Inheritance and Subversion - Little Meter Projection Test

Additional amendments (2015-10-23 21:55:24):
To add, at the time of the test outside, it was already low-powered and automatically entered the power-saving mode. With light interference, the actual projection size effect should be higher than expected. Also for the external HDMI input, I have another game box test report with mango xiaoxiao debut demonstration

When I was young, when I saw the lecture hall, when the teacher used a projector to play the slide show, he always wondered if he could have a play at home, put a slide show, or even call a family member to watch the big movie that was put on the projector without going out. That's good. When I grow up, I have more things to consider. Traditional projectors give me the impression of shadow paste, low brightness, high fever, troublesome connection, short lamp life, and no portability. At the same time, business meetings Both the projection positioning price and the consumer level are too wide. I also thought about why it's better to replace portable TVs with portable high-definition projectors with playback capabilities, projection entertainment at any time and place. According to their own ideas, they searched last year and found that a certain universal treasure has already had a small projection based on the Android system, but the brightness, longevity, and resolution are not satisfactory. Therefore, they did not enter the pit and kept waiting. More in line with the expected product. The mango twilight that arrived until the first two days. It renewed its interest in portable home projectors.

Extremely beautiful, I believe that everyone should be a relatively new brand, I also heard last year, in fact it is also just set up in recent years, 14 years of successful financing and Z3 series of smart projectors allow users to gradually Learn and recognize. Do not know whether this product has all the disadvantages of the article at the beginning of the article, the pole rice proposed "non-screen super TV" concept, whether it performs well in practical applications, then take a look.

Video evaluation section:

For users who are too long to take long, you can directly look at the above video briefing and the conclusion below. =

Out of the box

Out of the box, not to mention the bright, but very simple design, through the front of the infinite color diagonal line of a meter without screen super TV slogan, easily put their own projection and other products on the market positioning Differentiate. The “Mango TV inside” corner sign in the upper right corner combined with the name of mango clams shows that this product has in-depth cooperation with mango tv. Put on the phone to make it easier for you to compare the size of the box.

The partner printed on the back cover is Baidu music in addition to Mango TV. Watching videos and music from the band are provided by Mango and Baidu, respectively.

Pull open the outer box, inside the plastic cover of the protagonist if many domestic mobile phone factory prompts film, suggesting that the switch / focus / mobile power switch / light position.

Move the protagonist, the bottom two small boxes are the power cord and remote control.

Power adapter, exquisite design, plug part replaceable plug design. See the name inside it, HuntKey's power adapter, there is nothing wrong, that is, the domestic computer power is very good first-line brand foundry, I believe the quality is reliable enough. The parameters of 19.5v 2.3A seem to be similar to those of the laptops in the home.

Under the leadership of the apple tv, the remote control of many domestic boxes is also similar, this is similar. Using Bluetooth connection, there are 3 buttons on the remote control that are different from the traditional box. They are screenshot, 3D, and image mode. There is a screenshot button that can be intercepted even under other HDMI input sources. The icon of the 3D mode is not clearly ideographic. Button feedback is not bad. Later I have loaded the attached 2032 button button.

The head of the remote control has similar infrared emission receiving devices, but it should not be misled. In fact, this is not an infrared remote control.

Look at the protagonist, the machine is 214X114X25mm long and wide, the front of the machine is the projection light source cover, and the side and front sides are access to the cooling holes. It may be due to the consideration of portability and price, instead of using the previous metal shell panels instead of the matte plastic body, plastics are very helpful in reducing the weight.

In addition, the appearance of matte soft rubber, dirt and abrasion resistance should be good, but if there is a choice, individuals are more inclined to bright metal surface. For heat dissipation will also be concerned.

Front logo and material details on the edges.

Bottom label information.

Put the MX5 together with the reference size.

Weight 605 grams, what concept?

This is equivalent to the weight of four MX5 points.

LED light source, high transmittance coating lens is a slide switch, slide open and projection will automatically open, put back on the cover, the small curtain will close the projector, this design is very good. The official data is that the sliding life can reach 200,000 times, enough to eliminate the concerns of users that this design switch is broken. The edge of the lens is a heat vent.

