Foreword
Speaking of projectors, we often think of issues such as whether their high selling prices are practical or not. In the development of projection for so many years, the use of family has not been popularized. This also shows that projection is not necessary for most of us. Most people who buy projectors are people who love movies and they are also one. The people who will enjoy are still extravagant people. Why should I say this? It's because the movie still has to go to the cinema to have a feeling. It doesn't feel that shocking on a TV or a computer, but a lot of movie theaters do not, so we can only use the projector. To achieve this feeling, in fact, the movie played in the cinema is also completed by the projector, but it is more expensive and more professional. When the projection is connected with the audio, it is a cinematic enjoyment. When you bought the projector, you just wanted to enjoy the feeling. It turned out to be really good.
First purchase experience
-------------------------------------------------- ----------------------------------------
Projection I probably started contact in 2008 and bought the first projector in 2009. At that time, it was a hot-blooded young person who bought projections for watching movies. At that time, home projectors were still very few, and few people would buy projectors to watch movies at home, unless those who like me to pursue visual and auditory shock, feel that it is a kind of enjoyment of friends. But this kind of enjoyment is generally played by rich people. I can only hope to enjoy the ocean and sigh. At that time, the light bought projections for two months of salary (fortunately, no girlfriend), not to mention the sound. Before you buy, you must first soak the forum for research, and then make a variety of comparisons. The final choice is a version of Optoma, more than 4,000 pieces. The market is also considered very cheap, and the biggest reason is still in terms of price. However, when you bought anything, you said it well. The Optoma's profiteer finally said that it was now out of stock. Let me get the prototype back first. I was angry, and you told me a piece of yarn. What happened to the prototype? do? Later, he directly went to the opposite side of his home to buy Lenovo (the same parameters under the lower price point), but did not expect that in less than a year Lenovo would withdraw from the projector market really sad. This is my first purchase experience, or it is relatively unsuccessful. The old driver will not say anything. If a newcomer buys something, he or she is the best person to understand. In this regard, he will know more about the brand and after-sale at a certain price. Still very important.
Test product
-------------------------------------------------- -----------------------------------------
The projection of this test is the BenQ i300J Hawkeye micro-projection. BenQ is also considered to be the big brother in the projection industry, and the past glory needless to say, the status in the traditional projection field is unshakable, but BenQ can be said to be a novice in the field of intelligent micro-projection. For smart microprojectors, hardware capabilities are only one aspect, easier to use operation methods, more program resources, better playback effects, and more adaptable environments are also the most important aspect of intelligent microprojection. BenQ can be said to be a late start in this area, but also recently began to force the field of intelligent projection, this time the i300J Hawkeye micro-projection can be said BenQ this type of entry-level projection, for this projection, we still first Maintain a questionable attitude to evaluate and see if BenQ can still maintain its original quality in the field of miniature projection.

Unpacking and Touring
-------------------------------------------------- -----------------------------------------
Excitedly excited to open the express package to see the projector's box, the feeling is still somewhat disappointed, packaging and design are very simple, no sense of high-end, is BenQ too low-key.
The whole box has only the model number and basic data of the product written on a sticker, and the labeling of the sale item does not know whether it is an engineering machine or not, and it is hoped that the retail version of the packaging will be better.
The box inside can be extracted from the side.
Inside the packaging is also very simple, the middle is the host, the left is the power cord and a charging line, the right side is the remote control and power supply.
All accessories include remote control, power cord, charging cable, manual, three packs of cards, and remote control. It should be noted here that the official host and remote control warranty is two years, and the light bulb is six months or less than 1,000 hours (online inquiry).
The regulated power supply is manufactured by Great Wall,
The remote control is small and the layout is simple and easy to use, but the workmanship and design look shabby. The top hole is the charge indicator, and the bottom left is the source switch menu, power button, and menu button. In the middle is the navigation and confirmation keys. Here is the return, homepage, and media player menus. What is not marked is a reserved function button. At the bottom is a one-touch accelerator.
The built-in lithium battery of the remote controller uses the Micro USB interface for charging. When the battery is not available, it can be plugged in to the mobile power supply for power supply operation. It is very convenient. There is a lanyard hole at the top, which can be easily hung for an accessory or hand ring.
The first time you use the remote control for pairing, but it is directly available when you get the machine switched on.
The instructions are illustrated in color drawings. They can be understood at a glance and are easy to use.
