preface

With the development of science and technology, balance cars, unmanned aerial vehicles, and projection are no longer top products, but gradually enter into thousands of households. LED projection is the fastest growing projection in the last two years. Both new manufacturers such as Papa, brick, nut and LED old brand manufacturers such as Kuletv and Jimi have developed to a certain extent and accumulated capital and technology. Today, we bring you a Coole S3 projection, which has raised 11.39 million yuan in JD's crowdfunding, and is also the projection with the best brightness among LED projections. Yes, you are right. There is no one right now. Let's see how this projection works!

Appearance appreciation

Kuletv projection is divided into Q series, X series and S series. Q series is mainly portable, and the product is also very small. X series and S series are mainly for home use. Mid term S series is the high-end product of Kuletv. This time, the Kuletv S3 has revolutionized both in appearance and performance. As shown in the figure below, the S3 body is black all over and made of mirror material. At the same time, it is no longer a rectangle like X series and S2, but a square.

The back of Kuletv S3 is made of black plastic, and a common M1/4 screw port is set in the middle, which is common with the traditional camera tripod. If you have a friend with a tripod at home, you can use it as a support for S3 at any time. In addition, the four floor mats of Kuletv are designed as removable floor mats. Users can easily replace the floor mats, or even replace some long floor mats, so that they can easily use the tea table in the living room at home.

Kuletv S3 is also rich in interfaces, including mini AV interface, dual HDMI 2.0 interface, RJ45 network interface, dual USB interface, 3.5mm headset interface/coaxial audio output interface, and built-in wifi and Bluetooth module. However, USB3.0 has been integrated in Kuletv X5. I don't see it in S3. It is a pity for some users who like mobile storage.

The biggest highlight of Kuletv S3 this time is the 1000-1200 ANSI lumen led bulb. It adopts 800P chip of 0.45 ″ DMD instead of 1080P chip of 0.47 ″ DMD. This is also a very depressing point for many cool fans to wait out. However, as a projection effect, the resolution is one aspect. In addition, the brightness, contrast, drive circuit, optical resolution of the light engine, as well as the actual use environment, the projected image and viewing distance will affect the image quality. Later, let's experience the specific effect of this 800P projection.

In terms of the packaging of accessories, there is not much change between the Kuletv S3 and the Kuletv family's products. All kinds of boxes contain different accessories. The uniform black dress is also a feature of Cool LeEco.

However, the remote control of Kule TV S3 is different from its X5 and other products. F+and F - buttons are added to the remote control for manual focusing. Of course, Kuletv has its own autofocus function, and these two buttons are basically useless. The other one is a voice button at the bottom, which supports voice input. However, the accuracy rate needs further optimization.

Features

Kuletv S3 supports voice recognition. In the version we got, we tried voice search, but the experience is not very good, and the recognition rate is not high. This is also a major difficulty in voice input at present, whether it is a mobile phone or any other recognition rate is not high. In addition, the voice operation of Kuletv S3 is also very simple. Just press and hold the voice key on the remote control, and then the voice input can be turned on. When voice input occurs, there is a corresponding prompt at the bottom of the screen.

The auto focus function is a major feature of Kuletv S3. Those who play projection should be very clear about how painful it is to focus manually. When the projection distance changes, you need to adjust it. When you take it out, you need to adjust it. When you see a movie collectively, you need to adjust it. Even when a group of people are often embarrassed, they are still focusing there. After a long time of adjustment, everyone still feels that it is not clear enough. Kuletv S3 helps users solve this problem. As shown in the figure below, during the whole startup process, Kuletv S3 starts to focus automatically. After the startup is completed, the focus is also completed.

Kuletv S3 also supports gesture recognition. There is a gesture sensing module on the top of S3. Users only need to slide this part up, down, left, right, and then operate the corresponding menu. This function is no longer available for friends who are hanging from the house (are your hands that long when hanging from the house), but it is very good for friends who usually have meetings and work a lot. Is it very arrogant to use this function for PPT page turning? In terms of gesture recognition sensitivity, there is no need to worry about it. It is very sensitive and can sense normally even in dark environments.

System UI experience

In terms of the system, Kuletv S3 is equipped with a self-developed UI, which is very simple on the whole. The main interface after startup has only four large menus, and the next row of shortcut buttons that can be added by yourself. The four menus correspond to the functions of watching TV and movies, listening to music, working and downloading applications. Users can perform corresponding operations directly through these four menus. (Note: the image quality of GIF pictures will decline)

In addition, third-party applications installed by yourself will be arranged in a page on the right, and a page will be automatically added when the page is full. Overall, it is very simple and convenient to use.

Although the system has its own movie and app store, I think the integrated movie and app are very common. The movie and app integrates the content of a company (no name), and a large number of movies need to be paid. If you are a local tyrant, please ignore it. If you want to watch TV for free, you can install other apps to watch movies. There are many choices. In addition, the application market is not complete, especially the classification in the game is too chaotic. It is recommended to download sofa butler or shell.