First of all, under the display technology, many cheap projectors on Taobao are single-chip LCD technology that is eliminated. The principle is similar to the slide projector used in teaching. The advantage is that the cost is low, but the light transmission is poor, and the conversion rate of light energy is also Not high, the projection of the picture is also uneven, we should not buy. The current mainstream display technology should be 3LCD and DLP. This DLP technology refers to reflective projection technology. Is the application of reflective DMD devices, while the mango is to use this small DMD device, LED light source, the size of the DMD is also theoretically the bigger the better, the mango is 0.3", the main Z4X meter is 0.45". The advantages of DLP are good contrast and uniformity, sharpness, and sharp colors. The projector's official nominal 250 ANSI lumens, used to seeing thousands of lumen parameters in the LCD, can't help but worry about whether this 250 ANSI lumen is enough. In fact, the conversion here is not the same, for example, the maximum brightness of the Z3 in the traditional sense is 1500 lumens, the international statement is equivalent to the official nominal 450 lumens lumens, because there is no specific national and international standards for lumens, for LED light sources, each Marketing and definition are all different. In this case, it is better to leave the parameters and wait for the perception of the experience behind the article to speak.


In addition, Otaru uses the same active shutter 3D imaging technology as the DLP Cinema movie projector. But the standard does not come with 3D glasses, perhaps the cost of shutter-type 3D glasses is relatively high. However, most users may not experience the 3D projection in publicity. However, I first entered a basic shutter-type 3D glasses experience in a certain treasure. Behind will bring experience.

DLP active shutter 3D glasses, first to buy a test 3D function first ~



The right side of the product is a manual focus knob. When the dial is stepped, it is very fine. The fine adjustment is convenient. It takes a few seconds before revisiting the local screening. The adjustment is clear. However, after focusing, this is not like a cell phone camera, so you can focus on it easily. Whether it can lead to follow-up auto-focus in the future, is it possible to achieve this goal.

The rest is the power jack/USB2.0/USB3.0/HDMI input/headphone jack/mobile power button. Portable micro-projectors can have dual USB ports that are very conscientious, and USB 3.0 ports guarantee the speed of reading large files. If you are unhappy with the poor performance of the game, you can access the contents of the HDMI projection professional console or game box. The finest hole on the far right is the built-in speaker. The sound is not as good as the Z4X, but after the actual test, it is fully enough for a regular viewing experience, and you can also output audio through a 3.5mm headphone output or a Bluetooth headset/speaker. Xiao Xiao also supports Bluetooth device expansion.

The left side of the speaker is a power button, 1W mA is sufficient to go out and fill your phone and tablet. When you press the power switch, the indicator in the upper right corner will be displayed. In addition, under the Tucao, before the front of all series of jacks are centered up and down, why the headset jack is not centered, is the old Luo's nut phone headset hole after the middle of the argument, obsessive-compulsive disorder that some uncomfortable, but combined positioning and relatively low pricing It also relieved.

A short press can check the power level. When the power is full, it is green. When the power level is low, it is red.

Directly to the first test to see, long press the power button for a few seconds to enable the USB port output charging, can be considered a large mobile power.

More than 30% of the remaining MX2 plug-in test, the output current of about 0.6A

There is also a Mango TV member redemption card with a value of 720 pieces.

The entire contents of the box are very simple, on these, host, power adapter, remote control and a manual, as well as the above member redemption card

Effect Play Test

In the parameter table of the projector, we can also see that the resolution generally has two indexes: standard resolution and compatible resolution. Standard resolution refers to the actual resolution of this product is 1280X720, which is the best resolution supported by the machine. The maximum compatible resolution is the maximum resolution that the machine can be compatible with. When playing a picture or video of this resolution, the picture is usually compressed, which affects the picture quality. Even if 1080P and 2k are played, the actual output is 720P. . So the basic test and playback are 720P.

The box parameter says that the projection ratio is 1.2:1 (76 inches @ 2m), then I understand that when the projection size is 76 inches, then it can be calculated corresponding to about 2 meters more points is the best distance (761.22.54 (inches converted to Cm) = 5792.2px), everyone can also refer to the next.

The projection was turned on for the first time in the evening, and it took less than 1 minute to open the projection into the system by sliding the lid. The first time it will be prompted to pair the remote control device to the device first (where the indicator light on the back of the remote control does this, non-IR remote control ~). Above is a white wall that I projected on the side of my home.

