Cool music seems to be pressing too hard.

What is the biggest difference between smart projection and traditional projection hardware? Is the light source! The traditional projection adopts the "bulb" principle of high pressure gas discharge, and the intelligent projection basically uses LED solid light source because of the light weight demand. Although LEDs have the significant advantages of low energy consumption, low heat generation, and long life, the brightness is also significantly lower than traditional "bulbs." Therefore, there have been smart projections of "seeing light dead" in the daytime, and it can be said that anyone strides through this threshold and anyone will fight for initiative.
This year's flagship product, the S3, was used in the last two weeks. It was called "Projection that can be seen during the day." Personal feeling, S3's design and development is very interesting, metal fuselage components, automatic focus, gesture touch, HiVi HiFi stereo and can be used as a separate speaker features Nabai's long, divine painting, extremely rice, nuts, etc. The best part of your friend's product has been reflected in the Cool LeTV S3, the most important thing is to make the national standard 1200 ANSI lumens, and have the biggest selling point. Below, we come together to experience this "wolf" smart projection product.
Cool music as S3's packaging is simple, black background with hot gold S3 and the ring pattern more eye-catching, unpacking only to find that it is the corresponding top of the fuselage design. Although the “Love Movie Love Life” copy on the side of the box is more literary, it is easy to think of this product as creating a private theater. The packaging protection is also in place. There are sponge cushions on the upper and lower layers in the box, a film on the host, and a small box for accessories. Fixing and shock absorption are not problems.

There is nothing special about accessories, conventional power adapters, cables, remote controls, and batteries. However, the power adapter is a little larger than the several projection power adapters used previously. Looking at the parameters, the original S3's power adapter output current is 7.1A, other intelligent projection is generally around 5A, it seems that thousands of clear and real need "horses grazing."
Cool LeTV S3 has an innovation in the projection method is a wall-mounted type, through the reflection component, can be used as a piece of art hanging on the wall, can also be used as a HiFi speaker, it must have a face value. S3's 2.5D bright paint plastic front, metal mesh é•‚ air frame, multiple arcs, 225mm225mm53mm square volume, so that the visual sense tends to be stable and generous, but also more suitable for integration into the home.
S3's slightly raised front is tightly connected with the metal middle frame, which is overly natural and has no abruptness. It also makes people feel more full. When the power is turned on, the front ring and LOGO will be lit, and it is regarded as the status indicator, and through the small 3D motion sensor in the middle, gesture touch can be achieved by sensing the hand movement. This function is considered a “spare tire” and you can realize its usefulness when the remote control cannot be found or has no electricity.
The mirror effect brought by high gloss paint is very good, but there are natural concerns about grinding and soiling. I used my nails to draw a few strokes on the mirror, and I couldn't see the scratches. It seemed that the S3's mirror hardness was OK. However, from the side perspective, you will still find a lot of fingerprints, and the front will feel less because of the reason of reflection. If you care about it, it is recommended that you always use a soft cloth to keep it shining.
S3 dot hollowed out the metal middle frame has the eye-catching effect, the metal matt and the top 2.5D high-gloss mirror set off each other, their texture is more prominent. At the same time, the metal material is not only beautiful, but also more beneficial to the rigidity and heat dissipation effect of the whole machine.

Cool Music regards the S3's lens slider as a switch, which turns on when the lens slide is pushed to the side. The small lens next to the main lens is a fully automatic focusing component that automatically detects the distance and angle between the S3 and the projection screen or the wall surface, automatically focusing and trapezoidal correction. In fact, whether it is a slide switch or an auto-focus system, these are all for the sake of simplifying the operation, and they are all optimizations and upgrades of the user experience.

Interfaces, S3 provides 2 HDMI, 2 USB, 1 mini AV, 1 3.5mm headphone jack, 1 RJ45 network port, and built-in WiFi + BT, can be external Bluetooth speakers to meet daily needs. In particular, there is an ANT interface, because S3 is the first company in the smart projection market to have a terrestrial digital TV DTM built-in. With an external antenna, you can watch high-definition TVs without a network. This interface makes S3 more practical. The main heat-dissipation window occupies half of the lateral area, and the metal heat sink is visually visible. The heat-dissipation effect is specifically tested at the back.
The way we use projection is generally a bracket and a flat. Cool music as S3 uses the national standard screw hole, common with the ordinary SLR tripod, and each of the four small feet can be rotated to adjust the height, to facilitate horizontal fine-tuning when lying on the table.

