On December 9, JMGO Nut Projection released the new flagship nut N1 Pro/N1 Ultra tricolor laser PTZ projection. The product definition is very special. The core selling points are three color laser, built-in PTZ, 110% BT.2020 color gamut (BT.2020), 3200/4000ANSI lumens, and 6499/8999 yuan.
We Love to play computer games As one of the world's top 500 evaluation studios, it is natural to sneak away to get the new machine, and then naturally drag the draft. Now let's see how the second tricolor laser home projection of Earthman can be made.
In addition to science popularization, the core of this experience is Brightness, color gamut, speckle elimination effect, Other brief omissions.
Specifications
Nut N1 Pro and N1 Ultra are 6499 yuan and 8999 yuan respectively. The difference of 2500 yuan, It is mainly due to the difference of shell material, resolution, laser quantity (brightness), and other image quality parts are the same : 0.47 inch DMD chip, 110% BT.2020 color gamut, 1600:1 contrast, Δ E<1 color accuracy.
Even MT9669, 4+64, 2x10W audio, HDMI 2.1 (one with eARC), and Wi Fi 6 are the same.
Laser Projection Science Popularization: "It may be frequently tested in the future"
At the beginning of this year Hisense Vidda C1 Is the most famous tricolor laser home projection. The selling point is the 7000 yuan three color laser, with 107% BT.2020 color gamut, which was blown out by everyone at that time. But the actual cost is 1350ANSI lumen brightness and relatively obvious speckle phenomenon. The nut N1 series of this experience is the second household projection with a three color laser.
Laser projection is the technology trend of high-end projection, which should be seen frequently in the future. Here is a simple science popularization written in advance for later copying.
Projection lights include:
Light bulb: Ultra high pressure mercury lamp is mainly used in old-fashioned and office projection. High brightness. But the color gamut is low, the life is relatively short, hot and fan sound
LED： Intelligent projection of mainstream light sources. Low cost and long service life. But the brightness is low. Generally, 2000ANSI lumens reach the top
Laser: It is mostly seen in tens of thousands and hundreds of thousands of flagship projection and laser TV. Tri color laser has the highest color gamut range in civilian display equipment, with long life and high brightness. But there are speckle problems, and expensive, expensive, expensive.
There are monochrome, bicolor and tricolor lasers, Monochromatic laser It is blue laser+color wheel phosphor, limited by principle, red display is a weakness. Tricolor laser The red, green and blue primary color laser is used directly, and the color gamut is exploded, but there is a speckle problem.
Speckle, The story starts with the Big Bang , making the picture like it is separated from frosted glass, with its own "noise", uncomfortable, dizzy, tired, and eye injury.
Nuts' improvement on the three color laser scheme is concentrated on this self-developed three color laser light machine called "MALC mesh krypton". Disassemble the manufacturer's promotional terms:
Leveling system: "400 partition four layer compound eye levelling system" refers to four patents, and the core is multi-layer processing to make the laser uniform from point to plane. Declare 95% uniformity.
Speckle elimination: The "LSR dynamic speckle reduction technology" includes three patents, the core of which is to upgrade from the single axis vibration speckle reduction scheme to the XY axis two-dimensional vibration, which can be used as a reverse OIS optical anti shake. It claims that the speckle elimination rate has increased from 90% of the mainstream to 96%, which is lower than the detection threshold of 5%.
Modular laser stack (For cost reduction): from the mainstream single chip to multi chip stacking, the laser components are unified. Different levels of product lines use different quantities of lasers to increase the purchase of components in a disguised way, reduce the cost of a single laser, and then stack multiple lasers to win the competition of a single laser. The "incidental" advantages include reduced volume, heat dissipation and efficiency improvement.
This is the most interesting place for me. Direct customization with source suppliers will reduce the price difference earned by middlemen, and the cost will be lower than that of peers who buy public laser. In addition, the public laser will have more design redundancy, which will also increase the cost.
The mainstream laser in the market is a single 14 core laser (such as Hisense Vidda C1). Nutamari Chemical customized a "9-in-1" chip (4R3G2B, 4 red, 3 green and 2 blue) laser (model NUMB12T). The N1 Pro uses two pieces (18 cores), and the N1 Ultra uses three pieces (27 cores, almost twice the common scheme). Because they are stacked by the same type of lasers, only the brightness is different between N1 series, and the color gamut and other parameters are highly consistent.
appearance
The nut N1 Ultra is packed in a portable foam box with a handle when it leaves the factory. There are power supply and remote control storage slots in it. Previously, this kind of package was only seen on UAVs.
It's hard not to associate it with camping when equipped with its own PTZ bracket.