After pairing, you can press the remote control OK button, all the way to the next step.

The levitation wizard when entering the desktop. The desktop down is equivalent to the APP quick switch list, but it can only go back to the home page, and then down. For example, if the remote control in the global direction is down, it will be able to enter the APP switch. This is even better.

The box uses a custom UI system based on android4.4. The interface is still quite refreshing, thanks to 120% NTSC color gamut, the picture is more vivid and transparent than traditional projection. There are few APPs that come with it, and there aren’t any aggregate video softwares that are commonly used in the box to search for the potential copyright issues. In addition, GMUI lacks the background APP switching function, and it re-enters the flow slightly each time, which may limit the 1G shipment.

Attach the current version information.

Hunan Satellite TV’s recent copyright maintenance has made it difficult for VST and Tatelite, which are used by many TV box users, to find headlines for mango stations. The cooperation between Mango's mango sorghum and mango just solves the user's resource search problem. Although the official claims that there are hundreds of thousands of movie and television resources, the user uses the mango, mainly to look at the dad line, and every day, fast, these variety shows. Together with the bonus 750 member redemption card, the paid part can also be read with confidence. However, when watching TV movie buffers, ordinary users still have to look at advertisements for 30 seconds. They feel that since they have built-in cooperation with Mango TVs, they don’t want to put advertisements on watching free resources, like Meizu’s own. The video features, and Youku and other collaborative video sources, people did not play ads first.

In cooperation with Baidu Music, the official claim to tens of millions of music libraries, although in fact some of the copyrights are monopolized by other platforms, but the general songs are enough to use. For those who feel that they want to turn on the projector, it's a bit wasteful to put the music in to see the lyrics. Xiaoyan can only turn off the light machine, so turning off the light source is a good music player.

The game function is good, because there is no handle is not cool, no in-depth experience, configuration is sufficient to run some regular games. However, the actual installation space of 8G hardware is more than 3G. Install a few big games, download a few local videos, pay attention to the remaining space.

Built-in WPS, external multiple USB jacks, and keyboard and mouse support. It also conveyed the idea of ​​users who hope to draw a part of the mobile office. Maybe in the future is also a good breakthrough point. After going out at any place, you can insert a USB flash drive, connect the mouse, keyboard, etc., and use a small projector to project WPS. Maybe in the future, this can become a trend, and the office computer with a "non-screen transparent display" can be manufactured in a projection format.

In addition, the APP comes with a very good, is the electronic manual, because the package inside a basic description card, the machine built-in an electronic manual is very necessary.

Concerned about 1G memory, things open more, will be card? One-click cleaning is very convenient

As mentioned earlier, there are too few contents in the APP store. Now the solution has come, two kinds. The first one is the traditional U disk.

Insert the U disk with the data content into any USB port at the back, slide the left side of the projection to see one more disk, the first one is my U disk. You can install files, play local videos, and have built-in storage transfer files.

The other is the way I respect it. I feel more convenient. Just download the meter assistant.

The mobile phone APP can also replace the remote control. The mobile phone and the projector are on the same network segment. Open the APP and connect it automatically. Click on the right side to switch the remote control mode and more. Here we are talking about how to install the APP. To the projection, click on the assistant's APP to open the top left corner of the home page button, expand the left side button, click on "mobile resources" and then switch to the third tab above the last tab label "file", see the bottom of it, There is a "apk" category, you can see that you download some of the apk installation packages on your mobile phone, and you can automatically send and install them by clicking. Do not need remote control to confirm with extra points. It is much more convenient to install and open third-party APP than those of Tmall and Xiaomi's box. The TV meter of the TV meter avoids many policy risks on TV boxes.

In addition, there is also a nice two-way function for the meter assistant, which uses the “same screen” to synchronize the projected content to the mobile phone interface. The video is played in the mobile phone resources in the assistant, and it can also be transmitted to the projector simultaneously.

In addition, I would like to say one point about the projection to the ceiling. Although the trapezoidal correction function in the built-in projection setting is a good guarantee for the adjustment of the angle difference between the placement surface or the projection surface. After turning on the automatic keystone correction, the screen guarantees the rectangle. However, in actual applications, if it is erected on the ceiling, it may need to be manually adjusted several times. Because when you project up to the ceiling and you need to adjust the trapezoidal angle, do not open the "Auto Keystone" image above, as it will become the following when you open it.

