After several years of low-key development, the micro-projector began another round of eruption from last year. The technological accumulation of major manufacturers over the years, coupled with the upgrading of DLP chips, a new generation of micro-projection in the brightness, resolution and other aspects have been fully enhanced. And the micro-investment market also reflects a phenomenon that can only be reflected in the rising market, that is, the differentiation of products, and the major names brought by the major manufacturers in the new year have brought about “the appearance of names†from appearance to performance. Big differences in the product, so that the discussion and collision between them become more interesting. The micro-investment Hengping products include Nut J6, Zimi X5, Divine Dawei, and Micro Whale F1. They are the main high-end micro-projectors that are listed on the market this year. They have a very significant brightness. Promote. In this cross-review, what kind of actual performance they will have, is really looking forward to! In order to further reflect the impartiality of Hengping, this Hengping will add live links, inviting the big coffee to judge the quality of the projector, and get a more objective purchase reference! Micro-projection design Compared with commercial models, as a home micro-investment in the appearance must be more sophisticated, able to "get out of the hall to get into the bedroom," with stylish and beautiful shape into the modern home. Then, how about the appearance of the four micro-investors participating in the Hengping? Let's take a closer look. The painting of Dawei is the flagship micro-investment of the latest listing this year. The angular shape is more atmospheric, and the body is dazzlingly white. The silver-gray god painting LOGO is particularly eye-catching and the semi-circular front-projection “big-eye†lens is added. A bit playful. God painted a large body measuring 196mm x 196mm x 50mm, with a net weight of 1.35kg. The redesign is still focused on taking the thin line. It can be put into the storage compartment of the TV cabinet flexibly, and it is also more portable when traveling. Let's look at the micro whale F1. The glacier gray "racing" temperament is stiff, and the drawing process reflects the high-end texture from the details. "Less is more" design language is also in line with the popular trend of minimalism, the body surface does not have too many buttons and decorations, you can also match a variety of home improvement style. The body measurements are 210mm x 200mm x 50mm, and the net weight is 1.2KG, which is as good as portraying Dawei in portability. The Quartet's M1 H1S style is different from the previous two models, but it is more closely related to the definition of a home projector. The LOGO and bar buttons are located at the top of the top of the body and are all eye-catching. The front and both sides of the fuselage are covered with metal mesh cover, cleverly hidden the horn and air inlet, enhance the overall sense, especially the positive Harman Kardon logo highlights the sound quality. The meters of the H1S reached a height of 202 x 202 x 135 mm, a net weight of 2.1 kG, and the volume and weight were clearly on a step. The shape of the last nut J6 is also quite unique. It is much smaller on the front than the H1S. It is mainly a rectangular electric lens door and a remote control signal receiving window. Slightly rhombic side metal, all over the heat dissipation air intake, also marked with a concentric circular pattern, the touch power button and the indicator light are hidden under the silvery white top cover, the closed state is red light, and after turning on, it becomes white light. Nut J6 measurements 208 × 133 × 108mm, net weight 1.54KG, slightly smaller than H1S. It can be seen that although these four miniature projectors have their own characteristics in appearance design, they all can be well integrated into the home. From the basic positioning of home entertainment, there is no problem. On the other hand, the volume and weight of the H1S are slightly larger than those of the other three models, and they are not as good as other models in terms of spatial freedom at home. More appearance details Lens For a projection product, the "eye" lens is one of the most important components. The lens part of the painting of Dawei was designed to be very characteristic. The semi-circular border was used to protect the lens. Its main lens uses a high quality coated glass lens for better light transmission. There is also a “secondary eye†on the right. This dual lens design allows the DaVi painting to accurately touch and automatically focus in real time during the projection process. These features will be further elaborated below. The frontal part of the micro whale F1 looks smoother and has nothing but a simple modification. The coated glass lens it uses is also excellent in light transmittance, but it is not equipped with a lens cap. Fortunately, the lens uses an in-line design that can protect the lens to some extent, and it is not easy