The color is accurate so that the eyes will not be on the projection

In 2015, the mini-projector thrived, and the various princes divided the video fat. Some Internet projection companies such as Kizemi, Divine Painting, Cool Music, Nuts and other brands have obtained large sums of money. The introduction of products has been one after another, and waves have followed, making the miniature projection market booming. I have also reviewed several brands of micro-projections and found that under the same resolution, with almost the same lumens, the reduction of projected screen colors will deviate from the original. After listening to so many brands, has it forgotten that a veteran projection brand? Yes, BenQ! In fact, when the author was young, oh no, it was a younger time. BenQ Projection has always been synonymous with high-end projection. Of course, now projection has spread to millions of households. BenQ also launched a color reproduction accurate i300J in 2016. Smart micro projection, here's to share BenQ's experience with this new product.

The rectangular packing box adopts a one-way removable type. A white paper jam shell is set on the outside of the cardboard box. The LOGO of the "fun ball" is in the center of the white paperboard, and the side is a gradual change of the yellow origin. Concise fashion is the author's first impression of the BenQ i300J intelligent micro-projection packaging.

Open the box, three-stage packaging design, left and right sides for the accessories area, the middle for the micro-cast. Note that the micro-cast surface is waterproof, shock-proof and scratch-proof. It is also packed with a certain thickness of foam bags. It has a good effect on protecting the host.

BenQ i300J projector accessories quite satisfactory, from left to right overview: power cord, power adapter, projector host, remote control, Micro USB charging cable, product warranty card, user guide and remote control code guide. The author found that BenQ was very careful and thought about the situation that the projector may not match the remote control after booting. However, although the author used it for the first time and did not encounter such a problem, but for this situation, the method to solve the problem or the key points can be taken into consideration. Like it.

BenQ i300J micro-projection remote control is white plastic material, both ends are semi-circular, so the shape is very rounded. The bottom of the design of the Micro USB socket, built-in rechargeable lithium battery. There is a small detail, the author found that the top is also designed lanyard hole, easy to hang in the hands will not be found, but unfortunately the accessories did not see a lanyard.

The panel of the remote control also uses a round button, which makes the remote control more rounded and lovely, and the grip in the hand is also excellent, and can be grasped with one hand. Although there are more buttons on the remote control, the benefit is a radish pit, each button has a role, can be a key to direct. At the same time the author also found that the bottom of the button is a key to clean function buttons, as long as a light press, you can clean up the projection of memory, eliminating the use of unnecessary system software resources. Although it is not a metal material, it is light and non-slip in the hand, and it won't be cold in winter. At the same time, the success rate of the keystroke is almost 100%. No false pressing is found. The remote controller is generally viewed as a grip and functional design. It's pretty good.

The BenQ i300J smart miniature projector has the same appearance as the remote control. The corners are almost semi-circular, more comfortable to hold in hand, and do not feel heavy. The original shell is not a metal material, but the use of engineering plastics, so the whole machine is only 900g, it can be said that fully meet the requirements of micro-investment. The front left side of the projection is the projector's key, the projection lens. In order to protect the lens from dust, a sliding dust cover was also designed. The ventilation hole on the right side reminds me of the gradient design on the outer packaging. The original material is here.

The back of the projector has a fine metal mesh cover, which contains two 8W speakers. At the same time, it has a considerable cavity design, as well as professional high-fidelity sound chip, making it easy to listen to music and watching movies. The slightly upward tilted 13Â° design takes into account the listening needs of the sitting and standing positions when the user views the projection. The projection sets the switch key on the front, and it is interesting to click it twice before it can be turned off.

The left side of the projection is designed with a power jack and a manual focus button, and there is also a portion of the vent hole designed here. In addition, I would like to talk about the feel of this manual focus button, I believe that experience is the fastest in the manual focus in focusing to reach the exact position, feel the most comfortable and smooth one, not one.

The right side of the fuselage is the interface area, in addition to generally equipped with HDMI interface, USB2.0 interface, LAN broadband interface and audio output and headset interface, actually there SPDIF optical digital audio output interface and USB3.0 high-speed interface. This will be very smooth for watching large-volume, high-rate video in U disk or mobile hard disk. Digital audio will be output to high-fidelity speakers to enjoy more clear and detailed sound quality. By the way, the cover on the side is really good. It can be perfectly closed without any effort. It shows that the mold is doing very well.

At the bottom of the projection, three ventilation holes are designed and three rubber feet are placed in a triangle to provide a stable, non-slip surface. A round screw hole is also provided between the bottom two foot pads to facilitate the support of the tripod. Several white dots should be designed to visually block the screw holes. However, the golden body shows a white point, and some are not coordinated. Fortunately, the bottom is almost invisible.

