Television is an invention that subverts the human lifestyle. Its appearance has changed the public's vision. For a long time, television has always occupied the people's living room, but can we not see the world that is not in front of our eyes when we leave the screen? Of course not, there is a projector. However, projectors have been mostly used in office areas and have never been able to go into the home. 
Unpacking
The first impression of Z4 Aurora, a screenless TV with extreme meters, is "subversion". It's hard to imagine such a product will take so much attention to packaging, and this premium package also highlights the high-end positioning of the Z4 Aurora. . In fact, the size of the host of the Z4 Aurora is not large, but what kind of surprise will be hidden in the atmospheric packaging box? 
In addition, the official claimed that the longest battery life can reach six months, although the hard egg Jun did not use the Z4 Aurora in close contact with such a long time can not confirm the official statement, but the use of two weeks has not been charged, the life can still make people satisfaction. 
Outer Form
The vinyl phonograph styling fuselage really brightened the dog's eyes of the tough egg king, completely subverted the hard egg prince for the projector's cognition, this mix and match gave the extreme Z4 Aurora distinctive atmosphere, after all, the more classic, The more popular it is. It's hard to find any connection between a vinyl record player and a projector. Is this design just for the sake of innovation? The vinyl record player can be said to be a subversive invention at that time. Does the Z4 Aurora, a non-screen TV with no rice, implying that Miji hopes this product can subvert people's lifestyle like a vinyl record player?

Since the projector needs a plane at work, it can only project an image of squareness in an absolute plane. Therefore, when using a projector, it is unavoidable to adjust the screen, and it is no longer difficult for the projection technology to adjust the screen today. 
Feature Features
Although Kami Motivation does not have a screen TV, it is essentially a projector. Standing on the projector's point of view, the picture under normal light during the day has been very good, but there is still a certain gap compared to the TV's daytime display. In addition, the polar meters Z4 need to maintain a certain distance to obtain the best results when the aurora is viewed. If the distance is too close, there will be a grid on the screen, which is the same for most large-screen TVs. 
UI experience
The Z4 Aurora Polaris has its own GMUI system, which is based on the Android 4.3 customization. It is not much different from the UI of TV boxes currently available on the market. From the user's viewing angle, the icon has a larger size and is clear at a glance. The difference is that, considering the needs of the business office of the user, the meter has a business desktop in the UI and can be freely switched on the UI desktop, allowing the user to use the required office suite more intuitively and improve the user experience. The efficiency of work. 
Summary of parameters
The following parameters are from the official website: 
advantage:
Packaging high-end atmosphere on the grade, rich accessories;
The appearance is novel, the classic of the vinyl record player is copied, and at the same time, the taste of the Z4 Aurora of no-screen TV is given to the meter, and the golden light color highlights the fashion taste;
Equipped with a million-square left and right trapezoidal correction, it can project a perfect picture at any angle;
The professional-grade Harman Kardon audio system is as effective as professional audio;
600 ANSI lumen projection screen effect, the maximum projection size of 300-inch visual experience shocked;
Metal remote control is powerful, rechargeable, Bluetooth connection, long standby time, both electric focus, voice operation, squirrel, somatosensory operation and game controller functions;
The human-computer interaction is outstanding, covering the current mainstream control methods such as buttons, touch, body feeling and voice, which breaks the barrier of human-computer "communication";
The addition of an independent business UI satisfies the needs of users with business needs to work efficiently;
The video source 2D to 3D function maximizes the user's demand for 3D film sources.
To be improved:
The lens slide can only be operated manually, and in some special situations, such as lifting, the user is inconvenient to manually open the lens cover, so adding a remote control lens cover opening function will be more humane;
The mobile phone uses the meter assistant to operate synchronously with the screen. The meter Z4 Aurora is fluent and has a high requirement for the network environment.
Does not support auto focus and auto keystone correction, although the opening of the opportunity to auto focus, but in the projection process to change the position of the host must manually focus, trapezoidal correction is always to manually adjust. If you can add auto focus and auto keystone correction, reduce the user to manually adjust the projection screen, then the polar meter Z4 Aurora will be more perfect performance;
Although the projection effect during the day is better than that of the projector, it still cannot compete with the traditional TV and remains to be improved.

