Polar meter Z4x screenless super TV evaluation image quality beyond imagination

Smart micro-investment is making strides into the homes of ordinary people, and in recent years, Miji Technology has also been actively promoting innovation in the field of micro-investment. The recently-launched Jingmi Z4X non-screen super TV has just been successful On the market, the theme of this product is "update horizon, sound and picture quality beyond imagination", in addition to the basic projection features, it also allows you to enjoy large-scale movies, listen to music, play games without a word.


Extreme Z4X, whether it is appearance or philosophy, all hope to make breakthroughs on the basis of several previous products. First of all, it has been embodied in the design of the packaging. The minimalist style has been implemented to the end. The internal power cord and adapter are provided internally. , remote control, manuals, button batteries, each one, and the difference is that the manual made a card, but the usage is very detailed, of course, when the user first time you will see the system comes with Teaching process.




Design

The appearance of the ultra-thin Z4X non-screen super TV is very design. For the pure white body and the black “disc” shape, different people may have different understandings. Some people think that there is a disc player, but there are People think that this is a reference to the shape of a record player. In fact, no matter where the source of design inspiration is, this type of styling does seem to have a great affinity. Friendly reminder, this black “disc” cannot be turned, but it contains A touch-activated power button and a gesture recognition device can switch songs by waving them right and left above the “disc” when playing music.


The body size is 19919650mm and weighs about 1.2Kg. On the side of the front, you can see a lens hole that can be opened and closed. On the right is the Harman/Kardon Logo. On the back end you can see that the product is equipped with multiple interfaces, HDMI, USB 3.0, etc. , while the external sound is set at the bottom of the fuselage, the overall design is simple and practical without losing the beauty.



Basic parameters

After enjoying the appearance, you still have to go back to the hardware parameters that determine the height of the product. The Z4X non-screen super TV adopts Mstar quad-core 1.5GHz CPU, equipped with 2G DDR3 high-speed memory, 16G flash memory, and built-in top-level 4K TV chip. The whole power is 65-90W, and the GPU is Mail-450MP4. The system is based on Android 4.3. Build it. The Z4X adopts the S8 Opto-mechanical Engine. Its dual-optical path design has a brightness of ANSI 580 lumens. Although the perception is brighter than the commonly used 0.4S optical camera in the market, personally, there is still room for improvement in this brightness.



Z4X contrast ratio 5000:1, the standard resolution of 128,800, compatible with 1080P, 2K, 4K and other high-definition playback. Using ultra-high-precision electric focus, the focus can be easily achieved with the remote control, and the focusing effect is satisfactory. Each corner of the projection screen can be accurately and effectively focused, with no partial clearness and blurring of other parts.



Compared with the previous generation, the Z4X has more projection customization adjustments, and these functions have been further enhanced. The Z4X supports vertical ±40 degree trapezoidal correction. The projection method includes front projection, rear projection, and ceiling. Brightness, contrast, saturation, sharpness, color temperature, and three primary colors can all be adjusted.


Also rich in interface configuration, there is a standard 3.5mm audio output interface, 2 HDMI interfaces, 1 USB 3.0 (transmission rate up to 5Gbps), 1 USB 2.0, 1 headphone jack (with headphones / SPDIF Coaxial output design), a WLAN interface, an additional 2.5-inch HDD enclosure at the bottom, which means users can expand the built-in storage space by several hundred GB, the product supports Bluetooth 4.0, 2.4G/5G dual-band WiFi, and Provides a hotspot function, a young and old wireless Internet to watch movies, play games with the handle are no problem.



Interestingly, the Z4X also supports wind speed adjustment of the cooling fan, and an air inlet is added at the bottom of the product. Users can adjust the cooling intensity according to the different ambient temperature, but personally think that the "automatic" cooling function can be autonomous in many occasions. The heat regulation work is completed without the user's hands, and the noise can be controlled below 30 dB under normal conditions. From these basic parameters, the configuration of the Z4X is not only comprehensive, but the specifications are not too low, and daily home use is adequate.

