I have been exposed to projection since the beginning of my work, but at that time the projection was used for business purposes, so I connected my laptop to demonstrate PPT or other documents, and the price was often tens of thousands, which was not affordable for my class. Since I noticed that there are also micro investment products in the projection market last year, and the price is only about 3000, I finally got a Jimi Z3, and experienced the feeling of a large screen home theater. This summer, we finally arrived at three new upgraded products released by Geemi Technology: Z4X, Z4 Air and Mango Xiaomi. They are aimed at different groups. Mango Xiaomi is a fashionable youth group. Today, I will tell you how this product performs through my own experience.

Appearance design & details

The first few appearance pictures show that the product does not seem to be as amazing as expected, nor is it the color that young people like. In fact, Mango Xiaomi has five bright colors to choose from: candy green, crystal blue, macaroni powder, dawn yellow, and obsidian black. When I get it, it is just black, which is relatively low-key. When I see other colors, I think it is "the micro investment with the highest appearance value".

The shell of mango moustache is made of frosted material, which has good friction and is easy to carry out and not easy to slide off, but the disadvantage is that it is easy to get dusty and not easy to clean.

Of course, with the appearance design of "lighter and thinner", we can still realize that the 111.5 × 211 × 25mm size is slightly larger than the 6-inch screen mobile phone, and it can indeed be put into a satchel. The overall weight is 0.62kg, which is light to carry outside.

Mango Xiaomi adopts a sliding switch design, integrating the lens cover and power switch, which solves the headache problem that the Z3 split lens cover often cannot find. The metal baffle, coupled with thread processing, has just the right strength for sliding and springback. The lens will start automatically when it is opened, which is very convenient. However, during use, I found that if I shut down the machine by remote control and forgot to close the sliding switch, the machine body would always consume power.

There are cooling holes in the front and side of the fuselage, and a temperature control system that can automatically adjust the wind speed according to the temperature is hidden in the grille in the front. In order to improve the heat dissipation effect and reduce the noise when the machine is working, Mango Xiaomi has covered the inner wall of the shell with graphene, a nano material with ultra-high thermal conductivity. The efficient self heat dissipation can reduce the workload of the internal fan.

There is a focusing wheel on the side of the fuselage, which can focus manually. The damping of the wheel is somewhat dry and not very flexible. It needs to be adjusted slowly. It is a pity that there is no auto focusing function.

There are a series of interfaces on the back of the fuselage, including one HDMI, one USB2.0 and one 3.0, and one headphone jack. There are not many interfaces, but they can meet daily use.

The mobile power mode switch is beside the headphone jack because Mango Built in one 10400mAh Lithium battery, which can play for two and a half hours continuously when not connected to power, is used as mobile power. The square hole array beside is a loudspeaker, Mango The sound effect of is much better than that of the Z3. Although it is not comparable to professional audio, it can also meet daily use. If you want better results, you can also connect an external power amplifier or use Bluetooth audio.

Mango Xiaomi fuselage There is only a nameplate in the middle at the bottom of the. It is flat. There is no screw hole for the tripod that we are most concerned about. I don't know how to think about it this time. There is no screw hole for the three products. It's good that the Jimi Z4X comes with an adapter bracket, Mango Xiaomihe The Z4 Air can only be placed horizontally, which is really inconvenient to use. You can only use books or other items to constantly adjust it.

The Bluetooth remote control is very simple. Although there are few keys, it can meet common functions, especially the screen capture key and image mode key. It is very practical and can easily capture a screen without using other software.

The power adapter imitates the style of Apple laptop and can be easily stored.

performance & to configure

Mango It is equipped with a high transmittance coated lens, whose brightness reaches 250ANSI lumens, 5000:1 contrast, standard resolution is 1280 * 720, and LED light source can be used for 30000 hours,.

Mango The projection ratio is 1.2:1. If you want to put a 100 inch screen, the actual distance is about 2.5 meters. Since it cannot be supported by a tripod, you can only put it on a table for testing.

But just because of its portability, it has a built-in battery, which can be placed in every corner of the family. The study can replace the monitor. Dining in the restaurant can also be fun, and even cooking in the kitchen can also be fun. We can see that the image is bright and bright in strong light without dark light, and the screen less TV can not replace the ordinary TV in the daytime.

UI Interface&Application

Jimi has a customized UI - GMUI. The first interface is very simple. There are video, music, games, applications, settings and other modules. On the top right is the status bar, which displays network status, power, weather and other information.