to get dust during use. Both the H1S and J6 lenses have protective covers, but the H1S lens cover switches require manual adjustment. The H1S lens adopts a scratch-resistant, high-transmittance glass coating lens, but since the lens is not embedded, it is best to close the lens cover when not in use, so as not to contaminate the lens and affect the picture quality. The lens of the Nut J6 is not only deeply buried, but it also incorporates a very rare electric lens cap that can be opened and closed automatically when the machine is turned on and on. This is really convenient for the user and reflects the design intentions. interface As a media interface to connect with the outside world, a rich interface design allows users to use projection more flexibly and conveniently in daily use. Although the mini-projectors participating in the evaluation are congenitally limited due to the size of the body, they are not comparable to the projectors in terms of the diversity of the interfaces, but they are not without common interfaces such as USB and HDMI. The gods painting the rear of the Granville fuselage interface is relatively rich, dual USB2.0 interface, dual HDMI interface, LAN port, SPDIF digital audio interface, headphone jack and DC power interface, ä¹–ä¹–, and large home projectors are not much better Let's go. The number of ports of the H1S HMI is exactly the same as that of the Dawei, but it is worthy of its size, but one of the USB interfaces has been upgraded to 3.0. The nut interface has one less HDMI port than the H1S, which has little impact on the average home user. In contrast, the interface of the Micro Whale F1 is the simplest. The design of a single USB is not impossible for home users, but the scalability is still affected. Base The bases of all four projectors have rubber feet, which can reduce the impact when placed, and they can also play a non-slip effect. It is worth saying separately that the paintings of Dawei, the whale F1, and the nut J6 all have brackets at the bottom. Among them, the interface spiral of the Dawei painting is the most reasonable and the depth is enough, and it can be closely attached to most cameras on the market. Together. The other two types of screw holes may be due to insufficient depth, and they are slightly rickety after being placed on a tripod of the camera. It is estimated that it is necessary to use special brackets for micro-casting. The special meter is H1S. After purchase, you can receive the transfer tray with the serial number for free. The bracket interface is on this tray. Also from the bottom it can be seen that the Polar Meter H1S is equipped with a Harman Kardon Speaker. Remote control with different performance The colors of the four remote controls are different, and the functions are very different. The "Shenbi" remote controller equipped with the DaVi painting uses a 1000mAh** ion polymer battery with a relatively high cost, and the standby time is longer. The powerful "Shenzhen" button with less powerful functions integrates voice functions, and it can also achieve "air-to-air touch." The small whale projection F1 comes with a Bluetooth remote control that looks familiar. It turns out that the Bluetooth remote control of the Mini Whale TV is exactly the same. Black skin texture, semi-arcuate design fits the palm, holding a good feeling. Dot 12 key minimalist design, control experience is fairly flexible. The all-metal bluetooth remote control used in the Himi H1 can also be charged. The response is very sensitive. The 11-button layout is adopted and the voice function is supported. Nut J6 uses a plastic infrared remote control that needs to be aligned with the host. 16-key layout is now rare, more 3D button and focus button, but so many buttons even save the voice button, can not help but say little regret. System Experience Currently, there are two types of micro projectors in the market: smart micro-projection and non-intelligent micro-projection. The four micro-projections that participated in the Hengping review are all based on the Android operating system developed by the smart operating system, wired or wireless connection After entering the network, users can directly bring rich audio and video entertainment projects. Dawei's system interface is divided into five parts: homepage, theater, application, input, and setting. It is almost easy to get started with simple clarity. The virtual touch technology independently developed with Divine Painting is very smooth to control. In terms of content sources, users are also provided with fresh movie and TV drama resources through regular updates. The painting of Dawei was built on the CIBN network TV + Youku video dual platform to build a genuine video resources, and CIBN is the seven major Internet TV licensees recognized by the country. It is very powerful in both the quantity and quality of film sources. In addition to the "traditional functions" of the projector, the painting of Dawei by the gods is based on the "air-to-air touch" technology to achieve many new gameplay. For example, the “Love Painting†function