The rapid development of projectors in the past two years is a bit surprising. The projectors that were once only available in cinemas or schools have gradually entered our lives, and various brands are also competing. There is a feeling that Wang Xietang and Qian Yan flew into the homes of ordinary people in the old days. Among many brands, the name of Jimi is very eye-catching, Whether in the Double 11 or 618, the sales volume of Jimi is always among the best. In March this year, Jimi Technology launched its first 1080P high-definition micro projection product, Jimi H1, leading the home projector to a new height.

TI, as an old buddy of Jimi Technology, has also taken the latest 1080P core DLP chip as the main control chip of H1. This time, the Jimi H1 has been upgraded not only in configuration, but also in appearance design, sound effect and other aspects. Here is a detailed evaluation experience.

First of all, let's look at the parameters. For the projector, the most concerned must be the brightness. The brightness of the polar meter H1 has reached 900ANSI (different from the lumen algorithm of the bulb machine), and the contrast has also reached 15000:1. It is the first intelligent micro projector supporting HD 1080P in China, more in line with the name of screen less TV. In addition to high resolution and high lumen, the Jimi H1 takes the four core processor of the Mstar 6A928 Cortex-A17 and the 3GB DDR3 RAM+16GB ROM. It can play 2K, 4K movies or 3D movies smoothly in this configuration. The large storage space also satisfies users who like to play large-scale games.

The line of sight switches to the appearance of the equipment. The main body of the Jimi H1 is made of an integrated magnesium aluminum alloy panel, which is densely meshed. The lens is in the upper left corner, which is larger in size than the products of previous generations of Jimi. From the perspective of volume, it seems that it is not suitable for being called micro investment, H1 is 120mm high, 200mm long and 200mm wide. It is similar to a cube and has heavy components. The projection lens is protected by a sliding cover. The music in the middle of the mesh has two sound outlines, which will be described in detail below.

On the back of H1, in addition to the lower interface, the most prominent one is the two rectangular vents. The metal backplane is designed as a shutter, which has a more obvious heat dissipation effect. It can be seen that the designer has fully considered the equipment performance when designing the appearance.

The integrated magnesium aluminum alloy panel is very grand from far to near. The nano injection molding process ensures the whole texture. The large hollowed out mesh can not only greatly help the heat dissipation of the equipment, but also cooperate with the sound, so that the entire equipment can show the best sound effect under the condition of ensuring stability.

The top is the control area. Next to the XGIMI is the Favourite key, the Up/Down Switch key, and the Play Pause key. Above the key is the highlighted bar volume touch bar. When the Jimi H1 turns into the audio, the operations such as cutting songs are more convenient and fast.

The slide cover of the Jimi H1 lens is still the same as that of the Jimi Z series. The switch and dust-proof slide cover are two in one design. In terms of brightness, H1 has reached 900ANSI lumens, which is equivalent to 3750 lumens of the traditional bulb machine, What is the concept of 900ANSI? In short, it can clearly present the picture when the lights are on in the living room. In addition, the 2073600 rectangular pixel architecture has brought a very delicate picture effect. The resolution has been improved to 1080P, 2.25 times higher than the original 720P product. It has undoubtedly become the top configuration in the industry. The Jimi H1 lens adopts the antireflection coating process, which is conducive to improving the service life of the lens. There is a circle of white digital MAX1.5-MIN1.39 outside the lens, and a small groove on the side. It can be moved with the thimble for optical zoom. Compared with the current digital zoom on the market, the advantage of optical zoom is that it will not cause loss of image quality while changing the size of the image. The resolution is always 1080P.

In terms of interfaces, the Jimi H1 is still rich, with headphone holes in the upper row from the left USB2.0、 Optical fiber output interface, RJ45 network cable interface, power interface, HDMI1, HDMI2/ARC and USB3.0 interface are arranged in the lower row. The introduction of optical fiber interface and ARC interface is more convenient for users to access audio and video equipment.

