As the first domestic brand to launch 1080P full-HD non-screen TV, the launch of the Mi Mi H1 caused a sensation in the entire smart projection industry, and it also marked the take-off of the entire smart projection industry. One year later, the classic rice H1 has been upgraded several times. From H1 Aurora to H1S, to the current H1S Aurora, each update has a sensational effect. As consumers, when selecting products, in addition to considering product performance indicators, they need to combine their own needs and expected input budget. Under the premise of adequate budget, the Mi Mi H1 series is nothing more than the user's best. Choose one. However, when the overall budget of the consumer is insufficient, the Z5 is the best choice for such users. Although the Z5's resolution and brightness are inferior to the H1 series, it can also satisfy most users. The most difficult thing in daily observation needs is that the price of products should be more grounded and more in line with the expected input budget of mass consumers. 
From the hardware point of view, Zimi Z5 screenless TV uses Texas Instruments mainstream 0.45 "DMD chip, with OSRAM's latest RGB-LED light source, with the industry's mainstream physical resolution of 1280 * 800 and 1000ANSI lumens brightness Values, even in a bright environment, can project a sufficiently bright projection screen. At the same time, Zimi Z5 non-screen TV also has a trapezoidal correction function of ±45° vertically, ±45° left and right, which can guarantee a greater degree of The machine does not have to be placed on the central axis of the projection screen but also projects a perfect proportion of the projection screen.
Judging from the hardware parameters given by the official meter, the Z5 Smart Projection will be an idealized intelligent projection product that is not critical, and whether the actual effect is as described by Zimi, and look down. !
Packaging and design Let's take a look at the packaging of Z5. The Z5 still uses the H1S packaging style. The top of the box comes with a handle, and a small handle can reflect the carefulness of the rice when making products.
It is believed that many users will choose to use lifting or wall mounting when using projection products. Because the bottom of the pole Z5 is not an international standard hole, in order to take care of the needs of such users, a standard one is specially designed at the factory. Z5 dedicated transfer tray, very warm heart.
The moment of opening the big package, even Xiao Bian can not believe this is a projection product, in the impression of Xiao Bian projection products are generally relatively bulky, generally small and similar products like "projection toys" small The editor has also seen, but through the parameter comparison, it can be really uncommon to be able to achieve the parametric index of the quasi-professional home projection and to make the product so compact.
On the three sides of the product, a metal aluminum shell is used. The logo of “Harman/Kardon†on the front symbolizes the sound quality assurance of the Z5. The opening of the sound cavity with positive sound can more ensure the user can listen during use. More three-dimensional sound field.
On the back of the machine is the centralized location of all interfaces. Various rich interface configurations including USB3.0, HDMI2.0 can meet the needs of users in daily use to the greatest extent, in order to ensure that users are using multiple inputs. When the device does not have to be plugged and unplugged frequently, the Z5 uses a dual HDMI2.0 configuration for the interface configuration. At the same time, the HDMI2 supports ARC, and the audio signal can be transmitted back to the amplifier via the HDMI cable through the HDMI2. demand.
In terms of accessories, the Z5's configuration is quite satisfactory. Apart from the Z5 special adapter plate, other accessories are common accessories for projection products, such as: remote control, 7th battery, power adapter, warranty card, manual and the like.
Speaking of the remote control, in fact, Xiaobian most misses the metal remote control of the extreme rice H1 era, not only work fine, solid materials, and feel is just right. Of course, the polar meter Z5 remote control is not bad, at least in terms of workmanship and materials have maintained the original level, just after the use of ABS plastic material feel slightly worse.
UI interface To tell the truth, for the part of the UI system of the early Mi, there are reservations about the small series, although the interface is simple and refreshing, but the content is not rich enough, you want to find a certain application and the like have to properly study it. I wish. When Xiao Bian opens the Z5, it is no longer an early UI interface. The brand-new UI interface adopts the waterfall-style method widely used in Internet smart TV products to display. While ensuring the simplicity of the interface, Enriched the presentation of content.
In addition to making a revolutionary breakthrough in the UI interface, the Extreme Z5 no screen TV has also made a more reasonable plan for the presentation of the content. The topical content of the same category is pushed, the latest cinema content is recommended, and the upcoming line is large. Notices that are not visible on the early UI, such as advance notice, are displayed on the Z5's interface one by one.
In addition to the use of the current mainstream waterfall form in the presentation of the content, the Zimi Z5 no screen TV also uses a modular waterfall form display on the setup menu.
The orderly setting of the class items is divided into five categories, which are ordered from the main to the top and from the top to the bottom. The main category sort order is network settings - screen settings - sound settings - system settings - universal settings. 