Some people may ask, if the screen is high, and the projector can only be placed on the table to show how low? BenQ also took this issue into account. To design a circular pad as a screw, it can be adjusted according to the actual situation to meet the needs. The screw-type floor mats are the same as the fuselage and are made of engineering plastic materials. Although they look slimmer, they are practically used without fear of being destroyed.

BenQ i300 projection lens uses 6 pieces of optical glass. The advantage of glass lens is that the physical properties are more stable at high temperatures, which contributes to the stable and clear image output. The light source adopts LED, and the color is more pure than the traditional light source, and the longest life can reach more than 20,000 hours. The resolution of the projection is 1280,800 for mainstream micro-casting, and 400 ANSI for lumens, which can still be met for daily use.

After the appearance is introduced, let's take a look at the system UI of i300J micro-projection! Without exception, the system is deeply customized for Android, which is an excellent extension to the software. So let's first boot to see if this projection system is humane? The first is to choose the location of the projector. It is very intuitive to display in the form of pictures, and four different ways of placing the projection view. Then select the language and WiFi connection options, enter the wireless routing password, you can connect to the network directly into the system.

The content provider that originally cooperated with BenQ was the interconnected Octagon. After the author's understanding, it was one of the 7 Internet TV content licensesâ€”the network television license owned by Southern Media. Enter the main menu and see that the page design uses Microsoft's magnetic design, simple and not fancy. The top left corner is divided into four menus: recommendation, category, application and setting. In the recommendation, the user is most likely to use the most frequently used software and the latest movies, TV drama content. In the category, there are six categories, namely, the latest, TV drama, movie, variety show, children, and animation. From the point of view of the content, it can meet most of the needs of users.

In the app section, the cloud audiovisual software is displayed by default, and the system default software can be added to the application main menu in all applications. The author found that, according to the illustration, the free year card of the video content can also be watched, and more latest and hottest movie and television shows and variety shows can be watched.

Point to open a game software - Feizhi game hall, found inside the game content is quite a lot, from plant vs zombies to King of Fighters 97, download can play. However, I tried a few games, all require the game handle to perfect control, but fortunately the projection is a USB interface, connect the game handle to play the game so easy.

Looking back at the content, on the content of the movie, the relatively new and popular movies were marked with 5 yuan. TV dramas have found Korean dramas, American dramas, and domestic dramas. High-definition theaters and previous movie menus have been repeated. This also shows that most of the content in movies can reach high-definition versions with 1080P resolution.

In the 3D area, there are only four videos to be provided, but all are considered to have outstanding 3D effects, such as â€œFantasy Rafting by Juvenilesâ€. Unfortunately, the accessories do not have the configuration of 3D glasses. To see the 3D blockbusters, BenQ's active 3D glasses must be purchased separately. The expenditure of one hundred yuan is not very expensive either. There are movies with Dolby sound, suitable for viewing under stereo conditions. Entering the TV drama section, I discovered that there is a "Ode to Joy," which is currently on the air, free of charge, updated quickly, and the effect of actually watching color quality is very good.

Under the Settings menu, there are two options for skinning and more settings. In more settings, including network settings, regional time, user feedback, system settings, system updates, these six options. The author is concerned about the degree of ease of upgrading the system software. At the same time, there are two kinds of network updates and local updates. Click on the network upgrade, um, found that it is the latest version, if not the latest, the author will not let go, because I do not upgrade uncomfortable, typical obsessive-compulsive disorder patients.

In the About menu, you can see the projected hardware and storage information. I found that the i300J micro-projection uses a combination of 1G memory + 8G storage space. Although the hardware parameters are relatively shabby compared with the current mainstream mobile phones, because the micro-projection feature is not a larger memory display will be more clear, the color performance is more accurate, which requires actual use to prove that it is appropriate. The system also comes with a security manager program that can manage the software that is started automatically.

When playing, in fact, through the MENU button in the remote control, on the left side of the screen, you can call up the detailed setting menu for adjusting various parameters of the projection. The default is in the volume adjustment menu, here I think the volume adjustment must be adjusted out of the menu to adjust, more inconvenient, should be adjusted directly on the remote control, I hope the next system upgrade can improve this problem. There is also a setup menu at the bottom of the menu, where the author is most concerned with automatic trapezoidal correction and manual keystone correction mode. In actual use, automatic trapezoidal correction can adjust the projection screen for most of the upward and downward viewing situations. In the case that a few automatic corrections are not perfect, manual correction can be used to make the screen suitable for human vision, which is very easy to use.

At the top of the menu, there are projection image modes, which are divided into 5 modes: Custom, Bright, Vivid, Game, and Movie. Different modes will have different color temperature, brightness, contrast display.

The BenQ i300J micro-projector has also set up a wireless projection function. As long as the mirroring function is set in the menu, WiFi can be used to transfer the video screen on the mobile phone to the projector. For example, open the phoenix video app on your mobile phone, find the favorite â€œsmiley faceâ€ talk show program, click to play, select the screen shot in the software menu, you can find the name of the projector Scifly7523, the screen can be realized in a flash.

