After the Z4Air was launched in 2015, the pole rice became very popular. Although there were some minor flaws, it was still sold out. The experience report that came out today is not an old version, but a new product that comes out of a New word: New Z4Air. Compared to the previous version, Mami brought some upgrades and also thrown another heavyweight in the field of “portable projectorsâ€. 
Smart TV/box information can focus on smart TV information network sofa butler (http://), China's influential TV box and smart TV website, providing information, communication, TV boxes, smart TVs, smart TV software, etc. Answering questions.
Out of the box
New Z4Air packaging is still similar to the old models, but unlike the previous "three-stage", the external hard anti-squeeze protection box has only two sections, of course, the total area and volume are basically the same.
Open the protective packaging thick to see this pale golden box, the words inside are more interesting, for the interpretation of the New Z4Air positioning, there are indeed many "evolution."
Open the thin paper can see the body of the fuselage. There is a factory film on the fuselage, which clearly shows the indicator light "mobile power switch" (yes, this screenless TV can even act as a mobile power supply) and switch mode.
The accessories are still almost the same as the previous generation, but the HDMI cable is independent from the package and is not in the package. You will see it the first time you unpack the express package, and don’t think it’s an extra gift.
With a 45-watt charger, when you see 19V, try plugging in the new Z4Air with your laptop charger and you can also charge it. (The laptop charger is 150 watts, but the voltage is also 19V. If the power IC does not do the current limitation theoretically, it can achieve high voltage and constant current charging. By considering the safety issue, I don't recommend that you try this way.)
The remote control is more sexy than the previous generation. From the previous plastic to the all-aluminum alloy, no matter if it is the perception or the feel of the hand, it will not be a little bit less.
Key layout is also more concise, removing the "screenshot" button of previous generation products, retaining the main common keys (the menu keys need to adapt to a period of time), and the oblique volume keys highlight the sense of science and technology. The Fn (Function) slide button and the charging port are at the bottom, there is not much pressure on the operation, and one hand can fulfill most of the requirements.
The exquisite remote control also has a factory film on the back, and tear off after reading. The main functions and upgrade points that can be achieved will be listed later.
Let's take a look at the upgrades brought by the host this time. There hasn't been much change in appearance, and all of them have been improved in details.
As a representative of the ultra-portable portable screenless TV, the New Z4Air still supports disconnected wire operation and built-in 13600 mAh battery from LG. Overall maintained the first generation of simple and lightweight profile, it is understood that its body alloy processing technology and Apple's MacBook Pro remains the same. It is worth noting that there is more than one camera on the left side of the fuselage, and the long-awaited "autofocus" function has been added.
The switch is still sliding, convenient and convenient, but also can better protect the security of the camera when not in use.
The more compact and delicate things, the more attention needs to be paid to the heat dissipation capacity. There is enough cooling space on the side of the fuselage to allow the machine to dissipate heat. The rotation of the blades inside during use will not substantially affect our view. (In general, you need to be within 5cm of the space to hear the fan sound.)
Back space has been marked, two USB port compatibility is good, you can directly access U disk, mobile hard disk, keyboard, mouse, and even wireless mouse and other peripherals, HDMI and the role of the headset hole is not much to say, on the map The right-most "mobile power" button allows the New Z4Air to become a "charging treasure," powering devices such as mobile phones or tablets via two USB ports.
The hole in the back of the camera is a speaker. As a portable, non-screen TV with a built-in sound source, the requirement for it is nothing more than "listen to the ring." The playing level is basically the same as the average laptop. If you want good surround sound or other higher requirements, you need to buy some of your own headphones.
With a body thickness of 23.5mm and a weight of 0.66kg, it can be easily grasped with one hand and it is not a problem to carry it with you. (The New Z4 Air does not give a bag or a carrying case. It should be carried as far as possible in the anti-collapsing backpack sandwich).
Connection related
Similar to the previous generation, the New Z4Air supports its own connection to WiFi, its own hotspots, and excellent Bluetooth 4.0 support. Of course, the compatibility between Miracast and Apple's AirPlay (screen mirroring) is also provided. It only requires the New Z4Air and the mobile phone to be in the same WiFi, so that the screen can be shot.
Of course, if you accidentally appear to be incompatible with the device, you can also bind it by downloading the phone assistant. (Search for "very meters" in major APP markets. The above figure prevents the platform from overexamining and coding.)
