With the constant updating of various intelligent products, the market of home projectors has also begun to heat up recently, and intelligent micro projection devices have also begun to enter our daily life. As a leading innovative enterprise of intelligent micro projection in the industry, GIMI Technology is committed to the research and development of screen less super televisions (projection televisions), and as the final work of GIMI in 2015, Jimi released its latest flagship product, the Jimi Z4 aurora. Compared with the previous generation of the Jimi Z4X, the Jimi Z4 aurora not only has brightness increased to 600ANSI lumens, but also is equipped with the left and right trapezoid correction function that used to only appear on the 10000 yuan projection. How about the performance? Let's test this projection device.

Unpacking&Appearance:

The Z4 Evoque is a black paper box, with the words "Z4 Evoque" in the middle of the front and a small line of characters below it, "Z4 TV without screen". This is also the positioning of the product, not just a projection. The logo of Z4 Aurora is surrounded by a colorful gradual circle, and the overall design is simple without losing atmosphere.

The bottom of the back of the box is printed with some information about the partners. The Z4 aurora is jointly created by Harman/Kardon, Mango TV and Baidu Music. In addition, there is a brief introduction about the device model and functions.

The packaging box of Jimi Z4 Evoque adopts a combined design

Then it is divided into three parts. The internal packaging box is in rose gold background, and the icon is in Tuhao gold color, giving a low-key and luxurious feeling. The host of the Z4 Evoque is placed in the middle box. The box on the left contains 3D glasses, and the box on the right contains remote control and power adapter.

The above is all the accessories of the Z4 Evoque. The power adapter is very similar to the power adapter of a notebook computer. Of course, this is not universal. In addition, we are equipped with two pairs of 3D glasses and a Mango VIP membership card worth 720 yuan. Mango TV provides us with rich content resources. Through the new 2D to 3D function of the Z4 Evoque, We don't have to worry about the shortage of 3D movie sources, we can enjoy the shocking experience of 3D movies at home.

The body of the Jimi Z4 Aurora is made of magnificent gold, and the surface has been sanded to prevent fingerprint contamination. The classic vinyl record player design elements are integrated into it. The vinyl record design on the top is not only a decoration, but a control system with gesture recognition and touch switch. The black "XGIMI" logo in the middle of the top It is a touch switch, which can start/stop and pause/play music.

The front side of the Z4 aurora fuselage is equipped with a lens using the German OSRAM LED light source, which is energy-saving and environmentally friendly, without radiation and eye injury; Z4 Evoque adopts the sliding cover switch design, which combines the dust cover and power switch. The sliding cover is made of plastic material, which will give a sense of cheapness when sliding, which is not as good as the metal sliding cover design of Mango Xiaomi. There is a silver "harman/kardon" logo in the upper right corner of the front of the fuselage, which shows its excellent sound effect. The actual experience is really good. The sound adopts irregular porous design and integrates with the fuselage.

All the sockets of the Z4 Evoque are centrally placed on the back of the fuselage. It has 1 LAN interface, 1 DCIN interface, 1 USB3.0 interface, 1 USB2.0 interface, 2 HDMI interfaces, 1 AV interface, 1 headphone jack and 1 RESET jack. The external interfaces are very rich and can meet various needs, The addition of LAN interface is also very good. It can adapt to more different network environments, making the Z4 Aurora more flexible. There is also a large area of long grid area on the left side of the back of the fuselage. This is the heat sink of the machine. You can vaguely see the silver fins inside. It supports automatic and manual wind speed regulation.

At the bottom of the machine is a removable plastic base, which is printed with some simple information about the polar Z4 aurora. Three screws fixing the base are ingeniously designed as anti slip pads. The opening method of the back cover is also very simple. No tools are needed to directly unscrew the screws with the hand interface. After opening, we can see that there is a hard disk compartment inside, and there is a layer of sponge pad in the hard disk compartment. The details are also very good. It can be put into a 2.5 inch solid state disk, and it does not support the access of mechanical disks.

In the packaging box, we are also equipped with a bracket adapter plate, which can be assembled manually, equipped with a camera tripod, and then combined with the latest left-right trapezoid correction function of the Jimi Z4 Evoque, we can put it anywhere in the home. Because it is mainly used in families, the Jimi Z4 Evoque does not have a built-in battery, Therefore, the portability will be slightly inadequate.

The remote control of the Jimi Z4 Evoque is also a new design. It uses a very textured metal shell. It is the first time I have seen a remote control with a metal body. Compared with the previous remote control made of plastic, it has significantly improved both in grade and feel. The front of the remote control adopts a 12 key design, and the bottom has a Reset hole, a Micro USB socket, and a focusing switch button. When you dial to Focus, you can use the volume key to perform the electric focusing operation.

System&Experience:

After the Z4 aurora is connected to the power supply, click the XGIMI logo on the front of the body to start the machine. Without opening the lens cover, the system will automatically enter the music playing mode. With Li Jian's "reserved" singing, we first felt the strength of the Harman Carton sound system. After startup, the system will have a detailed introduction to the operation of graphics and text plus voice. We just need to follow the system step by step. In order to give you a comprehensive understanding of the projection picture of Jimi Z4, the following pictures are all live projection pictures, only the size of the picture has been modified and screenshots have been taken, without any beautification.

