Foreword: In August just beginning, home-use smart projection leader Miji Technology has three new models of Mango Xiaofan, Z4X, and Z4 Air, which have been officially sold in the market. Among them, Z4 Air, a full-fledged commercial fan, is in short supply and is highly favored. Z4 Air is known as the thinnest HD smart projector in its history with its ultra-thin and stylish appearance. This iPad mini-sized projection supports 300-inch high-definition giant screens. It excels at business and office. It is also a portable and ultra-portable all-rounder.
Polar meters Z4 Air using black square box, from the packaging point of view may be difficult to guess it is installed inside a smart projection, apparently the thickness of the side is really too thin. But the Z4 Air is really inside.
The packaging adopts a three-stage removable design. The Z4 Air host and accessories are placed separately. It gives a very fresh feeling and it also looks noble.
The body of the product is affixed with a protective film on the fuselage, the protective film on the pole meter Z4 Air boot method and the key position instructions marked. It can be seen that the manufacturer is still very careful.
The Z4 Air is equipped with an HDMI cable, a remote controller, and a power adapter in addition to the host computer. The adapter plug part can be unplugged and used to match the foreign specifications. Such a detailed design provides convenience for international business friends.
The Xiaobian Z4 Air is a local gold, the product shell is made of high-quality Australian alumina, and the four-cornered arc design; the surface is processed by CNC precision machine tools, artificial fine wire drawing, high-strength sandblasting and anodizing etc. Nearly 100 complex processes, feel comfortable. Of course, as the same body with the Apple MacBook Air technology, in addition to enjoying its exquisite fashion, poor scratch resistance is inevitable. Although the official selection is equipped with a protective cover, but Xiaobian feel that the cover will not be too cool, especially this gorgeous local gold.
Known as the thinnest high-definition smart projector in history, the Z4 Air has a body thickness of only 23.5mm, which is astonishingly thin, and even thinner than the dial diameter of an ordinary watch. It is also equipped with a compact size of 113.5214mm. The Z4 Air, which weighs only 0.65KG, can be easily put into your carry bag without any pressure. Such a small and portable, it is taken for granted by business people.
Extreme Z4 Air uses a unique slide switch design that cleverly combines the dust cover and power switch. The sliding switch adopts the drawing process of 0.02mm kerf gap, and the pleats shine under the illumination of light and shine like a starlight. Not only is it fashionable and cool, but also it has a very comfortable feel. At the same time, it also has excellent non-slip effects. The most important thing is that the feeling of sliding is very comfortable. Slightly regretful is that the Z4 Air does not support auto-focusing, and it is necessary to manually adjust the focus adjustment wheel on the side to perform sharpness adjustment. Fortunately, it is not too time consuming, but it is also detrimental to Bigger.
The interface design of the Z4 Air is very rich. Including the charging hole, USB2.0/USB3.0 jack, HDMI interface, audio output hole, mobile power switch, support for USB external devices and high-definition picture quality output, but also an external audio device or insert headphones. In addition, the pole meter also supports WiFi hotspots and Bluetooth modules, can be connected through wireless operation, Bluetooth handle, audio, etc., super power.
Z4 Air's speaker holes are also placed on the back, using a rectangular matrix design, beautiful and generous. The Harman Kardon's sound unit is built into the fuselage, and the sound is excellent enough to meet the daily viewing needs. The side of the speaker hole is also designed with a bar LED indicator, used to display the Z4 Air battery power, can be considered more intimate design, but only the copper over the indicator color more than 50% and make a distinction More rough. It is recommended to replace the 4-5 pinhole LED display.
The Z4 Air's heat dissipation holes are designed on the front and right sides. The front heat dissipation holes are especially designed and very beautiful. Z4 Air has built-in ice nested graphene heat dissipation system, and the cooling effect is still worth the wait.
