I have my own PaPa projector, and I believe everyone who has experienced it knows that the image quality of that thing is not satisfactory, so from the perspective of eye protection, it is basically in the situation of eating ash. I'm still looking forward to intelligent projection. I know the principle of "pay for goods". For example, this Kuletv S3, a machine with high brightness as its selling point, how does Kuletv actually perform? Let me have a look.

Part I: Appearance

The black simple box has nothing to say.

I simply opened the box.

The shape is round and square, and the body is surrounded by a circle of metal mesh cover strips. The appearance design is still very fashionable. The HIVI symbol indicates that Huiwei's sound unit is used. I don't know whether the metal mesh cover can enhance heat dissipation. After several days, I said that the mesh cover is suspected of opening the glue, and the gap will obviously feel larger.

The lens is usually protected by a lens cover. At the same time, the sliding lens cover also has the function of switching on and off. The small black spot next to it is the focus sensor.

Seen from the back, there is a huge radiator. At present, most intelligent projections are LED light sources, so heat dissipation is very important. In addition to the common USB, HDMI, network cable and headphone jack, the interface also has a DTMB digital TV interface, which allows you to watch digital TV without network, provided that you need to purchase an antenna separately.

The front is a 2.5D design similar to glass, the panel is plastic, and the visual effect is outstanding. However, the problem caused by this is that it is not resistant to friction. Even wiping with a flannelette cloth can leave scratches, and it is also a fingerprint staining device. I believe this is unexpected for the manufacturer. The middle part also supports touch operation, and the actual experience is not sensitive enough.

The heat dissipation window at the bottom has a filter screen with dense mesh and certain dust prevention capability.

The Bluetooth remote control supports voice search and manual focus adjustment. The middle key is the voice input key. I am used to the layout of Xiaomi, but I am not used to having the return key on one side. I have pressed it many times by mistake.

The power adapter is provided by Hangjia, and the quality is guaranteed.

There is no free stand at random. I bought the stand next to it myself. I suggest that I can put one in. Sometimes I go out to take photos and find the tripod too bulky, so I take a gadget out.

The middle is a standard screw hole, and the portable tripod can also be used.

Summary: The appearance design of Kuletv S3 is very fashionable, especially the 2.5D design of the top mirror. The metal mesh cover of the body is also unique. The disadvantage is that the top mirror is not wear-resistant, which will be terrible in actual use. The fixing method of the metal mesh cover is loose. I don't know whether it is an example. In addition, The receiving antenna of digital TV should be presented as a gift.

Part II: System

Customized Android system, the home page is divided into four major functions: film and television, music, office and application.

There are not many pre installed software, there is not too much clutter.

Built in office software, covering common file formats.

The film and television resources are basically similar to the TV box, but the advertising is annoying. The Galaxy broadcast control system knows all the resources, and fortunately, other APPs can be installed.

In the built-in software market, a lot of software does not exist, and it is much easier to use when reinstalling Dangbei.

set up:

It has the wall color correction function. Generally, at home, it is convenient to go directly to the wall. It seems that someone has heard that the cheap screen effect is no different from the wall.

It supports trapezoidal correction, but the actual feeling is not obvious, and sometimes it is still necessary to manually adjust the machine position.

Auto focus can be accurately recognized in most cases, and occasionally requires manual adjustment.

Manual focus demonstration

Summary: The built-in movie and television APP is rich in resources. There are basically popular movie and television resources, but the advertising is a bit long, so the usability is not very good. Fortunately, these can be solved through third-party APP. The functions of color adjustment, trapezoidal correction and auto focus are to some extent conducive to the experience of watching movies. The actual feeling is that except for auto focus, other invisible functions are not very obvious.

Part III: Usage

Through the gray scale test, there are many gray scale levels visible to the naked eye, and the picture availability is high. This gray scale test is only for reference, after all, it is not a TV set.

Picture display:

The projection ratio of Kuletv S3 is 1.2:1. A screen of about 60-70 inches can be projected at a distance of 2-3 meters. Although the maximum projection size is 300 inches, the resolution of the screen is 1280 * 800. It feels that the picture effect within 100 inches is good.

The actual picture display effect is also good, and the color is restored to reality.

Higher brightness plays a positive role in the picture effect, but the projection is not that the more brightness, the better. Too high brightness is also harmful to vision, and has a negative effect on the gain of the picture.

Video playback:

The resolution of Kuletv S3 1280 * 800 can only be said to be enough. If you don't look carefully, the graininess is not obvious, and the video playback is also smooth. If you have high requirements for image quality, it is recommended to choose 1080P projection. After all, it is the trend.

Are you also chasing Li Weiyang, a popular TV play nowadays?

The effect of video playback is also positive. Although 4K playback is supported, it is estimated that the reason for the bitstream is that my 4K movies cannot play normally.

game:

It's great to think about cutting fruit on the big screen.

Summary: As a wireless projection screen, the advantages of the large image of the projector appear. No matter playing games or watching videos, the visual experience is very good. The only slight regret is that the resolution of 1280 * 800 is lagging behind. Fortunately, the color performance is good. In addition, the sound performance of Huiwei Audio is good, and the overall quality is high.

Part IV: Performance Measurement

The brightness of Kuletv S3 is high, and the official declaration is 1100 ANSI lumens. Just because there is an illuminometer nearby, we simply measured it according to the nine grid.

First, the projection is one meter away from the screen. The screen is required to be 60 inches. It is not a professional laboratory, and it can not achieve Taijizhi. According to the actual measured value, the average illuminance range is about 900, which has certain reference significance.

The heat dissipation of the machine is simply measured with the help of a temperature sensor. The upper and lower temperatures are the machine temperature and the indoor temperature. After 2 hours of use, the temperature of the air outlet is 43.4 ℃. After observing for a while, the value changes little and remains relatively stable.

Noise experience, one meter away from the machine, simulates the human experience. The difference between the decibels before and after power on is 7.2 decibels. Generally speaking, 0-20 decibels is very quiet for ordinary people, and 20-40 decibels is quiet. Although the value is small, the noise perception is still obvious, which may also be related to the silence at night.

Summary: From the above experience, we can feel that the machine has a high brightness, good heat dissipation, and no obvious temperature change for a long time, but the huge heat sink must have a lot of dust in the later period. Cleaning is a problem. In addition, the noise of the cooling fan is still very loud at night. In this regard, the mute processing needs to be strengthened.

advantage:

1. The appearance design is fashionable, and the effect of Huiwei speakers is good

2. High brightness, small size projection, good picture quality.

3. Support DTMB digital TV

Insufficient:

1. The resolution is not high, the quality of large size projection picture is poor, and the digital TV antenna is not provided with a free gift.

2. The trapezoidal correction experience is not very obvious, and it is still necessary to manually adjust the stand in many cases

3. The design of the top cover mirror is a bit weak, which is not practical

4. Preinstalled software and resources are not very playable