Hands-on experience

After understanding the basic parameters, you must personally get started to know the quality of a product. The power-on response speed of the Z4X is still relatively fast. The menu interface is similar to the Metro style, and the layout is clear and reasonable. Movies, music, applications, and related settings are all clearly visible. Zimizi Z4X has reached a cooperation with Mango TV in terms of film and television resources. From the perspective of quantity, it is relatively complete. The update speed is also very timely. Major mainstream programs can be found here. Of course, it is best to watch live TV. Still an additional live APP is installed, and due to the copyright relationship, some large movies must be paid or registered for VIP to watch.



For online viewing, the user can select the 16:9 and 4:3 ratio of the screen and adjust the sharpness. However, because it is based on the Mango TV, the screen adjustment function of the device itself cannot be fully displayed. If you insert a U disk or an external storage device to watch your own video, you can achieve more adjustment functions. In addition to several screen sizes, you can also choose several picture color schemes, such as soft, standard, self, Definitions and more.


Speaking of the screen effect, it is reasonable to say that basic options such as brightness, contrast, saturation, etc. should be easily and intuitively adjustable. However, the Z4X does not directly call these options through the remote control during viewing. It must be “set”. After adjusting it, it will appear in the optional form in a customized form.

In terms of projection effects, compared to the Z3S, there is indeed an increase in brightness, smooth playback without smearing, sufficient clarity in a dark environment, and a high degree of color reproduction. Whether it is cast on a white wall or a projection screen, A good visual effect was achieved. Although the Harman/Kardon sound unit was equipped with a shock, the level of sound was already coming out. The overall situation was clear and transparent, and qualified students could choose an external sound system to enhance their listening performance. As for the viewing in a light-filled condition, it is obviously contrary to the original intention of the projection device. It is of course impossible to reach the effect of a TV set when the projector is turned on.




In terms of music playback, Zimi X4X has cooperated with Baidu Music, which can be categorized variously in terms of music classification. There is no need to worry about the quality and quantity of resources. If you want to listen to specific songs you can search on your own, there is no so-called song list. With the list, in addition to using the remote controller, you can also switch songs from side to side above the camera. However, due to gesture recognition, occasional misoperations may occur.


Since it is based on the Android system, then playing games on the Z4X is certainly possible. The “quick speed boat 2” with certain requirements for the equipment is also relatively smooth to play. As for other games and the use of the APP, there is basically no problem. In addition, Z4X and Bluetooth devices are of high quality and the response speed is fast within the valid range. As for Word and other office files Xiaobian try it, and can not be read directly, but the user can install the meter assistant to achieve the sharing and viewing of pictures, videos, document resources in the mobile device, and even can make the phone into a remote control , voice control, a key with the screen can be achieved.




In the end, Xiaobian did not forget to test the viewing effects of 3D and 4K movies. First, the product was equipped with a pair of active shutter 3D glasses. Z4X supports both left and right 3D formats, wearing glasses, and selecting the corresponding format conversion. You can enjoy 3D visual effects. Of course, you can also watch the 3D source provided by Mango TV. However, from the perspective of the quality of 3D source conversion, there is still a lack of recognition of the objects in the movie and the sense of layering. It feels a little dazzling, compared with the Z3S.



As for the 4K movies, it is indeed very clear. The playback can be completed easily without any pauses. With the Z4X up to a 300-inch giant screen projection, the 4K movie's shocking experience is even more profound. The only worry is that the 4K movie itself is large, so to get a smooth experience through online viewing (Mango TV), it must be equipped with a sufficiently powerful network environment. Individuals are more inclined to use U after downloading on a PC. Disk or mobile hard disk access to watch.




to sum up:

After a trial experience, I believe that everyone has a more specific understanding of the Z4X Super Screen TV. This product is stylishly designed to integrate with the home environment, CPU, memory, audio unit, storage, system architecture, Equipment compatibility and other configuration and parameters are very handy for family viewing entertainment. The definition of the word “No screen super TV” is also well understood. It is necessary to be able to meet the convenience of portability, but also to obtain TV boxes or smart TVs. Massive film, music, and entertainment game resources can be said to be a good combination of Z4X.