For the vertical/left/right ±45° trapezoidal correction introduced by Kamitsu, we also found a more interesting problem by comparing the tests. In the range of 0 to 40°, the trapezoidal correction is indeed performed, but when the angle exceeds 40°. After a bit like the chamfering feeling in PS processing.
In the aspect ratio, Zimi Z5 can present the picture in various common proportions through the system software algorithm. However, in the actual test, we found that the ratio of 16:9 and 16:10 provided in the aspect ratio is two. There was no significant change. By adjusting the aspect ratio of the screen, the display ratio did not change. However, when playing a movie, the ratio of the picture changes significantly when switching between these two proportions. For this phenomenon, Xiao Bian understands the system BUG. As for the built-in BUG of the background image or the BUG of the system itself, it must be forbidden. And you know.
For different projection environments, Zimi Z5 screenless TV gives a good solution. Under the system, different projection modes can be selected for different projection environments, so that targeted projection can be achieved with better projection screen effects.
In addition to the vertical/left/right ±45° trapezoidal correction, the Z4 TV screen also incorporates the mainstream motion compensation, 3D noise reduction, and other functions of smart TV products. The addition of these functions can significantly improve the details of the projection screen. The promotion.
2G fuselage operating content and 16G fuselage storage settings, configuration is not too bad is not considered the industry's top match, law-abiding.
Performance Test With the rapid development of projection technology, smart projection products have already passed the era of product problems in the previous two years. Today, intelligent projection products using LED light sources not only achieve a quasi-professional level in hardware configuration and performance indicators of the product. The indicators of home theater projection products also meet the needs of most users in terms of color performance.
The above picture shows our original effect on R/G/B three primary colors of the screenless TV Z5. The upper part of the figure is the standard R/G/B primary color image, and the lower part is the Z5 projection screen real shot image. . Through intuitive comparison, we can see that the Z5 screenless TV is quite accurate in the red, green is slightly dark, blue is slightly purple (because the shooting equipment determines the final effect can not be exactly the same with the actual projection effect, the actual To express the effect due to the image).
In terms of color transparency, the performance of the Z5 Smart Projection is also very good. The transitions and transitions between the colors are relatively natural and there is no obvious rainbow effect.
Grayscale Testing - The more common method of contrast effect testing in testing. Zilmi Z5 no screen TV official does not give the specific value of the product, through the test chart we can intuitively see this product in terms of contrast performance, the effect of contrast can not be compared with the professional-grade cinema projection, but In the field of screenless TV is also considered to be doing better.
In terms of power consumption, the average power consumption of the entire Z5-based screenless TV in the standard mode is about 78W.
In terms of noise, the official data provided by the company is that the noise in a range of 1 meter is less than 30dB. In our tests, the noise was about 53dB at a distance of about 10 centimeters from the machine and about 42dB at a distance of 1.5 meters from the machine. Test room ambient noise 20~25dB.
Online video test to say that the recent fiery drama, it should be non-"Chu Chuan" is none other, whether it is in the bus or subway on the commuter, or the free space between the tea and rice, always see many holding mobile phones to recover Drama people. Zimi Z5 no screen TV in this regard is a very good recommendation, in a prominent position in the UI interface for the user to push the fire drama, with hundreds of large screen to watch such a fire, comparable to holding a small cell phone It's much more comfortable to watch.
Do not talk about the fineness of the picture, from the size of the screen alone, the polar meter Z5 no screen TV has already won the mobile phone screen, the visual effect of the ultra-thousands of projection screen is like a theater-like shock.
In addition to the large-size projection screen, the color and sharpness of the screen are also worth noting. The projection screen is colorful and has a clear sense of hierarchy. After opening VIP members, they can enjoy 1080P or even 4K ultra-clear video resources online.
As a main-home screenless TV, Zimi Z5 has also done a good job in supporting 3D resources. When playing a 3D movie, the 3D function menu of the system can be evoked by long pressing the remote control menu key, and the corresponding setting can be made according to the format of the 3D movie. In 3D playback, it is found through measurement that when playing a 3D movie, whether it is 3D playback or converted to 2D playback, the navigation information on the video does not remain in the 3D mode, thus it can be seen that the pole Z4 is embedded inside. There is still room for improvement on the player.
Left and right formats of 3D video are still quite shocking, especially when viewed at close range from a 150-inch screen.
Of course, even a 3D format movie can be converted into a 2D movie by the player's conversion function. It's worth noting here that even after converting to 2D, the movie information at the player's navigation information is still two.
