The quality is still huge screen? This is a problem - the use of BenQ I700 Smart Projector


Written in front: First of all thank smzdm and BenQ for giving me the chance to test this time. Secondly, taking into account the content may be above normal, so I put each part of the overall conclusions and mentioned first, followed by directory, easy to Friends of the value of selective reading. Article represents only personal point of view

Summarized in one sentence : entry-level home theater projectors, more suitable to want to see the big screen, while the image quality requirements are not high value of friends, cost-effective, from the viewing experience, personally think that better than the same price TV.

Specifically:

1, For the selection of projectors and televisions, it seems to me to be the choice of large screen and picture quality at the same price point. Taking the i700 as an example, the projection screen can reach 180 inches, while the television, 7k-8k , has a "poor" 55-60 inches . However, judging from the picture quality, the television at this price point is obviously better than the projector. But personally I feel, after the pass line picture quality to enhance the picture quality is far better than the screen size to enhance the shock (imagine your house guests, projectors 180-inch and 60-inch TV, obviously forced the former The number is much higher than ~6k. Between television and projectors, individuals tend to prefer projectors. Of course, before choosing, it is advisable to make a decision after comparing the feelings with friends.

2. Let's talk about the positioning and picture quality of the i700. I700 from the hardware point of view, and W1070 + basically no difference, is more than a Ali "YunOS 3.0" operating system. And W1070+, his promotional positioning is: For those who do not have enough budget, but want to have a full-HD home theater screen design , I think this also applies to the i700. As a projector for a home theater, I think that the i700 projector is just a start. Most projectors below this level cannot guarantee even the most basic 1080p . I think it's better to choose a TV. (After there is a comparison with 1024768 Hitachi projector, 1080p Konka TV)

In terms of picture quality , I think the i700 is a pass , but it is only a pass, and the TV gap with the same price is still quite obvious. Of course, this is a common problem for this level of projectors, after all, a penny. So you have plenty of hands , and if you have high requirements on image quality, go straight to high-end goods, such as the BenQ's W7500 . As for the 4K projector , the current 4k source is more and more, if the price is acceptable , 4k is also a good choice , do not have to consider the issue of upgrading for several years.

PS: The W1070+ is also a good choice if you are not paying attention to wifi . Continuing the outstanding features of the W1070, the core parameters and i700 are basically the same , wifi, smart features can also be made up through the mobile phone mhl, although not as convenient integrated integrated i700 but the price is also cheaper 200. Further, if the fixing position of the projector lifting well, and there is no requirement for mobility, w1070 also good. W1070+ Compared to w1070, the major improvement is the increase in brightness of 200 lumens , adding side-projection capabilities.

3, wifi and Ali "YunOS 3.0" operating system These two functions complement each other, so put it in one piece. On the whole, WiFi and Ali "YunOS 3.0" gave me the overall feeling that watching TV shows is good . If the picture quality is not high, watching a movie is also acceptable.

Then say wifi first, speed is flawed . The test result through 50Mb 2.4G 1.5MB / S, sometimes reach 3MB / S, may be interference with the surrounding channel 2. 4G relevant. 5G nominal 120Mb, the actual router close to i700, 5G transmission at several different time periods are around 2.5MB/S (Notebook 5G speed 11MB/S up and down, it should not be a routing problem), but anyway, smooth viewing Blu-ray movies, speed To 4MB/S or more. Even so helpful YunOS local area network to share high-definition movies to watch the value of friends in this area needs to consider the installation of USB cards, such as this, if the distance + through the wall, this can consider this

Afterwards is YunOS. How can I say this? The YunOS experience is good and there are many resources, but for me personally, compared with the previously used millet box, Mango, it doesn't make a big difference. They all have one thing in common: the quality of viewing movies online is different from local Blu-ray. . In my opinion, the Android box products look pretty good TV, HD resources or htpc system to connect with the projection win8 system. The PC ( Pirate ) source ( version ) is more ( none ) Fung ( Choose ) Fu ( Festival ), the system is fully functional without short board, the experience is better than Android, especially the Internet and video playback, not a level, more specifically My home video design and Ali "YunOS 3.0" section . Another look at the hot selling of boxes in these two years will know that for the box type of products, the market demand is still very large, everyone chooses on their own. Individuals are looking forward to having a built-in desktop i3 (or ultra-low voltage i5) level cpu , win system, wifi 300M projector.

