Before my understanding of projection equipment still stayed in the entry-level projectors in the company's conference room, the laser projection TV just launched by Mijia could throw a large 150-inch screen, and selling only 9999 yuan did attract a lot of people's attention. Also includes myself. Last weekend I found a friend who had worked at Mijia and borrowed it from a machine. After experiencing it for two days, I had a better understanding of its actual performance.
Mi laser projection TV measurements size 410 x 291 x 88mm, bare metal weight 6.8kg, white piano paint surface treatment, simple style design, for a projection TV, the overall Yan value is acceptable.
The supplied white and black remote control is driven by two 7-cell batteries and supports voice and touch operations.
The main sales of Mijia Laser Projection TV are: ultra-short focus, wall layout without wiring, 80~150 inch projection screen, ALPD 3.0 laser source technology, 1080p resolution, NTSC color gamut 80%~85%, light source brightness 5000 Lumen, 3000:1 native contrast, 25000+ hours long light source life.
Here we need to explain that the brightness of 5000 lumens under the light source is not the brightness of the projection screen that we eventually see. The actual brightness of a white wall or curtain must be discounted. The 150-inch peak brightness measured by the BM-7A tester in the Zhongguancun online evaluation article is about 1160 lumens, and the NTSC color gamut is also close to official data and can be used as a reference. If you do not want to cast as big as 150 inches, the smaller the size, the higher the brightness will be.
Question How far does the 1:150-inch projection distance need to be? How big a wall does home need to accommodate the next 150-inch screen?
The official data is that the Mi laser projection TV can shoot 150 inches from the wall when it is 50cm away from the wall. Counting the width of the product itself close to 30cm, you can either find a TV table with a width of about 1 meter, or put the TV table. Moving forward, the request is not too low.
As for the problem of how large a home wall needs to accommodate 150-inch screens, I cannot give specific data references. Mijia Laser Projection TV is flat on the TV table, and the bottom of the projected image is about 25cm higher than the projected TV itself. This part of the increased distance needs to make room. If the home conditions allow, Mijia laser projection TV can also be used hanging on the wall. In any case you want to cast a perfect 150 inches, you need a living room with enough space.
Question 2: What are the security measures?
Mijia Laser Projection TV has an infrared sensor on both sides of the lens to prevent people from looking directly at the camera. It can automatically detect objects that block the light source, and the response speed is faster.
After the obstacle is detected, the projection brightness can be reduced to a minimum to prevent the laser light source from directly touching the eyes of the person. At the same time, a prompt “Please do not look directly at the light source†pops up on the screen. This function is necessary for families with children.
Question 3: Is there any advertising on the boot?
Of course there is no advertising on the boot, but most of the built-in video resources you want to buy millet film members, then surely there are titles of advertising, and whoever is the same smart TV.
Question 4: Is there autofocus and auto picture correction?
Mijia Laser Projection TV has automatic laser focusing, but there is no automatic screen correction and manual settings are required. Before the manual correction of the software, we can perform physical correction at the bottom of the product through two circular feet with adjustable height.
There are four trapezoidal trapezoids and eight trapezoidal trapezoids in the calibration mode. It is not difficult to operate with the remote control. Of course, the premise is that the white wall or the curtain itself is relatively flat.
Automatic laser focusing experience is very good, if you are not satisfied with the accuracy of automatic adjustment can also manually fine-tune, until the four corners of the text and graphics are all clear.
Question 5: Do you want to accept the projection effect if you turn on the lights indoors or do not pull the curtains during the day?
Therefore, to obtain the best visual effects, it is still necessary to turn off the lights at night and pull the curtains during the day, especially when the sun shines directly into the room.
Question 6: Must be equipped with a curtain? What is the right curtain?
This problem I have specifically consulted the old driver of the projector @ hard brother, he said millet laser projection TV because it is ultra-short focus so the angle of incidence is very large, a little uneven wall or screen can cause picture distortion, the basic is to enlarge the pit, There will still be wavy lines around the image after correction. So either you have a very flat white wall in your home or you can step down and prepare a curtain with no folds. As you can see from the above picture, the white wall that I think is relatively flat is actually the same thing. Fortunately, I am not a Virgo.
