This is my dream when I was a child, but it should be called a projector at that time. I still vaguely remember the scene of watching a movie in the village valley for the first time, like "Little Soldier Zhang Ga". Although the curtain has been swaying in the wind from beginning to end, and the faces of Gazi and the devil have become round and flat, it still makes me excited. It is the projection that buried a seed in my heart that night. When I was six or seven years old, I walked into the cinema for the first time in my life. The strong sense of vision completely shocked my young soul, and at the same time, it let the seed buried in my heart break out of the shell and germinate! Later, I went to school, worked, married, and had children. I never lost my childhood dream. In the past ten years, I have played with ten or so projectors and bought one DIY accessory online. Because he is not Gao Fushuai, nor can he marry Bai Fumei, he has not been able to own the luxury goods that are often tens of thousands of dollars for the time being, and most of his hands are mainly micro investment. Compared with traditional projection, micro projection is more popular in other aspects, although it is less bright; Low power consumption, long life, small and portable, intelligent system, and relatively low price. Compared with TV, the position of micro investment in ordinary families is also rising, accounting for half of the country.

Today I want to introduce to you that this home smart micro projector is from i300j of "Eagle Eye" series of BenQ, a professional projection manufacturer. It is also the first smart home micro projector released by BenQ, which uses The self-developed TTCP rapid temperature control technology controls the core temperature of the micro projector; Six glass lenses are used to solve the problem of false focus from the source, so it is called "Eagle Eye" series.

▼ At the beginning of the text, I was really a bit embarrassed. At the beginning, I couldn't help complaining about it. For trial use, it was originally based on the principle of "not soft, not black, objective and true". If there was something bad to say, it would help to improve the product. The packaging of this BenQ i300j micro investment is the most "simple" one I have ever used. If customers only look at the packaging, they will not have the impulse to understand and buy. In this era, especially for products with a sense of science and technology, the packaging does not need to be very luxurious, but it must be distinctive. It can be exquisite, connotative, artistic, or alternative. But it cannot be so "simple". To put it bluntly, "the packaging design is a failure".

▼ The so-called good product and design must impress customers at the first sight, but today's Benji i300j really failed to do so. So whether BenQ can consider changing its packaging designer to improve the visual taste of its products.

▼ The accessories of BenQ i300j are also relatively simple. The separated power supply, remote controller, remote controller charging data cable and instructions are really simple. However, since it is a projection with 3D function, I always think that a pair of 3D glasses should be equipped in the accessories as standard, so as to bring users a better and more effective use experience. Just imagine, after the user gets the 3D projection, the melon seeds and peanuts will be placed on a table, and a stack of 3D blockbusters will be made. Everything is ready. Only when the user starts up, he finds that there is no 3D glasses. At this time, we can calculate the shadow area of his heart. To do products is to do services, and to do services is to think about what users think... (Well, well, a little too much). Then to get to the point, that is the second slot of this article - the huge power supply, which is completely incompatible with the small projection posture! I don't understand. Is it difficult to design a smaller power supply? There should be no technical problem! I dare to tell you responsibly that 120 of the 100 users of this power supply will complain. Don't ask me where the other 20 came from.

▼ The appearance design of this BenQ i300j is slightly different. It is not flat and square like the general projection. Its "butt" is raised, so it is difficult to highlight its graceful figure. Hehe, in fact, it is also well intentioned. At the end of the i300j is its sound system. This design is entirely based on acoustic considerations. The rising 13 degree "sweet corner" allows users to hear more beautiful sounds. And no matter what kind of placement posture is used for projection, this design is more conducive to sound transmission. BenQ i300j is only equipped with one physical key, that is, the power key in the center, and a prompt light on both sides.




▼ As for whether this design is beautiful, it can only be spent in each eye. However, a friend with obsessive-compulsive disorder may be more difficult to accept, and he should always think about how to press its "butt" down.

▼ BenQ i300j has designed a removable lens cover at the lens, which is a considerate design. However, without the protection of the lens cover, there will always be a lot of dust on the lens over time, and the dust on the lens is not easy to clean. However, the problem arises again. If some users use the lifting and dropping mode, it will be very troublesome to switch it, so it would be better if it could be designed as automatic. On one side of the lens, those irregular small round holes are projected cooling holes. Cold air is sucked in from the side and hot air is discharged from the front, which is really considerate.