Most of the hosts use Champagne Gold, and the tail color is similar to that of local gold. It still looks harmonious. The overall appearance of the design is still very simple, does not give a kind of bright feeling, it is quite satisfactory. The overall appearance of the work is still somewhat rough, and some of the gaps are not as good as BenQ's traditional projections. If you don't stick with BenQ, there is still a cheap feeling.
The front center position is where the power button is also the indicator light. The left side is the temperature LED and the right is the LED.
The lens is forbidden to directly use the eyes to watch the lens of the boot. This is still very intimate.
The projection of the butt from the side is tilted up, and this is one of the highlights of this projector's design. Of course, this design is not just for the sake of good looks. The official propaganda is a design with a 13-degree angle to the horizontal plane, so that whether sitting or standing can obtain a larger listening area. The leftmost hole is the power cable jack. The lower center of the hole is the vent and the far right is the focus ring.
The BenQ i300J is manually focussed and the damping is still very good when used. Subtle adjustments are also very easy. Saying that such manual adjustment is still inconvenient, if you can design to the remote control is even better.
The left side is the location of various interfaces, using a hidden design, open the lid to see these interfaces. I300J can see the interface is still very complete, from left to right is followed by USB3.0, HDMI input, headphone output, microphone input, USB2.0, SPDIF output, Network Cable interface.
The front is the lens and vent position. This vent is still relatively large.
The lens cover can be opened by sliding directly. This lens is the main eagle lens of this projector. It uses LED light source and 6 glass optical lens groups. The purpose of using glass lens is to prevent the lens from overheating and produce the problem of virtual focus. This is also the same type and the same market positioning. The difference of the machine. In addition to changes in the hardware, we also use the self-developed high-speed temperature control technology to assist, the combination of the two to achieve a better display, bid farewell to the occurrence of coke and virtual coke.
The entire tail is the location of the speaker, and it seems that the position occupied by the speaker is still relatively large. With two generating units, the general mini-projector has such a small number of speakers, and the left and right channels make the dialogue and sound effects have a good sense of hierarchy. Bluetooth speakers can also be used. From the audio rear position, BenQ can also see this projection positioned on the desktop, after all, we can fully feel the impact of the sound on the back of the projector.
There are three feet on the bottom of the fuselage, which can be adjusted in height. The round hole between the two rear triangle pads is the tripod mount hole. When I first started using it, I always felt that the left side of the body was a bit low. I thought it was the reason for the desktop, but I changed it a few times and it was the same problem. Then I took a closer look and the original adjustment pad was not in the middle of the front end. , biased to the right of the fuselage some, perhaps because of the internal structure of the reason, but this design still brings some inconvenience, if you can make two in the three feet can be adjusted will be better.
The bottom of the cooling holes are basically distributed in the main heat, the bottom of the design can play a role in dust protection.
The official figure can also see the work of the host cooling, the machine embedded temperature sensor sensor, real-time monitoring of temperature, adjust the fan speed, how the abnormal temperature of the front of the machine TEMP indicator will light, and add the graphite layer , better heat conduction. The approximate structure of the speakers can also be seen in this picture. Even the design of the unit looks good.
Adjust the foot pad can be removed, the thread part is a piece of white plastic, basically screwed to the maximum including the plastic part is 1.5CM, screw to cover the white plastic part is about 0.7CM (not counting the protruding part of the pad) .
operating
-------------------------------------------------- -----------------------------------------
Only a short press of the power button will start the projection and the indicator will turn green when activated.
The first time you turn on the system, you will be prompted with the most basic settings for the projection, similar to the smartphone. The design of this machine is still the most suitable desktop projection.
The basic interface of the system is similar to those of smart boxes and smart TVs. People who have used similar devices can easily get started. The upper left corner can be seen as a collaboration between BenQ, JD.com and the Octagon. The resources of the movie are still somewhat old. Generally, the system resources that come with such devices are updated slowly.
With its own store, it can be downloaded and used freely. It is generally used for downloading third-party movie and TV APPs. Many new movies are available.
This projection also has a feature is to have a customized version of cool I K song, support for 5.1 channels, of course, the projector itself is also possible, but certainly no professional speakers better, but at home K song is afraid it will be Let's die.
The system setup is very simple and is based on Android 4.4.4. The configuration is much lower than that of a cell phone, but it is more than enough to project this device.
The Bluetooth connection can connect to the mobile phone, but it cannot use the mobile phone for music playback and other functions. It can only transfer some file content. You can use projection to connect Bluetooth speakers, connectivity is still possible.