PS: The main usefulness of the built-in "YunOS 3.0" system for me is to omit steps with boxes. If there are no boxes at home or there are movements, watching TV programs, wifi and YunOS 3.0 are still very practical.

4, Lifetime light bulbs. Although the built-in smart system, watching TV, Internet access is very convenient, but the lamp life problems still need attention, nominal normal mode 3500 hours , smart power-saving 6000 hours. There is no comparison with TV's life span of tens of thousands of hours. However, referring to the price of light bulbs, it is not a problem. As a kind of consumables, the bulbs will be guaranteed within 1000 hours within 6 months . This is basically the same for all of them, and the guarantee will not be bad.

PS: telephone consultation with the official service points, not counting change a light bulb 650, Billing 700 (refer to TV with the price of power and lamp life, i700 (w1070 +) per hour about to spend more than 0.1 yuan -0.2 yuan). Taobao on the 238 from the third-party light bulb to 400 + known as the original have, but after the unauthorized change of light bulb warranty expired . In addition, the maintenance point of the master informed, w1070, w1070 +, i700 bulbs common , Taobao search w1070 bulb on the line.

5, noise attention! "Three-dimensional noise reduction design as low as 28 decibels is almost the same as eliminating auditory interference in noise." This sentence is merely a copy of the advertising copy ( please refer to the difference between the nominal life of the notebook and the actual battery life ). Personally feel better watching TV, the Internet noise is still more obvious (projector to person distance 3m, standard mode, room temperature 5 degrees). Then went to the mall to compare the other machines in the same grade, feeling no difference in noise. However, each person's perception of noise is different. At the same time, the working mode of the projector and the brightness of the noise will be different. It is recommended that you read the actual object and then judge.

6, the brightness of BenQ's own high-end goods w7500 but also 2,000 lumens to know that home environment 2200 lumens enough.

1: Function introduction and analysis of the i700

BenQ's position in the projector market does not need me to say more? Look at the cover picture to know. I700 as a big factory product, the brand is still trustworthy.

From the propaganda copy, we can see that the flagship is intelligence.

Configuration is the shrinking Tmall box TMB300A+w1070+

The configuration of the smart part, compared with the TMD box TMB300A, memory 2G shrunk to 1G down no problem, but WiFi from 5G/300Mb, 2.4G/150Mb shrunk to 5G/120Mb, 2.4G/50Mb, to see if there are LAN sharing Friends will have a certain influence. Cpu graphics performance enough. An Bunny runs a minute

The router is wndr3400.2.4G and 5G are both 300m, and the speed of copying files under the notebook 2.4G and 5G is stable at 11MB/S.

The i700, 5G is stable at 2.5MB/s, 2.4G may be a problem of interference, floating between 1.5MB/S and 3MB/S.

Less than 4MB/s speed, LAN shared video playback of 20G+ remux video is hopeless. However, 1080p videos do not matter. There will be a separate explanation about YunOS 3.0.

The projector section is similar to w1070+

Projection, highlighting some of the more important features

1, short focal + side projection : These two functions are more important in the urban home environment where space is relatively cramped . In particular , accommodation in Kitakamihiro is generally non-Tokyo users . The short focal length guarantees that a huge picture can be projected in a relatively congested environment. The lateral projection, ie, the horizontal trapezoidal correction function, solves the problem that the normal projector must be mounted facing the screen to facilitate the movement from the living room to the bedroom. Although the side projection will lose the picture effect , he solves the problem of whether the picture quality does not require high-quality TV programs. Conditional or recommended positive investment.

Compared with the following two figures, the principle of correction is clear at a glance

The number of pixels is fixed. Under this correction, the deterioration of part of the picture is unavoidable. The following figure shows the screen shot after the orthopaedic treatment. The font on the right side is obviously more blurred than the left side. This is the price of correction.

