First of all, I would like to thank ZDM for giving me this opportunity to review. Projection products have always been more professional equipment in people's past impressions. They are relatively complicated to use, have relatively high requirements for the environment, require many supporting equipment, and are not cheap. Therefore, it is generally the audio and video enthusiasts who use projection to watch movies and television. However, in recent years, a number of manufacturers, represented by Mami, have marketed micro-input products and sold them through e-commerce, making projection of such relatively niche products into many people's families. The reason why micro-investment can be fired up, indicating that its positioning is still very accurate, this point in my evaluation of the use of this obviously can understand it, and will specify later in the article. The price is relatively high in the micro-investment, for a full HD LED projection is not expensive. This review focuses on measuring its own habits in combination with its own conventions. It will inevitably lead to a failure to focus on everything. I hope to give you a reference. The content of this article only represents my personal opinion.
Before the evaluation is still a brief introduction: Polar meters H1S is an upgraded version of the former pole meter is also a hot one of the H1, its overall basic and predecessor is the same architecture, the appearance is basically the same, mainly for H1 to carry out some upgrades. The aircraft continued to use a 0.47-inch DMD chip specifically designed for micro-projection by Texas Instruments, with a resolution of 1920*1080, which achieved full-HD resolution, detached from previous toy impressions of 720P or even lower resolution. Nominal maximum brightness of 1100 lumens, the use of micro-casting the most commonly used LED light source, LED light source is characterized by high efficiency and long life, the pain point is difficult to achieve high brightness, but with a long time the color cast danger. Two 45mm diameter full-range speaker units are built-in. The weight of the machine body is about 2.1kg. Using a fixed-focus lens and autofocus system, the self-contained intelligent system can be plugged in directly and independently.
First, unpacking, accessories and appearance
The outermost one is a cardboard box, or a seal that has not been collected. It is estimated that it is directly sent by the manufacturer.
Basic product information, the original projection is from TCL OEM.
Open the yellow carton box first to see that it is an attached iron transfer tray. The weight is not light. Its function is to look at the cover. It will be connected to the bottom of the device through the four corners of the projection screw. There are standard screws on the plate, which can be used to fix on special meters or ordinary tripods. This is very important for micro-projections that are often moved.
Take away the air cushion to see the main body of the machine, a black carton
Open the box and remove the foam to see the inside of the machine.
Remove the machine. Here are some accessories and instructions.
The manual and warranty card, as well as the recommended accessories list, are nothing more than brackets and curtains. This is an on-demand purchase. Many things are generic, and you don't have to buy a meter yourself.
The power adapter you got so big is a few meaning? This should be the largest power adapter in my home. The micro-investment is not small at all and strongly requires improvement. The length of the power cord is estimated to be okay, and the cord will not feel too short.
Remote control shell is black plastic, it is said that the former is aluminum alloy, but feels good feel, triangular design to facilitate grip, the button is not many, with a few basic blindness, which is often used under conditions of shading The projection is very convenient, with a pair of batteries in the package.
Due to the fact that I have not used the product before, I discovered that there was a switch on the bottom of the remote control after a while. It was mainly used to start the autofocus. I didn't know that I had to restart it when I had to refocus.
There are so many accessories, let's take a look at the main equipment. The appearance of the machine is not different from that of H1. It is difficult to distinguish it without looking at the label estimate. Black and silver color, the lens is not large in the ordinary projection, in the micro-cast in the eyes
The lens cover is manual, both the role of switch machine, some people do not like the manual lens cover, I feel inconvenient to switch on their own each time, but I do not matter, first, in addition to lifting (to buy it for lifting people should be very few ) Manually opening and closing the lens cover is not a hassle. Second, the lens itself is not so easily affected by dust. Occasionally, it is not a problem. The switch lens lens is a fixed-focus lens, which means that the size of the projection screen can only be changed by adjusting the projection distance. This is also due to the size and cost considerations. Compared with the HMI, H1S has a key change that is to replace the glass lens. The resin lens improves the abrasion resistance, but even glass lenses do not recommend regular cleaning. A little bit of dust adhered to the lens has no effect on viewing. Instead, the effect was great.
