Millet Mi laser television experience: 150-inch comparable theater, 9999 yuan cost-effective

With the improvement of the quality of life in these two years, the size of people buying TV is also increasing. From the 55-inch sale of two years ago to the surging sales of 65-inch and larger TVs in the past two years, the people of the country have decided to increase the TV size. The requirements are getting bigger and bigger.

However, the size and price of the current mainstream LCD TVs have increased exponentially. For example, the average price of an ordinary 55-inch TV is three or four thousand and 65-inch, and seventy-eight or seventy-eight. The 70-inch one has ten thousand. If it is more than a hundred inches, the price will directly reach hundreds of thousands of levels. So on a large-sized display, projection becomes a low-cost solution. In the past two years, major manufacturers have introduced laser projections.

So what is the performance of Xiaomi’s product? Can you replace your home TV product? Sina Digital got this product for the first time and will bring you a simple experience.

Mijia Laser Theater

In terms of appearance, Mijia Laser Theater still maintains the minimalist design concept of the brand. The main body is made of white plastic material, and the front is covered by a black plastic mesh. The difference is that, compared with the angular appearance of other projectors, Mi laser projection housing is more rounded.

The side is the air outlet, and the chassis height adjuster

Bottom support

This product is supported by the bottom triangle, the middle base can not be adjusted, the two rear brackets can be adjusted by the height of the side of the screw switch, so as to achieve the product on the physical plane and a certain degree of projection image trapezoidal adjustment.

Interface area

The rear of the fuselage is the interface area of ​​the product, including three HDMI (one of which supports ARC, speakers required to connect 7.1 surround audio), a USB 3.0, 3.5mm audio output, AV interface, optical audio output, and Gigabit network mouth. In order to facilitate daily use, Xiaomi also added a USB 2.0 interface on the right side of the fuselage to facilitate the daily connection of hard disks, peripherals, and so on.

It is worth mentioning that there are two plastic baffles on the left and right of the interface area, respectively, in order to conceal the existence of the mainboard fixing screws. In fact, the product is to support the replacement of the motherboard, similar to the computer upgrade.

Due to the long life of the lens can reach more than 25,000 hours, single host and other accessories may become obsolete after a year or two, so that the cost of replacing the projection is higher, it is also more wasteful. Xiaomi said that it will launch a new motherboard in the future to facilitate user replacement. This upgrade approach is the same as the design of the millet TV split mainframe.

Projection lens

Above the fuselage is a projection lens, the left and right sides are infrared sensors. When the sensor senses a foreign object, the lens immediately reduces to a low-brightness operation, ensuring that eye damage is prevented by strong light. Below the lens is a touch light switch.

Product bottom

In addition to the three tripods at the bottom of the product, it also includes cooling holes, two audio outlet holes, and four screw holes for the installation of roof brackets. The audio uses a total of 30W of two full-range speakers and two high frequency speakers. Bass uses a low-frequency phase tube, which was commonly used in Bose's products. Although there is no subwoofer, it does not allow the sound to have no roots.

remote control

The layout of the laser theater remote control is similar to the millet TV and is also a standard 12-button design. The difference is that in addition to the white plastic that echoes the product in appearance, the circular navigation key also incorporates the "Click Wheel" wheel design similar to the Apple iPod Classic.

The Mijia Laser Theater uses an ultra-short focal concave mirror lens. When the product is close to the wall, it can project a 50-inch screen. To cast a 150-inch screen, you just need to pull the projection 50 cm away from the wall.

This product uses a large depth of field optical lens manufactured by Ricoh Japan. When the size changes within a 30-inch screen, the device is not allowed to refocus and it will not be distorted as much as other ordinary projectors.

According to official sources, the maximum brightness of the Mijia Laser Theater can reach 5000 lumens, and the static contrast ratio can reach 3000:1. Due to the time rush and the use of professional equipment to verify the accuracy of the above data, we use some test charts to test the image quality. Note that the following is to simulate the daily use environment, not the laboratory test environment.

The test environment is during the day. Turn off the lights and pull the curtains. Projection screen size is about 50 inches.

Compared

First of all, as can be seen in the figure above, the image content can be clearly discerned when the fluorescent light is turned on, but the image quality effect is affected.

image

Turn off the lights and use the test video. You can find bright colors, visual feelings and ordinary LCD TVs are quite bright, especially the red performance.

Resolution

Using Professor Qian's test chart, it is not problematic to reach FullHD in terms of clarity.

reduction

reduction

On the contrast gray scale, the problem of poor detail in dark parts is exposed. In the shadow test chart, the level of the lower left shadow was about 14 at this size, and there is still a gap between the 8 and the 8 levels. And if the screen size is adjusted to 150 inches, the dark details will drop to the standard of 16 or even 18.

