I still haven't figured out whether the official name of this family of laser projection products should be called "Mia House Laser Projection TV" or "Mia House Laser Projection TV 150". In theory, for an ultra-short-focus projection device that does not have a fixed screen, the projection size is only a relative concept, and is only proportional to the distance from the projection of the photographic image - the picture farther away is larger, and the nearer one is smaller. In fact, the length of the long side of the 16:9 150-inch screen is more than 3 meters. It is indeed a problem whether the family can get such a large wall to accommodate the picture. Therefore, when the Mi family uses this product in my home and office, the actual projected area is controlled at 100-120 inches. From the point of view of the fuselage, although the size is not large, the weight of the Mi laser projection TV is still beyond my expectations - 7kg does not seem to be a large number, but still allow for its compact size and simple design. I got a little snack when I started. The same volume of conventional projectors usually weighs around 3-5 kg. This extra weight is probably related to the sound system in the Mi laser projection TV body. The operation of the whole machine is very simple: place the host directly under the screen or white wall, connect the power supply with the remote control and press the boot, then everything just needs to follow the on-screen instructions. The operation of the entire system is no different from other millet TV/TV box products. The only thing that needs to be set up independently is the screen's keystone correction and electric focusing. Due to the ultra-short focal length design of 0.233:1, the large screen that surpasses my family's 100-inch projection screen can be obtained at about 50cm from the bottom of the screen. At this time, all I can do is to place the body close to the wall as much as possible and reduce the actual projected area within the trapezoidal correction. I used the EPSON TW5350 in my home and Mijia Laser Projection TV to make a comparison with the same screen: two projectors play the same picture (home of millet shop) and use a camera with a fixed exposure value to turn off the lights (all black rooms) Turn on the screen while turning on the lights (two LEDs are shot from the ceiling near the screen). On the left and right sides of the screen are the EPSON TW5350 off/on effect, and the right side is the effect of turning off/on the Mi laser projection TV. Frankly speaking, although I had been expecting the results earlier, I was actually somewhat disappointed. The contrasting EPSON TW5350 is an entry-level 3LCD projector with 2200 lumens. It can be seen that regardless of whether the light is switched or not, the screen brightness of the conventional EPSON TW5350 is still higher than that of the Mi, and more importantly, the colors of the two are also different. I chose the 3LCD rather than the DLP structure when choosing a projector for my home audio/video room. I thought the 3LCD color performance was better. The color of this EPSON TW5350 is subject to more stringent post-production tuning, so it can be based on it. In contrast, the blue part of the Mi laser projection TV looks a bit purplish. Yes, although the color gamut of the laser source is theoretically larger and Mijia also adds various color technologies to the new machine, there are actually some deviations - in fact, the entry-level laser projection is blue and purple. Common phenomenon, I also saw the same problem when using Casio's commercial laser projector earlier. In addition, you may also find that there are some distortions in the upper left corner of the screen on the right-hand Mi laser projection television. This is actually due to the unevenness of my home's projection screen. The irregularities on these curtains have little effect on the traditional projectors projected vertically from the front, but they are easily exposed to the ultra-short-focus rays that project upwards from the bottom diagonal of the curtain. So, if you are using an ultra-short-throw projector, make sure the screen/wall is flat. I later moved the Mi laser projection television from my home back to the office and directly projected it on a relatively flat white wall. There would be no such problem. In fact, the anti-light curtains specially designed for ultra-short-focus laser projectors are mostly “hard curtains†fixed on the walls instead of the scroll screens that can be rolled up and hidden in my home. This is also the reason. The Mi family has given a comparatively ambiguous 5000 lumens light source brightness indicator. I think this is actually playing a digital concept. In fact, although the ultra-short focus projector is close to the curtain, we cannot directly stare at the projector light bulb. So the so-called “light source brightness†is not as honest as the conventional standard to tell you how much your actual viewing brightness is. . According to the measured values ​​of friends in the media, the viewing brightness of Mijia Laser Projection TV is between 1200-1500 ANSI lumens, which