With the progress of material life and the rapid development of smart home, a variety of smart products have emerged one after another. TV sets have already entered the intelligent era, and the size is getting bigger and bigger. However, the projector is still a huge screen that cannot be reached by TV sets, which has always been the dream of many people top-level Home entertainment equipment, after years of development, intelligent projection came into being, that is, super screen less TV, which subverts the concept of TV. Why subvert it? First, this mode of watching TV is difficult for ordinary users to enjoy before. Second, the advantages of screen less TV are sufficient to support the new trend of future TV development, but the development of technology has been repeatedly verified, In practice, XiaoBug has recently acquired a super no screen TV, the Z4X, which is not a portable product like the Z4AIR and Mango Xiaomi in the same series, but a living room cultural ecology. Let's see how this intelligent projector with cultural connotation performs.
Breaking the conventional thinking, exquisite projection is born for the living room culture
As a new generation of intelligent projection, Z4X is a boutique product in terms of packaging, products and accessories. Its exquisite vinyl record style and appearance, as well as the oriental cultural connotation of "Wisdom desires its integrity, and action desires its squareness", demonstrate a taste. Compared with many similar products on the market, this unconventional design concept has improved the comprehensive quality of products to a new height.
The white environmental protection paper box is packed with colorful rings on the front, the Z4X product name in the middle, the black inner box, and the product information printed on the lower left corner of the bottom. There is not too much decoration on the whole, simple and generous. The Harman/kardon logo on the side and bottom of the box makes us look forward to the sound effect of this screen less TV, In addition, the 3D glasses and adapter plate are separately packaged.
There are two layers in the box, the upper layer is the Z4X host, the lower layer is the accessory box, the middle is the manual and warranty card, and the foam shock absorption is used around the box. The top surface of the host is also pasted with a protective film. The protection is still in place. All items include the host, remote control (button battery), power adapter, power cord 3D glasses (charging line, storage bag, lens wiping cloth), adapter plate, hard disk fixing screws, Mango TV two-year VIP card, you can see that as an intelligent projection used in the positioning living room, this machine has relatively rich accessories.
The Z4X is made of high-strength engineering plastic shell, which is square in shape. The white plastic shell is made of frosted surface. The top of the round black glue turntable is shaped as a gesture sensing area. The bottom base is also black. Product information, various identifications and precautions are printed in the middle. Air inlets are designed on the left side of the base, all of which are equipped with fine steel wire mesh to prevent dust and small flying insects from entering, Three round bolts and two anti slip pads support the base. Remove the screws to remove the bottom cover. Turn the red indicator point to green in the direction of the upper arrow to open the hard disk cage.
The left lens position on the front uses the same sliding switch as Z4AIR and Mango Xiaomi. The projection can be turned on and off when the cover is opened and closed. As a screen less TV in the living room, The sound system of Z4X is customized by Harman/Kardon Company. The rear side of the machine is the interface area and cooling holes. The interface area is reasonably arranged, neat and beautiful. The cooling holes are composed of a group of diagonal holes, and the internal cooling fins are clearly visible.
Both inside and outside, intelligent projection can also be elegant, not like the strength school
It is believed that everyone is familiar with the clumsy image of traditional projection. In this era of face value competition, intelligent projection has launched a counter attack on face value. The Z4X is the best in both external details and internal performance, which is totally not as elegant as the strength school.
The biggest feature of the appearance design of this intelligent projection is the design of the black vinyl turntable on the top. Its design implies the oriental cultural connotation of "Wisdom desires its roundness, and action desires its squareness". This unconventional design idea can be said to attach an elegant label to the living room culture. It is also a design point that I like personally. The circular drying process is full of a sense of age, With the red LED indicator light at the lower right corner, it is not only decorative, but also indicates the gesture control area. It is elegant and practical, which can be said to be ingenious.
The logo of Harman/Kardon on the right side of the front of the host is very eye-catching. The sound outlet composed of random lattice holes is like a spiritual note, personalized and flexible. The use of crystal sound speakers and professional tuning, together with the low distortion power amplifier of Texas Instruments, makes this product have a clear and delicate pure voice, more in line with the projection positioning of the living room, The original sliding cover switch combines the dust cover and the power switch into one. When the sliding cover is moved, the switch is projected. This simple and natural operation is integrated into the pragmatic design.
From any point of view, Z4X can reflect the bright side. With its current positioning, it should be located in the living room, bedroom, and single apartment, which are not very large. This can better reflect the sound effect, and the movie experience will be better. The rich interfaces can also meet the needs of daily use, The RJ45 network interface can make the connection more high-speed and stable. It is undoubtedly a blessing for users with high demand for 4K movie source viewing. The two USB ports can choose to access peripherals such as flying mice, game consoles, and two HDMI interfaces can connect to high-definition playback devices, computers, and so on, The AV port can also be easily connected to older video source equipment, and can also be output through the headphone hole to meet personalized audio connection requirements.
In addition to the unique design in appearance, this projection uses a 1.5GHz quad core processor, Mali-450MP4 graphics processor, 2GB DDR3 dual channel memory, 16GB eMMC high-speed flash memory, and the operating system is a GMUI system developed in depth based on Android 4.3. The interface is simple and intuitive, and the operation is smooth. Compared with many network set-top boxes or smart TV systems on the market, GMUI system is very perfect and easy to use. In terms of resources, through cooperation with Mango TV and Baidu Music, we have obtained very rich audio and video resources. As a TV product, this experience foundation is quite good.