Atmospheric gift box packaging
Z4 Aurora, a non-screen TV with no screens, is the end of 2015 and is a home projector that represents the current high level of technology and technology. Gift box opening
Expanding the box to make him feel like it is more like a "combination speaker", there are heaven and earth on both sides, hidden on the left two 3D glasses. Do not think that only 3D glasses in the box only glasses, the package is also loaded with a very rich variety of accessories, each eye with a charging cable, glasses cloth and glasses bags, also sent a nose pad. Of course, Lloyd is not as good as Lele. Good movies should be shared with close people. Two 3D glasses also allow users to share 3D movies with people around them. "Combined sound" +3D glasses display
In addition to the power supply of the bottom-level Z4 Aurora, the right side of the "combination audio" is only the metal remote control, which seems to be the first remote control using a metal material in the polar meters, not just the material change. The functions of the remote controller are also fully upgraded. First of all, from the data cable next to the remote control, we faintly guessed that this remote control uses a rechargeable lithium battery instead of a dry battery. The main reason should be that in addition to the remote control function, the remote control of the Z4 Aurora Polaris also has a flying squirrel and gravity sensing function, and the capacity of ordinary dry batteries cannot meet the life requirements of the remote control. Multifunctional metal remote control
The adapter plate is also considered to be due to the fact that there is space in the bottom of the Aurora Z4 aurora, so the bottom is not provided with a tripod or a lifting hole, it needs to be connected to the adapter plate to fix, and the standard also contains the Sarah adapter. plate. In addition, the adapter plate can also access the official accessories of the meters: table brackets, hangers and universal headrests and other special brackets (need to purchase separately).

The combination of the sliding lens cover and the power switch has become a unique label for Ramimi screenless TVs. This design combines lens protection with dust protection. It also allows users to open the door in a fresh and direct way. Extremely Z4 Aurora. In the actual experience, the process of sliding the lens cover does not feel so smooth, and at this point the pole meter still needs to make some small adjustments. In addition, it is recommended to add the function of the remote control dust cover sliding switch machine, because when the user uses the Z4 aurora and the lifting position is high, it is inconvenient to manually slide the lens cover. Switch lens cover combo
Sliding lens cap provides both lens protection and dust protection
The quality of the lens is the most direct factor affecting the screen effect of the projector. The Z4 Aurora Aurora uses a high-transmission coating lens, and the brightness of the stream reaches an international standard of 600 ANSI. It is the highest brightness of all the projection products of the current meter. . The light source adopts the German OSRAM LED light source with no radiation and eye-popping features. The parameters given by the official show that the service life is nearly 30,000 hours. If used according to the daily use for 10 hours, the polar meter Z4 Aurora can be used safely for nearly ten years. At the same time, the polar meter Z4 Aurora has a projection screen resolution of 1,280,800, supporting 4K Ultra HD video resources and a maximum screen size of up to 300 inches.

When the camera is turned on, the lens slide is closed, and the Z4 Aurora is turned into a Wi-Fi stereo. Like the popular smart cloud sound system on the market, it can directly play songs directly through the Internet. In addition, the gesture control is another highlight of the Z4 Aurora. With the addition of the gesture operation, the Z4 Aurora in the Wi-Fi audio mode has good entertainment, but what about the sound quality? Wi-Fi cloud audio settings
Due to the limitation of hardware, the sound quality of traditional projectors is really flawed. Compared with TVs, they are a lot worse, so many users have doubts about the sound quality of such a Wi-Fi cloud audio model. This is also a normal state, and many people will worry about the sound effects of the Wi-Fi sound mode. Harman/kardon sound system
As a product paired with TV, the Z4 Aurora without screen TV doesn't want to lose to the opponent in hardware, but it takes enough effort to put the audio in and out, and is equipped with a professional-grade Harman/kardon sound system, plus a Z4 Aurora's internal two-channel stereo speakers, whether used for listening to music or for watching movies, are capable of performing sound effects in a perfect way. It is no exaggeration to say that such an audio configuration of the Z4 Aurora is beyond the reach of most smart audio and smart TVs. Positive speaker hole distribution 1

The cooling holes next to the interface area are designed with diagonal bars and the internal heat sinks are clearly visible. Z4 Aurora Polaris has an automatic speed control (10-speed) fan, which can effectively eliminate the heat inside the fuselage and keep the host working stability. In addition, the pole Z4 auroral noise control is also very good, the amount of noise emitted during normal work is much smaller than the ordinary projector, in an acceptable range.