Nuts are equipped with a 24V 7.5A 180W power adapter for nut N1 Ultra (N1 Pro is 150W), which is higher than many game books in power, 17.5x7x3.1cm, showing the "domineering".
Below are two rows of speaker openings (2x10W)
The shape of nut N1 Ultra is a bit like a rocket launcher/searchlight. The round style of the nut example. The black part is the spraying process, and the black part has the effect of glitter.
There are air inlets on both sides of the fuselage, and the air is discharged from the rear grille. The heat pipes inside can be seen faintly.
The front one is CNC stainless steel with high gloss coating, which is exclusive to the noble N1 Ultra with 8999 yuan.
With PTZ+true · instant correction
The nut N1 Ultra's double axis PTZ (the disc on the base can also rotate) makes it have Lie flat and free , the picture can be projected to the ceiling or both sides at any time. Only when the ceiling is cast, certain requirements are put forward for the financial resources of users (it is better to have a floor height of more than 3 meters).
If it needs to be mounted on the support or ceiling, the cover of the shaft can be opened, and then the shaft can be locked. The disc of the base can also be removed and connected to the 1/4 screw port to retain the rotation function. It is a good platform.
Inside the PTZ is a NBR "shaft" with 15-20N (1.5kg to 2kg) rotational damping, which can hover freely. The actual body feel is similar to turning the high-end display, but it is smoother.
With this PTZ, Nuts said that they had engaged in "6-axis gyroscope+ToF+TMR magnetic induction focusing". The official terms are false, and the curative effect is directly determined ↓
Notice that the ceiling/camera does not move, only the projection direction is moving (from the lower left corner to the right).
Nut N1 Ultra is the most powerful escalator calibration and focusing system at present , far away from the old record.
Not only is there no checkerboard in the correction process, but it is even adjusted during the movement. At the media conference, the machine with the new firmware can always follow the correction even when it is dumped randomly, which is too stupid.
However, I am not a bar, but I am a bit curious: since 70% of high-end users use fixed positions of supports or suspended ceilings, is this scheme more suitable for entry-level products? This is a bit like the "automatic obstacle avoidance dilemma" of UAVs. The more high-end machines avoid obstacles, the better. However, novices need to avoid obstacles most. They always use the entry-level model of obstacle avoidance.
Like Dajiang, nuts are the standard version after Pro/Ultra. There should be a place reserved for nut N1. Maybe it will be a scaled down version? Simple PTZ version? Or the entry model of optical and mechanical equipment with the top PTZ reserved?
Picture quality: 4000ANSI lumens+110% BT.2020 color gamut
Let's start with what we care about most Speckle problem.
At the time of unpacking test, we didn't even check the data, and we didn't know the speckle problem of the three color laser projection. As a result, Ben Liangzai and several computer obsessed Liangzai didn't notice the speckle (even the highest rating), and even didn't notice when they were close to taking pictures of details.
However, the individual differences of human beings are huge. Just like some users can see the rainbow pattern of intelligent projection like a camera, some users will be particularly sensitive to low-frequency PWM, and we cannot guarantee that everyone will not notice the speckle problem. If you are worried about this problem, you'd better see the real machine effect on the spot.
The claimed leading range of nuts is only for reference before the third-party objective data is available. Let's talk about experience.
The Leica logo is too small, I'm not very satisfied ↑
The projection ratio of nut N1 Ultra is 1.2:1. It takes 2.7 meters to shoot 100 inches and 120 inches to shoot 3.2 meters.
Emulsion paint white wall, 100 inches. The left is the black light scene, and the right is the simulation effect under the normal light of the office ↑
4000 ANSI lumen brightness of nut N1 Ultra, This level is equipped with a 100 inch hard curtain, which can be basically used without pulling curtains in the daytime. As a reference, the LED projection is generally 2000ASNI lumens at the top, and the 10000 yuan laser TV/short focus projection is 4000-5000ANSI lumens.
In addition, it is a "telephoto projection". Once the projection distance is less than 1 meter, the light designed for the 100 inch screen is concentrated to less than 38 inches, and then you can experience the visual experience of the artificial sun. Its brightness is so high that the system will enter the "strong light anti glare mode" by default when objects pass by, or even when the PTZ is rotated.
And the color gamut is what I am most interested in.
The common color gamut is as shown in the figure above. Mobile phones are now P3, and computers are still popular in sRGB. BT.2020 is much larger than them.
A few years ago, everyone thought the BT.2020 device was out of reach, but this year Hisense's three color laser is 107% BT.2020, and nut N1 series is 110% BT.2020 。
In the color style of nut N1 Ultra, there is a "Leica dazzle" mode with a pop color gamut, which is the highest color gamut available for consumer electronics.
