. After installing the adapter plate, it can be installed with the hanger or tripod. What is more powerful is that the official Jimi has also launched a variety of special brackets, so that the Z4X can be easily hung on the wall or clipped on the bedside, elegant or comfortable, as you wish.

Unlike Jimi Z4Air and Xiaomi, Z4X only supports DC power supply. It is a pity that the Z4X does not support the "offline" operation of the built-in battery. However, in the face of the relatively large power of the Z4X, the capacity and weight of the built-in battery are difficult to solve in order to ensure at least 2 hours of use time. In terms of the size of the Z4X and its positioning in home entertainment projection, the outdoor use of the Z4X is relatively small. I understand this practice of Jimi.

The Z4X uses a high transmittance coated lens and a long-life LED light source, with a built-in dual light path optical engine, and uses the DLP optical projection technology of Texas Instruments in the United States. As a micro projector, the Z4X has achieved 580ANSI lumens in brightness, which is currently the highest in similar products. The resolution is up to 1280 * 800, making Z4X compatible with 4K resolution and clearer in image quality.

Z4X adopts MStar quad core (A9) 1.5GHz 4K intelligent TV processor, Mali-450MP4 graphics processor, 2G running memory and 16G flash memory. Both the CPU, GPU and running memory are higher than the previous two products. It can be seen that the official price of the flagship Z4X is high. In terms of software, Z4X adopts the GMUI system independently developed by Jimi based on Android 4.3. Through 3D multidimensional layout, the page is simpler, easy to operate and easy to use. In addition to the ultra-high precision electric focusing technology, users can easily enjoy the 100 inch cinema with one button.

Focusing on home TV without screen, the film and television resources of Z4X cannot be missed. Z4X still cooperates with Mango TV and Baidu Music, and the film and television music resources can be described as infinite. At the same time, a 24 month mango VIP service worth 720 yuan will be given as a gift, so that the legitimate film and television can be seen first, and there is no need to wait or have no choice to see the pirated version. At the same time, there is a special 3D resource area, so there is no need to worry about the problem that 3D resources are hard to find.

In 3D technology, Z4X adopts the same active shutter 3D imaging technology as DLP Cinema movie projector, which is more bright and stereoscopic than ordinary dual polarized 3D cinema. With the customized 3D active shutter glasses (to be purchased separately), it is like an IMAX cinema at home, wireless and cool.

It is well known that the car audio of Mercedes Benz, BMW, Land Rover and other luxury cars all use Harman Carton, the top audio brand in the United States. The sound system of Z4X is customized and carefully tuned by Harman Carton. The power amplifier adopts the ultra-low distortion digital power amplifier of American TI company, coupled with the crystal loudspeaker of Harman Carton, which brings excellent sound quality analysis ability and shocking low-frequency effect. At the same time, 3D surround effect is added to make viewing very exciting.

In addition to the excellent sound quality, Z4X also brings the original WIFI audio mode. Users do not need to open the screen, and gently press the logo button on the front of the fuselage. Z4X will automatically connect to WIFI, and Baidu Music will sound. In WIFI audio mode, users can perform gesture operations above the "black film", and support gesture song cutting, volume increase and decrease and other operations. The built-in 3D gesture recognition chip can determine the position with 150 dpi accuracy, and the recognition rate can reach almost 100%, which is excellent. With Jimi Z4X, you can easily lie on the sofa or in the cane chair and enjoy music lazily.

Z4X not only has powerful audio and video functions, but also has a built-in game hall, which contains rich large screen games, simulator games, etc., and supports PS, XBOX and other peripheral game consoles. Users can easily enjoy the fun of games. Xiao Bian simply tried the next two racing games, including the best racing game that is often used to carry out system operation ability. The game has clear picture, smooth operation and no jam, plus the powerful visual sense brought by the large screen, and the stimulation of the game is realistic, which is really a magic tool for work decompression and family entertainment.

In addition, Z4X has a wealth of built-in application resources, including news information, life services, children's education, fitness and beauty and other categories, which can meet the needs of each family member. Compared with a small mobile phone, it must be comfortable to lean on the sofa and enjoy the giant screen experience brought by the Z4X.

