With the rapid development of the social economy, 60-70-inch large-screen LCD TVs have almost become the standard for every household. However, many users are still not satisfied. We hope that the screen can be bigger, but the LCD TVs are limited. As for the cost of materials, large-screen products with a size of more than 100 价格 are very expensive, and the price of tens of thousands of tens of thousands of people prohibits most users. So is there a big screen product that is more suitable for home users? Of course, the nut S1 we are going to evaluate today is an ultra-short-focus laser television that can project a 100-inch screen at around 30 centimeters. The most important thing is that the price of nuts 10,000 yuan more than 20,000 yuan compared to more than 100,000 LCD TVs to be much cheaper, for the average home user is very suitable, the following you please come and see me.
25999 yuan a hundred screen large screen nuts S1 laser TV evaluation
Nut S1 laser TV built-in 0.65-inch DMD chip, the standard resolution of 1920 × 1080, nominal 3000 lumens brightness, contrast ratio up to 20000:1, the projection of the picture is sharp and sharp, strong color contrast. As an ultra-short-focus product, the projection ratio of the nuts S1 is 0.25:1, and a large screen of 100 inches can be projected at a distance of about 30 centimeters, even if it is used by small-sized users.
Compared with traditional ultra-high voltage ** lamps, theoretically, laser light sources have advantages in terms of color and lifetime. The lamp life of a typical projector is about several thousand hours, and laser light sources can basically reach a service life of 10,000 or even tens of thousands of hours. Generally, the projector uses a light bulb to emit light. After a period of time, the color of the projector will darken and fade, and the user experience of the video image will be used. However, the laser generator has stable performance, and the long-term use will not cause such problems.
The above picture is the objective test result of the Nut S1 laser television. If your time is limited, you can use it to quickly understand the product. However, after all, the objective data is limited. The author still recommends that you look at the complete evaluation and understand the product completely before reaching a conclusion. Here we enter the evaluation of the nuts S1 laser TV.
The appearance of the whole machine is novel and unique
Nut products have always been distinctive in appearance, this time the nuts S1 is no exception. According to the official news, the nuts of the S series adopt the "Pisces" shape of the Chinese traditional culture, while the curved design of the Nut S1 laser television plus the vibrant gray color can be said to be the Chinese traditional culture and modern. The perfect combination of technology.

The nut S1 laser TV interface is designed in one row at the back of the fuselage, with reasonable spacing between holes to facilitate simultaneous connection of multiple devices. With symmetric stereo speakers on both sides of the fuselage, the sound effects are flawless and the sound field is wide, giving you theater-like surround sound enjoyment. There is no operation interface on the body, users can only operate through the remote control, slightly inconvenient, of course, this may be considered for the overall aesthetics.