In addition to the system settings, the projection of your own settings is also relatively simple, the basic brightness, contrast, image mode, color temperature, sound mode, picture ratio, etc. can be easily set. Tucao here is the volume adjustment function, the volume size on the remote control can not be adjusted directly, you can only press the remote menu key to exhale the setting menu (above) to select the volume to be able to adjust, this design is really very Failed, I started looking for a long time on the remote control. It was really anti-human design. If it was the night we began to watch movies, especially when we watch shy movies, if the volume is too loud, then we will be too busy. of.
Also supports 3D mode, support up and down and left and right 3D viewing mode, but personal advice to see 3D or direct download 3D film source, the best resources to download directly from the kind of film 3D shooting point of view, such as "Avatar †Later conversion is a money-making movie.
You can also set language and location. Trapezoidal correction can be selected automatically and manually, but only the upper and lower trapezoidal correction can not be left and right settings, this is still a little regrettable. You can also set the automatic shutdown time, and you can worry about sleeping at night. LED mode can choose normal and power saving mode, power saving mode will reduce the brightness of the bulb, but also increase the life of the bulb, but it will sound a certain viewing effect, which depends on their own choice, and now the domestic theaters are generally It is to reduce the projection brightness to achieve the purpose of reducing costs, so that we will be more tired when watching glasses, especially when watching 3D movies more tired.
The entire system feels the most convenient and easy to use function or the one-click acceleration clearing key and source switching key on the remote control. Smart devices use smart systems first, then closing the background program will also make the system run smoothly. Remote control is very convenient when using clean keys. The source can choose HDMI input, USB function, mirroring function. HDMI input can connect to the PC. When the monitor is used, playing large games is still cool.
When the surrounding environment is quiet, the noise is basically kept at around 45dB, or it can be accepted. When using projection to watch the content of the movie, the noise can be ignored directly, and the viewing effect is not affected.
Experience
-------------------------------------------------- -----------------------------------------
Use of the environment: the living room
Projection objects: glass bead curtain, white wall surface
Curtain size: 100 inches
Curtain ratio: 4:3
Advice from people: When I bought projections, I paid for the sound, and finally I got a 5.1 channel soundtrack (not a good one). The sound is too expensive, and you have to get a minimum of tens of thousands. Afterwards, if you study the placement of audio, it is also a tossing period of time. Everyone who wants to have good conditions at home must have a free one. If you have a special radiography room in your house (think at the time), you can go to some of the professional teams. The computer city or the place where you sell the projector will do it for you. Although they are expensive, they will have room layout, sound insulation and sound. Position, curtain customization and other aspects of the design, at the time of experience in the computer city, really good, but it is really expensive, you have money, hesitate. But the ideal is very full, the reality is very skinny, most people do not have so much money like me, get this, then select the sound, the curtain of these things on the right, and spend some time on their own requirements of this will not It was very high. My reason was that because of many reasons, the sound system and the ash were on the sidelines. At night, sometimes even the curtains were too lazy to use.
The distance from the wall to the front of the coffee table is about three meters. The curtain is 100 inches. The entire screen has exceeded the size of the screen. The official introduction is that the 2.4 meters can be 80 inches. The i300J is a fixed-focus projector, so if you want to use the screen, you have to adjust the position of the projector, either to find a stool to move forward or to move the coffee table forward, which is really inconvenient.
A smart projector does not have a dedicated mobile app. It always feels something missing. The i300J only supports the transmission of the phone image to the projector for feedback (provided that the mobile phone has a wireless display capability). The phone cannot display the projector at the same time. System screen operation. However, fortunately, the transmission of the video basically kept in sync and it was very smooth when playing games.
â– In vitro: About the curtain
When it comes to experience, say the effect of the curtain on projection. In addition to the capabilities of the projector itself, choosing different curtains may be different for actual results. Because the curtain itself is also reflective. The curtains commonly used in the market include gray screens, white plastic screens, glass bead screens, and metal screens. Of course there are others, but these are the more common curtains. In fact, we must talk about the curtain, and the content is still relatively many. Here is a brief explanation, and people who are not familiar with it can understand it.
Gray screen: personal favorite, see the contrast of the movie to force, I use projection is mainly to watch movies.
White plastic screen: The viewing angle is large, and it looks similar in that position.
Glass bead curtain: the direction of the right is bright, the viewing angle is small, and the price is cheap.
Metal curtain: the combination of white plastic and glass beads. The price is also more expensive.
The choice of the curtain depends on personal preferences and economic conditions. After all, the screen size is relatively large. I chose the bead curtain for economic reasons. If I choose, I will definitely choose the gray curtain.