In addition to its conventional configuration, the Z4 Air is also equipped with a luxurious and stylish portable storage bag. The storage bag was placed in a paper bag that resembled a small portfolio. It was very thin, and Xiao Bian didn't really expect it to be a storage bag.
This custom-made Z4 Air-specific storage bag is reddish-brown and made of microfiber leather. It is very soft and comfortable, and the workmanship is also very detailed. A colored elastic band is designed at the opening of the receiving bag, which is used to tighten the opening after the meter is placed in the receiving bag. This design is very convenient. This product is not only convenient for users to store and carry, but more importantly is to protect the Z4 Air's metal shell, reduce scratching and super close. Of course, as a business person, when you come up with such exquisite noble rice from the bag, the people around you will surely have a bright future and can not help but be amazed.
Z4 Air uses 4-core 1GHZ CPU processor, Mali-450MP2 graphics processor. 1G operating memory plus 16G flash memory, can effectively ensure that all types of documents, ppt and other office data quickly open, video game smooth operation. At the same time the fuselage built-in South Korea LG 13600mAh high-energy battery, energy density of 725Wh/L, for Z4 Air in the absence of power supply in the case of continuous work 2.5H or so, so that business office, audio and video enjoy anytime, anywhere, arbitrary. Even more powerful is the Z4 Air battery can be used as mobile power for mobile phones, Pad and other mobile devices to charge, so that users do not have to carry another mobile power, there are energy stations at any time, business travel necessary artifact ah!
In the software, Z4 Air adopts the GMUI system based on Android 4.4 independently developed by Z4 Air, and the operation interface is very simple. At the same time, business office and leisure entertainment are divided into different versions and users can set the desktop version in the settings, which is convenient for users to directly enter the business office mode during business negotiation or other business, without popping up the content of the scenes such as movies, landlords, etc. . In the standard interface of leisure and entertainment, users can enjoy the fun. Movies, music, and games are all-encompassing, but also support the expansion of the App installation, giving users a rich content experience.
In the office mode of Z4 Air, a large-screen version of WPS is preset. From the main interface of the office mode, various office documents such as word, excel, and ppt can be opened, which is concise and fast, and effectively saves time. The only Z4 Air industry supports both Windows, OS X, Android, and ios systems with one-button projection. The user can download the meter assistant App to the mobile device, realize one-touch screen, resource delivery and control functions by connecting the wifi hotspots of the meters, and can also install the meter-like screen software on the computer to realize the display function of the computer screen. This eliminates the tediousness of the image transmission connection and allows the office procedure to be simplified again. In this business era, it is very powerful. At the same time, the mobile phone App supports the remote control simulation function, so that the user does not need to carry the remote controller. At the same time, it avoids the embarrassing situation that the remote controller is lost and ensures that the user's business display is perfectly safe.
In terms of leisure and entertainment, Z4 Air, together with Mango TV and Baidu Music, provided users with a feast. Including Mango TV's hundreds of thousands of video resources and Baidu Music's hundreds of millions of library resources; with 1080p ultra-high definition and 3D film area, giving users a higher quality audio-visual effects. What is even more powerful is the 24 hours worth of Mango VIP service which is worth RMB 740, which further enriches the user's audiovisual resources and privilege enjoyment. In terms of games, Z4 Air supports massive game downloads while supporting mobile-screen games. Users can use mobile phones to play games, which is very convenient. However, with the use of mobile games, there are screens appearing on the screen of the mobile phone. Obviously, the effects of the gamepad and the external game console are smooth.
Z4 Air uses a small remote control that is comfortable and easy to hold. The button design of the remote control is relatively simple. Some buttons serve more than two roles. Some specific functions and operations also need to be familiarized with in everyday use. However, the operation of the remote control is naturally not as easy as a mouse and a touch screen, and it is inconvenient to operate when there are many information input and selection items. Fortunately, the Z4 Air supports peripherals. Users can use external keyboards and mice to optimize operating efficiency.
