"Preface
Jimi is an intelligent projection brand rising in the Internet era, and has strong attainments in household intelligent projectors and micro projectors. H1 series screen less TV launched in 2016 has been highly praised by the market for its exquisite appearance and relatively excellent image quality. This kind of "TV" that can be broadcast directly only by a clean white wall has also been recognized by more and more consumers.
The hot market has further stimulated the rapid development of industry technology. Jimi has added more practical functions such as intelligent auxiliary correction to its new products this year. The new H2 series screen less TV has been released. Compared with the previous generation of products, it uses more new technologies such as image quality effects, intelligent auxiliary correction and intelligent IOT, which further improves the user experience. H2 slim, the most cost-effective one, has come to the evaluation room. Let's take you to learn more about its performance.
Cool design
Compared with the previous generation of screen less TV H1, Jimi H2 slim is smaller. Especially from the front of the silver body with black dust screen cover, it inherits the design style of Jimi Z5 portable micro projection.
Because the fuselage is more flat, Meng Meng's big eyes occupy a larger proportion on the front face of the projector. A red ring is added to the lens, which increases the texture a lot. Compared with H1, which needs to manually open the lens cover, Jimi H2 series adopts a comprehensive automatic switch of the lens cover, which can be automatically opened and closed at the moment of clicking the power key, which can not only be convenient, but also prevent dust accumulation.
The body surface of Jimi H2 slim has been metal frosted to improve the texture. All buttons are arranged in an arc on the top of the fuselage. When the machine is turned on, it will flash white light, adding a bit of poetry.
All the interfaces of this screen less TV are designed on the back of the fuselage. There are USB3.0, HDMI and optical fiber interfaces, reflecting the importance of entertainment. In order to enhance heat dissipation, the whole back is covered with heat dissipation slots, which can achieve better heat dissipation effect with internal fans.
The remote control is basically the same, and the voice buttons are very obvious. In the later evaluation link, we will try its voice function in detail.
Hardware and software configuration of H2 slim for Jimi screen less TV
Jimi screen less TV H2 slim is equipped with 0.47 inch DMD chip, MSTAR 6a838 64 bit chip and Mali_ T820gpu, 2GB ram and 8GB ROM can play full HD movies smoothly, which is better in system fluency and image processing. It is worth noting that the 0.47 inch DMD chip used by Jimi screen less TV H2 slim has a standard native 1080p core. Compared with some micro projectors using 0.33 inch DMD chip, the picture quality details should be clearer and sharper.
The latest gmui3.1 customization system of Jimi is configured on the basis of sincere hardware. Compared with the previous version, the overall interface is more concise and easy to understand, and the fluency and stability are also greatly improved.
Interface switching (from "my" to "application")
In terms of film and television resources, they are also more massive than before. In addition to cooperating with mango TV, Galaxy kiwi fruit and Sohu Video, they also have pptv poly sports, baidu music and dragonfly FM music library resources. Just looking at film and television and music resources, we can see that the content is indeed very rich.
In the world cup section, there are not only today's World Cup forecast, but also yesterday's game. All you want to know is here. During the live broadcast of the world cup, click Youku app scan to directly enter the live broadcast for viewing, or replay previous games. The game can support 1080p film source, so the picture is very clear.
Setting of Jimi H2 slim screen less TV
Of course, a good screen less TV should not only have picture quality, but also have good user experience. Jimi screen less TV H2 slim can not only support automatic focusing, but also carry out 45 degree up, down, left and right automatic trapezoidal correction through "intelligent auxiliary correction". The projector can be placed on the bedside table or desk and tea table in time, and can still get a very square picture when it is placed obliquely on the white wall.
Oblique auto focus function
When using this function, the user needs to click several times. First enter the application page in the UI main menu, then click "system setting" below, then click "trapezoidal correction", and finally click the pop-up "intelligent auxiliary correction". After that, the projector will adjust the picture to be square and clear in a few seconds, and complete automatic correction and automatic focusing in one breath. In addition, the projector also provides a manual adjustment option to meet the almost abnormal requirements of "obsessive-compulsive patients" through omni-directional fine adjustment of four corners. All the pictures in this evaluation are real photos. Is there an illusion of "screenshot"? It is precisely because the editor manually adjusts the projector picture to the best with the camera lens.
Before adjustment
After adjustment
Let's take a look at other main settings. Users can adjust the picture frame, image quality and video specification of Jimi H2 slim.
Users who have too small walls at home don't have to worry. The stepless zoom function can make the picture smaller without losing clarity.
In video adjustment, in addition to switching between 4:3 and 16:9, MEMC motion compensation can also be set. This is a technology to make the moving picture smoother through interpolation. In short, let the chip predict what the next frame will be after each frame, and then generate and insert the picture frames that are not in the original video. Previously, this technology was generally used in medium and high-end smart TVs, and rarely appeared in projectors, especially micro projectors. In the actual measurement, it is found that Jimi H2 slim can obviously feel the smooth picture after turning on motion compensation, just like turning on the high frame rate mode in the game, making the picture more smooth and natural.
motion compensation
It is particularly worth mentioning that here you can also see the new functions of Jimi H2 series, such as voiceprint recognition, lot platform and so on. Voiceprint recognition can be used to recognize the voices of different users and prevent bear children from secretly watching cartoons for a long time, while IOT platform can be used to control other smart appliances at home, which is also practical for user friends who install and use smart homes such as smart air conditioners and smart curtains.