▼ With the opening of the lens cover, the "eagle eye" will appear. Many micro projectors use resin lens for cost reasons. When the internal temperature of the machine rises, the resin lens will be deformed, which will lead to the phenomenon of virtual focus soon after the projector is turned on. In order to effectively control this phenomenon, Benji i300j Six high-quality glass lenses with lower thermal expansion rate are used to solve the problem of lens deformation from the source, so that you will not be confused by the rising temperature during use.

▼ The right side of the machine is designed with a focusing ring, air inlet and power interface. In the experience, the damping of the focusing ring is not very obvious, but it is also relatively easy to control, and the accuracy of focusing is also relatively high.

▼ Because the sound system is designed at the end of the i300j, the interfaces are placed on the left side of the projection, and the compartment cover of the interface is specially designed for beauty. The lid has a certain magnetic attraction, so it is very smooth when closing the lid. In terms of interface, the i300j has two USB interfaces, one of which is 3.0; One HDMI HD interface, one set of audio input/output interfaces, one Spdif fiber output interface and a network interface. Although the interface is not rich, it is absolutely enough for micro investment. However, I personally suggest adding a set of AV interfaces. Many people still need to connect to cable TV and Zhongjiu.

▼ At the bottom of the projection, in addition to several sets of cooling holes, there are three rubber foot pads and a standard threaded hole, of which the front foot pad is adjustable.

▼ Generally, two adjustable foot pads are designed for projection, because it will be more stable. However, this base i300j only has one in the middle. Is it because of the cooling hole?

▼ Next, let's take a look at the remote control matching BenQ i300j. It is very small, with 13 button design, good appearance and feel, and built-in lithium battery ， Micro USB power supply. It has regular Android function keys, and has also designed a one button cleaning function, which is the button of the small rocket at the bottom of the remote control.






▼ Compared with traditional projection, micro projection has an incomparable advantage, that is, its mobility. As a part of building a home theater, traditional projection is too bulky and will be fixed in a fixed position for life. Micro projection is suitable for different scenes. It is small and portable and can be placed at will. It can be taken away and put there for use whenever you want, whether in the living room, bedroom, indoor or outdoor, The weight of 900g can be easily taken away even by a little girl with no strength.

▼ 215mm x 174mm x 50mm, you can put it in your bag at will and take it on a trip.

▼ At home, You can put it directly on the desk, bookcase or a shelf.

▼ You can also use a tripod for placement. If the weight is less than 2 kg, you don't have to worry about crushing the fake tripod you bought with your 30 yuan wallet.

▼ Of course, if you have a multi-functional support, you can fix it on the small bookcase or bedside table in this way, which is more convenient.



▼ If you like to use it in the bedroom, it is a good idea to nail a small shelf on the wall. I have been using it like this for a long time. The TV in the bedroom has not been turned on for a long time, and it must have great resentment against projection.

▼ The small and portable figure is very suitable for those who often travel on business and always need projection presentation. With some office software, they can store the required documents in the USB flash drive, so that a meeting can be easily completed, and they don't have to worry about the problem of no projection or computer connection.

▼ BenQ i300j has built-in customized Kuwo KTV. If you have a set of simple microphones, you can sing at home at any time.



▼ BenQ i300j can quickly identify the input source, and it is very fast and convenient to connect the computer. I have used two micro investment before, but it is too troublesome to connect to the PC, either it is not displayed, or the screen is blurred, or the resolution is not adjusted well, in short, it is very unpleasant.




▼ Relevant parameters of i300j given by CPU-Z:



▼ The test result of Anthare: 13210 points, which is not high in truth. It can be seen that its hardware configuration can only be medium, which is related to its market positioning. BenQ i300j is targeted at people who like to pursue dramas online, so its local decoding ability may be weaker. I will carry out detailed tests to explain these later.

▼ The score is right. The score of 13210 is really not ideal ：

▼ NenaMark2 test result: 41.6fps, which is medium level.


▼ In recent years, I have been playing projection, and I often play in some projection forums and QQ groups. In addition to the price and quality of the projector, the most frequently heard question is how is the brightness of a certain machine? Is calorific value high? Is the noise big? How about the power consumption and so on, while for the micro investment products using DLP technology, netizens will have more doubts, that is, whether there is a virtual focus, whether the hot engine will go out of focus, whether it is convenient to carry out and so on. Since users are paying attention to these problems, it shows that these data are relatively important for consumers. The brightness determines the display effect of the projection. Heat represents the stability of the machine. Noise and virtual focus shift directly affect the mood when watching movies. Power consumption is directly related to your wallet. Now let's go to see my attitude towards Benki i300j The test results of some relevant data, because the instruments used are not professional equipment, errors are inevitable, and the test results are only for your reference, so don't take them too seriously.
▼ [Power test] After the machine is powered on, the power is about 0 watts per hour when it is in standby mode, and about 45 watts when it is in no-load mode. When a 320G mobile hard disk is attached, the power will be about 5 watts more, floating around 50 watts, which is lower than the official 75W, which is more power saving. Through data calculation, for example, if we use 3 hours a day and the electricity is 1 yuan per kilowatt hour, the electricity consumption in 30 days a month is about 4500 watts, and the electricity cost is about 4.5 yuan. This data can save much more money than ordinary household LCD TVs.