The rear part of the machine is a physical operation button. Usually used in an emergency, it is generally controlled by a remote controller and is rarely used.
There are two full-size units with a diameter of 45mm on the front, developed in cooperation with Harman Karton, but only two less than two-inch speakers do not expect much good results, just a few hundred units of the Bluetooth speaker's unit configuration This is much more than this, I have measured the price of WIFI speakers less than 800 yuan, and Harman Kardon from a foundry, there are two 1.75-inch full-frequency unit plus a 3.75-inch bass unit . But the strangest thing is that the unit faces the direction of projection, which is difficult to understand, because no one can get the correct direction of sound either sitting in front of or behind the projection.
On the back of the machine, the red box is the outlet of the two cooling fans. When installing and using it, remember that you cannot let the wall of the outlet too close and cause poor heat dissipation. Below the air outlet is all the interfaces of the machine. It can be seen that this machine is completely home entertainment positioning, a headphone port, a LAN port, a power input port, a fiber optic port, two USB ports (one USB3.0) and Two HDMI interfaces (it is estimated that HDCP2.2 is not supported, no support is used).
At the bottom of the machine, you can see two passive diaphragms, mainly for the bass service. Most of the bottom is the air inlet of the cooling fan. It also means that the bottom air inlet cannot be pressed when in use.
The volume is not too large but it is not too small. In order to let everyone see it more intuitively, I put it in contrast with the two projections I used to stand on this site.
Oblique side:
As you can see, compared to the Sony VW328, the Mitsu H1S is still relatively compact, but the Sony VW328 is already a big man in home projectors, and even larger than it is a few home projectors, compared to portable Sony MP -CL1A will be mostly, but after all the positioning is not the same, the nominal brightness of the meter is 30 times faster than the Sony micro-projection, many people say that the two 45mm speaker unit led to the Mi-mi H1 series than other micro-projections A lot bigger, this is a bit biased, although the two 45mm units do occupy a certain amount of space, really take up the main space is the light path and cooling system, use the self-promotion map of the meters, the larger chip corresponds The increase of the Deguang Road and the two fans and the corresponding air ducts are the main reasons for the increase in volume. The 0.47-inch DMD is more than double the 0.3-inch DMD commonly used in other micro-projections, and the corresponding optical path is necessary. Increase a lot, but the increase in brightness is a direct result of the increase in heat, so it is a lot of heat, but in order to effectively reduce the heat in the rice while not significantly increase the wind noise using two fans at the same time. The so-called fish and bear's paw can not have both, high brightness and high resolution brings the increase in volume and weight, which is no way.
Second, the test machine and built-in system is introduced briefly
In order to facilitate the use of micro-cast or put on the bracket is better, there are a lot of different types of brackets in the official accessories. I have a tripod on my own and installed the adapter on the machine first. It is very simple to install the adapter. After removing the original four cushions, the spacers should be well secured. This is to ensure that there is a certain gap between the plate and the bottom of the machine to facilitate heat dissipation. , and then use screws to fix the adapter plate.
Then connected to the tripod, so that easy to adjust in multiple directions, can solve the screen problem by adjusting the projection as far as possible not to use trapezoidal correction, which will be explained later.
After the power is plugged in, you can turn on the lens cover directly to start the system. The first time you turn on the power, you need to match the remote control and connect your home WIFI. The first test machine was in the afternoon, and the conditions for shading were generally just a thin curtain. Everyone could look at the effect of the daytime. The curtain is a 135-inch picture frame with a gain of 1.25.
Each time you turn on the default will be an autofocus, this setting can also be turned off in the setting options, according to the use of a few days, the situation of the camera lens is still happening, it is recommended to default autofocus. It takes about 10 seconds each time after booting up to enter the main menu, which is mainly for advertising in meters. In general, the boot speed is also OK.
The machine comes with a focus map, you can tune it out as a reference when you need to focus, when you need to refocus, touch the focus of the bottom of the remote control can be, for micro-projection this often moving projection is automatic Focus is still very necessary.