This is a contrast effect that is thrown on the bead screens and walls, but it does not seem that the gap is large. The glass bead curtains, though cheap, will be somewhat yellowish when used for a long time. If it is at night to use a white wall is also possible, but it is not recommended to allow the wall to replace the curtain, if the external light is strong, then the wall display will be much worse.
Turn off the projection of all lights at night. For the projector, lumens and resolution are very important parameters. The BenQ i300J's standard resolution is 1280 x 800 (maximum support 16001200), although not reach a higher 2K resolution, but generally we consider the reason for the projection distance and then the effect of high resolution looks not very obvious. After all, the resolution of a movie theater projector generally requires 2K or higher. BenQ is considered practical and no more gimmicks at this point.
This is the effect of displaying the front light, middle light, rear light at different positions, cold light and warm light. It can be seen that the effect of casting in strong light is normal, and surely no one will watch movies in this environment. Light is the biggest enemy for projection, so lumens are also a very important parameter for projection. i300J is 400 lumens, the official website is introduced this 400 lumens is equivalent to the traditional light source projector brightness of 2000, this is because BenQ is using the ISO21118 international standard, while the traditional projector is using another standard, in fact, the brightness is the same It is recommended that you do not only look at the number of projections when buying a projection, but also look at the standard it implements. In actual experience, this display effect is still acceptable in the projector, but it is somewhat lower than the brightness of the same type of projector.
It is still possible to see curtains in the bedroom during the day, but not in the living room, unless a thick or light curtain is installed. However, during the daytime, the projection is not suitable. Therefore, it is impossible to replace the TV with projection. If you like to watch TV series or variety shows, you are advised to buy TV. Using projection to view movies is basically a matter of experience. Kind of feeling, this refers only to the ordinary home environment.
Quality
-------------------------------------------------- -----------------------------------------
The bottom right corner is LeTV's LCD TV. On the left is the contrast between the original image and the projection display. There are some errors due to the environment, camera, and technology. However, from the comparison point of view, the color reproduction of the i300J is clearly visible. BenQ's accumulated experience with projected color displays is still trustworthy, and this kind of thing can't be achieved without a good technology.
Virtual focus
___________________________________________________________________________________________
BenQ's projection name is "Eagle Eye" micro-projection, meaning that it will always be as sharp and clear as the eagle's eyes. Not focusing or focusing is the biggest highlight of this projector. Now many projectors use resin materials to save costs. If the heat is too high, the lens will be deformed, resulting in blurred images, which is often referred to as virtual focus. The reason that i300J is not called out of focus is to use 6 pieces of optical glass lenses, which have a lower thermal expansion rate so as to achieve a non-defocus. It is not enough to make changes only at the source. BenQ's patented TTCP extreme heat dissipation technology can ensure that the temperature in the core area is controlled within a suitable range. This basically eliminates the root cause of virtual focus.
On the left is to adjust the best focal length display after power on, and on the right is to use the display after two hours. As can be seen from the figure, the text is still very clear after a long time of use, and there is no occurrence of virtual focus. This BenQ is still very good.
Sound quality design
___________________________________________________________________________________________
The design of the loud speaker with two loud speakers ensures a strong sense of sound. After the loud sound at the rear, the whole effect is still very good. The sound is clearly structured, and the large shock under the big scene can still be felt, but the sound The surround effect is not obvious. If you put the machine behind the viewing position, the effect will be greatly reduced. Therefore, if the surround effect is not strong, the rear design of the speaker is destined to place the projector in front of the viewing position, 13°. Alice's design is destined to place the projector in a low position on the viewer. This places a great limitation on the placement of the projection. Generally, it can only be used on a coffee table or a desk.
Traditional intelligence
___________________________________________________________________________________________
The most intuitive change in traditional projection and smart micro projection is that the body of the smart miniature projector is much smaller and more portable. Of course, this camera is a little old. Nowadays, some of the traditional projectors have smaller dimensions. With the development of smart devices, smart projections have gradually increased, and the price has reached a relatively low position. However, at this time we also have new questions when we choose to buy. In the end, it is whether we buy traditional or buy the latest intelligence. What's good? Here we take a simple look at the differences between smart and traditional projections, so I believe everyone will have a few.
â– DLP and LCD
Both of these technologies have their own advantages and disadvantages. Both the BenQ i300J and my Lenovo use DLP technology. When I bought projectors, I started to see a lot of DLP projections in the basic market.