exclusively developed by Divine Painting is an innovative function that is different from all projectors. It is a new game played with the technology of “air-to-air touchâ€. Parents can use this to complete a picture with their children to create a parent-child interactive experience. With this feature, the child can get rid of the problem of painting on the white wall with a watercolor pen, to protect the clean and tidy home wall. Polar meters H1S uses a GMUI system based on the Android system depth customization, interface design is also very simple and intuitive, divided into film and television, music, film and television, music, games, applications four major items. In addition, the company also strategically cooperates with Mango TV, so users can now enjoy 24 months of mango VIP membership services. The system used by the Nut J6 is also an exclusive custom TV system. Most of the content is directly displayed on the main page and it feels more comprehensive. In terms of video content, Nut J6 mainly cooperates with iQIYI, and can share iQIYI related video sources. Of course, VIP is the most popular resource. Microwhale smart projection F1 system is WUI2.0, which is roughly the same as the system of micro-whale TV. Since there have been many TVs connected to a few micro-whales before, the system is already very familiar with it. The fluency and detail design are worthy of recognition, and the follow-up will continue to be optimized and upgraded. Waterfall flow page layout, all the content is presented on a page, only need to press the up and down keys on the remote control to see all the content, common content sections or third-party software can be customized in the first screen , you can quickly find the content you want to see. Focusing ability Whether the screen of the projector is clear and whether the focusing ability is good is very important. In these four projectors, DaVi has the full autofocus function, including automatic focusing when the camera is turned on, defocus when the lens is displaced by external force, and autofocus after the lens has been defocused after long-term operation. Autofocus is a patented technology of Divine Image Technology. After three years of sedimentation, it developed the "One Second Extreme Focus" technology and it can really make the blurred images reappear clearly in one second. In addition to auto focus, DaVi can also perform very accurate auto trapezoidal correction, which brings great flexibility for installation and use. Micro whale projection F1 does not use auto focus, manual focus method has two shortcuts, one is to press and hold the remote control on the voice button to release the "focus" command, automatically out of the focus adjustment interface; the other is to click on the body power The [+] focus button on the edge of the button pops up the screen and then manually adjusts. In addition to the "manual focus", the Polar Meter H1S can also perform "auto focus". Of course, its auto focus can only be considered "semi-automatic" compared to the divine painting. It also requires the user to take the initiative to operate it. The quickest way is Options popped by voice key. After the actual measurement, manual focus mode can also get the best clarity, which is a little troublesome. The nut J6 can only be manually focused as with the micro whale F1. When the focus is on the screen, a circular assist focus pattern appears. The most clear display can be adjusted by using the [+] [-] on the remote control. However, trapezoidal correction can be done automatically, the effect is not bad. From the measured effect chart, these four projectors have good focus accuracy. Of course, the focusing modes are different, and there are two major schools, automatic and manual. For most home users, it is always best to be able to quickly and accurately "automatically" focus as well as automatic keystone correction. One big picture quality competition: brightness PK Brightness is the biggest dilemma in the quality of home projectors. In the past, projectors could only be used in small dark houses, and the experience was very affected. The four intelligent micro-projections participating in the Hengping evaluation are all based on high brightness. The ANSI lumen values ​​are all in the thousands. What is necessary is to allow the user to use it in a more natural state, even if it does not pull the window during the day and open it at night. With the ceiling light, the picture will not be too white. God draws Dawei light on the environment Micro whale F1 lighting environment Extreme meter light environment reward map Nuts on light environment reward map Next, test the actual ANSI brightness value. The ** gold of the highlighted micro-projection is still more reliable with the data. Of course, the office environment will have a certain influence on the brightness of the micro-projection, and there may be a slight deviation from the actual value. The measured results are as follows: God painting brightness measured Extreme meter brightness measurement Micro whale brightness measured Nut