Nuts, one of the three domestic intelligent projection giants, released a high-end J series new machine - Nuts J10S at the end of February. The core selling point is simple and direct, which is the color performance brought by Leica's joint research and development. In addition, there are five functional highlights: 2400 ANSI lumen brightness, Wi Fi 6 and HDMI 2.1 support, and Dynaudio speakers. The initial price is 5599 yuan.

Projection effect: Dewei!
Projector, what else can I say? Look at the picture directly!
The Leica flavor of nut J10S starts from the boot boot interface. The system will ask the user which Leica mode to select when the system is powered on for the first time ↑
The left is the original picture, and the right is the live shot ↑
Needless to say, the problem of picture clarity and focal plane is to do a good job. This is the high-end projection basic line of 5000 yuan 0.47 inch DMD.
On the global MEMC side, MT9669 itself supports 120Hz MEMC motion compensation, but nut J10S also adds an i-chips independent display chip (Fage said it is very shameless), which is more natural than the image of projection motion compensation, without any sense of discord, and many times they simply do not notice that they open a complementary frame.
Nut J10S is a medium short focus projection with a projection ratio of 1.2:1. It takes 2.66 meters to cast a 100 inch picture. What is the effect of 2400 ANSI lumen brightness?
When the nut J10S projects a 100 inch picture, the light can also be turned on to maintain a certain visibility. With the anti light curtain, the living room is actually OK in the daytime, which does not mean that it cannot be used. But the core is still the impact on the picture effect: Nut J10S has automatic brightness adjustment, which can press the brightness to the appropriate range in the darkroom, so that the "excess" brightness can be left to HDR, and there is more room to pull up in the face of highlights.
When watching the test film of "Kyoto Red Leaves", when the sun passes through the gaps between the bamboo bushes, it is really as dazzling as the real sun. Oh, my God, this is the first time to watch HDR video with the 12.9-inch iPad Pro 2021 2TB cellular network, the first full version of the non Hainan duty-free version of the Bank of China. Translate it, this is the brightness level that can not be reached by non high-end projection now, and the level that can not be reached by 2000 DLP projection in 3 or 4 years (I hope that technical progress can make me hit the face).
As for the influence of DLP projection's color wheel, even if the camera's color temperature, shutter, aperture and other parameters are fixed, it is difficult to get the actual effect. It needs to be compared with several test charts for reference. Nut J10S Comparison of four modes of live shooting:

The nut J10S generation is dominated by Leica color (all stand up! The domestic intelligent projection has finally begun to make color accurate!). It is claimed that Leica's joint training, color, grayscale gamma, noise reduction and sharpening algorithms, all of which use Leica's schemes and standards, have optimized 300 skin color images of five people. Good guy, China is the only one.
More importantly, the nut claims that it has been calibrated before leaving the factory, and the accuracy has been adjusted with a 140 color color card (the normal color calibration test is only 104 colors. However, the color calibrator we usually use to test mobile phones is not suitable for measuring projection, and cannot be verified temporarily).
Nut J10S provides four screen modes by default:
The top must be Leica D65 standard mode The standard 6500K color temperature is adopted, and the pursuit is color restoration. The difference is obvious only when compared with other modes. AI sharpening and noise reduction processing did not produce a solid color "contour", and the effect was in place. The visual perception of the picture is really "German flavor", and the evaluation directly applied to Leica cameras is totally correct: rich and airy colors, sharp and giving consideration to dark details, rich red and blue performance, natural color transition and skin color performance. If the algorithm can add a touch of dark corners to make up for the thickness of the film, it will be perfect;
Leica Vivid Mode , similar to the same name mode of Huawei mobile phones, the color temperature is significantly cooler by two levels, and if you continue to increase the contrast and saturation, the image brightness will also be higher by one level, a typical flattering type. But just like the Leica bright mode of mobile phones, this mode is prone to oversaturation overflow of red and blue, resulting in 120% of the sRGB color gamut coverage of the phone body rushing out. It doesn't matter much if you watch cartoons and balls, but it is more recommended to go to Leica D65 mode if you watch movies;
Office mode , the original picture without any sharpening and noise reduction effect, the picture details can not be compared with other modes, but it is suitable for computer connection and text scenes;
User mode, In fact, it is a user-defined mode, with six adjustment items of "brightness, contrast, color temperature, hue, saturation and sharpness". But when sharpness has 20 gears and others have 50 gears, why is there only 3 gears for color temperature? The brightness adjustment gear is not enough. These two items have a great impact on the later color calibration. I hope that the OTA can be upgraded later.
Appearance design
The accessories are hand-painted design drawings by Zhang Xinyi. Nuts are equipped with a game book level 200W power adapter for the 160W nut J10S, with sufficient power margin. But reasonable, this is also too strong unreasonable bar.
The pure white Bluetooth remote control is decorated with silver circle direction keys, and the bright noodles on the back are used as embellishments. The side focus button is turned on, and there are two more shortcut buttons related to setting than the common remote control. The counterweight should be placed at the bottom of the battery compartment, and the center of gravity should be firmly in the palm of your hand, so that other manufacturers can learn from it.
Even as the owner of Shenzhen Bay No.1, who is well informed and has numerous readers, I was still surprised. Excuse me？ Are the projectors covered with 3D polished AG glass? There is also a coating underneath, which can reflect high light into light columns. This top cover always makes people unable to help themselves.