Jimi Z4 Aurora adopts the GMIUI system based on Android 4.3, which is a card design. If you have used Xiaomi Box products, you will be familiar with the UI interface of this system. There are four options on the main interface: film, music, games and applications. The installed applications and games are concentrated in the right area.

The film and television resources in the Jimi Z4 Aurora are provided by Mango TV. After entering the various classification interfaces, there is a sign of Mango TV in the upper left corner of the interface. Mango TV provides the Jimi Z4 Aurora with 3000 films and more than 100000 episodes of TV content. With the free Mango VIP card, you can watch more film and television programs.

The content resources in the "Music" option on the main interface of the system are supported by Baidu Music. In addition to online music listening, there are special radio channels to meet the needs of different people.

The game resources in the Jimi Z4 Aurora are very rich, and the game classification is also quite detailed, which makes it easy for everyone to find the game resources they want. I prefer arcade games, and there will be corresponding experience tests later.

There is also a special application option in the system to download applications, but there are too few application resources in it. It can be said that there are few practical applications in it, but it is still necessary to enrich application resources. Through the "application management" option here, you can uninstall, forcibly stop and clear cache the installed applications.

Enter the system setting interface, there are six setting options: network setting, Bluetooth&peripherals, projection setting, general, user and about. The left and right trapezoid correction function newly added to the Jimi Z4 aurora is adjusted through the "trapezoid correction" option in the "projection setting". However, at present, trapezoid correction can only be adjusted manually, and the system cannot automatically recognize the adjustment, It is recommended to add an automatic adjustment or restore function, or readjust after changing the position.

Above, we have made a brief understanding of the system of the Jimi Z4 aurora. The Jimi Z4 aurora uses 16 image quality enhancement technologies and 11 colorful enhancement technologies, but it makes the picture exquisite and smooth, colorful, and the brightness has also been improved to 600ANSI lumens. Of course, the above are official data. Let's go to the real experience. We still use more projection at night, thanks to the fact that the Z4 aurora has 600ANSI lumens can also be viewed normally indoors in the daytime, and the overall picture will be white. The above is a projection image taken indoors with curtains closed. Due to camera shooting, the actual effect is stronger than the photo effect.

At night is the time when our Jimi Z4 aurora gives full play to its powerful functions, so that you can also enjoy the cinema level effect at home. Through the comparison of the above pictures, we can see that the Jimi Z4 aurora is very close to the original picture at night when the lights are off, and the color is even more beautiful than the original picture. After the lights are turned on, the picture will obviously feel white, But the picture quality is also very good.

The above contrast photos of the pictures have not been optimized in any way. They have only been cut and resized. The Z4 aurora also supports 4K video playback. In order to show you a more realistic projection picture of the Z4 aurora, I will directly show you two original projection pictures taken here. After turning on the light, the projection picture will be slightly white. Of course, the actual picture is better than this because of the camera shooting. Let's leave it to you to comment on the effect.

The game resources in the Z4 aurora are also rich. With a Bluetooth handle, you can enjoy the fun of super large screen games. With the Harman Carton sound effect system, the game effect is very powerful. In addition, the remote control also has a gravity sensing function, which can directly play gravity sensing games.

In addition to watching movies and games, Jimi Z4 Aurora has a business mode. In the office mode, a large screen version of WPS is preset. From the main interface, you can quickly open a variety of office documents, such as word, excel, and ppt. The characters projected are clear. When you get close, the font looks old and round without sawtooth.

After the upgrade of the system version of the Z4 Evoque, users are no longer allowed to install applications at will, so we can no longer directly use the Z4 Evoque to watch live TV. Until there is no cracking method, we can easily watch live TV with batteries through the rich external interfaces of the Evoque. The method is very simple, one is to use mobile phones to cast screens, The other is to use the TV box. The method is very simple, so I won't say much here.

We can realize the functions of remote control, application installation and screen projection of mobile phones through the Kimi "Screenless Assistant" APP on the mobile phone. We won't introduce them in detail here. I don't know why my Xiaomi Note mobile phone and Xiaomi 4 can't open the Screenless Assistant APP after they are installed. The operation is also very simple. If you are interested, you can find out for yourself.

[Conclusion]

As the end of the year of 2015, the Z4 aurora of Jimi Technology, while continuing the high performance of the previous generation of the Z4X, has improved its brightness to 600ANSI lumens, and for the first time, it has also added the left-right trapezoid correction that used to only appear on the 10000 yuan projection, giving us a new experience of watching movies. Of course, due to the brightness of projection, it is still impossible to compare with TV in the daytime, but it can also be used; At night, it can bring you a visual feast. In terms of price, the official website currently sells for 3799 yuan, which is still the highest cost performance among similar products. My favorite friends don't pay much attention.

Shortcomings&Suggestions: The appearance design of the Jimi Z4 aurora is very unique, but the material and opening mode of the sliding cover switch are slightly different from the overall positioning, which will give you a sense of cheap operation; After adding left and right trapezoid correction, it can only be adjusted manually without automatic trapezoid correction function. If automatic correction can be added, it will be more convenient; There are too few resources in the system application store to meet the installation needs of everyone for the application. At present, the installation of applications outside the application store is also prohibited, which seriously affects the use experience; With the Xiaomi note phone, the "no screen assistant" of Jimi cannot be enabled, nor can it be used after replacing Xiaomi 4; The last thing to talk about is of course the brightness lumen. If you want to get a better viewing experience in the daytime, you can only continue to improve the projection lumen.