Extreme Z4 Air uses a high transmittance coating lens with a projection ratio of 1.2:1, a nominal brightness of 250 ANSI lumens, a contrast ratio of up to 5000:1, a screen resolution of 1,280,720p, compatible with 1080p and 2K, and support for 3D video playback. Good depth of field and clarity.
In terms of picture quality, the Z4 Air adopts the most advanced TRP square pixel architecture from Texas Instruments and has 921,000 pixel arrays. At the same time, the pixel is optimized to a rectangle by the traditional diamond shape, the picture is more smooth and natural, and the text is more prominent. The use of 16 image enhancement techniques and 11 enhancement techniques as well as large screen optimization techniques on the screen processing allow the Z4 Air to display a good picture quality on the 300-inch screen. In addition, the fuselage built-in OPT3001 optical sensor I fusion ntelliBright technology allows the meter Z4 Air can measure light intensity, automatically adjust the screen brightness, enhance the picture contrast, give the user the most comfortable visual effects.
The following is the Z4 Air display screen shot by Xiao Bian in the dark environment:

Due to camera shooting, the display may be compromised. However, through the top a few real shots, we can still see that the Z4 Air is very good in terms of display brightness, color contrast, and clear and detailed image quality. Brightness and color projection are more uniform. The overall picture performance and scene performance are also acceptable. The rectangular pixel technology makes the text display very good. Even at close distances, the text is still sharp and sharp without glitches. . Of course, the brightness of the Z4 Air 250 ANSI lumens is still very limited, and it requires a relatively high degree of darkness. However, pricing and positioning are in place and it is impossible to have the same fitness as 1000+ lumens. In general, the Z4 Air can be used as a portable business office and simple home entertainment.
In terms of heat dissipation, Z4 Air has a built-in ice nested graphene heat dissipation system. Its thermal conductivity is more than 10 times that of metal materials, and its heat dissipation capability is very strong. At the same time, an adaptive system is integrated to automatically adjust the fan speed while effectively reducing fan noise. But what about Z4 Air's specific cooling effect? Xiao Bian used a professional thermal imager to test the heat dissipation of Z4 Air's work (playing HD movies) for 90 minutes. Details are as follows:
Thermal Imager Monitoring Results
Temperature recording curve (heat sink in front of the fuselage)
It can be seen from the temperature test results that the Z4 Air is very awesome in terms of heat dissipation. Because the shell is made of aluminum material, the temperature distribution of the upper and lower housings is relatively uniform, and the high temperature parts are located at the heat dissipation holes, indicating that the graphene heat dissipation system plays a very good guiding role. Within 90 minutes, the maximum temperature is 41.6°C, and it appears at about 30 minutes after starting up. After the fan's automatic adjustment function starts normally, the temperature at the later stage is relatively stable, and it stays around 41°C. As we all know, no matter how perfect the projector cooling function design, it is difficult to ensure that the projector used to cause high heat for a long time, but the Z4 Air in the small series of monitoring within 90 minutes all the temperature is stable at about 41 °C, it can be seen The cooling system is very good. Here Xiao Bian wants to praise Z4 Air's cooling function, super power. Compared to the excellent heat dissipation function, the Z4 Air's noise performance is normal, and the noise during the day is not very obvious. At night, if you deliberately listen to it, the fan noise is still quite obvious. Xiao Bian suggested here to continue to optimize the next period.
As a smart micro-projector with a price of 2,499 yuan, the Z4 Air is very good in terms of appearance, quality, operating experience and heat dissipation. In particular, its small and slim body shape, dual-mode interface of office entertainment, mobile power function is to let business people put it down. What's more, Z4 Air also has a huge amount of video and video game resources to support the expansion of personalized applications, entertainment and leisure are not behind. Of course, there is still room for Z4 Air to improve its brightness setting and noise handling. This will require the team of Miji to continue their efforts and give the user a more complete experience.