▼ 【 Temperature test 】 We Yes, the traditional light bulb projector has always been a big fan of fever. If you watch the movie too close, you can sweat Heat has always been a key issue of concern to users, and if the volume of micro injection is too small, it will certainly affect the normal operation of the machine. that BenQ i300j How about the performance in this regard? Come and have a look with me!
The starting time of the machine is about 4 hours. The temperature measuring gun and the machine shadow machine have been placed in the same environment for 3 hours. At this time, the indoor ambient temperature is only 2 degrees. According to the infrared temperature measuring gun test, most of the temperature on the machine surface is about 12 degrees, and some of the positions are lower than 6 degrees. I took the temperature data inside the machine cooling hole, and the maximum is 39.3 degrees. This data may be slightly different due to the low ambient temperature, but we can still see from it BenQ i300j The heat dissipation is very good.

▼ [Noise test] For projectors, noise is also a concern of many friends, because it will not only affect the mood of users when watching movies, but also may damage users' hearing due to loud noise. Let's first take a look at the difference between noise and ordinary people:
0 - 20 decibels: basically not felt at this level.
20-40 dB: Quiet, like whispering.
40-60 dB: Ordinary, ordinary indoor conversation.
60-70 dB: noisy, nerve damaging;
70-90 decibels: very noisy, nerve cells are damaged.
90-100 dB: increased noise and hearing loss;
100-120 decibels: unbearable, temporary deafness after one minute.
Above 120 decibels: extremely deaf or totally deaf.
Because the professional test noise is carried out in an absolutely silent space, the data obtained in that way is more accurate, of course, I can't do it. What I can do is to choose a relatively quiet environment. The test time is at 1 a.m., and the surrounding area is still relatively quiet. At this time, the ambient noise is 34.6 decibels. In order to achieve the relative accuracy of the data, I used a more common noise test technique - five directional fixed-point test method as before. That is to say, the same distance of 50CM is used to sample the data in the front, back, left and right directions of the measured object, and then the five data are averaged to obtain a relatively accurate result. From the figure below, we can see that the values in the five directions are 37.7, 37.1, 38.6, 37.2 and 38.9 respectively, so the average value is 37.9dB, which is slightly higher than the official 30dB.
（ The test mode is general mode, and the noise may rise or fall slightly in other modes, but the frequency of use is not high, so we will not test one by one. ）

▼ [Brightness test] I believe that for projection, brightness has always been one of the indicators most concerned by users. Here I remind you that the high brightness of commercial projection is to meet the needs of business office use in the daytime, while most of the home projection is used at night, and most of them are used in full darkness. So, Too high brightness will hurt your glasses, so I also advise you that if you don't have special needs, you don't need too high brightness at home. Of course, some friends who like watching TV by projection in the daytime can ignore my words. Since the indicator of brightness will greatly affect the user's choice when purchasing, basically all projection manufacturers will deliberately raise the lumen of the machine in the propaganda. We are used to this, so let's take a test together BenQ i300j What is the true brightness of!
In order to test more accurately, I used the ANSI 9-point test method, that is, to measure the illuminance of 9 points in the picture, and then the average illuminance of 9 points is the average illuminance of the whole screen, and then multiplied by the picture size to get the brightness of the machine, that is, the lumen number. The lux values of the nine points are 367lux, 385lux, 349lux, 400lux, 402lux, 370lux, 415lux, 410lux, 384lux, with an average value of about 387, and then multiplied by the area of 0.816 (120 wide, 68 high) to obtain the ANSI brightness of 316 lumens. This value is also close to the official 400 lumens. It must be clear The i300j uses ISO lumens, which are different in measurement methods and environmental requirements, and some discrepancies are normal. and The brightness of some projection manufacturers is actually based on the peak brightness of the projection, Peak brightness refers to the highest brightness that a single point can reach under the brightest mode.
（ The brightness is tested in the standard mode, which is the most commonly used and the effect is relatively ideal. ）