Color performance

Color performance

The accuracy of the color reproduction above the expectations, except for the slight deviation of the green and yellow, the other basically accurate. This performance even surpassed many flagship LCD TVs.

Here are a few landscape maps to test the quality of the laser cinema.

Color performance

First of all, this sunset, the color between the excessive gentle, no faults.

Color performance

Fruit test chart, the difference between red and green is obvious, this performance is stronger than the ordinary projector, but there is still a gap with the LCD screen.

Color performance

In the test map of the sky, the loss of dark details is more serious. In many places only stars are visible, and the details of the surrounding nebula are lost.

Signal test

From the above figure, the input signal delay is about 88ms.

Game testing

Connecting to a PS4 game console does not cause delays. Even the more accurate FPS games do not delay the game experience.

Game testing

In this backlight image, the lack of detail in the dark part is more obvious. If the picture is raised to more than 100 inches, this situation will become more apparent.

Football Test

When using soccer test videos, there is no trailing condition on the screen. However, because the product is not equipped with relevant motion compensation techniques such as MEMC, the screen is slightly incoherent when the soccer or the player moves at high speed.

Resolution

Finally, although the projection resolution is up to 1080p, the product supports H.264 and H.265-encoded 4K video resolution, and the dragging progress will not show any significant stalling.

In terms of sound effects, the built-in speakers have a clearer hierarchy and perform well for high frequencies and vocals. Although bass is not as strong as a single subwoofer, it does not suffer from bass weakness.

The system is the same as the millet TV

Mijia Laser Theater completely quoted the style of the millet TV in the software, and did not elaborate too much on the features and richness of content. This section mainly explained the differences in projector optimization.

Homepage

Pressing the remote control for a long time will pop up a quick setup menu, which mainly includes two items: focus and keystone correction.

cycle

The focus adjustment need not be described in too much detail. By using the left and right buttons, the text can be adjusted to be all around.

cycle

Keystone correction to focus on that, Mijia Laser Theater provides physical tripod adjustment and software adjustment in two ways. The correct way to use it is to reset the software trapezoidal correction, and then adjust the height of the left and right feet so that the projection screen becomes as rectangular as possible. If it can't be tuned by physical methods, go for software adjustments. Mainly because of software adjustments will sacrifice image resolution.

Settings

In addition to focus and trapezoidal correction, there are three kinds of brightness, image parameters, and projection methods.

Settings

The brightness mode is divided into three types, and the standard mode is the default mode. The viewing mode image will give priority to the accuracy of color reproduction, and the highlight mode will prioritize the brightness and contrast of the image.

Settings

The projection method can be adjusted according to the direction of the product such as the ceiling of the product.

Settings

In addition, in the Bluetooth and peripherals interface, you can see the current millet equipment that can be matched with products. At present, the accessories available for basic millet TVs can be used in laser cinemas.

to sum up

projection

It is not a day or two that projection and television have been paralyzed each other, but actually both have their own advantages. The advantages of ordinary TV are better than the quality of the picture will not be too much affected by ambient light. The advantage of the projection is that it is portable, especially if the movie theater-like large-screen experience is turned off at night, it is unmatched by the television.

For this product, in the absence of interference with the ambient light, the picture quality performance can basically be comparable to the mid-range or even high-end TV. In the case of strong light interference, although the loss of image quality is relatively serious, the problem is not significant if the content is clearly seen. Comparing with other products, it is not bad. Under the same lighting conditions, ordinary home projectors are basically invisible.

Overall, the picture quality of this product is much stronger than that of an ordinary home projector, but it still cannot resist the interference of ambient light. However, tens of thousands of devices are unable to solve the problem. It is indeed unfair to hardly solve a million or so products.

There is 1080 signal output, 150-inch, 2.5 meters outside the viewing, and there will be no obvious image grainy, but closer look, it will indeed be as clear as 4K. In general, it is enough for most people to watch TV now.

Finally, we need to emphasize that this kind of product has certain requirements for the family wall. First of all, the edges of the image above are twisted on the way. In fact, the wall surface is uneven; secondly, if there is a pattern wallpaper in front, it will greatly affect the viewing effect; again, there will be no problem for white and other light colored walls, but dark colors The projection quality of the wall surface is poor. Of course, if you want a better picture quality, you can buy a “light curtain” of light guide glass. However, as a result, the advantages of convenience will not exist.