In general, the display effect under certain lighting can also be, but the projected area can not be too large, 80 inches or less, too much to hold on, but with a 1.2:1 projection ratio of the aircraft, the basic vote It takes about 4 meters to fill my 135-inch curtain. It takes a lot of distance to get a big shot.
The built-in system is still relatively concise. Basically, it will look like it. There is nothing very special in itself.
This is the main interface (taken during the day). The most important movie is placed on the first. What music station and games behind are at least not used for me at least. The no screen assistant needs a mobile phone to download an APP. Through this APP, you can use the phone to control the projection, and you can transfer video and software to the projection through the APP. To put it plainly, an intermediary uses WIFI to transmit data.
The apps of Tencent TV and Youku TV have already been completed and can be seen on the main interface.
Go to the projection settings and see the contents of the settings options
Here to talk about the problem of trapezoidal correction, the essence of trapezoidal correction is to display the screen on the chip as needed to compress, remember that only compress a choice, the difference is only the degree of compression, the result must be the picture degradation, not really there is no way Do not use as much as possible, personally think that there is not much situation can not be properly projected by adjusting the projection position, even if the bedroom vote can be mounted on the wall before the wall mount, after all, this is a large volume is not too large micro-cast . Of course, there are not many problems with doing some minor corrections. The trapezoidal correction ability of the aircraft is still relatively strong, and the adjustable range is relatively large. The green arrow in the figure below is to adjust the direction and degree.
Anyway, to test it out, I cast the projection in the ceiling and tilt it to create a trapezoidal scene:
The trapezoidal picture is as follows:
Through adjustment, the corrected image can be seen, although we have obtained the rectangular image we want, but the picture is much smaller, which is the result of compression
The promotion of the aircraft is also a contrast enhancement, said plainly is the dynamic aperture in ordinary projection, the main purpose is to enhance the performance of the black level, the ability to improve the contrast ratio of the viewing time is limited, mainly to enhance the FOFO contrast is all black White, in fact, no meaning. We took two pictures to compare the difference, anyway, I think there is no difference.
This machine is one of the few projectors that use Deyi's 0.47-inch Full HD DMD chip, which ensures the fine detail and sharpness of the picture quality. The first time this task was completed was good, a close shot, we can Take a look at the size of the pixel grid.
Third, the connection method and ease of use Comments
The most direct and most commonly used playback method of the player is to play the video and audio resources owned by the built-in system. The direct point of the player is the same as that of the mobile phone and network box. The main content is still online content. After all, the micro-projection product is convenient. The performance in this area is not bad. The contents of the built-in content plus several other downloaded APPs are still quite impressive. So there is no big problem with the basic disk, which is enough for most people, and it is convenient to use. Various classifications and searches allow you to quickly find the corresponding resources.
However, these built-in resources also have their own problems. The first is that resources, especially mango TV, have the highest quality and only provide high-definition video. What is the level of high-definition video sites? Everyone knows that if you look at the phone, it's okay to project it on a big screen. The clarity can be imagined; secondly, the built-in APPs are all independently charged, and now many people have bought members on the video APP on the mobile phone tablet. As a result, the TV version APP has an additional charge, which is simply JS, so it has the following The playback method is to play the contents of the mobile phone, there are two ways for the extreme meter H1S. The contents of the mobile phone are played on the projection. The first is through the AirPlay technology through the WIFI screen, Polar meters H1S support AirPlay, Miracast And DLNA these three kinds of mainstream screen technology, but this is a test of the speed of the WIFI at home, at least in my family's small water pipe can not play.
Take your mobile phone and try it with AirPlay. The success of the same screen, but the delay is scary, the speed is not enough meaning.
No way, you can only choose the second mode is a wired connection, which is transmitted through the HDMI interface, so there is no limit, but it is a little trouble to bring a tail.
The following is the cell phone to play Tencent video in the movie and then input to the projection, the definition of choice "blue light", I feel a bit reddish color, before the video played with Sony micro-projection also have this situation do not know if this is a common way of playing .
