Public test king once released a new meter of H1, but he didn't pull me in, so he bought the Z4 Air, and he gave his wife office work. At home, he could also watch movies and TV series. Originally wanted to start with the Z4X, the built-in Harman Kardon's speakers will sound better, but they're bulky and still require the office work of their wives.
As of the time of the press release, the meter H1 has been released by the public test report. Please refer to the article on value-friendship swq01 and enjoy watching Z4Air continuously.
Sound quality and perception resonate - objective evaluation Kimi H1 without screen TV
A nonsense article
What is "No Screen TV"?
Personally think that is a publicity gimmick, in fact, projector + TV box + speaker integration of a product, this idea is good, thanks to projector technology innovation, to solve the traditional projector itself volume and life problems, but also to solve The use of the need to connect the video source and the speaker trouble, to get online to watch online video resources and other functions, which greatly meet the ordinary people's daily needs. As far as I'm concerned, the living room still uses an LCD TV. In the bedroom, you use this one. There is exactly one wall. Evening in the bedroom is very cool.
Two old rules: Unpacking articles
The packaging is much bigger than you think... It's a square box
Then it is like this, divided into two parts
Look at the box on the left, according to the graphical identification, it is clear that the power adapter and remote control
Comes with HDMI cable. For me, I think that any HDMI cable that comes with this type of product is a conscience manufacturer.
Look at the right box, the projector body...
A simple quick fit guide and a one-year membership card for Mango TV catch the eye... Value of 360 Soft Girl Paper
The reverse side of the card is a description of the key functions of the remote control and an introduction to the projector interface.
Side vents, next to a focus key
The rear row of commonly used interfaces: USB2.0, USB3.0, HDMI, 3.5MM audio interface, there is a mobile power button, forget the box is still a 13600 mAh mobile power
The official statement, can be full of iphone 4 times or iPad mini 2 times .... well enough...
The lens cover has a sliding type, and the surface is made of a drawing process....
Slide it on, and the newly arrived machine has more than enough power.
Three use articles
Put Z4Air, turn on, adjust the focus (focusing slightly more damping), the first feeling is a big ah ... because the distance from the wall is close, plus Z4Air itself without optical zoom, so you can not zoom the size of the projection ( Traditional projectors should be scalable.) The official nominal throw ratio is 1.2:1, (in the 2M position is 76 inches), Z4Air can only do vertical trapezoidal correction (plus or minus 40 degrees). H1 and Z4 aurora can be trapezoidal correction. Personally think that left and right trapezoidal correction is more useful, this can be placed in the bedroom bedside cabinet or drawers and projection wall surface position to the left or right, the screen automatically correct deformation. Because Z4Air does not have a left-right trapezoidal correction, it can only be placed right behind the wall vertical, otherwise the projected image will be deformed and cannot be corrected.
Then, the system updates to the latest version of the firmware, the system stores 8G, internal storage 8G, 1G memory, custom GMUI system based on Android 4.4.2, the official parameters did not write the CPU model, just said 1GHz quad-core, GPU is stated to be Mali- 450MP2.
The system UI interface is a typical TV box interface, the operation does not need to say more, the following talk about a few key features
1) The massive video resources in the Mango TV app, the WeChat scan code to log in to the linked account, and then enter the number of the sent member card, you can enjoy one year's VIP membership services, and send 4 coupons every month to filter ads. Wait.
2) Screencast
iOS and Android devices can be used for screencasting. For example, iOS devices connect directly to the same WiFi network. Then you can draw out a menu, click Airplay (pictured), and then open the mirroring function. Click Finish to complete. The screen image is displayed.
Mirror the entire mobile phone operation interface to project to the wall, of course, play games can also be projected.
The following is a video presentation. You can see that while the screen is being projected, audio cannot be transmitted wirelessly. You can only use the speaker of your phone to listen to the sound or pick up your own headphones. Since my phone is muted, the video is silent throughout.
The quality of the screencast is still good, almost no delay, to do mobile phone function demonstration, or to play the mobile game on the big screen feels pretty cool (my wife actually cast screen to play candy crush, I was drunk), tested the WiFi connection to 5G will stabilize the high-speed point, 2.5G may be card. In addition, a mobile app can also be downloaded on the mobile phone, and video projection playback can be selected from the mobile phone through the app.
3) Projection display effect
Z4Air official parameters are as follows
It is worth noting that the resolution is 720P, compatible resolution 1080P/2K, refers to support 1080p and 2K high-definition video files, that is, regardless of the video source is more clear, the highest projection resolution is 720P, 4K resolution did not write , It is estimated that the camera does not move ... In this way, it is also reasonable, Z4Air's positioning is still office-based. Place a projection effect demo shot with iPhone 6 below for reference.
Because hand-held mobile phone shooting, plus Youku on the video compression, the actual viewing effect is better than the video some, although the highest projection only 720P, but it can fully meet the needs of ordinary users viewing. For users who do not need to take care of the office, you can choose the Z4X or Z4 Aurora, the local tyrants can choose H1
4) Document Presentation Function
GMUI has a built-in WPS OFFICE document presentation function in the full range of products. Inserting a USB flash drive can read excel, word, and ppt format documents for office demonstrations. Overall, it is still good, but some minor problems are encountered in actual use. It should be WPS OFFICE itself compatibility issues. I used the PC's OFFICE 365 template to generate 3 files in docx, xlsx, and pptx formats.
Open the main interface, select the local directory, then plug in the USB flash drive, select the memory card
U disk in the list of documents, please ignore these titles
Test EXCEL file, read no problem, the remote can only move one by one cell, do not know how to switch "table 1" to "table 2", but the problem is not large, the general presentation function to OK 
After the WORD document file is opened, there are only pictures, and the text on the picture is missing. This should be a compatibility issue.... Maybe the file format I use is too new. WPS OFFICE is not yet fully supported...
For an old WORD file format, it would be nice, but if you encounter the form in WORD, when you turn down the page, it will get stuck. Move the cursor to the bottom right end of the form and press the remote control. "Down" button to continue to page down.
PPT file, this should be the most needed file, But! The template encountered was fancy and stuck, even flashback... I don't know if it was a case... 
5) Others
Trying to install VST on USB failed. USB stick connected to the projector, Android apk format files are automatically hidden, but not surprising, the specific reason you brainstorm, Fortunately, Mango TV members are also cheap, 300 members a year, less than 1 dollar a day , we all support genuine
Four summary
Extreme Z4Air as a business-oriented projector is generally good, compact size, easy to carry, 13600 mAh charging treasure, suitable for people on a frequent business trip, but used to do home theater, it is best to choose Z4X The above product oh :)
