In recent years, with the rapid development of intelligent projection equipment, more and more first-line city users choose household intelligent projection equipment to replace the previous TV. The reason why users choose it is that the projector has a larger display area and is more convenient to move. As a pioneer in intelligent projection equipment, Jimi released a new generation of projectors H2 and H2 Slim earlier this year. In our previous evaluation, the performance of Jimi H2 was satisfactory. What about the performance of H2 Slim launched in the same period?
Appearance and details
The outer package of Jimi H2 Slim adopts a rectangular shape. The cover is a simple front view of the product, with the product name H2 Slim marked in the middle. The main color of white is consistent with the previous products of Jimi.
In terms of appearance design, the Jimi H2 Slim continues the consistent style of the H series: exquisite rectangular shape coupled with the classic silver body, both sides and the front are connected together, with strong industrial design elements. The conventional electric sliding door of Jimi is naturally not absent. With the user switching on and off, the lens cover will automatically open, providing better protection performance.
Different from the H2 released at the same time, the Jimi H2 Slim has only designed a black grille heat sink at the rear of the fuselage, which is very regular. During operation, you can experience the hot gas discharged from the fuselage, and the upper part of the grille is equipped with various corresponding interfaces.
The interfaces of the Jimi H2 Slim continue the tradition and are very rich - from left to right are the power interface, RJ45 network cable interface, HDMI interface, USB 3.0, USB 2.0, SPDIF optical fiber interface and 3.5mm headphone jack, which are completely free of problems for general home use.
The most prominent logo on the front of the fuselage is the Harman Carton in front of the speaker. Like other models of the Kimi, the H2 Slim also uses the sound technology from Harman Carton to ensure that users can enjoy excellent audio-visual experience. Harman Carton is a famous audio solution provider in the industry, providing technical support for many high-end audio and video equipment in the market. Jimi has cooperated with Harman Carton since its inception, and we have also experienced the strength of Harman Carton in its products.
All buttons of the H2 Slim are arranged at the rear of the top of the machine body. The power switch, music key and fast forward key are physical keys. The volume adjustment is touch key. A light bar is arranged in the center of the two rows of keys to indicate the working status. The complete key layout ensures that even without a temporary remote control, it can be easily controlled and used.
Like the newly released products of Jimi, H2 Slim is also equipped with Baidu's IoT technology. Users can use H2 Slim's voice function to control various intelligent devices connected to DuerOS, making H2 Slim the control terminal of DuerOS. With the improvement of smart home, more and more smart products will be added to the IoT platform, and the functions of H2 Slim will become more powerful.
Compared with H2 released in the same period, H2 Slim maintains a similar level in parameter specifications: 1080P native resolution, 1.2:1 projection ratio, 1100ANSI lumen brightness, intelligent correction, voice control, etc. In this case, it can also reduce the size and weight. The word "Slim" deserves its name.
Measured projection effect
H2 Slim maintains the advantage of Jimi in hardware. It uses a 0.47 "DMD RGB LED display chip. It is still the DLP projection technology commonly used in the industry. It uses a new optical path design, with brightness up to 1100ANSI lumens. It has almost no rivals in the same price. The book parameters are very strong. Let's take a look at the actual projection effect of H2 Slim.

Shadowtone Hierarchy Restore Test
In the projection definition test of polar meter H2 Slim, H2 Slim performs very well. In the test of resolution, color, and tone level restoration, they all have excellent performance in products at the same price. The color performance test is very good for the restoration of color bands, which is difficult to distinguish between 120 and 135; In the tonal level distribution test, 32 levels of black and white levels can be distinguished to about 27 levels, which is a good level for the projector. (There is a slight difference between the live shot and the naked eye)

Live video projection
In the actual projection test, we have to say that the built-in intelligent auxiliary correction of the Jimi H2 Slim is very powerful, and the automatic focusing is accurate and fast, which greatly reduces the use cost of ordinary users. The real projection effect is satisfactory. Whether it is facing high contrast pictures, landscape photos testing color transitions, or videos with high dynamic requirements, the Jimi H2 Slim can be said to be commendable. The brightness of 1100ANSI lumens is good even in the daytime, as long as it is not in direct sunlight, and the usability is very high, which is one of the advantages of the polar meter H2 Slim compared with competitors at the same price.
Another killer feature of the Jimi H2 Slim is the built-in motion compensation function. For watching football games and other dynamic images, motion compensation is very effective, and some videos with low frame rates are also significantly improved. Unlike the 60 frame TV signal provided by radio and television, online online video basically provides 24 to 30 frame video sources, and only a few websites or videos will provide 60 frames. It is difficult to detect when watching variety shows and TV plays in daily life, but when watching more intense and coherent videos, the picture will inevitably shake and drag.

H2 Slim compensates for the image through the built-in motion compensation interpolation algorithm, which has been greatly improved compared with other products without motion compensation. For users who like watching sports games through online video, the built-in motion compensation function of H2 Slim has been greatly improved, and they no longer have to endure the video that often lags behind in the game.
GMUI system
On the system, H2 Slim naturally carries its own GMUI. The new GMUI has many improvements. The built-in MStar838 CPU+Mali-T820 GPU is exactly the same as H2. The overall response of the system is fast and the operation is smooth. GMUI functionality is very perfect, there are all that should be, and the operation is more user-friendly. Thanks to the newly added IoT technology, AI voice control is more prominent.
Especially for users with elderly or children at home, AI voice control can significantly reduce the use cost and better experience the intelligent projector. The experience of AI voice is satisfactory. The recognition rate and response are excellent, and most operations can be easily completed. The threshold for the use of intelligent systems has been greatly reduced. If there are all kinds of smart devices in the home, they can be controlled through the Jimi H2 Slim, and become the control center of smart home.
summary
Although the name of the polar meter H2 Slim is "Slim", its specifications and performance are all "Slim", including intelligent auxiliary correction, motion compensation function, Harman Carton audio technology, and H2 Slim has some functions. Compared with competitors at the same price, the brightness of 1100ANSI lumens is enough to stand out from the crowd, the actual projection effect is excellent, and the combination of software and hardware is excellent.
If users are planning to add a display device to their home, and want to replace the traditional TV with a new intelligent projection device, then the H2 Slim, which has always been cost-effective, is very suitable for new users to choose as the entry projection.
