On August 27th, we saw the product reservation information pushed by SMZDM website: Nut Home Theater (RMB 1999) (Open Appointment), a grass in my heart (buy a LED projector) suddenly sprouted, and he decided not to hesitate without hesitation. (Hey, to beat the rhythm...)
I'm not a videophile. Although I have LCD TVs and 3LCD projectors, I'm an enthusiast of electronics. (In fact, I'm buying new electronic products all day long. ). For projection, currently divided according to the display device, the common is nothing more than 3LCD and DLP, the former 3LCD panel is the technology mastered by the Japanese, is characterized by three primary colors synthetic image, accurate color reproduction, especially the human skin color, which is the display technology The hard part is that it best shows the accuracy of color, because the color of a person's skin is accurate and can be seen by one eye at a glance. Big names include EPSON, SHARP, SONY, Mitsubishi, NEC. . .
The latter DLP panel technology is dominated by the old Texas Instruments, a single device produced by semiconductor technology, the structure is simple (relative to 3LCD), the technology is mature, the performance is reliable, the color can only be said to be quite satisfactory, the price of course will be a lot of benefits, So DLP is currently the mainstream, Optoma, BenQ, Acer, these manufacturers are basically the DLP camp, the projector can reach the price of 2,000 yuan, DLP contributed.
In addition to the panel, the projector can also be distinguished from the projection light source technology. Commonly used traditional high-voltage, high-bright bulbs and emerging LED light sources, in addition to laser light source technology, are dominated by companies such as Hitachi and Sony. Although the display effect is very outstanding, but the cost is not high, so the market is very rare. The mainstream or light bulb as a light source projector, occupying the vast majority of the market.
High-voltage light bulbs have been used as projection light sources for several decades. Its advantages are high brightness, simple structure, and reliable performance. Disadvantages are high energy consumption, large heat generation, fast brightness decay, large volume of light sources, and large space and device for heat dissipation. , so the traditional projector with high pressure lamp has a difficult problem that can not be bypassed is large, large noise, the cost of replacing the light source later, the current mainstream projector lamp life is 2000-3000 hours, if you sacrifice the brightness, turn on energy Mode for longer use time, the light bulb can also be used to claim 5000-6000 hours, but once the brightness is attenuated to the extent of replacement, the price of a Japanese brand original light bulb must be 2,000 yuan, the Taiwan Department brand is About 1,000 yuan, this is a large post-expenditure. In addition to this power consumption and heat dissipation is a major problem around the traditional light source projection, in addition to the technology to update the light bulb brightness, the other is the input must be large, the power consumption will also be large, the light bulb's heat will also rise, the heat is not Exhausting the inside of the machine, the machine will be overheated, the image light bulb and the life of the machine, so the heat dissipation is very good and very strong, so the problem of wind noise is an inevitable problem. The projector of the traditional light source is a whirring call. Hot air heaters are by no means worthless!
Although traditional light source projection is a big fan of heat and short life, but for decades this technology has been optimized, used, and optimized to thousands of hours of high-brightness work, but all of this will eventually be a new light source technology. Innovation, just this one, is for many years! Laser hybrid light source technology and LED light source technology are beginning to emerge, and at present, the application and promotion of LED light source technology is the leading one (note, not that technology is leading, but cost-effective, just like non-professionals are cheap enough to use) Because LED technology is developing very fast these past years, LED industry giants such as Japan Daily Chemical, Philips of the Netherlands, and Osram of Germany have continuously broken through the bottleneck of color, brightness, chroma, and power consumption in the industry, so LED light sources slowly Applications in flashlights, small spotlights and other small applications slowly climbed the scene of street lighting, automotive lighting and other high-brightness, low-power applications. The projector's LED light source came into being at this time!
LED light source has a great advantage of low power consumption, high brightness, good color purity, which means that use it as a light source, consumes less power, compared to the original power consumption of more than 200 watts of the traditional light bulb projection maneuver, LED light source To be less than half or more; low power consumption means less heat, less heat means that the temperature of the display device's work area can be reduced a lot, the temperature requirements of the device is not so harsh, which is also good for the stability of the device's work Less heat also means that the heat sink components do not need to be as powerful as the original ones, and the fans can be made lighter than the original design, and the air volume can also be smaller. In the past, the sounds of snoring and the heat waves have become history.
