With the advent of the quadrennial World Cup, the one month long fan carnival has arrived as scheduled, accompanied by the grinding jet lag in Europe, and the vast number of fans will experience another month of dark circles under their eyes. However, since it is painful and happy, it is better to give yourself a better experience of watching the game. At this time, it is time to invite the intelligent projector children's shoes.
In the past two or three years, household intelligent projection equipment has been surging, and more and more young people have chosen household intelligent projection equipment. Compared with traditional television, the projector has the characteristics of larger display area, convenient movement, and so on. In addition, the projection picture is a natural advantage of diffuse reflection and more eye protection, especially when there are elderly or children at home who are more sensitive to vision, Eye protection is even more important. Compared with traditional projectors, home smart projectors or screen less TVs also have intelligent operating systems, sound and super long service life. The operating experience is completely consistent with LCD TVs. Therefore, it is a trend for home smart projectors to replace TVs. One of them is the polar meter non screen TV H2 that we are going to evaluate today.
Jimi H series is also the most popular household intelligent projection series at present. The appearance of Kimi H2 has been passed down in one continuous line with H1 and H1S. The appearance design of Kimi H1 has won many design awards such as the German Red Dot Product Design Award, iF Design Award and CES Innovation Award in 2017. H2 continues this classic design and can easily integrate into various home styles.
Appearance and details
In terms of appearance, although the shape is not so novel in the family of Jimi non screen TVs, the classic color matching and the eye-catching segmented fuselage design continue the good reputation of the H series. The exquisite square is complemented by the classic silver fuselage, which is full of heat dissipation holes. This design not only improves the heat dissipation efficiency, but also enables the fuselage to have a richer level.
Under the silver cooling holes on both sides of the fuselage, there are openings for speakers, air inlets, etc. The rear of the fuselage is designed as a black grille, and the position near the bottom is a heat dissipation outlet. When the machine is running, you can feel the hot air discharged from the fuselage, and the bottom of the grille is equipped with various interfaces.
The common interfaces of the polar meter H2 are relatively abundant. From left to right, there are 3.5mm headphone jack, SPDIF optical fiber interface, USB 2.0 interface, USBA 3.0 interface, two HDMI interfaces, RJ45 network cable interface, and the right is the power jack.
The most prominent logo on the front of the fuselage is Harman Carton on the upper right corner, which also means that the Jimi H2 adopts sound technology from Harman Carton. As one of the most experienced audio solution providers in the industry, Harman Carton provides technical support for a large number of high-end audio and video equipment, including Jimi.
With the development of projection equipment from a relatively simple business projector to today's leading role in the living room, it is not only the projection ability, but also the sound effect that can not be ignored. No matter when we watch blockbusters, or watch games, audio and video are inseparable. If clear pictures are the basis, So high-quality audio is icing on the cake. H2 adopts a symmetrical two-way passive bass diaphragm, and uses the bottom space reflection to improve the effect of the resonant cavity, so that the sound performance is more stable and the sense of presence is more sufficient.
In terms of body details, all the buttons are concentrated on the top of the body. The power switch, music key, fast forward key, volume touch, etc. can be easily controlled even if you don't remember where the remote control is thrown at once. At the other end of the button is the logo of Jimi.
The attached remote control is simple in shape, and the functions of all buttons are simple and clear, without difficulty in getting started. The most notable one is the voice recognition button on the top. Its Jimi AI based on DuerOS technology can provide voice search, voice manipulation and other functions. It also adds voice print recognition, which recognizes the corresponding gender and age according to the different voice print of each person, so as to recommend the corresponding personalized content.
In addition, H2 is also equipped with Baidu IoT technology, which can control other intelligent devices connected to DuerOS through H2's voice function, becoming the control terminal of DuerOS. With the growing tide of smart home, intelligent life is not far away from our life, and more and more intelligent products will join the IoT platform in the future.
Projection effect test
H2 adopts an intimate electric lens cover, which automatically opens when the machine is turned on and closes when the machine is turned off. The lens can be better protected without users' concern. This H2 uses the display technology from DLP with a 0.47 "DMD RGBB-LED display chip, and uses a four channel optical path design, which can provide a display effect of up to 1350ANSI lumens. Compared with the 900ANSI lumens of the previous generation product (polar meter H1), it has been greatly improved. It is also one of the models with the highest brightness in the current price range, Now let's take a look at its actual projection effect.
Focusing and intelligent correction experience
Intelligent correction demonstration
The first is focusing and intelligent correction. Jimi H2 is equipped with a full automatic focusing function, which automatically monitors the distance and angle from the projection surface when it is turned on for automatic focusing. In addition, H2 is also equipped with one button intelligent auxiliary correction function. Long press the function key to activate the shortcut menu and enter the intelligent correction program. Intelligent correction includes refocusing, automatic correction and other functions, which can quickly repair the deformation of the picture, restore the square projection state, and eliminate the tedious steps such as manual trapezoidal correction. Even if the projector needs to be moved frequently, it can be quickly put into use again. In a word, it can be concluded that even the elderly and small white users can start up and use it immediately.