Jimi has a profound cooperation with Harman Carton. This time, the Jimi H1 was not surprised to use Harman Carton's sound system. The huge volume of the Jimi H1 is largely due to the combination with Harman Carton's speakers. It can be seen that on the back of the H1, there are two horn units like glasses. The size of the speaker has reached 45mm, the sound range is wider, and the bass diaphragm is introduced, Together, they form 2.1 channels, making the sound more powerful. After being adjusted by Harman Carton's team, the high voice is really loud, the middle voice is transparent, and the low voice is powerful. At the same time, the third generation of Live Surround virtual surround technology is used to make users feel immersive when watching movies. The four corners of the machine are equipped with high anti-skid foot pads. On the one hand, it ensures that the sound at the bottom will not be obscured because it is laid flat. At the same time, it also plays a good anti-skid role. By screwing out four screws, a special H1 adapter plate can be added to facilitate users to fix the stand. Multiple annular grids are designed at the bottom, which is very helpful for equipment cooling.

As the most frequently used component of audio and video equipment, its ease of use and hand feel will largely influence the perception of the equipment. The remote control of Jimi H1 is the same as that of Z4 Aurora, and its shell is made of aluminum alloy. It is integrally formed and treated by sand blasting and oxidation. The impact on the touch is hard to refuse. Secondly, The H1 remote control uses Bluetooth connection with high accuracy. In terms of key position design, it uses the combination design of 12 keys+RESET+focusing fluctuation switch. In addition to the usual on-off command, the H1 also adds a voice key, which can search music, movies, etc. directly through voice, and also supports some dialect search, which is convenient for the elderly. The built-in high-efficient lithium battery is used for power supply of the remote control, which can not only be recharged and reused, but also be fully charged at a time, and the standby time can reach half a year. The remote control of H1 has the function of flying mouse. Hold the remote control and shake it to call out the cursor. Users can use the remote control as easily as using a mouse. At the same time, the H1 remote control also has gravity sensing. You can download gravity sensing games in the app store. One remote control can realize the function of the handle.

user's experience

As an intelligent projection, of course, the built-in system is indispensable. The GMUI based on Android 5.1.1 is built in the Jimi H1, which has a clear layout. The four on the left are built-in movies and music. Mango TV source and Baidu music library are used respectively. At the same time, a game store and an application store are built in to facilitate users' one click download and installation, To the right are system settings and installation applications. It is worth mentioning that GMUI does a good job in the novice tutorial. After the first power on, GMUI will use voice, text and animation to prompt users to bind remote control, focus and other operations, without having to read the manual again.

The voice search function can be called out by clicking the voice key on the remote control in any interface. Regardless of the movie or music, the user only needs to say the movie name or actor, which is simple and fast.

In terms of film and television resources, the cooperation between Jimi and Mango TV has gone through several generations of products. In Jimi H1, a VIP membership card of Mango TV was also presented. After recharging, you can enjoy the massive film and television resources brought by Mango TV, which not only eliminates annoying advertisements, but also enjoys many VIP movies.

All resources are genuine authorized resources, and I'm no longer afraid of being told by my friends to watch piracy all day long

In terms of music, Jimi uses Baidu music resources, and the music library resources are also very rich.

Although the Kimi H1 does not have the function of a built-in hard disk, its rich interface resources also provide users with hard disk or USB flash drive plug-in. Through file management, you can play movies, songs, and read documents.

In terms of settings, the stepless zoom and trapezoidal correction are the big highlights of H1. First, the stepless zoom is to fix the projection placement position, change the picture size by setting and adjusting, so as to avoid too large a picture from affecting the viewing experience. The stepless zoom will cause pixel loss. It is recommended that the user first use the optical zoom to adjust.

Due to the building structure and layout, some users cannot face the projection plane horizontally, which leads to imaging distortion and trapezoidal correction. It is to solve this problem that we can understand the role of trapezoidal correction through the following demonstration.

In terms of APP, Gemi Projection has its dedicated mobile phone application, Gemi "no screen assistant". Download the "no screen assistant" of Gemi, connect to the same LAN, and remotely control through mobile phone APP 3D settings and other operations can be completed on the mobile phone. In addition to the remote control function, the screen less assistant can also achieve the same screen with one button, project the mobile phone image to Jimi H1, or synchronously display the projection image on the mobile phone. You can click the image instead of remote control, which is also very practical when entering the account password.