brightness measured The figure above in the meter is the minimum value of the ANSI brightness nine-square grid, which is nearly 100 LUX from the maximum. It can be seen that in the aspect of brightness, Dawei and Humi H1S are basically at the same level, and the small whale F1 and the nut J6 are at the same level. Limited by the test conditions and instrument performance, this value is only a relative reference, and the following will continue to focus on image quality. Quality Competition II: Color PK These four projectors all use LED-based DLP technology, which projects the image signal after digital processing. The resulting color quality depends on the joint efforts of the light source, the color wheel, and the DMD chip. Therefore, the four projectors have both the commonality of DLP projection on the image quality and their respective characteristics due to the differences in the components used. To shoot a screen shot that correctly reflects the DLP projectors such as Davies and Mito H1S, the shutter needs to be slow enough. If you use a so-called safety shutter, then you must see strange colors in various colors. The rainbow of the camera Eyes are much more comparable to human eyes. The 1/20 shutter is used for editing, and it is still possible to select the one with a more positive color after shooting multiple shots. Let's take a look at the three primary color PKs of these four projectors to see if their color accuracy and distribution are uniform. All of these pictures are real shots. The original taste has not undergone any post-processing. It can be seen that the solid color performance of the four projectors does not show too much deviation, the color distribution is relatively uniform, and there is no obvious darkness at the corners. In contrast, the whale F1's solid color performance feels slightly warmer and the pure red performs very well, but pure blue is a bit too deep here. The polar rice H1S is just the opposite and it feels slightly colder. This is a standard side view of color and resolution, with which it can also be simple and intuitive to reflect the color rendering capabilities of the four projectors. The more the color area at the bottom left is able to present a triangle, the more “right†the color capacity is! It can be seen that in addition to the general performance of the green system, the performance of other series is still possible. In particular, the red and blue areas of the paintings of Dawei and Lami H1S are particularly correct. Let's take a look at the grayscale performance of the four projectors. It can determine the detailed performance of dark scenes and highlight scenes. The lack of grayscale performance can lead to the loss of detail in the picture. Comparison of God's paintings of Dawei (left) and Qiaomi H1S (right) Comparison of gray whale F1 (left) and nut J6 (right) God painting Dawei can accurately distinguish the darkest 4% The grayscale capability of the dark part of the H1S meter is second only to the Dawei painting of the gods, and 8% begins to distinguish more clearly. Micro whale F1 can also be differentiated to 8% Nut J6 is relatively weak, 12% began to see some The results showed that the four high-brightness micro-projections all possessed quite detailed performance capabilities. Among them, the divine detail ability of Dawei's paintings was particularly superior and it was able to distinguish 4% of subtle differences. Next, let’s enjoy a set of picture tours and movie screenshots to see the highlights of these highlight projectors. It can be seen that there is a certain difference between the respective “painting styles†of these four projectors. The picture of the Little Whale F1 is relatively warm. Of course, this is not necessarily a bad thing. It will give people a more lively feeling when portraying people. The dazzling brightness of God's paintings is indeed extraordinary. It is worth noting that the brightness value of the four products is the highest, and the background of the dark areas can also be displayed in a more complete manner. The screen resolution of Polar Rice H1S and Nut J6 all reached 1080P, and the brightness level was relatively high, but there were still some differences in color. The screen of H1S is rather cold, which is in stark contrast to the small whale F1. As for the Nut J6, the biggest problem is the relatively weak performance in the dark. The details of the right picture of the "Raytheon" and "Godzilla" have been lost more. If you don't care about it, the color expressive ability is remarkable. . Silence and fever It seems that the new generation of high-brightness projectors has made great progress in quality compared to the products of the past. However, a projector must be able to operate stably for a long time. In addition, the noise of the projector also has a certain impact on the user experience. Can these four micro-projections handle the contradiction between noise and heat dissipation? Immediately below to reveal the relevant situation. Polar meter H1S powerful cooling mode noise Polar meter H1S general cooling mode noise