LED projection brightness has been improved, and multiple technologies have enhanced image quality
After experiencing many intelligent micro investment, I can see the projection effect of the Z4X. The deepest feeling is the improvement of brightness and excellent picture quality. The overall performance is eye-catching. (Note: The following pictures only cut off the black edge, without any other editing)
Z4X adopts Texas Instruments DLP projection technology, 0.45-inch DMD RGB LED chip, high transmittance coating lens, 180 inch giant screen projection, brightness can reach 580ANSI lumens, brightness uniformity value 98%, color gamut ≥ 120% NTSC, contrast 5000:1, standard resolution 1280 × 800, compatible with 1080p/2K/4K, and practicability for a household projection is also greatly enhanced, From the above live test pictures, we can see that its color and contrast performance is really good.
The above group of static pictures show more comprehensively the performance of this projection in the picture quality. The color is pure, the saturation is good, the details are complete, and the contrast between light and dark is strong, giving a delicate and real feeling.

(Ultra clear film: super body)
In terms of video and audio, Z4X inherits the characteristics of good image quality of Jimi projection. Although it uses diamond shaped pixel arrangement, it tries to restore the original picture in image quality through the "Jicai" color management engine and Texas Instruments DLP cinema technology. With the high-quality sound of Harman/Kardon, watching movies at home becomes simple and refreshing.

However, LED projection generally has the problem of low brightness, and it is difficult to obtain a better viewing experience in natural light environment. The Z4X uses a well-designed dual light path engine, which has greatly improved the brightness of the screen, reaching 580ANSI lumens. It has obvious advantages among similar products. From the above comparison, it can be seen that even in a strong light environment, It is still possible to watch the program clearly, and the experience has improved a lot. The following evaluation is also conducted in the light environment, and it can be seen that there is still a good effect.
Strong performance, very comprehensive design as the projection function of the living room
In addition to the performance of audio and video, smooth and easy to use operating system, and the cultural connotation of integrating into the home decoration environment, the performance of home living room projection in terms of comprehensive quality also greatly affects the use experience. Next, the comprehensive performance of Z4X is reflected through 3D movie experience, game trial, calorific test, gesture operation, installation of hard disk box and adapter plate and other functions.
The Z4X comes with an active shutter type 3D glasses. The 3D play screen can be accessed through the 3D switch button on the remote control. The glasses will automatically open and close the shutter synchronously according to the current picture, which is convenient and power saving. The 3D presence is also strong.
Gesture manipulation is also a major feature of this projection. You can perform the previous and next song by brushing the top of the vinyl disc from left to right across the air, while you can perform the volume operation by rotating clockwise and counterclockwise, which is very special.
(Use flying mouse for operation and text input)
(PPT document demonstration effect)
It is very convenient to connect the keyboard and mouse for operation and text input. It is also quite enjoyable to post microblogs on TV. Here we recommend flying mice. After all, it only takes one USB port and has keyboard and mouse functions at the same time. The support for playing videos and demonstrating OFFICE documents is also very good when you insert a USB flash disk or connect to a shared disk in the network through SAMBA.
In terms of games, it is very convenient to play games by connecting the handle through wifi, and try out the football and fighting games that Bugs prefer. The operation is very sensitive, the picture quality is clear and smooth, and there is no jam, splash screen, flash back and other situations. The game experience is very pleasant.
After a lot of trouble, the temperature of several parts of Z4X was detected. The body temperature was about 32 ℃, and the highest temperature was about 39 ℃ at the air outlet. It can be seen that the heat dissipation effect was relatively ideal. However, the noise control of the machine was still in place, the fan efficiency was high, and the sound was not too obvious.
(Hard disk bin)
As a living room projection, hoisting is also the choice of many family users. The original Z4X is equipped with an adapter plate. Remove the three screws on the base cover. If necessary, the hard disk can be loaded into the internal slot of the bottom cover in advance to realize the remote download function. The installation is not complicated. Remember to screw on the small screws attached to the hard disk after inserting it.
After installing the hard disk, fix the adapter disk on the base, and use the standard screw suspender to safely hoist it on the ceiling. Here, use the standard triangle bracket to demonstrate the effect of connection, but it is better to reserve the power cable, network cable HDMI HD cable and other required wires and sockets, but the gesture control can not be used after the lifting method is adopted, which is a little pity. So I personally prefer to use the support method. For such a smart projector with high appearance, strong performance and fast system update, more functions cannot be demonstrated one by one, and interested friends can purchase one, Let's have fun with our friends.
epilogue
Through recent use, I have gained a more comprehensive understanding of this Jimi Z4X. In terms of appearance, this projection has changed the dull shape of the traditional projection, and integrated cultural and fashion elements, so that the screen less TV can also enter the room. In terms of audio and video, through the "Jicai" color management and the DLP cinema technology of Texas Instruments, the quality of the original painting can be restored to the greatest extent, With the Harman/Kardon high-quality sound system, it brings a shocking viewing experience. The carefully matched interfaces and gesture operation methods make projection more convenient and practical in use. The price of less than 3000 yuan does not appear to be too high. 3D glasses, adapter plates and other accessories are also included. Among similar products, the Z4X is still very cost-effective.