Zoom in and see more clearly

In this picture, the orthotic opening is maximized on the premise that the picture is not deformed. The bottom edge of the triangle plate and the tile seam, the wall surface is basically parallel, it can be seen that the transverse orthopaedics can reach up to about 38 degrees.

Orthotics can be up and down, left and right, similar to the upper and lower principle, so it is not repeated here


2, six-speed color wheel This is mainly to solve the rainbow eye problem. Generally more than 4 times faster rainbow eye is not a problem. The i700 uses the DLP digital light processing technology of the DC3 chip , and the low-speed DLP technology is prone to rainbow eye phenomenon. (In addition to the sentence: In addition to DLP, projectors also have 3LCD technology, 3LCD is mainly used by some Japanese manufacturers, such as Sony , Epson . Both technologies are used in high-end machines, and which specific technologies perform well, there is no actual comparison. I couldn't say high-end machines too. In addition, because the optical path is not sealed, the 3LCD technology needs to be cleaned regularly.) Back to DLP, the principle is this

i700 employed RGBRGB color wheel color saturation and relatively good accuracy, but the same lamp, the luminance is relatively low. Some of the commercial RGBCYW color wheels are almost transparent in the middle. The color is not as good as the RGB RGB color wheel but the brightness is higher.

RGBCYW color wheel

RGBRGB color wheel

3,170 million colors 1.07 billion colors are generally and 10bit panels, 1024 gray levels appear together, the most obvious advantage is that the color transition is better. 1.7 billion color does not represent good color gamut , in general, 8 bit panel is 256 gray scale, 10 bit represents 1024 gray scale, the more the gray level, the more fine the color, the color transition is more uniform, it refers to the color The level is independent of the color gamut or color

4, the brightness of BenQ's own high-end goods w7500 but also 2,000 lumens to know that home environment 2200 lumens enough .

5, 3D glasses party said that the wear of 3D glasses is not friendly, individuals have been looking forward to naked eye 3D. In addition, it is necessary to add that there is no need to worry about using the 3D glasses to see the problem of reduced brightness. BenQ's brightness of 2200 lumens is enough to use.

6, Smart Eco energy saving official explanation is: according to the different input source brightness, intelligent adjustment of the light bulb power (30% ~ 100%), when the screen white peak brightness value is high, the power of the light bulb, the screen brightness When the lamp is dark, the light bulb automatically adjusts to a very low output power. At this time, the visual brightness of the screen does not change significantly from the perspective of the user, but the average power consumption is about 45% of that of an ordinary projector. % Energy savings, so as to achieve the purpose of saving energy consumption without compromising image quality . The actual experience, the effect is good, but on a white background , open Smart Eco screen will have a flickering feeling . For Smart Eco, from a national perspective, it can achieve up to 70% energy saving Smart Eco contribute to energy conservation. For individuals, Smart Eco reduces the cost of light bulbs. This technique must have 32 points .

This is a comparison of the normal mode and Smart Eco. The camera aperture shutter setting is the same.

Most of the time, Smart Eco will not make much difference, but on a white background, the screen will have a flickering feeling.

A total of three modes, Smart Eco, energy saving, normal. Smart Eco is an enhanced version of energy saving

In addition, when the shutter speed is increased, such a screen shot is obtained, which looks almost the same as the display strobe. Open normal mode, no strobe feeling, Smart Eco, white background has a strobe

7, audio 10W theater-grade speaker This official publicity look just fine, watching TV is no problem, but if the audio is a bit demanding, on the headphones or audio, 10W power is placed there, and the sound effect is completely Not a hierarchy. As for headphones, personal feeling, the effect of directly inserting hd598 is better than the loud speaker

8, heat, noise and power dissipation feel better . Go to the mall contrast feel a bit of the same level projector on the noise feeling is not everyone's different. 28 dB is estimated to be ideal noise, similar to the notebook manufacturer's nominal life and actual life. The distance between the projector and the projector is 3m in the standard mode. The noise is obvious. 20 decibels is roughly equivalent to a soft-spoken whisper, rural nights; bedroom, desert night, is basically 30 decibels. The power consumption is bigger than the TV with the same price, but it has no effect. Let's take a look.