Of course, any device that can be transmitted via the HDMI cable can be played on this device except for the HDMI cable for mobile phone playback. Computers, TV boxes, HD set top boxes, and Blu-ray players and players are all OK. There is also a direct U disk player can also play. On the left side of the main screen, you can choose to play the signal source.
It also comes with 10GB of capacity, you can put resources to play, you can also connect home NAS access playback, but because my family does not have such equipment, there is no test.
In general, the playback mode is more diverse and suitable for different groups of people at different locations and different modes of viewing. But the most convenient is the built-in system, micro-casting is to be convenient, with a bunch of equipment behind it is not convenient.
The machine's operation is relatively simple, plus a tripod for a variety of projection methods, including the ceiling, and the effect is not bad, of course, this is a test tripod, or the center of gravity is likely to fall to the machine.
The machine is not large, but its huge power adapter still brings some unfavorable influences on the convenience of use of the machine. The line is not well vacant, which indirectly leads to the inability to make full use of the length of the outlet, and sometimes there is a sense that the outlet cannot be used.
The projection ratio of the aircraft is relatively modest. In fact, it is not a good thing that the projection ratio is too large for micro-projection. The ultra-short-focus lens brings serious distortion and dispersion, and it is difficult to find a suitable surface in many usage scenarios. The large white wall has limited its use.
The noise level is one of the highlights of the aircraft. I used BenQ's GP10 before. It is also an LED light source and its brightness is only about 400 lumens. However, its noise is very scary. One meter of H1S is relatively large and then uses two. The fan and the large area of ​​the air inlet and outlet allow the fan to complete the cooling task with a relatively quiet operation. It is worthy of praise here. Of course, the consequence of this is that the machine has a relatively large volume, and noise control is relatively important. Otherwise, watching the movie at night in the dead of night can make you bored. Of course, the temperature during testing is about 18-20°C, and I don't know how to perform in the high temperature environment in midsummer.
Regarding the question of whether it is necessary to have a curtain, I think so. If you use it as a TV or home theater projection, as advertised by Mimi, then a screen is necessary. A smooth, unblemished and white piece must be found at home. It is very difficult to have walls of sufficient area, and a fair amount of money cannot be used for a white curtain. There are mainly three categories of curtains, picture frame screens, electric screens, and portable support screens. The first two are considered for home use. Buy a few hundred or so on it, no need to pursue too good, stents are mainly used for outings, this type of curtain is not light weight, no car is not good with. When you go out, you still have to invest in a white wall, except for the larger ones. For the brightness of the meter H1S performance to be able to look under a certain external light can also be seen, the screen should not be too large, cast an 80-100 inch on the almost, like the 180-inch recommended by the meter is purely nonsense, that is, All 1100 Lumens 180-inch dark cast will be bleak. If you only use micro-casting, watching movies and TV shows on the Internet at any time and anywhere, the curtains can be no more, convenience is the first.
A projection of the white Nadami meter does not buy a part of the pole meter accessories is also a little oversight, on the flagship store to see what accessories can be bought, just to fancy a special package, is equipped with a pole meter H1, and pole meter H1S and H1 Is a shell, so it is also for the H1S matching, buy a package for easy use.
After the package arrived, I tried it again. I feel pretty good and the size is moderate. The inside space can be installed even if the machine is equipped with a transfer tray.
The main body of the machine is equipped with a transfer tray, and the power cord and remote controller are installed together.
Let my dad be a model, it is a shoulder bag, with a special package to go out is more convenient.
Fourth, sound quality and quality testing
1, the sound quality part
First of all, talk about the sound quality, in fact, there is nothing to say, like the TV you bought with the speakers, will not be strange but do not have too high expectations, the overall performance is good, than the average TV The horn is still stronger, but bass performance is also important. However, there are still some problems with the vocal position mentioned above, and listening to it will be a little strange. However, no matter how you want to test it, the test method is to record with a Sony D100 voice recorder and record the MP3 with a 320K sampling rate.