The iPhone is relatively simple, just need to call out to slide out the "control center" on the desktop, click on the "screen image" to search for devices that currently support screencasting.
After connecting to play the video, Apple will appear above the screen, this time you can press the Home button to go back to the desktop to operate other APP, the movie still continues to play on the new Z4Air. (If you want to fast-forward video, you also need to click the blank area in the interface above to call the progress bar to adjust. To exit the screen, click "Exit Connection".)
Powerful remote control
As mentioned above, there are many upgrade points for the remote control. The highlights will be listed one by one so that everyone can understand the main functions of the remote control. The New Z4Air remote control supports voice and gravity sensing through the factory back cover of the remote control. , flying mouse, laser pen several functions. The remote controller and the host computer are connected via Bluetooth, avoiding the inconvenience that the infrared signal must be transmitted to the machine, as long as the Bluetooth signal coverage can be freely operated.
Let's talk about the "voice" function. With the deep cooperation between Miji and Xunfei, XFei voice is built into the system of meters. Just click the "Voice" button at the top of the remote controller to call out the voice control function. Not only can you sing songs, search videos, but also watch stocks, check the weather, jokes, and so on. Currently, besides Putonghua, Cantonese and Sichuan dialects are supported. In addition to Putonghua, other languages ​​are still in beta (beta), and the ability to understand the language remains to be improved. Of course, the Mandarin version can basically meet daily needs.
It is not new to use the remote control to play games. You can run a lot of interesting game applications by installing the three-party app through the built-in GMUI (Android based) system. If you have a supportive application, you can also use the remote control (the built-in gravity sensor on the remote) to make it more fun to play.
If you are an old rice user, you should be familiar with the "squirrel". After being tired of the buttons, the left and right buttons can't be similar to the computer. "Where do you want to, where is it?" People, by the mouse in the air will appear to slide the corresponding pointer, OK key is OK, more convenient. (Turn on the squirrel and shake the remote control with Fn off.)
Of course, considering that part of the portability will be designed to business users, Kamitsu not only sets up an “office mode†in the system alone, but also it can turn a brand new remote controller into a “red laser transmitter†— when the bottom of the remote controller is at the bottom After the Fn is turned on, pressing the "Menu key" will directly call out this function. The red light spot on the left side of the above figure appears.
display effect
The most basic function of smart projection lies in the display. New Z4Air has a 20% increase in brightness compared to the previous generation. The brightness of 300 ANSI lumens allows users to easily watch in general indoor light. Of course, the best effect still requires a dark room. reflect. (Constrained by the volume, it's good to be able to do this level)
Of course, when the light is sufficient during the day, it is still somewhat reluctant to cast the wall directly, and the curtain effect is much better and can be seen during the day.
At the same time, the new meter Z4Air supports automatic trapezoidal correction, pro-test is good. It is worth noting that trapezoidal calibration is turned off by default. It requires the user to work after the system is turned on. At present, it can automatically correct the trapezoidal shape caused by the up and down tilt, that is, it has a vertical trapezoidal correction function.
Adding a lot of auto-focus after worrying a lot, will automatically focus once after boot, if you move the body during use, will automatically focus again. Of course, manual zooming can also be done by yourself. Simply turn on Fn at the bottom of the remote control, and press the “plus†and “minus†keys to adjust the focus manually.
It is worth mentioning that, unlike the traditional diamond pixel architecture, the New Z4Air uses a new TRP square pixel architecture that can greatly reduce the jagged edges of the projected images. This is also the comparison of most of the same 720P resolution products. New Z4Air seems to be More "fine" secrets.
The projection ratio of 1.07:1 enables the New Z4Air to focus successfully and project successfully in very short distances. The original compact projection projector can easily face more diverse scenes.
Thanks to the powerful computing power of the Mstar 6A628 Cortex-A7 and the graphic rendering capabilities of the Mali-450MP2, there are few problems with the dynamic display, and high-definition movies will not appear to be smeared or dropped. The 0.3" DMD RGB-LED display chip is already very conscience in the same positioning of the smart projection, fully competent for daily home entertainment or small conference room report, search in the market for portable positioning of the smart projection, the very Mi New Z4Air is undoubtedly the current price The most worthy of existence in the selection.