Intelligence is the difference of smart projection. Cool LeTV S3 is equipped with its own cool OS developed on Android basis. The whole interface tends to be intuitive and simple. The largest proportion on the homepage is “Television, Music, Office, and Applications”. The following are “Settings, Sources, Wireless Screen, File Management, One-Click Cleanup” and custom shortcut icons. The page is equivalent to the APP list page. The advantage of this design is that it can quickly locate the required function subpages, but it needs further optimization in aesthetics.

Content is the core. Cool music as the film and music are working with third-party content service providers, and the resources provided by iQIYI are not bad, popular film and television, variety shows, children's content are covered. A while ago, Youku, Tencent, and iQiyi announced cooperation with Xiaomi New Product Conference took up more than 80% of the time of video APP users. It can be seen that iQiyi is in the position of providing content. It is suggested that cool Leyi can provide users with One-year membership value-added services. Of course, if there is more content on demand, it can be downloaded and used through the application market. There is no difference with smart TV.


For obsessive-compulsive disorder, the process of manually adjusting the focus after each change of position is very tangled. Prior to this, autofocus has always been the killer for the divine projection. Now, Cool LeTV S3 also supports auto focus and dynamic real-time focusing, auto focus is no doubt the convenience, and dynamic real-time focus can be the perfect solution to the thermal expansion and contraction caused by the operation of the "heat out of focus" phenomenon, more conducive to the picture The overall clarity. In the actual measurement, the S3's autofocus response is sensitive, and the focus can be automatically completed within 5 seconds according to the position change. The following motion diagram is visually displayed, which is similar to the picture we see when automatically measuring the vision with glasses. To clear.
Of course, there is also a manual focus button of "F+, F-" on the remote control, which is also called "spare tire". However, the sound control function of the remote control is relatively easy to use, and the content of the remote controller is directly indicated. The cool OS will automatically perform the corresponding search recommendation. Moreover, the remote control supports infrared + Bluetooth in two ways, so there is no problem in operational sensitivity. However, the OK key is designed to be concave, although there is a certain anti-misoperation effect, but relative to the raised and down the left and right keys, the concave is too deep, the handle is not adapted, it is recommended to improve later.

Projection quality is fundamental. Cool LeTV S3 is equipped with the Texas Instruments 0.45 "1280 × 800 graphics chip and 64-bit A53 smart chip, Mali-T720 3D graphics engine, 1.2 projection ratio of 2.65 meters will be able to project 100-inch screen, for not on the physical 1080P or Unfortunately, the projection quality is not only related to the physical resolution, but also affected by factors such as projection brightness, contrast, color reproduction, and the projection environment, distance, etc. The S3 is equipped with an Osram P1A LED light source, designed and calibrated by an optical machine. The maximum can reach 1200 ANSI national standard lumens.As the saying goes, "A white cover three ugliness", we still look through the measured to improve the effect of thousands of brightness on the projected picture quality, there are pictures and the truth does not make too many comments, all pictures are It is real shot cutting without late.

The first one: three primary colors.
Second: color saturation and transition display.
The third: projection display in dark lighting.



The fourth, better light indoor projection display, in contrast to the third.


The fifth is a comparative display of projected and actual maps.
The sixth, brightness contrast display.
The seventh, sound test. When watching a movie, the sense of presence brought by giant screen is unmatched by ordinary television. Moreover, the built-in 28W Swans Hivi hi-fi speaker, sound level as much as desktop audio.
Eighth, temperature control test. After working for nearly two hours, the temperature of the hot air discharged from the rear heat dissipation window of the tester was about 51 degrees, the temperature at the top of the body was about 37 degrees, and the middle frame temperature was about 32 degrees, and the heat dissipation effect was excellent.
Taken together, Cool Music regards the S3's design as a synergy with the many advantages of its business partners, and it also promotes a large number of lumens, allowing smart projections to enter the thousands of lumens. “Projection that can be seen during the day” is true. Of course, S3 also has some areas for improvement. For example, it is recommended to optimize the architecture of the system and cooperate with more video sources and application providers to adapt more resources. For another example, it is recommended to increase the USB 3.0 interface to meet the needs of 4K and other resource transmission. Also, to further optimize the accuracy and speed of fully-autofocus, this highlight feature is highlighted. In short, watch movies no longer need to tighten the curtains, I like it!