A product will appear because the industry has all the weather, geographical conditions, human and conditions, when the display device DLP hit the Osram Q7 light source, a product such as nuts came into being. I have been concerned about projection has been for many years, and even myself have a DIY, although successful, but the effect is too bad, throw thousands of pieces, when it is practiced hands, enjoy hands-on fun, and later bought a SONY 3LCD projection basic income Hands, but the concern is continuous, because I see the rise of LED and laser light source, did not start because of the price, it is still too high!
The process of placing orders on the machine is still very smooth (outbreak of personality!? If there is no appointment, is it not for me to give up, save money for me...), Shunfeng is also very reliable. . . Unexpectedly on the third day from Shenzhen to Suzhou (road transport, normal it), I just signed for work on the express, and hey, not to work ah, want to sneak away home. . . So this goods, it's not good to come early, come late, go to the streets (by, what quality do I have.)
There are two layers of packaging, and the outside is a corrugated box for transportation, and the size of the inner box fits well.
Inside is the product packaging, white and orange. There is a mango TV, this mark shows that it is still a bit of content drops. . . The source of the program is a rare thing recently. Do you not know that online video is playing hard? You say fast broadcast? Hehehehe, I don't know. . .
Open the package. . . After installation, the internal products are displayed in an orderly manner, and the certificate first comes into view; the white host is wrapped at both ends of the foam cushion, which is more stringent; the accessories power cord, USB cable, warranty card and manual are scattered in the plastic bag; the overall display package is still More reliable, long-distance motor transport problems. Various details are as follows:
The boot, scared by the size of the picture, I was less than 3 meters cast white wall, my half wall has been covered, an estimated 140 inches? ! Because there is no rotary adjustment ring to adjust the lens distance, only the focus adjustment ring, so the projector pushed forward more than half a meter, close to 100 inches or less, I think the screen is big enough.
Then set your own wireless network, enter your own WIFI password, connect quickly, no exceptions.
Next set Bluetooth, I use the Bluetooth speaker to play the sound, so do not need to connect any cable, but also a successful match, the projector has Bluetooth, this feature is really useful!
Then I looked at the brightness and contrast. I felt that the brightness could be increased by one octave. Others were not suitable for tune, because the individual feels to adjust the picture even worse.
I then went to Mango TV to see if the network was connected successfully and if the content page could be accessed, the result went smoothly.
At this time the daughter can not wait to play her weekend movie, Barbie movie, or else on this machine, copy the 1080P MKV to the TF memory card, insert the machine, complete playback, midway I also chose the Chinese screen (I think The machine may not be able to choose), I feel that this local player software is still relying on spectrum drops, it seems to see a small movie or something, my millet box will not have to plug in this machine. . .
This morning I got up and installed it with a sofa TV, TaiJie video and other applications. It is currently being tested. In the morning, the light in the room was not strong. I watched the Oriental News. I couldn't pull the curtains to see the program clearly, so the brightness was good.
Do not pull the curtains during the day:
The overall feeling of this machine brightness is really good (in terms of energy-saving LED light source), the function is relatively complete, although it is a new product with functional integration, or is still in the engineering machine stage, but the current complete degree of the machine has been very good, the set-top box The solution, OSRAM LED light source and DLP display device were integrated into such a small, beautiful white box, and it became a good product for 1999 yuan, which was quite good. Although the color and my 3LCD projection were very different, it was because of the light source and display device. Differently, such comparisons are unfair.
It took a few days to find some bugs or areas to be improved, such as Bluetooth sound can only accept the sound sent by the Android software, external HDMI sound can not be transmitted via Bluetooth, can only be put in the speaker on the machine; projector The lens is relatively general, no coating, so the degree of color reproduction is lacking; normal boot default energy-saving mode, after closing the energy-saving mode cooling fan will work at full capacity, resulting in a lot of noise all at once; the player software, some video files are not Can correctly identify. . . These may be because this is the cause of the engineering machine. The official machine seems to be on the market tomorrow. Manufacturers say that there will be a lot of improvement, and the engineering machine users can achieve a certain number of points to replace the official version of the machine. (Forum points up to 1000 Nuts, I've reached it now, oh...) Let's wait and see!