Turn on the turntable at the bottom of the Aurora Z4 Aurora and you will find there is a hard disk drive inside it that can fit into a 2.5-inch hard drive. Although the Polar Z4 Aurora comes with 16GB of high-speed flash memory, for some users who like to collect movies, this capacity is obviously not enough, so access to large-capacity hard drives is still quite practical for this part of the user community. It should be reminded that it is best to install a solid state drive in the hard disk drive. In addition to the fast storage speed, the most important is the position of the disk drive near the fan. When the host computer is working, it will produce high-frequency vibration. The mechanical hard disk has poor shock resistance. It may cause data loss. The bottom of the fuselage

To achieve a near-perfect picture, focusing is the first step. The Z4 Aurora uses an electric focusing method. Compared to the low-end projection manual focusing, the focusing speed and accuracy are much higher. In addition, there is a focus at the bottom of the remote control of the Z4 Aurora Polaris. After adjusting to this level, you can use the volume keys on the remote control to manually adjust the focus. GMUI main interface + manual focusing screen
Irregular projection screens are a problem most projection users will encounter, so trapezoidal correction is a very important function for projectors. However, the left and right trapezoidal correction often occurs on the 10,000-thousand-thousand-thick projector because of the high cost. However, the Z4 Aurora without a screen TV with a price of 3799 also has such a function. The user can change the screen according to the distortion of the screen. The angle is the base point to freely adjust the picture. Even if the polar Z4 aurora is placed on the bevel, the picture of Founder can be manually adjusted by the left and right trapezoidal correction. Left and right keystone correction
If you can't confirm whether the focus is correct or if the picture needs to be corrected, you can call up this polar meters without screen TV focus reference picture to assist in adjusting the picture to get the best display effect. Polar meters without screen TV focus reference map
The Z4 Aurora Aurora uses projection technology from Texas Instruments DLP optical projection technology and a number of picture quality enhancement techniques and color enhancement technology, plus the 600600ANSI brightness of the stream makes the Z4 Aurora Aurora both during the day and night, audio and video playback The text display has a good performance.

From the above real shot projection effect we can easily see that the gorgeous technical parameters introduced in the previous article is not just decoration, the screen of the polar meter Z4 Aurora projection is very uniform from the picture quality color to the brightness, the picture is clear and delicate, the picture reproduction ability is still can. The shocking viewing effect of the 100-inch screen is beyond the reach of ordinary TV. The projection effect of the camera lens has a certain deviation, the actual effect is much better than the photo. Extremely Z4 Aurora overall appearance
3D technology has conquered many fans with its unparalleled presence. The emergence of IMAX has also led many people to choose the most fundamental reason for going to a movie theater. But with the Z4 Aurora, you can experience the immersive feel of 3D movies at home. Of course, to see the 3D blockbusters first need a pair of 3D glasses, the previous article mentioned that the Z4 Aurora Polaris comes with two 3D shutter glasses, you can use the USB cable for charging life, the frame and the nose pads are of moderate hardness, wear It's more comfortable to go up.

If there is no film source, 3D glasses is a device, and 3D film sources are not easy to find is also a lot of well-known things. For the time being, we will not consider how many 3D video resources are available for the Z4 Aurora, because the Z4 Aurora Polaris uses another, more dependable way to provide 3D sources – 2D to 3D. To put it simply, any 2D video played on the Z4 Aurora (with or without web feeds and external sources) can be converted to 3D movies, not just movies, TV shows, concerts, ball games, news and even their own Shooting small videos can be as much as you want to show 3D visual effects.

Since the development of consumer electronics products, the human-computer interaction has undergone very intuitive changes. From keystrokes to touch, and from voice to somatosensory, human-computer interaction has refreshed our knowledge time and time again. It can be said that smart devices in the future. Whether or not it is successful depends largely on whether it can provide users with an intuitive and convenient way of interaction, so that a good "communication" between smart devices and users. Whether you are accustomed to keystrokes, touch, voice, or somatosensory operations, the Z4 Aurora can satisfy you, and it is very comprehensive in terms of interactivity. Extremely Z4 Aurora overall appearance display
After the experience, if you want to use a word to describe the product of Z4 Aurora, a screenless TV, it is undoubtedly "subversive." “Pretend to be a vinyl phonograph projector†completely overturns the image of the projector and refreshes the knowledge of the projector on the operating mode, viewing effects, and product details. Although such “non-screen TVs†cannot completely replace TVs in some respects, as long as TIMI Technology is able to fight in this direction without hesitation, it is believed that TIMI can create truly screenless TVs like TVs. Like the vinyl record player, it subverted people's lives and became a non-replicable classic.