We all know that good anti-light and light curtains have the best light absorption effect. Laser TVs need to have a good display effect when they turn on the lights at night or do not pull curtains during the day. At present, it is certainly indispensable. However, the 150-inch hard-durable screen has surpassed the price of millet laser projection TVs, and there are not many brands to choose from. Many people who buy millet products are pursuing cost-effectiveness. It is recommended to buy a 150-inch high-gain curtain with a price of around 3,000. The local tyrants in rice noodles should use anti-light curtains.
In 2014, I was lucky enough to visit the home of the famous Alienware player “Reborn Monsterâ€. He was a combination of a 60-inch wall-mounted TV and a 120-inch screen and laser projector. The TV was used to play games and watch TV programs. The projection was used to see 1080p HD movie is a good solution.
Question 7: What is the resolution and response speed of 1080p resolution? What is the decoding capability?
Due to the limited space in the room, when I was at home, the projection screen was about 120 inches. I played a 10GB 1080p HD movie. I sat down 3 meters and felt that the picture was fine. If I zoom in to 150 inches, the resolution would definitely be lower. Considering that most of the high-definition video resources we can download at the moment are still 1080p, the resolution of the Mijia Laser Projection TV is still acceptable.
Due to the limited time of experience, I did not use it to play games. The screen response speed is still not good at making evaluations. We can look at professional tests in other media. There is no need to worry about the decoding capability. Several common formats of 1080p video do not appear to be stuck or cannot be played. Higher bitrate 4K videos can also be played smoothly.
Question 8: Is there a media evaluation that body heat is not small, is it true?
The large amount of heat generated by the projection equipment is a common phenomenon. The Mijia Laser Projection TV is no exception. After a period of actual operation, it can obviously feel that the overall temperature of the room has risen. It is still very necessary to use the air conditioner in hot summer days, and it is usually best not to let the children in your family get close to it.
Question 9: Is the noise loud during operation? How is the power consumption compared to ordinary TV?
Millet Laser Projection TV is equipped with 3 large-size fans. The noise during operation is certainly inevitable. The measured value is 45dB. However, if you put a loud sound or wear a Bluetooth headset, this level of noise is almost inaudible.
Millet laser projection TV power consumption in the bright mode is stable at about 220W, 65-inch millet TV 4A power consumption is 180W, this kind of power performance is completely acceptable.
Question 10: How is the sound quality? Is there an external speaker?
Millet laser projection TV built-in high-power dual frequency + dual high-fidelity hi-fi speaker, support DOLBY, DTS dual decoding, for me this is not enough for people with low sound quality is enough, the volume is large enough, bass effect, sound The levels are good.
Mijia Laser Projection TV supports HDMI ARC, Audio Output, S/PDIF, three external sounds, and sound quality control can also create a high-end speaker system.
Bluetooth compatibility is good, two Bluetooth headsets at home can easily identify.
Question 11: Is the expansion interface sufficient?
Of course enough, if the USB on the right side of the fuselage is also a 3.0 standard.
Question 12: Is it worth buying? Can you completely replace traditional TV?
The price of 9999 yuan is obviously worth it, especially the PC party and the mobile phone party that only watch movies without watching TV. Of course, if you need 4K of this hard indicator and the budget is sufficient, you can wait and see. There will be quite a lot of competition in the second half of the year. The same type of products emerged, and it is believed that millet laser projection TV's second-generation products will also be upgraded to 4K.
Under the current technological conditions, laser projection televisions cannot completely replace traditional televisions, and large-screen screens with low prices must be selected for laser televisions. Both high-definition and conventional televisions will continue to exist for a long period of time. If so, both will buy them.

Night Indoor Lighting Effect (on) Contrast Lighting Effect (Down) on White Wall
If the projection background is a white wall or a normal curtain, I think that people who are slightly eager for quality will not be able to accept indoor lights at night or curtains during the day. The contrast becomes noticeably insufficient, and the entire screen will feel white and colorful. There is a significant loss. Our professional editors of Home Appliances Channel said that laser TVs do not pull curtains or light curtains are not yet resistant to light and hard screens. There is no difference between them and dross equipment. Of course, your request is very low and it cannot be done. Question 6: Must be equipped with a curtain? What is the right curtain?