▼ [Virtual focus test] I have used many micro projectors before, and basically all have one thing in common, that is, the focal length is clearly adjusted when starting up, and it becomes blurred after ten minutes, and needs to be adjusted again. However, this is not over. When you start up again the next day, it needs to be adjusted again. When the machine is hot, it needs to be adjusted again and again... Why, Because most micro projectors use resin lens for cost consideration, and the resin lens will deform at high temperature, so the phenomenon of thermal defocus occurs. So BenQ The reason why the i300j is called "eagle eye" is that it uses six glass lenses to optimize heat flow processing, so that the micro projector can achieve thermal engine without virtual focus. After testing, BenQ The i300j does achieve this, and there is no false focus after the hot engine.

▼ However, it is not perfect. Although there is no virtual focus after the hot engine, the entire screen cannot be adjusted to be all clear, and the upper right corner is always a little blurry than the other three corners.


▼ We know that as the projection distance increases, the brightness will gradually decline, and the picture quality will become worse and worse. Therefore, the brightness has a great relationship with the size and effect of the projection. From the previous chapter, we measured BenQ i300j Of ANSI brightness is 316 lumens, how will it perform in terms of projection size and display effect? Let me uncover the mystery for everyone!
In terms of projection size, the official data is 80 inches for 2.4 meters. After testing, BenQ i300j It takes 3.2 meters to project a 100 inch picture. Although it is said that BenQ The i300j can project 40-200 pictures, but The picture quality will decline significantly after it exceeds 120 inches, and the best effect can be achieved between 80 inches and 100 inches, taking into account the picture quality and the large screen. At 120 inch, although the picture quality has declined, it is still within the acceptable range, and the visual impact effect will increase.



▼ Due to the equipment, environment and technical level, it is certainly impossible to restore the display effect to everyone in screen photography, but it can only be relatively close to the actual effect as far as possible.



▼ Let's have a look BenQ The contrast effect between i300j and a LCD TV and the original picture can be seen from the following two comparison pictures, BenQ The i300j is more realistic in color reproduction, while the LCD TV has higher sharpness and cooler colors. by comparison, BenQ The i300j displays better.

▼ As the model name of "Eagle Eye", BenQ i300 is actually divided into two models according to channels. The i300T represents Tmall model, while the i300J I got represents JD model. It is not difficult to see from its main interface that there is a sign of "JD+" on the top left of the screen. BenQ I300j as a model , Android 4.4 system is built in, and the blocky UI design lacks a little personalization. The main interface is divided into four parts: "recommendation", "classification", "application" and settings.

▼ BenQ I300j's online video content partner is Youpeng Pule, which contains a large number of legitimate video resources. The classification is also quite detailed, and the operation is extremely convenient.

▼ As an intelligent projection, BenQ i300j can install a large number of software programs at will. In the application interface, we can add them to the desktop according to our own preferences for easy use at any time.

▼ In the setting interface, BenQ i300j abandons the Android native setting interface and specially customizes its own interface, which is simpler and faster.








▼ BenQ i300j supports Bluetooth function, that is, it can connect with all flying mice, keyboards, game consoles, headsets, and audio devices with Bluetooth function, which greatly facilitates our subsequent use.

▼ BenQ i300j supports online network upgrade, eliminating the trouble of downloading and copying.


▼ As I said earlier, BenQ i300j is positioned at home entertainment intelligent micro investment, and the main target audience is those consumers who like to chase dramas and watch movies online. Therefore, it has made great efforts in online resources. Its content provider is Youpeng Pule, which has a large number of legitimate film and television resources, and is relatively powerful in updating speed, Many TV plays that are being shown on satellite TV can also be found here. But the only thing that makes me dissatisfied is that many of its resources are charged, which is too inconsistent with the spirit of free sharing on the Internet. Of course, there is a reason for charging fees. People have copyrights! Well, this reason still can't convince me. I still don't like to watch movies and TV plays for a fee.

▼ The film classification is quite detailed. You can also find "Young Marshal" and "The Wrong Train" on the air.

▼ In terms of movies, there may be high requirements and many copyright issues, so I haven't seen any of the recent films.



▼ Screen shot of stills:



▼ There are a lot of films that need to be paid. To be honest, they are not new films. They are old films and can be seen everywhere. They even charge 5 yuan for one time. I wonder if someone will really pay for them.

▼ The charging standard is really not cheap, 30 yuan per month.