The image above is the result of my automatic projection keystone projection on the ceiling. At this time, even if you turn off the automatic keystone correction, it will still not be restored. You must turn the remote control downwards, click the keystone correction, manually switch the progress, and then switch back to 0 to restore the normal display effect. This is still the case with the latest firmware.

Lose the following few nights, the white wall projection effect at home more than 2 meters away.

Before the projection test the next grayscale effect, in fact, in addition to the top left corner two or three squares can not see, other squares are very clear

The above two are 720P video, brightness I selected the highlight mode in the system settings, the actual display effect is more satisfactory, the brightness is fully enough.

The above two videos are HD test videos that often appear in TV stores. The original size of 1080P is the projection effect of 720P output. In addition, the 2k test video of the beauty and roast duck did not mean anything.

The above two use their own Mango TV HD mode, the difference between lights off at night and turn on the lights, in fact, turn on the lights at night and pull the curtains during the day, the screen did not imagine can not see, although the experience is not the best, but still It can be seen that I have watched half-day TV dramas during the day. The drawn curtains are very thin and transparent.

The maximum amount of money that can be cast on the Internet is 300 inches. I think that in order to watch the experience, usually after turning off the lights at night and night, the viewing experience should be better than 100 inches. But who does not want to try the projection of the large screen, then pulled the sister paper to help find the empty space downstairs to test the effect.

In the downstairs venue, when it was turned on, there was no electricity, and the original video test effect was immediately turned on.

Sister retreats to zoom in and adjust focus

Zoomed in to the height of the front wall, there is still a strong parking light on the side to influence. We can see the effect, although the definition certainly can not be compared with 100 inches, but the impact of such a large screen size, my sister and I all feel that the results are very satisfied, after all, is a home portable positioning micro-projection, when a cool screening The field is enough to deal with.

About the 3D function : Xiaoyan uses a shutter-type 3D with DLP technology. Although shutter-type 3D glasses are much more expensive than polarized 3D glasses (multiple used in theaters is polarization), 3D effects are stronger and brightness is higher.

Using the principle of online display, its lenses are two liquid crystal panels that can be controlled on/off individually. The liquid crystal layer has two states, black and white, which are usually displayed as transparent white, and turn black when energized. Through the signal emitting device in front of the glasses, the 3D eye and the screen can be accurately synchronized so that the left and right eyes can see the respective left and right screens respectively, thereby realizing a 3D stereoscopic effect. This process alternates at least 120 times per second to achieve a coherent, non-blinking 3D picture.

Of course, it may also be a cost consideration. There is no standard glasses, but I myself have bought one as a trial test at Taobao. The 3D film source is not much, but the free expansion of the meters, you can easily get to watch from a third party.

My video was found in a 3D movie with Mango TV.

Press the remote control 3D button, the screen will appear a variety of 3D classification, because the source file is left and right 2 screens, you can choose left and right 3D

If you don't understand what kind of 3D video this is, choose this automatic 3D and it will automatically judge

One more thing

Mimi also considers the user who has not worn 3D glasses or 3D glasses for a long time. However, if you want to continue watching this movie, you can use this last option and switch to 2D.

Take out my specially prepared 3D glasses, with 4 sync frequencies, maximum support to 144Hz. Already charged, press the button in the middle of the glasses to turn on the power.

After taking it with you, it really has the same effect as a movie theater. It is much better than the previous 3D experience of playing Google Cardboard and Stormglass, and the screen is not flickering. The glasses can be viewed for about 40 hours on an official electric data basis. It would be more convenient if it could be charged like a polarizer without recharging.

In addition, on the fever, the volume is reduced many, the main configuration is consistent with the Z4air, logically it will lead to increased fever, the measured high-light mode, after playing a few hours of online video, the hand directly attached to the box, the temperature feels at 30 The degree is completely acceptable.

Designed with separate air inlets and cooling vents, built-in adaptive temperature control system can automatically adjust the wind speed according to the temperature of the machine, here used the APP to test the noise of different screening modes, are the mobile phone clings to the loudest area .