In addition to the above resources, the Z4X also supports the one button one screen function of the phone's polar assistant. Users can easily put resources in the phone with one button through the polar assistant, or they can directly operate the Z4X or play games on the phone. It not only expands the resources of Z4X, but also enriches the operations of Z4X. It is easy to use.

Another powerful design of the Z4X is that it has a built-in solid state drive compartment, which can expand the storage capacity. Cooperate with Xunlei remote control download function. Users can use their mobile phones or computers to remotely control and download their favorite movie resources, use their leisure time to download their favorite movies, and avoid affecting their viewing experience due to network speed and other reasons, which is very humanistic.

The Z4X 0.45 inch DLP light machine adopts a dual light path optical engine, in which the color management engine optimizes the color mixing of each frame with reference to the digital projector color standard DCI-P3 to restore the film master color. At the same time, Texas Instruments' DLP optical projection technology, 16 image quality enhancement technologies, and 11 colorful enhancement technologies make Z4X very outstanding in image quality performance. The contrast of 5000:1 plus nearly 30% brightness improvement of 580ANSI lumens make Z4X more skillful in color restoration, color saturation, fine pitch processing, etc. It is really the flagship machine of home screen less TV.

Let's take a look at the display capabilities of Z4X in color processing, high-definition pictures and high-definition movies.

PS： Although the brightness of the Z4X has improved, it is still not suitable for daytime viewing, so the test environment of the small editor is still a dark room. At the same time, due to the small photographic equipment and technology, the photo effect should be discounted from the actual effect. I hope you will understand.

From the above test photos, we can find that the improvement of the brightness of Z4X and the dual engine technology have improved its color performance compared with Z4X and Mango Xiaomiu, especially when the color effect and gray scale are tested, the effect is more obvious, and the color and detail performance are more in place. The performance of high-definition pictures is amazing. The color is saturated and has tension, while it is delicate and smooth. The performance of the film's picture quality is also very good. The performance of the depth of the road, the sense of hierarchy, and the skin color details of the close range characters are all in place. In addition, the presence of the 100 inch giant screen is very shocking.

In terms of heat dissipation and noise of the product, Jimi has always done very well. The temperature data of Z4Air has been tested with a professional thermal imager before, and the results are quite satisfactory. But today's Z4X has improved its brightness and power. How about its cooling effect? The editor tested the thermal imaging temperature of Z4X, which played high-definition movies continuously for 2 hours at room temperature of 25 ℃. The results are as follows:

▲ Front temperature

▲ Top temperature

▲ Side temperature

▲ Rear temperature

▲ Bottom temperature

It can be seen from the above thermal imaging data acquisition results that the heat dissipation capacity of Z4X is very excellent. Thanks to the polar meter heat dissipation design and heat dissipation media, the Z4X has not experienced excessive temperature due to increased power. From the above results, we can see that the heating capacity of Z4X is much higher than that of Z4Air and Mango Xiaomi. The maximum temperature of the heating area in the bottom area reached 60.3 ℃, and the temperature of the rear cooling hole reached 46.1 ℃. However, it can be seen from the point temperature in the figure above that the average temperature of the case of Z4X is about 34 ℃, and the maximum temperature at the edge of the cooling hole is only 38.1 ℃. That is to say, most of the heat of the Z4X is discharged well without being trapped in the body. The body is close to body temperature in the sense of touch and touch, and the rear area may be slightly hot, but this performance is already excellent.

In terms of noise, the Z4X is larger than the Z4Air, but it is almost invisible if you don't listen carefully during the actual viewing process. The official data is less than 30dB, which is very satisfactory.

Finally, the detailed parameters and packing list of Jimi Z4X are attached:

Conclusion: As a non screen TV with fashionable and unique appearance, excellent sound quality and image quality, and high quality WIFI audio function, the performance of the Z4X is undoubtedly very excellent, which can be described as "beautiful and intelligent". The design of gesture recognition operation and built-in SSD expansion function also adds color to this screen less TV. Although the white polymer material on the surface is easy to get dirty and difficult to clean, and the brightness of 580ANSI lumens is not enough to cope with all-weather conditions, as far as the current domestic industry is concerned, the Z4X is definitely the No.1 product at the same price. Its accurate market positioning and price advantage (only 2699) are enough to make the Z4X become the focus of attention. Owning a Jimi Z4X is equivalent to owning a private theater, and the supreme "emperor" will always be waiting for you and your family.