However, the actual color gamut is too high, and the camera can't actually shoot it. Just listen and make up: the naked eye can clearly see the difference in color saturation of several modes, especially the red and green performance of "Leica dazzle". The leaves are green enough to drip out, and the red is bright enough to catch fire.
Leica standard and office mode of nut N1 series, official standard Δ E<1, but there is no condition and time test.
Because the "Leica dazzle" is too exaggerated, the "Leica bright" mode is uniformly used below, which is used at a distance of 2.7 meters. At this time, the projection picture is 100 inches.
Real shot:
Original picture/video ↑
As we all know, the camera cannot reproduce the projection effect seen by the naked eye. It is also the first time for us to take a remake of the projection of the three color laser. The camera's remake feature is that it looks normal to the naked eye, but the picture will turn red.
The most profound visual impression of nut N1 Ultra is brightness and contrast.
The 1600:1 contrast of the official standard exceeds that of the advanced mobile phone LCD (although, LCD will never be a slave!!!) 1500:1 of.
The contrast is not high, but the peak brightness is really too high. At 100 inches, the ordinary latex paint white wall is used. Under the weak indoor light, no matter what the nut N1 Ultra displays, it is as if the HDR effect is turned on, which is achieved by the violent brightness. When sunlight or neon lights appear on the film screen, you will unconsciously squint your eyes. It's too bright However, the brightness of the push blasting is too stimulating. It is recommended to pull it to 120 inches or directly turn on "Automatic brightness adaptation of ambient light".
In terms of brightness, light bulb machine can also do it, but nut N1 Ultra The black field pressure is also very low. With normal trapezoidal correction, you can see the black "border" that has been cut in the black light environment, but as long as it is not a pure black environment, the pure black part of nut N1 Ultra is really hard to see.

Thanks to the high brightness and 0.47 inch DMD chip, the detail performance is not far from the real 4K TV. Nuts N1 Ultra The 4K effect is obviously better than any 4K projection that we have seen before, and many entry-level laser TVs have been killed.
Sound effects and systems
Here are some mature parts or parts that I don't care about.
The room temperature is 23 ℃. After operating for 1 hour, the highest temperature of the fuselage is at the back, 36.3 ℃. The temperature control is OK.
Wind noise is no different from the common 5000 yuan projection.
Nuts, Jimi and Dangbei are intelligent projection factories, and their audio is more volume than that of intelligent speaker factories. It's hard for ordinary people to imagine how a projector of this size and 2x10W power can achieve such high volume and sound quality. Take it out to the square dance, and Aunt Wang of the next village will look up at you.
If you want to upgrade the original audio obviously, you have to spend all your money on multi-channel audio (the main investment is to buy a house).
New Bonfire OS system, in cooperation with Frog (the "frog" design company often used by Apple).
Compared with the previous LUNA OS, the logic of the whole system is different from that of traditional projection/smart TV.
The system settings are still disassembled into the global floating menu (see what are the adjustable items ↑)
The labels on the top are the indications of different spaces. In addition to watching movies/music (inside is the traditional system interface), there is also an atmosphere space to make the wall into a campfire/atmosphere wall (for party/dinner, there are more customized items than the lock screen interfaces of some domestic mobile phones). The rhythm space includes "wake up, help sleep, and focus" Several categories (in any case, users are encouraged to put projections in their bedrooms).
In order to get the dynamic effect inside, several desktop spaces are actually made with Unity game engine, and they are real-time rendering. The GPU performance of MT9669 will only be enough, so we know how high the rendering accuracy is.
As for the image quality items that we most care about, in addition to the granularity of saturation and contrast adjustment, Gamma、 Dynamic contrast, noise reduction and motion compensation are basically all adjusted in the third gear.
There is still an office mode connected to the computer, and a game mode with intelligent functions such as image noise reduction/motion compensation off (the minimum 10ms delay is claimed).
summary
The SoC of the N1 series is not fully loaded and the single USB interface is not available, but I have no personal opinion about this. Anyway, the target users may only use those two HDMI 2.1 interfaces.
If you want to be the top flagship, I hope you can improve the design and texture of the remote control. If we want to pursue cost performance, we should remove the most powerful escalator calibration/focusing system and PTZ, leaving only the core optical machines and systems, so as to create a true cost performance version for the ceiling for us poor people living in No. 1 Shenzhen Bay?
The actual performance of nut N1 Ultra, I would like to call it the top of domestic telephoto projection This is the highest evaluation we can make for a projection. But the price of 8999 yuan is really expensive. The price of the 6599 yuan N1 Pro is more sweet. Now the pressure is coming to Hisense (the high brightness 1080P and low brightness 4K are PK).