Projection sharpness test
Resolution test
Color performance test
Shadowtone Hierarchy Restore Test
In the objective test, Jimi H2 showed the rare exquisite performance of the projection equipment (the actual shooting effect is slightly different from the naked eye). Both the resolution test and the color performance test are outstanding among the models at the same price, especially the color performance test. The color sphere is soft and has no obvious color band; In the test of similar color bands, only 135 and 120 are difficult to distinguish, and other color bands can be clearly distinguished. Level 32 black and white tone level distribution test can also distinguish about level 28.
Actual projection effect test
However, testing does not represent everything. It is always true picture performance that can finally conquer consumers. Jimi H2 uses a variety of technical means to improve the picture effect, such as HDR10 decoding, variable aperture, image quality enhancement technology, motion compensation, etc. They work together to improve the display effect, Now let's see how the real projection effect of Jimi H2 is.
Animation projection test
Unlike conventional landscapes or portraits, animations often have clear colors and strong contrast of different colors, which can better show the color tendency of projection equipment.
Static picture projection test
Scenery is the most common use scene in our daily use. The transition of different colors is relatively mild, and there is no very strong color contrast like animation, which can better show the color transition effect.
Demo video test
For the demonstration video, a high-resolution test video with bright colors and rich dynamic content was selected to show the projection effect under dynamic changes.
In the test of the whole projection effect, Jimi H2 has shown a very strong strength. It is sensitive and accurate in automatic focusing, and has built-in intelligent auxiliary correction, which greatly reduces the use cost. In the performance of the projection effect, 1350ANSI lumen brightness has left us a deep impression. Compared with the previous generation of products, the brightness has been greatly improved, which has also expanded the use scenarios of H2. The usability of H2 has been significantly improved in daytime non direct sunlight, which is also the biggest improvement compared with the previous generation of products. It can be said that it is almost difficult to meet competitors at the same price.
Motion compensation function
In addition to the relatively conventional functions, the more important one is the motion compensation function for the dynamic and intense picture of watching the ball. For some video signals whose frame rate is not high enough, the improvement is particularly obvious. For example, in the rolling process of football, after turning on motion compensation, the smoothness is better, the picture connection is more natural, and the dragging is better improved, It effectively reduces the feeling of insufficient frame rate.
Turn on motion compensation
Turn off motion compensation
Children's shoes who often watch sports games may know that the TV signal is usually 60 frames, while online video can hardly reach this frame rate, and only about 24-30 frames of video are provided. It is no big problem to watch ordinary variety shows and TV dramas, but it is more urgent to watch more intense and coherent videos, such as football games, It is inevitable that the picture will feel jittery and trailing.
At this time, the models without motion compensation can only stare. The models with motion compensation, such as H2, use the built-in motion compensation interpolation algorithm to compensate for the images. Although the effect of the algorithm compensation is still different from the original 60 frames, it has been greatly improved compared with the models without motion compensation. For long-term viewing of network video, Especially for users who like sports competitions, sports compensation is very necessary. Wave goodbye to the trailing video.
System experience
In terms of the system, H2 is equipped with GMUI 3.1.0.1 system, which has several fluency improvements. With MStar 838 64 bit CPU and Mali-T820GPU, it has faster response and smoother operation, which is more than three times higher than the previous generation system. In addition, the official said that there are thousands of experience optimization, faster response and more user-friendly operation. However, AI voice and children's desktop are more worthy to be mentioned.
For users with elderly or children at home, these two designs are user-friendly designs that can improve usability. Pressing and holding the voice assistant can easily complete most operations, greatly reducing the threshold for use.
Children mode is a dedicated anti addiction desktop for children, which can be set according to the age and gender of children, and can also be customized to prevent children from indulging in use. When releasing the child mode, it is necessary to answer a mathematical problem to prevent children from solving it by themselves.
summary
As the main model of Kimi in the home market in 2018, H2 has a proud performance in several aspects, such as 1350ANSI lumen brightness, intelligent auxiliary correction, motion compensation technology, Harman Carton speakers, etc., which are more competitive selling points, especially the highest brightness and motion compensation. The former is the best among the models at the same price, while the latter has improved the smoothness of the picture, which is very helpful for videos with intense picture dynamics. These two items alone are enough to lead many competitors.
There are happiness, joy, pain and tears in the world of football. Just as life is full of ups and downs, the Russian World Cup has kicked off. I hope that every fan will have an excellent display device with you while enjoying football. Jimi H2 is a choice worth considering.