is not as high as the laser light source projector. I also have several “screen shots†of the Mi-ray laser projection televisions that are used alone on the white walls of the office: Turning off the lights to watch the brightness is naturally OK. However, if the ambient light is brighter, the color and contrast of the screen will decrease. If this is an LED micro-projection product, I would certainly like to commend it for its brightness, but as a laser projection for positioning a higher-end flat panel television for home use, this brightness is not enough to see - the solution is to apply professional resistance. The light curtain gains brightness and reduces the effect of ambient light on the picture. In fact, I remember that at the Mi’s press conference at the end of June, there was a Mijia Laser Projector TV with a professional light curtain on the scene to play “Rainbow VI†and its vision under bright ambient light. The effect is very good. However, the current price of professional light curtains is generally higher, and the minimum price of 100 inches is also 5,000 yuan (150 inches is definitely astronomical). Whether the user is willing to sell less than 10,000 yuan of home laser projection TV Matching such a high-priced curtain is indeed a problem - although in the professional projection field, it is very common that the curtain price reaches half or more of the host price. Of course, I do not want to deny the value of the Mi laser projection TV: For example, Mijia Laser Projection TV has more than I expected sound quality. It was very difficult for me to carefully study the effect of the built-in speaker that occupies most of the weight of the body at the press conference. However, it is now possible to fully display the clear and transparent sound quality in a quiet home and office environment (the so-called Dolby Do not talk about the sound effects, for such an integrated speaker can do the basic stereo on the line). In addition, the machine is better than expected in terms of temperature and noise control. After working for half an hour continuously, the body part near the light source can still be directly touched by hand, and the heat is not obvious. The body fan has only slight wind. After half an hour of the same work, the sound of ESPON's cooling fan in my home has been quite annoying, almost to the point where it affects the viewing experience. Secondly, it is the first product to control the price of projection products with ultra-short focus + laser light source as two key technologies. This is why I was so excited and excited after the Mi conference in late June. As the famous “price butcher†in the industry, Xiaomi and Mijia once broke the unspoken rules of pricing of various product lines, and launched a product with good performance but a much lower price than the brand with a dominant position in the product line. Some people do not care about their practices and think that it is destroying the industry ecosystem, but I am supportive of this - because they are not malicious to fight the price war, but they have taken away the original price bubble of the product line. Compresses premium space, allowing product pricing to return value. The launch of Mijia's first sweeping robot has stimulated the entire sweeping robotics industry, which has forced competitors to lower their selling prices and update smarter and more efficient walking algorithms. This time, although I think that the Mi laser projection TV still has its shortcomings in brightness and color, it is still actually a new situation in the industry to open a million-dollar laser TV - after all, some higher laser television products than its parameters. Prices are generally priced at 20,000 yuan or more. Traditional projectors such as the EPSON TW5350 are incomparable in terms of light source life, boot speed, interactivity, and content. I think that the pricing of 9999 yuan makes the Mi laser projection TV a "signature" product, but it is limited by cost and positioning, and its market advantage is not yet outstanding: Comparing with flat-panel TVs, the large screen size (we calculate the actual area by 100-120 inches) can bring the visual impact that has not been extremely intense in the past, but the gap in the image quality is still obvious; Traditional projectors, although their laser light source (actually a blue laser + LED (red) hybrid light source) have the advantages of low power consumption, long life, quick start, etc., but the current market price is similar to the EPSON TW5350 is only half of it, the cost performance is more Higher; contrasting some emerging LED light source home smart projectors, Mijia's ultra-short focus is a big selling point, but its brightness and color have no obvious advantage. So, frankly, I don’t think that “laser†is the selling point of this new machine. On the contrary, it is difficult for the family to think that the placement of the projector is difficult. The user who placed the position more publicized the characteristics of "ultra-short coke" - after all, the ultra-short-focus 1080p machine in the million yuan on the market is also just one.