Additional explanation: I have an infrared temperature gun. This kind of temperature measurement involves a problem of reflectivity, because the reflectivity of the i700 shell is not clear, but the reflectivity of most organic materials is 0.95, so the temperature There are a few degrees of error is normal, and the temperature is affected by the ambient temperature, light bulb pattern, and even the picture of the floating range is relatively large, but the regular manufacturers produce things, do not worry about temperature control. The temperature gun test here just gives you a rough idea of ​​what the heat sink's temperature is roughly within.

Ambient temperature

Outlet plastic

The following temperature is obtained by aligning the muzzle with the gap of the heat dissipating hole in the machine's internal test. It is impossible to see what part of the material is inside the muzzle at the end. Because of the problem of reflectivity, the accuracy is doubtful.

In terms of noise, there is no measurement. Because after buying a decibel meter, I only talked about the noise without talking about the numbers. There is too much interference from the environment in the home environment, and the decibel meter test data cannot be seen. In addition, each person's tolerance for noise is different. The machine operates in different modes. At ambient temperature, noise is also different. Therefore, it is best to actually experience it. Other people's feelings have limited reference value.

Power consumption, standby less than 1w

Smart Eco, 200w

Standard mode shuts down energy

All within the nominal 350w

2, My home audio and video design and Ali "YunOS 3.0"

The core of all problems is SARFT. I set up a home LAN, and I used htpc, nas, and smart boxes to download and share the LAN to the LAN (slightly similar to smart routing). I personally chose htpc. First of all, nas, the structure of hardware and htpc is very similar, but there is a program developed by the manufacturers to support, really easy to use, and powerful. However, the problem with NAS is that I want to access the Internet on a TV and use a potplayer to interpolate the frame to soft-decode the movie . I need an extra htpc or even a laptop every time.....the smartphone downloads and shares it with the LAN. Like the NAS, the problem requires a computer to link the TV, and does not seem to support raid. So, I think it is most practical to use a htpc that does not shut down the raid1 or win storage pool for 24 hours .

Then why do I insist on using the potplayer soft unplugging frame to play video? This will be the SARFT. As we all know, our country wants to chase the American drama. If we don't want to delete the festival movie, we need unofficial channels and subtitles. Then the question arises. What if the subtitle video is not synchronized? See half of you want to go online to watch the film review analysis how to do? What if you want to review the fine ( wear ) color ( help ) screen frame by frame? With the problem of inserting a frame to play , smart TV or Android box, the convenience of this aspect and pc are totally impossible. There are download problems , although there are software such as mobile phone Thunder, but for my personal feeling, or win platform , download files the most convenient . And since it is determined to use the pc, then adding two hard disk groups htpc is not a matter of course, is it a matter of course, multi-disc nas price is also very expensive.

However, although watching movies is very convenient for watching American dramas, PCs are not as good as box products in watching domestic TV programs. Especially for elderly people whose eyesight is not very good, it is difficult to operate a computer on a sofa. So I also need a box to solve the TV program problem.

This is the current appearance of my living room. The router on the stereo solves the problem of poor signal after the wifi passes through the wall. There is a computer behind the TV. It does not shut down for 24 hours to play pt and Thunder, incidentally solving movie problems. Incidentally, if you install a graphics card, the TV game is very cool, but the whole power consumption is difficult to control below 30w, 24 hours boot power consumption is a bit big. My host configuration is i5 3470, 8g memory, 128g hard disk 2 no fan, power consumption 20w, and nas little difference. If you install gtx760, the power consumption of the whole machine is more than 50w.

Here say a few words, if you do not raid or storage pool backup function, then boxed with Android phones Thunder download, and share is a good choice, when television movies temporary plug my book, notebook television boxes shared reading The data is also very convenient. (i700 can not be used to hang Thunder and the like, as long as the boot bulb is on, projector lamp life is limited)

Closer to home, compared to other projectors, i700 is the most prominent self-intelligent function, without the need for additional boxes.

In general, Ali's "YunOS 3.0" experience is not bad, and all kinds of functions are also very complete, but everyone is Android, and it feels very little difference with the current use of mango.