Picture and sound quality experience
Through the actual measurement, the nominal 1100ansi viewing brightness of Jimi screenless TV H2 slim is in line with the actual viewing brightness. When combined with full HD physical resolution, it can project a clear and beautiful picture. There is no need to pull up the curtains during the day and turn off the lights at night. This real and natural experience deserves the title of screen less TV.
The measured brightness exceeds 1000ansi lumen
By comparing the pictures of turning off the light and turning on the light, it can be seen that it has little impact on the picture quality, and there is no obvious color deviation
Next, take a look at the color and gray scale performance of this screen less TV. In order to enable all netizens to experience the real image quality of Jimi screenless TV H2 slim with the editor, the following pictures are all taken from the projection screen without any post-processing optimization.
It can be seen that in the gray-scale picture of Jimi H2 slim, the darkest and brightest parts can be clearly reflected, and the 4% difference between the left and right grids can also be shown. If the brightness is insufficient and the gray scale ability is poor, the left part of the picture will be dark and the right part will be white, which can not reflect the sense of hierarchy at all.
Let's enjoy a few more landscapes. Thanks to the support of hdr10, the pictures look full. Even the branches and buildings hidden in the night can show the details attentively. In the performance of bright pictures such as sunshine and white clouds, there is no exposure, and the picture and color are relatively clear and natural.
Next, we use Jimi H2 slim to enjoy several 1080p films. The motion compensation function of the projector makes the film play more smoothly without tearing and jamming. In addition, the high dynamic effect brought by hdr10 also makes the picture more realistic and natural, and the outline in the dark is also clearly visible.
No matter how good the viewing effect is, it is inseparable from the excellent sound quality. The Jimi screen less TV H2 slim has been adjusted by Harman Caton's master standard and matched with two 40mm double speaker units. The sound performance is delicate and lifelike. Whether it is the dialogue of characters or the explosion and roar of some large fields, it sounds clear, and the medium and high frequencies are relatively natural, Unlike the entry-level intelligent projector, it has a serious sense of distortion. In addition, this Jimi H2 slim can also be transformed into a WiFi Bluetooth audio with one button to play online music through WiFi or mobile phone through Bluetooth.
Intelligent voice experience
In the field of television, intelligent voice control has become a standard configuration. New TVs listed by major domestic brands this year have been equipped with intelligent voice control function as standard. Jimi H2 slim is also further intelligent. The equipped Jimi AI makes the voice interaction more accurate. Most operations such as film search, viewing and opening applications can be completed by moving the mouth.
Users can not only search movies and TV dramas according to the film title, but also directly select collections. For example, they can issue a voice command "I want to see the hunting ground", and all video resources about the hunting ground will be launched in a few seconds. After saying the voice command "I want to see dad go home Episode 2", the second episode of the TV series will be broadcast directly in a few seconds.
In addition, you can also search for films according to your favorite actors. For example, by issuing a voice command "I want to watch Lu Han's TV", you will directly jump out of the TV series starring the actor.
Users can also choose the types of films according to their preferences. After reporting "American war films", they have also received many relevant recommendations with high accuracy.
You can also get local or remote weather forecasts through voice commands. People who need to travel frequently don't need to check the computer before departure. You can ask Jimi directly.
Heat dissipation and noise
The compact body brings some challenges to heat dissipation, but thanks to the relevant components of real materials, the heat dissipation performance of this Jimi H2 slim can still be expected.
The central air conditioner of the office building provides an ambient temperature of 26 ° C for the evaluation room. One hour after startup, the measured temperatures at the lens, top, side and back are only 27, 31, 28 and 34 ° respectively, which is a very safe temperature. The risk of system crash is very small and will not lead to lens overheating and distortion.
Some projectors rely on high-speed fans for heat dissipation, resulting in excessive noise and interfering with the viewing experience. With the excellent heat dissipation capacity of this Jimi H2 slim, with the optimized internal heat dissipation design, real large heat sink and the adoption of silent fan, the editor can hardly feel the existence of noise during the experience.
summary
After some experience, what's your impression of this Jimi H2 slim? If you want to sum it up into a word, you can't think of it at once. Maybe it has a lot of highlights. Let's finally touch it: in terms of image quality, the real 1080p, together with the golden combination of HDR and motion compensation, is enough to meet the needs of most home users to watch HD movies. In terms of sound effects, professional Harman Caton system can also achieve good results at home. Coupled with the highly friendly use experience, you can accurately search the film by moving your mouth, throw a normal picture when you put it in a corner, and fine tune it to the extent that it looks square from the camera lens. The author's obsessive-compulsive disorder has also been cured. It can really be said to be more omnipotent.
However, one thing to note in use is that Jimi can't focus automatically in the whole process for the time being. Once it feels blurred after startup, or it feels a little hot out of focus after long-term use, it can focus manually or click "intelligent automatic correction" in the setting to focus automatically. Finally, I would like to share with you that many technological advances have not piled on the price of this Jimi H2 slim screen less TV. At present, the price of JD is only 3897 yuan. Among the products at the same price, its functions are relatively comprehensive and its image and sound quality are also prominent.