Familiar body layout: huge speaker grid on both sides, all interfaces are concentrated on the back, the front two feet can be raised about 1cm, and the lens is directly covered by a whole piece of glass. The core "decoration" is the Leica lens logo beside the lens and the Dana faith logo on both sides. The top cover penetrates four microphones with a polished ring left by etching, and the inside is a ring shaped power indicator, corresponding to your own LUNA OS (as the name implies, "Moon System").
The appearance design of "frigid" minimalism+low-key industry+mellow home, in addition to universal home adaptability, the biggest advantage is easy care. The lens of Jingui is sealed well, and the gray body does not appear dirty for long, I like it。
System, sound effect and heat dissipation
In the system part, this LUNA OS based on Android 9.0 has the greatest advantage of UI aesthetics. There are floating settings pages, round corners and rectangles everywhere, and the layout of elements is unified and comfortable.
For one thing, Dana's tuning edge was covered by Leica's Coke label. The double 8W speakers of Nut J10S are of high quality. What impresses people most is its huge volume: 30% of the volume is home audio, 50% is cinema, and 100% of the volume can make you stand out in the square. If you add a subwoofer, you will be the eternal god in the square.
The room temperature is 22 ° C, the volume is 50%, the motion compensation is the highest grade, and the noise is moderately reduced. After the 4K repair version of Cat and Mouse with a 1-hour aftertaste of nut J10S, the heat is concentrated in the heat dissipation grille area at the rear of the fuselage, and the maximum temperature is 42.2 ° C. The heat dissipation grille of nut J10S is really big. The heat pipe inside can be seen a few meters away. The air volume is large but the wind noise is small. It is quite quiet in daily life.
Wi Fi 6 and HDMI 2.1: Stand up again
It has been three years since we finally used Wi Fi 6 and HDMI 2.1:3 for smart projection. Do you know how we have come through these three years?
Nut J10S is the first HDMI 2.1 intelligent projection certified by the Association (MT9669 is HDMI 2.1a, 48Gbps at the highest), which can support the 4K 120Hz 4:4:4 HDR10+output of next-generation game consoles. If you happen to have strong financial resources, Nut J10S also has two HDMI 2.1.
Although 1080P devices can't use such high specifications, HDMI 2.1 has a lot of game features, such as VRR variable refresh rate, QFT fast frame transmission, ALLM automatic low delay mode, fast media switching, and so on. Connecting to HDMI 2.1 will bring about a 20% improvement in psychological performance, and connecting the PS5 and XSX to devices other than HDMI 2.1 will cause pain.
and The initial launch of Wi Fi 6 is estimated to be more significant for ordinary users . Because many users are now looking for movie sources on their mobile phones, and then directly cast the screen. Some users even have a demand for cloud games. Wi Fi 6 is really in demand.
Oh, by the way, nut J10S not only has automatic obstacle avoidance (it can automatically adjust the image size when there is an object blocking the projection area), but also has eye protection functions similar to laser TV (someone in front of the lens will automatically stop the screen to prevent blindness. The measured trigger distance is about 1 meter), and also the first "insensitive trapezoidal correction":
After all, there are still a few users who want to hang the ceiling or mount the support for projection, and most of them are "free to put it". In the past, when I bumped into the table or moved the projector inadvertently, even if there was automatic calibration, I always played the auxiliary calibration map. Some models even did focus together, which immediately delayed 6 or 7 seconds. As the name implies, nut J10S, a "non inductive trapezoidal correction", does not need to print an auxiliary correction chart for trapezoidal correction, and will not interrupt the operation. It is also recommended that friends and businesses do something about it.
summary
The Leica color of nut J10S was quite unexpected, and the intelligent projection finally began to pursue color accuracy. With 2400 ASNI lumens and horrible sound volume, it really has a good viewing effect. Users who do not have very high requirements for color accuracy or do not know how to calibrate colors can save the trouble of buying/renting color calibrators. But its color temperature options are too few, not friendly to color calibration, the price is a little high, but it doesn't matter! We 10 billion subsidies (However, there is no food) You can watch the shopping festival and look forward to its performance.
The discussion atmosphere of mutual attacks in the smart projection market is really not good. The "shareholder war" is often staged, which is a disaster area for quarrels, a bit like the early domestic Internet. The most unexpected thing is that there used to be virtual labels for brightness data, and now there are still secretly changed brightness labels (no name will be called), good guy.
As users, we should look at products rationally. They must all have their own advantages and disadvantages. This should not be a competition between competing forces, just like nut J10S Leica's color is good, Jimi H3S's color is colorful and pleasing, Dangbei F5/X3's brightness is high, Epson and other 3LCDs The sharpness and saturation of the products are very good, but unfortunately, each product has its own choice. It is good to choose according to your own preferences. There is no need to be a spiritual shareholder, no need to be a "diode", and no need to circle the food (old Chinese customer).
You can learn about the current mobile phone circle (imaginary mobile phone circle): Xiaomi's mobile phone is cost-effective, and Mijia's ecology is easy to use. Buy Xiaomi. Huawei mobile phones have high stability. Buy Huawei. IOS is very comfortable to use. Buy an Apple. Other mobile phones have their own advantages. It seems that they are all good. Never compete with the navy and sunspot, nor do oral gymnastics with cloud players, keyman, and sprayer, nor do you want to convince them.
TV, projection, left hand Happy Water, right hand popcorn, potato chips, fried chicken, spicy chips, shrimp slices, Wangwang Xianbei, Baiweizi, melon seeds, cashews, pistachios, Snickers, Dove, Mahua, cookies, pork jerky, choose a quiet evening, turn off the lights, find a good movie, and spend a good night with you. Harmful, life is short, go well and enjoy it.