According to our actual measurement, the power of the Nut S1 laser TV is 164.6W. As a home-used electrical equipment, it can be completely accepted by consumers. In addition, compared with other similar products, the power consumption value of the machine is relatively low. It can be said that Nut S1 is a very environmentally friendly product. In addition, the noise of the nut S1 during operation is 56.6 dB, and the overall operation of the machine is relatively quiet, which will not affect your viewing.
Brightness and contrast performance
Projector Data Testing We mainly use the ANSI standard developed by the American National Standards Association. This standard is also recognized as an authoritative standard in the industry. And consider the following aspects: maximum brightness, peak brightness, optimized brightness, and projector contrast color. Next, I will briefly explain a few technical terms for everyone: The first is the peak brightness, especially in the brightest mode, the highest brightness can be achieved at a single point, generally appear in the center point; maximum brightness, refers to the brightest mode The average brightness that can be achieved on the screen is higher than the reference value of this value; the optimized brightness, also known as ANSI brightness, is the average brightness of the 9 test points in the case where the projector can just distinguish eight gray scales.
Eight gray levels and 13 illumination test points
Two different contrast test methods
data analysis:
Regarding the brightness of the projector, there are two data in the table, namely the peak brightness and the ANSI brightness. In simple terms, the maximum brightness is the average brightness of the screen in the brightest mode of the projector (brightness, contrast, and lamp mode are all adjusted to the maximum). Since the nut S1 we tested had only 10 brightness adjustments, we chose the fifth gear to test ANSI brightness and select the 10th gear to test the peak brightness. From the results of our actual tests, the ANSI brightness of the nuts S1 is 1825 lumens, which is sufficient for the daily use of the average home user.
Peak brightness refers to the maximum value that can be reached at a certain point on the screen in the brightest mode. In general, peak brightness is best if it can approach 95% of the nominal value or even exceeds the nominal value. From the actual test data, the peak brightness of the nuts S1 is 2105 lumens, only reached the nominal 70.16%, showing a slight lack of performance.
Contrast:
In the contrast test, we brought you two data, one is ANSI contrast and the other is FOFO contrast. The ANSI contrast is closer to our daily viewing experience. We used 16 black and white color patches for testing. In the daily video, if there are some very bright or dark pictures, the FOFO contrast level will affect the viewing experience, and the value will be tested by the picture is completely white and the picture is completely black.
From our measured data, Nut S1 has an ANSI contrast ratio of 109:1 and will meet good standards. The FOFO contrast ratio is 1423:1. It can be said that in terms of contrast, the nut S1 is not good enough.
The degree of color reproduction is generally dark
The quality of a projection product is a very important evaluation indicator. In this project, we mainly understand the color reproduction ability of the machine through the difference between the color test sample and the real shot image. In the previous contrast test, the nut S1 was slightly pale, so what exactly did it do in practice? Let's take a look at it.

Through the above group of real shots we can see that the color reproduction degree of nuts S1 is normal, the color performance is slightly biased, and the overall picture is dark. However, the overall color level is still relatively clear, and the focus is relatively clear. For the average family user's daily viewing, this performance is fairly acceptable.

From the above four-color chart comparison, we can see that the color of the picture projected by the nuts S1 is still relatively positive and there is no serious color drift. However, the overall picture is still dark and the projected images are not so beautiful.
Built-in resource-rich operating experience, outstanding nut S1 laser TV equipped with intelligent systems, interface design clean and simple, easy to get started without spending too much time to learn. In addition, the machine's memory reaches 2G, ensuring that the general daily viewing is fast and smooth, and there will be no Caton phenomenon. Nuts S1 is rich in resources, not only has a large variety of large movies, the built-in games are also very diverse.

Not only that, Nut S1 laser TV can also read the local content, insert U disk can read local files, pictures, and play video, use very convenient. Also during operation, the background music played by the nuts S1 is soothing and gentle, giving the user a very relaxed feeling.
Abundant resources, unique shapes, young people, good selection
Nut S1 laser television is novel in appearance, very decent on the indoor environment, the interface design behind the fuselage is rich, reasonable spacing between holes, convenient to connect multiple devices at the same time, but because there is no interface in the body, daily use requires remote control carry out. It is worth mentioning that although the remote control of this machine has a good feel, it is heavy and it is a bit heavy to use. In addition, the whole machine's running energy consumption and noise decibels are relatively low, and it is very environmentally friendly.
We have reviewed many projection products before, although the nominal brightness is higher, but the measured ANSI brightness is mostly only about 2000 lumens, so the nuts and lanterns S1 laser TV 1825 lumens of ANSI brightness can fully meet the viewing needs of home users. In addition, the expansion content of the machine is very rich, and a large number of 3D blockbusters and game resources are built in to make your leisure life more colorful.
Nut S1 laser TV color reproduction is generally, the overall picture is slightly darker. However, with the 1080p resolution of the machine coupled with a powerful built-in system, the Nut S1 is a very good product. The most important thing is that compared to other laser TVs, the price of more than 20,000 yuan for nuts S1 is still very attractive for home users.
