Every time I see each projection manufacturer launch a new product, they all play a variety of selling points, but the projector is not like other digital products, due to the rapid rise in recent years, coupled with the continuous improvement of the technical level, the user audience compared to the large-scale popularity of television, can only be said to be gradually out of the circle. So how to judge the performance of a projector, from which angle to judge, this is a difficult problem for many consumers.
Take the recently released Dangbei F5 and Nut J10S, the main selling points are color, brightness, sound quality and other aspects. Today, let's take a look at whether these two projectors really have excellent picture quality from these 3 aspects.
When the price of the Bei F5 and the Nut J10S is similar, they are all MT9669 high-performance flagship chips created by MediaTek. The Nut J10S is a dual-chip projection with an additional i-Chips, which effectively improves the independent image processing capabilities and improves the projector's 3D side projection performance a lot.
In terms of picture color, Nut J10S has made sufficient efforts in restoring the original color of the image, combined with the well-known professional brand "Leica", which has more than 100 years of experience in the field of optics and image signal processing, and the two sides have deeply cooperated to form a technical expert group to carry out optical technology communication and image quality tuning, strictly adopt the D65 color standard, combined with 140 kinds of color cards to proofread color accuracy. In terms of portraits, 5 human skin tones and a total of 300 portrait samples were used to repeatedly proofread the skin tone texture, and finally ensure that the picture can display the most natural color state of the portrait skin color according to Leica professional standards.
You know, the working principle of the projector is diffuse reflection, which is different from traditional TV, so it has always been a difficult point to overcome in terms of color reproduction. In the home projection of the LED light source, there will be three-color LED light beads to provide three primary colors of light, and the corresponding color of the picture is realized by quickly illuminating them separately. In order to control the price cost, increase the brightness in the corresponding price range of the product, under the premise of not replacing the LED light group configuration, you can only start from increasing the proportion of blue-green light, which will increase the brightness of the stream a lot, but it does cause many users on the market to feedback the projector screen is green or blue.
Take Dangbei, for example, Dangbei F5 is also OK in color, but it has the common problems of other projectors: the picture has color difference, the color color of the portrait skin is white and blue, the contrast is weak, and there is no blood. In contrast, although the nut J10S is slightly lower than the Dangbei F5 in terms of brightness parameters, when it is actually used, the image quality color reproduction advantage is too obvious, but it looks brighter and more vivid visually.
In addition to the color and brightness of the picture, the difference between the two is also relatively large from the perspective of intelligent experience. Since it is a smart function, it must be able to intelligent feedback, convenient and fast, with these, it can be said that it is a qualified "flagship" projection. According to the comparison of the automatic obstacle avoidance of the two projectors, in this regard, the Nut J10 is obviously better than the Dangbei F5, which is because the Nut J10S is equipped with AI-VISION intelligent space perception technology, and the functions of automatic keystone correction, automatic obstacle avoidance, and automatic screen alignment have been upgraded to version 2.0.
Here to say about the automatic trapezoidal correction, upgrade to 2.0 is the senseless trapezoidal correction, you can easily complete the non-inductive adjustment within 2 seconds, there is no auxiliary image, the picture changes softly and smoothly, for the user is completely without visual disturbance. Looking at the dangbei F5, it takes more than 10 seconds to complete the entire trapezoid correction process through the auxiliary graphics of the black and white grid, which is really bulky.
The above is Xiaobian today compared to Dangbei F5 and Nut J10S experience sharing, through the comparison of these two products, Xiaobian saw continuous innovation, technology support, version upgrades and strong combination in Nut J10S, worthy of the nut's main flagship model in 2022. If you have recently purchased a projector intention, Xiaobian recommends that you can consider these two projectors, and if you choose between the two, Xiaobian recommends nut J10S.