With respect to life, the theoretical use time is 30,000 hours, and the maximum life span of the traditional projection standard mode is 3000 hours, which is more than 10 times. According to someone on the Internet, using 8 hours per day is enough for 10 years, so the lens is no longer It is the bottleneck of the current projector.

Life, under the use of built-in mobile power, playing video movies, extreme rice mango small crumb's life is about two hours or so, is regarded as in line with the official nominal 2.5 hours data. So outside the external power supply, you can play a complete movie with confidence. However, most of the time, I am basically using plug-ins. I believe that everyone will buy them. The main time is certainly plug and play. Therefore, you can rest assured. Regarding the battery, there are 2 claims on the Internet, Samsung and LG2 versions of the built-in mobile power batteries, I temporarily did not check this.

Does it meet the expectations of non-screen TVs?

The marketing plan for the very meters is very good. It gives the projector a name without a screen super TV, just as someone took the airborne stockings from the sprayed liquid foundation on the painted legs and immediately lifted the product to a new one. height. Therefore, the concept of product positioning is also very important. However, after all, compared with television, projection is still more willing to link projection and film. Super movie theater in the pocket of the official website's promotional page may be more suitable for this mango. In addition, Miji also gave a colorful shell version to this small series. Due to a series of orientations in the initial stage of regular product development that will conduct research and create products for users, we will combine the cooperation with the mango table and the lowest selling price in the currently sold Mimi. I suspect that Persona's Persona is a young man who enjoys working and playing, and his first smart projection.

Benefits summary

1. Lightweight & portable, completely unlike traditional projectors.

2. The use of LED light source, longer life, theoretical time is 10 times that of traditional projection

3. Dual USB port design on portable projection devices

4. The built-in 1W mA battery can act as a large mobile power source, and it can also be used to power the mobile phone.

5.android system, love tossing people's gospel

6. comes with the official mobile phone app remote control, easy to operate

Remaining shortcomings or suggestions

Also due to the portable positioning, the projector does not have traditional adjustment feet and hanging holes at the bottom, which may be inconvenient.

1. Basically no manual operation on the machine, thanks to the remote control, even if you can control through the mobile phone APP, but you can put some basic keys may be better

2. The problem of auto keystone correction during ceiling projection has not been fixed

3. The idea of ​​a non-screen TV is good, but the effect of projection is slightly different between morning and evening. At least, the daytime still cannot replace the living room TV.

4. The concept of a screenless TV has a potential limited policy risk after the slogan.

5. As an android device, the hardware is low, 1G storage is basically enough, open app slightly Caton. Want to watch the entertainment outside the video Recommend an external dedicated game box or xbox to output the screen

With its own power supply, compact body, built-in android system, etc., when inheriting traditional projection, Mango Xiaoyi subverted many people's views on the projector, but the extreme ambition of the meter is far beyond the expansion of the traditional projection industry, the proposed non-screen The concept of Super TV is obviously to replace the living room TV and occupy the user's living room. Although it is impossible to shake enough users in the short term, the positioning of the second screen as a TV is not a bad idea. As mentioned above, the price of 1999 is not too expensive, and the price is exactly the price of more than 40 inches of TV. Fortunately, the life of the current LED light source is assured enough. From the hardware and appearance, Z4 Air and the main hardware are the same, but Xiao Yan through the non-important part of the cost control, the original 2499 configuration can be pulled down to 1999, can be considered youth version of Z4 Air. The cooperation between Mimi and Mango Video Resources and Baidu Cooperative Music Resources, as a cooperative access platform, is a very good idea. It is a very good idea to complement each other and achieve win-win cooperation, which coincides with the concept of Meizu Connect to Meizu. It is hoped that in the concept of non-screen TVs, the meter will become smarter and better. Moreover, the concept of non-screen TV will still have some policy risks in the future, and TV-related boxes will be supervised by radio and television. The death of the dead, how to reasonably avoid future potential policy risks are extremely important to consider.

Many people are waiting for this sentence: For the first entry-level projection user who is watching and buying home, my personal recommendation is to recommend buying! Young people who are especially suitable for working outside work at night and are ready to watch TV on a white wall at any time, much better than landlords and small TVs.
