After the beginning of the year, Nut and Dangbei have released the latest projection products, Nut J10S and Dangbei F5. The scramble for the release of the two products made the projection market after the Spring Festival instantly heat up. Some users who are purchasing projection equipment believe that they will also be more interested in these two machines, after all, they are from well-known domestic brands, and these two products have also chosen the same chip MT9669 chip. This chip uses a quad-core Cotex A73 architecture, which is also the most commonly used domestic projection flagship. So in actual performance, which product is more worth recommending? Let's try to provide this answer to consumers through a series of comparisons and actual measurements.
First of all, the problem of chip tuning, users who pay attention to projection equipment believe that they all understand that sometimes different manufacturers use the same chip, but due to the difference in the tuning and adaptation of manufacturers, the final performance will also bring a big gap. Nuts have used MT9669 as early as two years ago, and perhaps nut J10S can bring better performance. Before the experience, the author had such an idea, but the comparison test is still to be realistic, let's use real pictures to make the two products compete.
I believe that through the comparison of real pictures, it is not difficult to find that the author's initial conjecture is correct. After all, Dangbei F5 is the first time to use the MT9669 chip, coupled with the model of Dangbei has been providing technology in the foundry, the lack of technical accumulation, it is naturally difficult to control this chip. In contrast, nut J10S, the previous technical accumulation has laid a good foundation for this product, in terms of color reproduction, especially portrait color restoration, nut J10S has shown a first-class level.
It is not an easy task to do a good job of color restoration. In order to better achieve such a goal, nut J10S is to avoid going further and further down the crooked road of hardware parameters, specially invited Leica to carry out in-depth cooperation, set up a technical expert group, together with optical technology communication and image quality tuning, and finally nut J10S achieved the D65 standard. This means that the Nut J10S has reached Leica's approval in optical standards, and with Leica's blessing, in terms of color, the Nut J10S is better than the Dangbei F5 without suspense. In terms of image performance, nuts have actually conquered many users with strength in past products, and this time under the technical blessing of Leica, it can be said to be the icing on the cake.
The above-mentioned portrait color restoration, in fact, in the industry has become an important indicator to judge whether the projection equipment is excellent, nut J10S in order to achieve a better effect, at any cost to polish the product, the color restoration function of deep tuning, and even through a large number of real skin tone performance, by comparing the skin tones of more than 300 people, to achieve the most real, the most natural color restoration.
In addition to the huge R&D resources invested in the nut J10S in restoring color, the investment in picture quality is far more than this. In order to achieve better results in image quality performance and fully reduce the sense of delay felt by users when using the device, nut J10S also added another killer at the chip level - iChips independent display chip, due to the addition of this independent image processing chip, the projector can achieve side projection 3D function, side projection low latency function, whether in the process of watching 3D movies or large-screen games, are more enjoyable, not limited to positive projection. And these functional experiences, relying only on the MT9669's Dangbei F5, obviously can't do it.
In addition to the experience of the above modules, the author also tested various functions, whether it is autofocus, trapezoid correction, automatic obstacle avoidance, automatic screen alignment, etc., these functions are equipped with two projectors, but the nut J10S's sensorless trapezoidal correction only takes 2 seconds to get the square picture, and the whole process did not interrupt the viewing. When the Bey F5 not only needs to project auxiliary graphics, but also takes a long answer of 10 seconds to complete the ladder. Therefore, in terms of basic functions, there are also some gaps between the two projectors. In the smart screen function, the two also have different schemes. When the projector detects that the projected screen is occluded by objects, the nut J10S adopts the method of breath screen, which directly cuts off the stimulation of the light source for children and animal eyes. Dangbei F5 uses to reduce the brightness of the light source to reduce the stimulation of the human eye. Such an experience is obviously that the nut J10S is better and pays more attention to the actual feelings of the user.
After a series of comparative trials, the author can responsibly say that the nut J10S is much better than the Dangbei F5 released at the same time, whether in terms of image quality performance, or use of functions, etc. If you are reading this article, you have recently purchased a plan to purchase projection equipment, I believe that nut J10S will be a good choice.
