Zimi Z5 has a semi-metal body, and the overall drawing effect of the aluminum outer shell with the top of the space is a bit extravagant. The machine has a brightness of 1000 lumens and uses DLP projection technology with a resolution of 1280 x 800. The trapezoidal correction range reaches ±45 degrees horizontally and vertically. After the boot, the lens bracket automatically lowers and releases to facilitate daily use protection. The top of the fuselage has a virtual sliding touch volume adjustment control area and four physical buttons. Behind the fuselage has a conventional socket, in addition to a USB2.0 interface there is a USB3.0 interface.


Data measurement
For the convenience of everyone's review, the results of our evaluation data are directly released this time. See above. It can be seen that this projector performs satisfactorily in terms of brightness, and all parameters can be excellent. In addition, the color distribution of the screen is even, and it is possible to faithfully restore the color of the screen and to satisfy the user's use is not a problem. At present, this projector is sold in Jingdong, the price is 3,499 yuan, and interested friends can pay attention to it for a long time and choose the right time to start.
The Z5's body design Zhou Zheng, the overall shape of a calm fashion. For home users, the choice of the Zimi Z5 can be placed directly in the living room or bedroom. In recent years, more popular dark colors and hit color home decoration collocation, such products can also be better integrated into the home environment. From the outside, the lens of the Z5 is hidden behind the cover. It will not touch it when it is not turned on, so it will make users feel at ease.

After finishing the screening of 3D movies, 3D functions no longer become furnishings.
In addition to the ordinary rice source screening, this year Z3 also focuses on single-source 3D film sources. For film sources, many users know that their projectors can achieve 3D playback, but they are struggling to find 3D sources. This makes this function gradually become furnishings. The better meters in the content screening process consistently provide users with reliable viewing suggestions. This time, the Z5 is also a separate 3D source.
The good sound quality that Z5 rice possesses can't be wasted, this time the functional design of the physical key of the pole rice Z5, specially raised a key to arouse the function of the polar rice station. As long as the user wants to listen to the song, you can quickly switch to the radio station with one click and listen to the fine sound effects brought by the high-quality sound source at any time.

The advantage of wireless projection via mobile devices is that the operation is more intuitive and easier to use, as long as you click on the touch screen to quickly change the instructions.
Projector Data Testing We mainly use the ANSI standard developed by the American National Standards Association. This standard is also recognized as an authoritative standard in the industry. And consider the following aspects: maximum brightness, peak brightness, optimized brightness, and projector contrast color. Next, I will briefly explain a few technical terms for everyone: The first is the peak brightness, especially in the brightest mode, the highest brightness can be achieved at a single point, generally appear in the center point; maximum brightness, refers to the brightest mode The average brightness that can be achieved on the screen is higher than the reference value of this value; the optimized brightness, also known as ANSI brightness, is the average brightness of the 9 test points in the case where the projector can just distinguish eight gray scales.

Eight gray levels and 13 illumination test points

Two different contrast test methods

Extreme meter Z5 data measured results
data analysis:
Brightness:
With regard to the brightness of the projector, there are three data in the table, namely the maximum brightness, the peak brightness, and the ANSI brightness. In simple terms, the maximum brightness is the average brightness of the screen in the brightest mode of the projector (brightness, contrast, and lamp mode are all adjusted to the maximum). Judging from the results of our actual tests, the maximum brightness of Z5 reached 805 lumens. The peak brightness refers to the maximum value that can be reached at a certain point in the screen in the brightest mode. The peak brightness of the pole meter Z5 reaches 866 lumens.
ANSI brightness refers to the ANSI test standard, so ANSI brightness and maximum brightness are more significant for our reference. From the actual test data, according to the ANSI test standards, the ANSI brightness of the Z5 meter reached 629 ANSI lumens, which is enough for general home users.
Contrast:
In the contrast test, there are two data, one is ANSI contrast and the other is FOFO contrast. In the ANSI contrast test, we used 16 black and white color blocks for testing. The FOFO contrast is tested with the screen completely white and the screen completely black. The contrast obtained by testing 16 points with the ANSI standard is closer to the actual experience of an application such as a PPT presentation. However, if there are some very dark or bright images appearing in the game or playing video, the FOFO contrast level will affect the viewing experience. From our measured data, the Z5 ANSI has a 183:1 contrast ratio and the FOFO contrast ratio is 2338:1.
Color testing is an essential routine test item for daily evaluation. This project mainly aims to understand the color reproduction ability of the machine through the differences between the color test proofs and the real shots. The effect of some models is compared with the original image. Later, you will find larger color casts, such as color brightness, saturation, warm and cold tones, and so on. Here is a real shot of our color test.

It can be seen from the above 4 groups of pictures that the warm part of the Z5 meter is slightly missing and the details are better. Basically can pay attention to the primary colors, and the brightness uniformity is good. In addition, the aircraft's color distribution is uniform and there is no large color deviation. As a whole, the aircraft can meet the daily use of the user.
From these real shots, it can be seen that the polar meter Z5 presents the essence of the original image that can be accurately expressed, which allows the user to enjoy a good image quality. Since this projector slightly raises some color temperature, the picture effects can appear brighter, and it can also improve the level of detail, which is more advantageous for users who like to be immersed in the video and audio world.

Extremely bright, dark and bright layouts are available for this non-screen TV. The atmosphere of the original image can be presented, and the color accuracy is high. There is no saturation in the picture, which is a good way to please the human eye. Although in our test, the color temperature of the aircraft was high, no serious color cast effect appeared after the screen was played.
The focus test mainly summarizes the ability of the projector to focus. This ability is still critical for the daily use of the projector. If the focus of the projected image is inaccurate, even if it is bright and beautiful, it will not make people. The smooth use and clarity are the most important points we see on the screen. We use the PPT test file to examine the focus of the projector.



PPT document real shot diagram
From the point of view of the actual PPT file we shot, the Z5F is a home screenless TV that can also achieve a good focus. The faster focusing speed results in accurate focusing results. With the machine's high brightness and contrast, can achieve a clear presentation of PPT documents. In our actual evaluation process, the aircraft did not appear out of focus and the whole process was smooth. However, after the machine has increased its color temperature, the white area appears to be bluish. For the daily use of a home projector user, it is generally seldom used to place a large screen of a white block such as a PPT with a home console, so the impact is not so great.
Editor's summary: Zimi Z5 this home screenless TV from the body shape to functional design, compared with other products have made a significant brand differentiation. The performance of the aircraft in the actual test, compared to the average home machine has made considerable progress. In particular, the brightness performance, its ANSI brightness above 600 lumens, which is a rare brightness performance in the 3000 yuan micro projector.

The machine has built-in resources, and the system operates smoothly and concisely. In addition, this screenless TV is also exquisite in detail. For example, a manufacturer prescribes a user's remote control usage rule in advance, so that the remote control can retain key functions while reducing keys. This also allows quick operation in dark environments and reduces the possibility of accidental presses. The power-off button on the front-end of the remote control will emit orange light after turning on the power. Many ways to improve the accuracy of the operation of the buttons. In addition, the machine is also a series of speakers with Harman Kardon, rich sound quality, texture is obvious.


Polar meters Z5 box accessories
Judging from the price point and the richness of the machine's functions, it is a product that meets the purchase expectations. Compared with other products in the market with the same price, the machine's features are reasonable and the details are exquisitely crafted. I believe friends who are interested in this model will also have a sense of worth buying after comparison.