Some people worry that it is very difficult to install the APP. I have used several projections, either to crack or to install software through mobile phones. This is very inconvenient. Fortunately, the BenQ i300J does not need to be so troublesome, the author to install when the shellfish market software, for example, as long as the APP software is downloaded to the U disk, insert the USB flash drive to find the software, you can successfully install, download the user's favorite video projector / TV software, Very convenient.

The author found that whether it is a projection or 4K resolution smart LCD TV, throwing away functions and systems, in fact, the most important thing is to display the quality and color. Let us first look at the picture quality of the BenQ i300J smart micro projector. Before this, the author was ignorant, thinking that the picture quality is clear and delicate, which is a very good picture quality. In fact, the correct reproduction of colors is also very important. So first we need to understand what is the concept of D65 standard color. The answer given by the International Commission on Illumination (CIE) is: In the case of a typical daylight with an artificial color temperature of 6500KÂ±200K and a color rendering index >96, the light source seen below is called the D65 standard light source. The D65 standard light source is very similar to the daylight illumination in most cases, and its spectral power distribution is also very similar to real daylight, which is the most familiar light. Now many industrial productions, printing and packaging, and photography all use this color as the standard. The light bulb in the light box of the author's home is in line with this D65 color standard, so the movie that comes out is very eye-catching. Understand the color concept of D65, and take a look at BenQ's claim that it can reach the D65 color standard i300J micro-projection in the color of the picture What are the highlights?

The above two beautiful pictures are used to test the contrast. Under normal circumstances, many projectors and TVs do not achieve the best contrast in the factory default state. Many users with high requirements on the screen will use test discs such as â€œHiVi CASTâ€ and even use professional instruments (such as Starscream). ) Adjustment screen. BenQ i300J micro-projection factory default, white contrast is very satisfactory, beyond the author's expectations. It can be seen that the beautiful woman is dressed in white, and the silhouette on the white background is very obvious and can be discerned at a glance. The black contrast is less white and requires careful discrimination to see the outline details.

Then through a gradient map to show the gray gradient reduction ability of the projection. It can be seen that it is almost impossible to tell whether the color depth of each block is different. It is only near the 19th color block in the upper left corner that the naked eye cannot discern. The results of the previous test of the author of the PPTV, Lenovo 17TV and other 4K television screens said that the performance is much better, it seems that the gray gradient ability is not related to the level of resolution.

In the daytime low-light state, 400 ANSI lumens are indeed more difficult to perform on the projection screen. Although it can be seen clearly, there is indeed a lack of detail. Under this circumstance, the author believes that watching videos is really difficult, but if you play PPT, WORD, and EXCEL file forms as a mobile office environment, the screen performance will be no problem.

In the dark environment, the BenQ i300J micro-projection screen is very eye-catching. Although the standard resolution of the projection is 1280x800, after connecting the PS4 game console, the detail can be perfectly displayed for a game screen that shows 1080P resolution upwards. First of all, in the high light part, the phenomenon of overexposure is basically not seen, and there are sufficient levels of display in the shadow part, making the skin on the arm sleek and shiny, and the dust on the skin is more vivid. Judging from the color of the picture quality, BenQ's algorithm control is indeed a technological precipitation style of a 20-year-old factory.

The picture seen at a distance of 3 meters is almost grainy. Only after the picture is magnified by 100%, the graininess of the picture is not noticeable. It is only because the relationship between the game console and the finger can be seen at the edge of the finger. Jagged, the transition is not natural. This is due to the fact that the resolution of the projection is not enough to affect it.

The author used a Nikon D750 full-frame camera set for automatic white balance shooting, through the original image of the 6 groups of images and projection contrast (the original image on the left, the projection image on the right). It can be seen from the distance of about 3 meters from the white wall that the picture quality is good and the details are clear. It may be because the Nikon camera's white balance and its sharp color feature enhance the contrast and vividness, and it is more likely to please people's vision and make the picture more vivid and more durable. Compared to the polar meter projection, the detail quality of the picture is more exquisite, the true reduction of the color is more real, and the picture quality is obviously higher. Judging from the quality of color reproduction, it is the 720P resolution projector that I reviewed and performed best. None of them.

I never thought of using a PS4 game console for evaluation, because I never thought it was projected. The delay is very severe and I can't basically play smoothly. In the spirit of not toss and die, or with the BenQ i300J smart micro-cast to experience.

The selected game is a beautiful fighting game. Of course, there is no free download in the Bank of China and it is necessary to swipe in a backup package of Hong Kong clothes before it can be downloaded and used for free in Hong Kong clothes. Everyone must remember this little secret.