Experience effect during the day

Kuletv S3 is known as the "projection that can be seen in the daytime", which is justified by actual measurement. As shown in the figure below, when opening the window and opening the curtains in the daytime, the picture obtained is very good. The clarity is very good, and it can match the brightness of 1000 lumens.

Night experience effect

First of all, let's feel the picture when the video is played at night. As an LED projection, Kuletv S3 is really amazing in terms of brightness. At night, play a power supply, lie in bed, and enjoy the good time after a day's work. In addition, the visual angle of Kuletv is also quite good. As shown in the following figure, two GIF pictures are specially made for you. When playing the video, the effects from different angles are different.

Effect comparison of live shot/original picture

The above dynamic pictures have a great loss in image quality. Let's compare the static pictures. Below is the comparison between the projected picture and the original picture. You can refer to the projection effect. Overall, the projection effect is very satisfactory.

Document Experience

Kuletv S3 is equipped with 0.45 DMD chip. 0.45 DMD is an interpolation product. On the network, the effect of diamond arrangement is far less than that of rectangular arrangement, especially in text. The following tests the situation of browsing excel, pdf and word with Kuletv S3. Due to its own performance, Kuletv S3 loads these documents slowly when opening them.

As far as the actual launch effect is concerned, Kuletv S3 can fully meet the requirements in terms of use, and the text display is also very clear. For fans who like tossing, comparing the different projections of diamond and arrangement, we can find that the rectangular arrangement is more smooth and flexible in terms of font. Incidentally, the gossip: the next generation of Kuletv S3 products will be crowdfunded in November, and the optical machine still uses a 0.47 1080P DMD optical machine. They will perform better in detail.

3D effect experience

The projection of Kuletv series supports 3D playback, and the official has special shutter type 3D glasses. Glasses and charging use, compared with ordinary use, sound very high-end. Since the machine itself has only 16G storage, and a 3D movie is basically more than 10GB in size, it is better to have a mobile hard disk or home network storage environment if you want to watch 3D video. This looks convenient. In addition, the 3D effect is very good. During use, as shown in the figure below, you need to press the voice key on the remote control, and then select left and right. The picture will become blurred, and you can watch it with glasses.

Video playback capability

Smart projectors now have an Android system built in, which makes it convenient for users not to connect external video sources in their daily use. Of course, more systems will naturally test the system. Here we have tested videos with different image quality for your reference. As can be seen from the following table, there are still no major problems in video parsing. Android players are good at both hard and soft solutions. However, during the test, it was found that both 4K and 1080P video in mp4 format have only sound and no picture. However, this problem does not exist on the Kuletv X5. We tested the player that comes with the system, the popular Xiaobai series player on the box, and the universal decoding MX player, all of which are the same. It is hoped that the optimization process will solve this problem in the later stage.

Game experience

The configuration of Kuletv S3 is 1GB RAM+16/32GB ROM. At present, this configuration is really low, and can't keep up with most box effects. It is used to play arcade simulators. The game experience is not great, and playing games on a large screen is great. However, when it comes to some masterpieces, such as modern war games, the actual measurement will block frames. In this regard, I hope that Kuletv can keep up with the trend in the later period. After all, it is most convenient for users not to connect to external devices when they can.

Use tips

At present, the Kuletv S3, which has been used for a period of time, has personally experienced some tips that users need but are not very clear about. Here we share them with you.

1. At present, the OTA upgrade of Kuletv is basically useless. The firmware update of the forum is fast, so you can go to the forum to download the latest firmware.

2. The remote control is Bluetooth and infrared dual mode, and the switch on/off is infrared. The switch on/off can be normal only when the machine is aligned during use.

3. After the system is upgraded, the remote control must be paired again, or the key function of the remote control part will fail.

4. When playing 3D, it does not mean that the downloaded 3D format will be played directly, but when entering the play interface, you need to press the voice key on the remote control to switch 3D play.
   

summary

As the first kilolumen LED projection, Kuletv S3 is full of sincerity in all aspects, especially the auto focus function, kilolumen brightness, gesture operation, etc. The 3000 yuan level projection is superior. Of course, there is nothing perfect in the world, and there are still some problems with Kuletv S3 that need to be repaired by the manufacturer in a timely manner. The overall summary is as follows:

advantage

1. The kilolumen brightness can provide a good experience both in the day and at night

2. The auto focusing function solves the awkward situation of manual focusing.

3. Gesture operation, business use is full.

4. For the same type of product, the projection screen is larger when the same example is given.

shortcoming

1. The OTA upgrade is basically a device. I hope that when the new firmware is introduced, the OTA can be launched simultaneously.

2. It is hoped that the upgrade package can be provided at the same time during the upgrade process. Otherwise, a firmware update is equivalent to a system refresh, and the user needs to reinstall all the software.

3. The integrated software in UI aspect hopes to be more user-friendly, and the integrated software aspect basically needs VIP to be able to watch.

4. The new version of firmware provides the user with a user storage space and the name is Insdcard. After checking, it is found that the firmware type contains a sdcard folder, but the user does not have any permissions and cannot view any of the following files. It is hoped that the default name of the space provided to the user will be changed to sdcard, otherwise many software only recognize the path sdcard by default, resulting in software errors.
