XGIMI Z4 Air smart micro-projector review: a great sharing tool you can carry with you
|
Smart micro projectors, to some extent, are a substitute for televisions and are loved by more and more young people because of their small size and portability. I believe that friends who are interested in micro-projection products must be familiar with XGIMI. In the first quarter of this year, XGIMI seized the largest share of the domestic home projection market with a market share of 49%. At the end of June, it released three new products, among which XGIMI Z4Air is known as the thinnest projector in the history of high-definition micro-projection. The product is currently in the pre-sale stage and is expected to be available for sale this month. If you want to know whether this is a device worth buying, follow Xiaodiandian to experience it.[Unboxing] It is said that this is an era of "looking at the face", and hardware products are no exception, especially when they are labeled with the word "smart". First of all, in terms of outer packaging, the XGIMI Z4Air abandons the "cap" design commonly used in various smart devices today, and adopts a new mode that can be opened horizontally. On the side are some parameters related to the device. Xiaodiandian got a champagne gold machine this time. In addition, judging from the two partners, Mango TV and Baidu Music, XGIMI has begun to focus on content. From the experience point of view, unlike this "laborious" design, the Z4Air packaging is easier to disassemble. As long as the packaging box is unfolded horizontally step by step, we can see all the accessories inside. From left to right are the remote control, button battery, charger, HDMI cable, projector and instruction manual. [Body Design] Now, let us welcome our protagonist. The overall design of Z4 Air is simple and elegant, and the metal shell is very textured. The sliding lens cover on the side can directly control the machine switch, which is easy to operate. The side closest to the lens is the focus wheel. After adjusting the distance between the body and the display screen according to the required image size, you can turn the focus wheel to adjust the clarity of the image. There are some sockets on the back side of the body, from left to right they are power jack, USB2.0, USB3.0, HDMI, headphone jack, mobile power switch. It should be pointed out that the projector itself can only be charged with the charger that comes with it; turn on the mobile power switch, you can use Z4 Air to charge your mobile device, which is equivalent to turning it into a "power bank". The body has a built-in LG13600mAh rechargeable battery, which is enough to cope with emergencies such as the phone running out of power when you are out. Press the power switch to check the remaining power of the device. When the power is less than 50%, the LED light on the corner will turn red, otherwise it will turn green. The picture shows the charging status. At first, the red light is always on. So the question is, how can you determine whether the device is fully charged without turning it on? The four corners are all designed with arcs, and this humanized detail also reveals the portable positioning of Z4Air. Because unlike fixed devices in office settings, portable devices will come into contact with users more frequently, so the chance of bumping will also increase. Compared with the Z4X released at the same time, the Z4Air has obvious advantages in width and thickness. The actual body thickness is 23.5mm, which is nearly 40% thinner than the previous generation. The weight is 0.65Kg, and the surface size is comparable to that of iPad mini. 【Screen Effect】 The XGIMI Z4 Air uses DLP projection technology, with a projection ratio of 1:2.1, a nominal brightness of 250 lumens, a contrast ratio of 5000:1, a resolution of 1280×720, and is compatible with 1080p and 2K, but does not support 4K content. According to actual tests, if the focal length is adjusted to the shortest, the distance between the device and the screen needs to be at least 12cm to achieve a clear picture effect. As this distance increases, the length and width of the picture also increase, basically changing linearly. If you want to achieve an 80-inch display effect, this distance needs to be more than two meters. At the same time, the screen brightness decreases as the distance between the device and the screen increases. However, the brightness does not change significantly with the power level. When the power drops to 20%, a prompt will pop up on the screen, but the screen brightness does not drop significantly. It should be pointed out that the battery life is nominally two and a half hours. According to actual tests, it is no problem to watch a 100-minute+ episode of "Where Are We Going, Dad" with 80% remaining power. Raise one side of the device to see how well the Z4 Air handles distortion. This is what the device looks like when it is lying flat. By comparison, we can find that the distortion of the picture is not particularly obvious and is within an acceptable range. 【Application & Content】 You can download XGIMI Assistant from the App Store. After installation and connection, you can use the remote control function to directly control the projector with your phone. It also supports the same-screen display of different devices such as PC, Mac, Android and iPhone. In terms of synchronization speed, it takes about 10 seconds to display a 3M picture during this test. Of course, this is also related to the speed of the LAN itself. It can be seen that the system shows that the actual memory is 7.8G. It should also be pointed out that the projector can directly identify the inserted storage device and read related documents. The built-in WPS can also provide convenient support for commonly used business files, such as PPT, EXCEL, WORD, PDF, TXT and other formats. It must be said that this is much simpler than the traditional way of copying the document to the presentation computer first, and then connecting the computer to the projector via a VGA cable for sharing. The document display effect is clear, and the remote control is especially suitable for PPT presentation and playback. In addition, according to XGIMI CEO Zhong Bo, a new application that supports wireless sharing of screen with computer will be launched soon. With this function, the lack of VGA port on the projector will no longer be a problem. Mango TV is built in, and it can play smoothly after connecting to the Internet. Netizens who have used the previous product of XGIMI may be worried about the fan noise of the product. After testing, this problem has been significantly improved on Z4 Air, and the sound is clear. Of course, if you don't want to disturb others, you can also plug in headphones. The last point to mention is that Z4 Air also supports 3D effects. The system provides multiple 3D modes including left-right 3D, top-bottom 3D, and Blu-ray 3D. You can switch by pressing the 3D button on the remote control. [Summary] In general, Z4 Air has a simple and stylish design, clear picture effects, and practical functions. It is quite cool to take it out for business presentations or friends' gatherings. Of course, the premise of "being presentable" is that you can "take it out". The compact and lightweight body of Z4 Air can meet this premise. The 2.5-hour battery life can also meet the basic needs of watching movies and giving speeches. The only drawback is that the delay of the same-screen display needs to be further optimized. The current pre-sale price is 2,499 yuan, which is moderately priced among similar products. Therefore, for friends who are planning to buy micro-projectors recently, Z4 Air is a choice worth considering. As a winner of Toutiao's Qingyun Plan and Baijiahao's Bai+ Plan, the 2019 Baidu Digital Author of the Year, the Baijiahao's Most Popular Author in the Technology Field, the 2019 Sogou Technology and Culture Author, and the 2021 Baijiahao Quarterly Influential Creator, he has won many awards, including the 2013 Sohu Best Industry Media Person, the 2015 China New Media Entrepreneurship Competition Beijing Third Place, the 2015 Guangmang Experience Award, the 2015 China New Media Entrepreneurship Competition Finals Third Place, and the 2018 Baidu Dynamic Annual Powerful Celebrity. |