(Image from the network)
The principle of 3LCD panel projector is that the optical system uses strong light to form RGB three beams through the beam splitter and transmits RGB three-color liquid crystal plates respectively; the signal source is converted by AD and the modulation is added to the liquid crystal panel, which controls the opening and closing of the liquid crystal cell. In order to control the on and off of the light path, the RGB light finally converges in the prism and is projected on the screen by the projection lens to form a color image. This is the online Jie Shao. It should be noted here that this is how 3LCDs have 3 LCD panels. Previously, they were single boards. Although the price of single boards is lower than that of later DLP technologies, Therefore, the projection of the single board in the market should be gone. Nowadays, most of the mainstream 3LCD projection technologies are used in the more expensive projectors. Compared with DLP, 3LCD has higher contrast and better color reproduction, but the price is more expensive.
(Image from the network)
DLP is the projection of a DMD chip after the light beam is decomposed into R, G, and B primary colors by a high-speed rotating color wheel. The DMD chip is composed of many tiny lenses, each of which can rotate freely between +10° and -10° and is electromagnetically positioned. After the signal is input, it acts on the DMD chip after being processed to control the opening and the deflection of the lens. The incident light is reflected by the projection lens after being reflected by the DMD lens and projected on the large screen. Now the DLP has added more colors. My Lenovo was four-color. Projectors using DLP have a higher contrast ratio than LCD projectors, and black and white colors are more pure and richer in gradation. The light path system is designed to be more compact and thus has an advantage in terms of volume and weight. In fact, it is still more cost-effective.
The traditional projection heat dissipation is generally also a relatively large fan, the cooling holes will be larger, the noise will be greater, there will be light leakage at night, if there is nothing to hang the machine on the top, but if it is installed on the table There are still some implications when watching a movie. For projection, dust is also one of the biggest enemies. Traditional projections are generally because of many holes. The reason for large gaps is not very good on dust prevention. Generally, after a certain period of time, it needs to be cleaned, and now smart micro projection is Basically do a good job in dust-proof ability, do not worry about the problem of dust, this is also the advantage of intelligent micro projection.
Traditional projection light sources are generally bulbs such as the HUP, such as this association. The BenQ i300J smart projectors use LED light panels. There are a lot of LED light sources that are also used in traditional projectors. However, LED light sources have poor color, cold, and low saturation, but they have the advantages of energy saving, long service life, and low price. Did you see the blue paper on Lenovo? This is the time for changing the light bulbs. One light bulb took me more than a thousand. This is the reason why the traditional projectors generally have a high selling price. Although the HUP light is better than the LED in performance, it is not comparable to the LED in terms of price and service life. of.
Smart projection has more expansion capabilities. In fact, compared with the traditional projection, smart projection is not directly connected to the use of peripherals, and traditional projection must be connected to audio, computers and other equipment to be able to use, this is the biggest advantage of intelligent projection . To sum up, it is smart miniature projection portability, ease of use, price, stability, length of use, after-sales costs and other aspects are better than the traditional projection, but the projection of the main display effect is better than the traditional smart micro. Finally, we decided to look at our own needs. Now many traditional projections have installed intelligent systems, that is, smart projection (not smart micro), but the price is not low.
Advantages Disadvantages
___________________________________________________________________________________________
advantage:
1. The price is cheaper than traditional projection.
2. Excellent picture quality, very good for smart miniature projection.
3. The use of long-term use will not produce a virtual coke situation, and the experience will be better.
insufficient:
1. Work from packaging to the host needs to be improved, unlike the products of well-known manufacturers.
2. lack of APP support, sometimes mobile remote control is much easier to use than own remote control.
3. Video content is slow to update. Many old movies still need members to watch.
to sum up
___________________________________________________________________________________________
The BenQ i300J this intelligent projector does a very good job in terms of quality and non-defocus, which is also the core capability of the projector. BenQ's projection technology is also trustworthy. However, as BenQ's first intelligent micro-projector in the design and use it is to lag behind the same type of manufacturers, first in the use of projection appearance, manual focus adjustment, foot pad adjustment design are generally on the traditional projector design, as A smart projection can be more intelligent in these settings. Although the usability of the system is much better than that of the traditional model, it is harder to use than other similar models, especially the volume adjustment design, but it should be improved in the future system upgrade. The intelligent pico projector has a good picture quality. It is an aspect that is easy to use and can adapt to various usage environments. BenQ is not very good in this regard. It is hoped that BenQ will pay more attention to the use and operation experience of users in the field of smart micro-projection and make projection more intelligent.