In terms of test content, it is just that the machine has its own audition divine song "River" and music uses it. The movie sound effects consider choosing online content instead of Blu-ray discs after a third time. This will be closer to the mode of use of the local users. The movie is selected from the “Wrath of the Neptuneâ€. I have previously tested this in the singles in the panoramic sound theater. Video recording, but the source Blu-ray disc, you can compare it. Put it on the web disk and listen directly.
Ferry recording clip
In order to reflect the true sense of hearing in the movie playback test recording, the recording pen is placed in the normal viewing position and the microphone is facing the screen instead of the speaker.
"The Wrath of the Neptune" recording clip
Polar meters H1S also supports external audio through Bluetooth, which is to connect other Bluetooth speakers to play the audio of this machine, this test is no problem, but there is no way to use Bluetooth to connect to my Denon X7200WA amplifier, if successful then we must be more convenient The sound system that can be accessed directly, the effect will naturally be strong. However, the projection itself is used as a Bluetooth speaker, at least I did not try to use the sound of my mobile phone to do a successful test or change to AirPlay successfully, but with the volume of the aircraft there is a huge power cord, use it to Bluetooth speakers are really not practical.
2, picture quality (focus content)
The following focuses on the picture quality, say one thousand to ten thousand. The most important indicator for evaluating a display device is the picture quality performance. However, for a micro-projection product, its use scene and environment, etc. determine that there is no need to excessively demand the image quality. This is not a big meal but a home cooking. Brightness This section has already mentioned some of the above, using the photometric test to open in the viewing mode to the brightest of about 700 lumens, the performance is still good. The peak brightness is not measured, the viewing effect is better or the viewing mode is more appropriate, and blind adjustment will obviously lose the contrast.
The quality test still uses the old method of screen capture. In order to maximize the image quality, the player chooses to use a Blu-ray player and a Blu-ray disc. Of course, 99% of the users will not watch the movie this way. The projection screen is 135 inches, the basic is full, the throw is about 4 meters, and the trapezoidal correction is not used. Screen camera using Sony A7R2, RAW format records, later converted directly into jpeg, just transfer the format without any other processing. All screen shots cannot fully represent the on-site look and feel and are for reference only.
The disc player is a BDP9700 from Philips. The picture quality of a 1080P Blu-ray disc is very good. There was also a bill before.
The choice of the disc was abandoning. The color of the disco is not unique to the new cartoons released by Hollywood. However, the colors are too fake. I never use these films for reference. The picture quality of the movie is quite different, and some of the same VFX content is Many, so it is still a good quality documentary is best for testing, choose to choose to go, choose from the IMAX documentary series, enter the era of UHD, IMAX preemptively launched six 4K UHD documentary in one breath, because the use of IMAX camera shooting So all of them are quality reference levels, and each of them is in my pocket. Because the U.S. version of the disc will be accompanied by a BD outside the UHD, this BD will be used to test it. The movie chooses "The Monarch Butterfly's Migration." The UHD performance and 3D performance of the U.S. movie are burst-level. As for BD, it was because of this test that it was only for the first time.
Directly connect the projector and the player with the HDMI cable.
Insert the disc and start playing. Screen shots are as follows:
Take a picture at close range
Also come close to a
From this point of view, the performance is still good, there is no particularly outrageous color cast, 1080P DMD sharpness performance is also very good.
The machine claims to support 4K, just U disk 4K video, all MP4 format, inserted in the machine to play some, found the following problems, first HDR video not even think, 4K 60P non-HDR video can broadcast, but From time to time, the card will be played, and the 4K 25P video that you played with your micro-single will play smoothly. Then when you play Sony's 4K demo, you feel that the color is strange. You also took two shots. Let's take a look.
Finally, let's take a look at the performance of the photos. The photos are my own photos. There is a very strange problem with the photos played by the meters, that is, it will automatically stretch the screen, my photos are 3:2, in my Sony projector playback is the original proportional playback. As for the release of the original map, I thought for a moment, because the screen shot itself is inevitably color deviation, so put the original picture is a little bully projection, so still forget.