4K test In terms of video compatibility, Zimi Z5 screenless TV also has good compatibility. It is compatible with common audio/video encoding and packaging formats, especially in the frontier 4K video. To the perfect compatibility, due to the Z5's ultra-high configuration in hardware, it will not appear to be stalled when playing normal 4K video (Ultra-high bit rate 4K test video will be stuck).
For the Z5, we also tested the contrast in front of it. What will be the final effect when the outstanding contrast is reflected in the video frame? Through the above figure, we can intuitively see the dividing line between the silhouette and the background, and the three-dimensional character is fully reflected.
Zilmi Z5 no screen TV in the comprehensive color performance is relatively outstanding, for the average consumer, the effect is enough for daily use, but for the more demanding professional players, the color effect may need to be improved. In addition to the color performance, the overall picture can also be seen in the picture above, and the white part is slightly blue.
The two main figures are mainly red, combined with the depth of field of the scene, the detailed level of the projection screen requirements are very demanding, only when the projector in the level of detail to achieve a certain degree of functionality in order to truly restore the depth of field of the screen ideal come out. Through the test, the overall performance of the screen-depth TV of the Zimi TV Z5 is relatively good, and the transition from the red light to the dark is smooth and the details are in place.
The internal structure as an old driver, after testing the machine to carry out a deep excavation of the internal structure of the machine, it is indispensable, the following guys will witness to Xiaobian is how to Miji Z5 this non-screen TV "large Unload eight pieces."
The first is to unpack the machine housing. After removing the housing, all the components of the machine are reflected in front of the main board, light engine, lens, speaker, and so on.
Zimi Z5 has the power of the electric lens door, so after opening the machine you can see the inside (on the left side of the lens) using two small motors to drive, the motor marked in the green circle on the way for the lens focusing, The motor marked in the red circle is dedicated to the electric lens door.
Our common projection products are only equipped with a fan design, and taking into account the brightness of the Z5 has reached thousands of lumens, in order to ensure the stability of the machine at work, the pole meter uses a dual-turbine suction fan silent fan cooling design, To the maximum guarantee that the machine will not appear burning machine phenomenon even under long-term use.
Harman Kardon audio, this has always been a proud point of the pole. The Z5 no-screen TV also follows the custom-made sound of Harman Kardon for the Z5. The 40mm dual-speaker unit is designed to be master-calibrated by Harman Caton. The sound is delicate and exquisite. Whether watching a movie or playing games Listen to music, the sound will be transmitted to the user's ears.
On the PCB side, the Z3 has adopted up to three motherboard designs. From the aspect of functionality, we can roughly classify these three PCBs into three categories: power distribution, optical processing, and intelligence.
As a no-screen TV that hit the home market, the Z5 has adopted the video processing chip of the TV for the first time - i-chips ip00C787 frame loss compensation IC. Through i-chips official technical parameters, ip00C787 can be perfect Supports tilt rotation at a 45-degree angle from the horizontal/vertical line, with a maximum rotation angle of 45 degrees (supports rotation at any angle), while the local vertical direction supports a reduction rate of 0.3 times. The most noteworthy thing is that point-to-point fusion can be done regardless of correction.
In the smart part, the pole meter processes the CPU information, so it is not intuitive to see which model of the CPU architecture is used.
Test Summary and Comments Prior to the launch of the MiZi Z5, in the 720P-level product camp of smart projection products, the product design of Miji has always been a "flattened" route. The launch of the Mi Z5 no screen TV is not only subversive. Our concept of development awareness of the 720p level product line of the meters, but also allows users to better see the strong strength of the pole rice in product development.
Throughout the testing process, the Z5 has stable performance, functional and practical, easy to operate, easy-to-use projection screen, near-perfect projection screen effects, and excellent sound effects. Although the Z5 is only a 720P product, it has been fully able to meet the general public level consumers. Daily viewing requirements. Whether it is used in the customer or the bedroom, if the projection screen can be controlled within 150 inches, the projection screen can be comparable to the LCD TV at an effective viewing distance.
Trial review:

function test
Looking at the entire field of intelligent micro-investment, we must say that the unique technology of extremely rice, trapezoidal correction function is definitely a big killer of extreme rice. When the industry stays in the vertical ±35° trapezoidal correction, the pole meter introduces a vertical/left and right ±35° trapezoidal correction. When the industry follows vertical/left and right ±35°, the pole meter has developed to vertical/left and right ±45 °, not to mention this ± 45 ° in the end the user has what kind of practical use, at least in the technical breakthrough on the rice has already occupied the initiative. Online video test to say that the recent fiery drama, it should be non-"Chu Chuan" is none other, whether it is in the bus or subway on the commuter, or the free space between the tea and rice, always see many holding mobile phones to recover Drama people.