Mango It adopts 4-core 1GHz CPU, Mali-450MP2 GPU, 1GB DDR3 memory, and 8GB built-in storage. This configuration has been highly configured in similar products.

Mango Xiaomi's connection to receive network signals is relatively smooth. I connect to the route about 5 meters away from a wall. The speed measurement is still ideal.

There are many methods for correction in projection settings. The most practical one is trapezoidal correction, which can be set automatically or manually, because we cannot place the projection horizontally with the screen, which is often used in ordinary times. In general settings, we can also set screen saver, startup source, theme, etc.

With the combination of Jimi Technology and Mango Media, Mango VIP has provided nearly 3000 movies and more than 100000 TV series. The music module uses Baidu Music, which also has a lot of resources. We can download APP for other things such as games and applications.

Jimi Assistant&Experience

▲ Jimi has also developed a special mobile APP for projection - Jimi assistant, which is rare in other projections. The Kimi assistant can have more powerful functions than the remote control. As long as the mobile phone is connected to the projection quickly under the same WiFi.

▲ The Jimi assistant has functions such as remote control, on screen display, application management, mobile phone resources and cloud screen saver. It is more convenient to use a mobile phone as a remote control. The function keys are similar to the remote control. It also has functions such as voice, keyboard, touch pad, etc., which can control projection in multiple ways. Jimi's cloud service is also good. As long as you have a Jimi account, you can set a cloud screensaver, and the projection configuration can also be stored in the cloud. It can not only replace the remote control for control, but also realize the two-way same screen between the mobile phone and the projection. Resources in the mobile phone, such as pictures, videos and common documents, can be directly pushed to the projection screen through the APP, which is very helpful for mobile office.

Performance&Testing

Color test is to investigate the color restoration ability of projection, whether it can restore color accurately, whether there is color deviation, and whether the color transition is smooth and natural. Mango Xiaomi has adopted 11 colorful enhancement technologies, and the overall color performance is relatively high, with slight color deviation.

In the light and shade test, the gradual transition of each color difference is relatively natural, and basically all can be clearly displayed, only the dark part has some blurry edges.

Due to the small size of Mango Xiaomi, the sound effect and volume of the built-in speaker can not perform well. Finally, it needs to be solved by external audio. We can connect the audio through cable or Bluetooth.

After two hours of startup, The highest temperature of Mango Xiaomi's body rose by 13 degrees, and the power adapter's temperature rose by 30 degrees. The body has good heat dissipation, and the power adapter's heat is too high.

Scene experience&effect

Mango Xiaomi adopts TRP architecture, and the pixels are optimized from rhombus to rectangle, which has good performance in image aliasing and delicacy. I have selected films in different formats, and the common formats are basically supported. The film plays smoothly, the picture is clear, and the sense of hierarchy is also in place.

Realistic pictures are generally satisfactory, with clear layers and bright and natural pictures. Mango Xiaomi adopts 16 image quality enhancement technologies, which can capture the "dark area" and "bright area" of the image frame by frame, intelligently adjust the brightness, and make the picture more vivid.

Generally, we can only experience 3D movies in cinemas, but we can also enjoy 3D at home with the extremely meters of 3D active shutter glasses.

Mango Xiaomi adopts active shutter 3D imaging technology, which is brighter and more stereoscopic than ordinary dual polarized 3D cinema. It can play 3D movie sources such as left and right format, top and bottom format, and automatically synthesize 3D effects. The system also has its own 2D to 3D function, which gives us more options.

The game screen plays smoothly without delay. If it is equipped with a chicken handle, it can be easily accessed because it supports 2.4GHz. It is also a great enjoyment to play large screen games.

Mango Xiaomi, as a portable micro investment, is indispensable for office use. The PDF and PPT documents in the above figure can be displayed directly without access to a computer. The handwriting is clear and legible.

  Because the screen shot is greatly affected by the light and environment, it cannot really reflect the actual effect. Let's take a look at the video I recorded:

Summary&Suggestions

With a variety of beautiful colors to choose from, the Kimi Mango Xiaomi non screen super TV can clearly put on a hundred inch screen. It is lightweight and small, suitable for carrying around, targeting young people. It is a youth style of fashion and entertainment, and worthy of young people's support.

Some suggestions:

▲ The product lacks support For screw holes, it is recommended that Jimi launch a special tray as soon as possible to facilitate the connection of the tripod.

▲ If the sliding switch is forgotten to close after shutdown, it will continue to consume power. It is recommended to remind on the shutdown page.

▲ Manual focusing is troublesome. It is recommended to add auto focusing function.