Nut J6 strong cooling mode noise Nut J6 general cooling mode noise God draws David noise Micro whale F1 noise In the previous test session, it was felt that these projectors performed very well on the mute effect. After actual measurement, their working noise is not much higher than ambient sound. Only when the Mi Mi H1S and the Nut J6 are in the strong heat dissipation mode, a more pronounced noise will be emitted. Noise value of four projectors after power on (unit: decibel) In fact, even if the powerful fan mode is to be enabled, it may be turned on after a long period of time in certain scenarios. For example, in the middle of the summer when air conditioning is not used, it is generally not possible. After more than two hours of experience, the editor used a thermometer to test the heat of the four projectors on the front, side, top and lens areas, respectively, and did not find hot temperatures exceeding 50°. Extreme meter H1S fever test (unit: degrees Celsius) Nut J6 fever test God painting Dawei fever test Micro whale F1 fever test From the results, in addition to the slightly higher temperature on the back side of the nuts J6, the heat levels of the other three projectors are very satisfactory. Even if the shape is relatively flat and the inner space is even more narrow, the paintings of Dawei and the micro whale F1 do not overheat after a long period of operation. It can be seen that the internal cooling design is mature and reliable. The temperature test of the nut J6 is performed under the condition of an automatic fan. In use, the user can also select a strong heat dissipation mode to cool down, but it needs to withstand a little noise. The temperature of each part of the four projectors after 2 hours boot: The temperature change curve of each part of the four projectors within two hours after power on: Evaluation summary Overall, these four high-brightness pico projectors have made considerable improvements in picture quality compared to the previous micro-projection products. After saving the portable mobile playback function, the display of the output screen is enhanced by greatly increasing the brightness. Just like the LCD TV, open the micro-projection in the brightly lit living room, comfortably enjoy the Hollywood blockbusters, micro-cast users "daydream" has been successfully resolved! The gods and dashes of Dawei's last netizens are concerned about the sale price. In these four projectors, the price of the micro whale F1 is certainly very affordable, but considering the advantage of Dawei painting in brightness, it can be said that the price/performance ratio is also Do not suffer. The most expensive Rami H1S is indeed expensive, although it and the Nut J6 are full HD 1080P models, but it is slightly better in terms of gray scale and brightness, making it also a good home theater select. The following specific reviews are made on each of the four products: God painting Dawei has the highest brightness in the four projectors, and the color performance is also quite good. It is no longer a wish for the user to open the curtains to watch the projection during the day. The volume of the projector is relatively small, there is no problem to put up a tripod or put it on the desktop, it is very flexible to use, and the automatic focusing mode makes its user experience greatly improved. Regardless of whether or not you have used the projector before, the painting of Dawei will be a good family big screen entry program. Little Whale F1 The micro whale F1 is quite satisfactory in this cross-review. There is no obvious place. But considering that it allows everyone to use high-brightness micro-injection at the most affordable price, it is worthy of praise in terms of cost performance. In terms of picture quality, this projection is slightly warmer. If you don't mind this, small and medium-sized apartment living rooms can still use it as an 80-inch projection screen. Polar meter H1S The high resolution brought by 1080P brings more fine picture quality, and naturally it can further increase the size of the projected picture. When the screen of the H1S is magnified to 120 inches or so, standing at a distance of 3 meters does not seem to be awkward. If the family living room is relatively large and the viewing distance is far enough, 1080P projection can be given priority. In addition to impressive brightness, the H1S meters are relatively sound-quality and are closer to home theater positioning. The more tangled place is that the picture is a bit cold, depending on the user's personal preference. Nut J6 In addition, the volume of a 1080P micro-nutrition J6 is relatively small, and the applicability at home is better. The intimate design of the electric lens is more conducive to protecting the lens and keeping it clean. In terms of picture quality, the advantages and disadvantages are prominent. The color is relatively accurate, but the grayscale performance is relatively weak, and the brightness is relatively unremarkable. Therefore, the details of the dark part of the movie screen will be lost, with some regret.