▼ When I was talking about the charges for movies, I suddenly found that there are still benefits. You can add the public account to get the annual card for free. It's a lucky egg! The method is also relatively simple. Just follow the prompts on the screen. Soon, after one year of membership, you can finally watch one year of free movies, saving 360 oceans. It's really exciting to think about it.



▼ Of course, if you don't care about this charging online platform, there are a lot of other free ones. I won't list them one by one. Download them in the next market!




▼ I said in the software scoring link, BenQ i300j is mainly online, and the local play will not be very good. Now I have tested it, and sure enough, it is not ideal. First, I used Anthare's video test. Three of the 30 video samples do not support it, 10 have problems, and only 17 can play normally. At present, such local broadcasting level should be among the middle and lower levels.

▼ Properties of 17 samples played normally:

▼ Ten sample attributes with playback problems either do not support audio format or are stuck.

▼ Three unsupported video formats:

▼ Although knowing that local play is not BenQ i300j's strong points, and I basically understood its decoding ability in the software test, but I still tried to play some conventional test films, including 4K, 1080P, 720P, H.265 encoding, etc. The whole army of the 4K series was killed. Because DTS and AC3 audio formats are not supported, all 1080P samples have no sound, and the playback is not smooth. A small part of the H.265 code can be played normally, and others cannot be decoded. Basically, the films that can be viewed normally are in the ordinary 720P format, which is more consistent with its positioning.







▼ So if you are keen on local high-definition movies, then you are selling this Before BenQ i300j, you must consider clearly, or add another one Anyway, the price of cabbage is very affordable.


▼ BenQ i300j supports active 3D playback, and the effect is very good. There is no flickering and blurred screen during the experience. Some demos with good screen effect can definitely bring you a sense of immersive experience. Unlike most 3D projections, BenQ i300j does not set 3D buttons on the remote control, nor does it mark 3D functions on the body and outer package. People who do not know it well may not know that it is a 3D projection. To switch 3D, you need to enter the 3D menu by setting.


▼ Personally, I prefer to watch 3D movies, which is a three-dimensional feeling that 2D movies can't give. Before, I had to go to the cinema to see some classic 3D movies, and the effect was absolutely excellent. As for movie tickets, we are a small city in the eighth tier, and the price is not expensive, which is acceptable, but we can't stare at each other every time we go to see them, and we also need to buy something delicious, After watching the movie, we have to have a meal. After a movie for two people, at least 200 yuan will be spent, which is still a bit painful. Now with 3D projection, although the effect is certainly not comparable to that of cinemas, cinemas certainly cannot give privacy, and some 3D films cannot be seen in cinemas, you know. So I don't go to the cinema much now. Anyway, I'm not in a hurry to watch it. After a while, there will be downloads on the Internet.




▼ In terms of games The remote control of BenQ i300j does not have the function of flying mouse, so it can only play some relatively simple games. Fortunately, it supports Bluetooth function, so if you have a game controller with Bluetooth function, it will be very different.

▼ As a post-80s generation, what I like most is these arcade games that have hindered my countless studies. Although it is said that this kind of game is the most enjoyable to play with a joystick, it has a different excitement with a handle and a 100 inch screen. Of course, if you have a higher pursuit, you can connect the PS4, XBOX360 or PC to play large games, which will naturally feel better.






advantage:
1. The design of the body is small and fashionable, with strong portability.
2. It supports one button power on and two button power off, which is particularly convenient 。
3. Support active 3D with excellent playback effect.
4. 5.1 channel output, dual 8W speakers, and 13 degree "sweet corner" bring ideal sound quality.
5、 The important indicators of power consumption, temperature, brightness and noise are very ideal.
6、 The machine adopts glass lens, and the phenomenon of virtual focus and out of focus has been well controlled during use.
7. With lens cover, it can effectively prevent dust.
8、 Long life LED light source, saving subsequent expenses.
9. Bluetooth function is supported.

Disadvantages:
1. The remote control does not support mouse mode, and some software cannot operate smoothly.
2. The power supply is too large and inconvenient.
3. The packing is too simple.
4. The hardware configuration is general, and the local playback ability is not ideal.
5. The built-in online video platform charges.

Conclusion: This BenQ i300j household intelligent micro investment is very good in quality. It must be a product made by a professional manufacturer, but it still lacks in packaging design and appearance design. The name of "eagle eye" is really rich, but the hardware configuration is slightly low, and local playback is not ideal. The remote control is indeed very convenient in some operations, but it does not have the function of flying mouse, which makes it difficult to start in many applications. In general, it is a very good micro investment product, and I believe that it will be more perfect with subsequent efforts.