There is no difference between the appearance of mango and other boxes, and i700 is built-in, so there is no need for him.

Set up the network, 2.4G, 5G take-all

The options are simpler than the mangoes in the picture below.

The main page, at a glance, is suitable for remote control operation

The design of mango pods is similar to him.

China TV Content Access

The difference between Mango and his design is not great

Mango å—¨ built Thunder

Ali "YunOS 3.0" backed Alibaba, Taobao naturally can not be less, built-in shopping function

See product reviews, profiles are no problem

Ali "YunOS 3.0" Search Video

The design of mango pods is slightly different

The mango keyboard has the same keyboard layout as a regular keyboard

Ali "YunOS 3.0" is arranged alphabetically

There are Ali tv assistants, Mango's WeChat mobile phone remote control. Etc.

In general, each of these functions can be done in the box, even if there is no built-in thing is the next app. The experience is also very convenient. In particular, the core video features are not different. There is nothing to say on the main function. Here are some details on the problem after I used Ali "YunOS 3.0" for a few days.

1, Ali "YunOS 3.0" default does not support third-party input method , but Baidu : Tmall Magic Box for third-party input method detailed tutorial (without root) can solve this problem . This will not be repeated here. Personally feel that for the remote control, the default input method is enough, no need to change.

2, Ali "YunOS 3.0" supports mouse operation, however, the remote control cannot be replaced, and it is not necessary to use the projector to control the projection part. To say "YunOS 3.0", some operations must be done by the remote controller, and the mouse cannot . For example here:

Want to uninstall the program, mouse click directly jump to the es file browser, click on the remote button will appear delete button

3, if you plan to use the touchpad , try to choose with the physical left and right buttons . I use the Logitech t650, because it cannot be selected by touch, and it is not easy to use it in the environment where the touchpad is placed on the leg. Unlike the htpc win8 system, a t650 solves all operational problems.

4, this is a common problem of box products, APP online playback quality is not as good as the local play of blue light . Looking at the enlarged maps of the following two figures, the normal viewing distance is not obvious, but after the contrast is played, the difference in picture quality can still be seen.

Say a few words: Take the exorcist as an example, telecommunication 20m network, Thunder download about 3.5M

Then the original disk to remove the multi-national audio track, tidbits, real video but 18.7G

Online play is still possible, do not know why the TV box does not have this level of quality to choose from ... now 20m broadband users are not too little now

5, es folder can easily read pc shared files, LAN play movies is very good, specifically, PC side, select the folder to share, right properties → share → select everyone, share center where the same changes,

Then es folder → LAN scan, on the ok, depending on whether the pc has a different password, you may be required to enter the pc username and password

6, the Internet has an otg line and the value of the Andrews mobile phone to try to know it, you can , but there is a gap with the computer experience

The picture is uc, if I want to switch labels, more than two steps on the pc to operate, but also not like the web browser bar as always shows the bar, Baidu have to spend some trouble.

Antenna small tail

The antenna is a sma interface. It is also possible to replace a high-gain antenna or a flat panel antenna. However, personal feelings are of little significance, there is a demand for network speed, and it is king on the USB card directly.

bottom

It can be seen that in addition to lifting screw holes, there are three fulcrums, of which two fulcrums are adjustable

The first fulcrum is not recommended for adjustment. It will cause the picture to be distorted and trapezoidal correction must be used. The trapezoidal correction will lose the image quality

Adjusted to narrow the width of the screen on the wall

The front page of the manual is very illustrative of the precautions for use

The remote control has a luminous design

Through the cooling network you can see the rear fan and speaker, the fan looks like the 6010 specification


4, i700 and TV, projector contrast

Explain that the i700 is a home projector, and my Hitachi HCP-430X projector is a business model. Compared with home models, business models generally have higher brightness and poorer color than households . Lamps ( make ) blister ( use ) life ( into ) life ( this ) is longer ( lower ) than daily use of the Internet . For comparison, individuals are advised to go to the mall for actual comparison , because the comparison chart cannot reflect the advantages of the i700 giant screen. Smear problem three machines are okay, mainly the difference between color, resolution

Hitachi HCP-430X