The non screen assistant also has the functions of film and television, music, application on-demand, etc. After clicking the start of screen projection, you can click on on-demand, which is very comprehensive. In addition to network on-demand broadcasting, it can also push local video music for broadcast. Since last year, SARFT has stipulated that TV boxes cannot install APP through USB flash drives. Once the regulation was issued, all TVs have restricted USB flash drives to identify APK files, which has brought great trouble to a group of TV box users, but this trouble has disappeared in Jimi H1, H1 can select the local APK file to upload and install through the non screen assistant.

For some users who are accustomed to using radio and television set-top boxes, they are still accustomed to watching live TV. This is not a problem on the Kimi H1. They can also watch TV on projection by installing a series of live broadcast software such as Xiaowei Live and HDP Live. To facilitate the installation of software, they can choose to install an app store such as sofa butler and download various APPs according to their own needs.

There is also a lot of content in the app store that Jimi has. Except for the apps restricted by SARFT, most of the other apps can be found in the app store, and entertainment and office can be easily handled.

Nowadays, many smart TVs and smart set-top boxes have added the game function. The game function not only allows users to relax after work, but also enriches family entertainment projects and makes life more fun.

We can see in the game center that there are many kinds of games, not only competitive games for adults, but also leisure and educational games for children. The remote control of the Jimi H1 supports gravity sensing, which can be used to play some games that support gravity sensing, and can also be connected to Bluetooth handles, such as FIFA NBA、 Games like Boxing King can also be perfectly supported.

The advantage of high-definition large screen is not only the experience of Guanyin, but also the stimulation of playing games on the large screen. Compared with the screen with three or four monitors, the immersive experience brought by the Jimi H1 is more shocking. In addition to the strong configuration of H1, there will be no sense of stuck in the game. The fan automatically adjusts and accelerates to achieve the ultimate heat dissipation.

As mentioned earlier, the Kimi H1 is equipped with two HDMI interfaces, which can be used to connect a computer host, a set-top box, etc. It is very simple to switch by selecting an input device from the input source on the left side of the home page.

GMUI functions are gradually improved, not only in terms of resources, but also in terms of comprehensive optimization. So much has been said about how the projection effect is. Let's take a look at the following groups of photos taken with the same parameters, aperture f/4.5, ISO-1250， Exposed for 1/40 seconds, with a focal length of 60 mm, the live picture is only cut, and the color is not processed.

Jimi H1 has 1080P high-definition resolution and 900ANIS high lumens. The projection does not use a screen, and it is directly projected on the white wall. Through the display of the above groups of photos, we can see that the H1 projection is still very satisfactory in terms of color performance, H1 shows a high degree of color reproduction, and the color deviation is not serious. The color performance will be better if professional screens or anti light screens are used. The following figure shows the live shot of the projection ratio. At this time, the projection is about 3 meters away from the wall, and the screen size is nearly 150 inches.

Finally, let's take a look at the hardware. The biggest fear of electronic products is heating. Thanks to the numerous heat sinks and metal panels, the temperature of the polar meter H1 is only 36.2 ℃ after working continuously for one hour in the room at 26 ℃, and there is no obvious heating feeling when touching the body with hands.

With such powerful heat dissipation, many people will wonder whether the fan will make a loud noise. In fact, it is not. Through noise measurement, the noise will be reduced to 47.3 dBA when it is about 15 cm away from the air outlet. During normal use, users are almost 30 cm away, and the noise can be guaranteed to be below 45 dBA without coughing loudly, meeting the national noise standard, It will not affect the viewing effect.

After a period of using experience, I feel that the Jimi H1 is very comprehensive and has no obvious shortcomings. As the first 900 ANIS lumen in the industry, the Jimi H1 has overturned people's understanding of the micro projection products in the past, and its definition has also reached 1080P. With the top sound unit of Harman Carton, it launched a 2.1 channel system, which has achieved the ultimate user experience and introduced optical zoom, Lead the micro investment products into a new path. In addition to the extremely high hardware configuration, the system UI of Jimi is also becoming more and more perfect. In addition to the optical zoom of hardware, there is also the stepless zoom and trapezoidal correction of software, so that everyone can choose the placement position. In addition, a series of functions, such as light off machine listening to music, have achieved environmental protection and energy conservation without reducing the user experience, which can be said to kill two birds with one stone. The excellent performance of Jimi H1 in all aspects makes it easy to be competent for both home and office projection. For users who want to build private cinemas at home, Jimi H1 is also the best choice.