Taking the central part of the 100% zoomed-in screen capture, you can further experience its resolution performance.
Then, playing the same photo with my own 4K projection also took a picture, and everyone can compare the difference in their resolution performance.
Because there is no special 3D glasses for 3D performance, the 3D glasses are very expensive, and much more expensive than my Sony BT400A glasses. 3D is not used by people who do not watch Blu-ray discs. Not to.
By the way, even though I have two projections on my hands (we've sunk them before), I didn't compare them with any of them. The reason is very simple. The three projections have bigger parameters and positioning. Differences, it does not make much sense to put together a comparison, everything has its own position, the comparison beyond its position does not make sense.
V. Summary
Let me briefly talk about the advantages and disadvantages of this personal meter H1S that I personally think of:
advantage:
1, mature design, good appearance, the lens is replaced with glass material to improve the anti-wear performance;
2. Adopt DME 0.47 inch native 1080P DMD, which has the resolution and picture quality beyond the general micro-projection;
3, LED light source, has a good brightness performance, even if used during the day, after a simple shading can still be viewed;
4, the system is simple and easy to use, features more complete, auto focus is very convenient;
5, the noise level is controlled very well, with the speaker effect can also;
6, the remote control feels good, the number of keys is not much, a reasonable distribution, feel good, easy to blind.
Disadvantages:
1, the size of the machine is still a bit large, as a small change completely used before the shell can be understood for cost considerations, but there is still space to improve the layout to reduce the size;
2, the power adapter is really a bit large, it is not easy to carry but also easy to connect, it is recommended that the adapter is reduced or simply built in the machine;
3, dual speaker unit blaring direction, unless the rear projection or never get the correct direction of the voice, the proposed unit rear;
4, the projection process will still have a local virtual focus situation affect the viewing experience;
5, when playing a local picture will automatically stretch the picture to cover the screen.
Said later
As an audiophile, the main use of conventional bulb-type home theater projection, before the micro-projection did not have any good impression, cheap, poor quality, low brightness, low resolution, color like a mess and the like. After I bought Sony's micro-projection and used it for some time, my opinion changed a bit. There are differences in the use of micro-projection products and home-theater projection. The small size of the micro-projection system and its own system plug-and-play, as well as auto focus and other functions allow you to enjoy it in many places and in many convenient ways. The effect brought by the large screen, only need to open a device to see the program you want to see without using a bunch of switches to operate several remote controllers. Although it is not as clear and beautiful as a regular home theater as a watch video, but the perception is still much better than a mobile phone tablet and a laptop computer, but it is more convenient than a normal TV, whether it is smart or non-intelligent, and the price is more affordable. Whether at home or abroad there is a vast application space and user population, it is no wonder that it will sell so well in the country. This is by no means a matter of propaganda and gimmicks. Publicity can support for a while, but it has been selling for some years in a row. Is the result of user experience. But then again, as an audio-visual device, a so-called non-screen TV with integrated projection, speakers and player is true compared to a genuine home theater with full professional home theater projection, surround sound system and Blu-ray player. The difference in painting results is still very large. The two are more of a complementary, not a substitute, relationship. When you are lying in bed and want to watch a movie before going to bed, micro-investment is undoubtedly the more appropriate choice. If you do not have enough economic strength or environment to form a complete In a home theater, a micro-projection also allows you to experience some home theater fun. So for my test of the H1S, this is a very comprehensive and intelligent projection of all aspects of a mature, very suitable for the home as a general viewing device, simple and convenient, and good results. For audio and video enthusiasts who want to enjoy movies anytime, anywhere, and do not want to toss, they also need such devices. I often take the Sony portable projector to see things in hotels and even get a white sheet attached to the mountain. Bluetooth speakers just look like car cinemas. Especially now that WiFi is so popular today, it is tantamount to having a movie theater. If you can later have a smaller native 1080P resolution with its own battery system micro-projection is even better.
The evaluation is here, hoping to let everyone know more about the performance and use of this product, thanks for reading
