Does it have HDCP 2.2 on the HDMI inputs? I am finding that many of these small projectors do not.

As with the lumens and contrast, you really can't trust anything that comes out of these companies as a lot of it ends up to be made up specs.

Yes, the U1 supports HDCP 2.2 as do the current production JmGO SA and the upcoming JmGO N21.

We've seen the ads already , but is there a local review out for the U1? In Chinese is okay.

No. The U1 official launch is Thursday in Beijing. I was just responding to the "no 3D" comment.

Is the U1 available in Hong Kong starting today? If so, then where?

If the U1 supports 3D and used the .66 larger TI chip, then the 3D image will be smaller than the full 16:9 screen. The micro-mirror array of that chip is 2716 x 1528, NOT 1920x1080. They would need to stop the XPR function that vibrates the chip for 4K and use a portion of the 2716x1528 pixels. I suppose they could upscale the 1920x1080 3D image to 2716x1528, but no one has done that so far. If they do it, and it works out, perhaps others would follow, and you would get a slightly sharper image. I'm skeptical, though. I think they are using the .47 1920x1080 4K chip used in the newer, smaller 4K projectors. That's all I'm saying. And using the small .47 chip makes more sense for the smaller size of the U1. I'm not trying to take away from the excitement of this projector, as it has a lot of wanted features. In fact, @JmGOUS , provide me a demo to put through it's paces, and I will give you an honest, unbiased review...

Here are some points to consider:
On this page it says the U1 uses the .66 chip and two phase 4K http://en.jmgo.com/news/native-4k-vs...-projector.htm
If you scroll down this page, you will see an image stating a .47 DMD is used. https://detail.tmall.com/item.htm?id...=3900573914354
The downside of the using the .47 chip is that light border around the image due to unused pixels in the .47 chip that all of the 4K projectors using that chip suffer from.
In another statement, it stated 10,000:1 contrast ratio. In the above link specs it states Contrast degree: 3001:1-4000:1
In the "revews" which appear to be rehashing the specs, it states the max lumens is 4,000. The specs say 2,000.

Remember my previous statement that you can't always believe the statements made by the companies that make them. The true nature of the projector will come out soon...will be interesting to see the truth...

Or, to give manufacturers the benefit of the doubt, it could just be typographical errors on promotional materials.

If this projector uses a .66" XPR DMD and features 3D it will be the first of it's kind. The .66" DMD has a 'native' resolution of 2716 x 1529 when the optical actuator is disabled. To display a 3D HD blu-ray you would either need to suffer with a large black border around the image or upscale the 1080p image to '1529p'. That's not cheap or easy. When considering the shrinking (shrunk?) market for 3D content, most manufacturers don't consider it worth the effort.


Meanwhile, a projector that uses the .47" XPR DMD simply needs to disable the optical actuator as the native resolution of the DMD is 1920 x 1080. That's native HD and makes running HD 3D cheap AND easy-- Or at least we hoped it would be easy. Turns out there are still some issues when passing a 3D source through an HDCP 2.2 HDMI connection. This is probably why a lot of .47" equipped projectors have simply chosen to omit 3D altogether.

What to do if you find yourself stuck with no hope of rescue:
Consider yourself lucky that life has been good to you so far. Alternatively, if life hasn't been good to you so far, which given your present circumstances seems to be more likely, consider yourself lucky that it won't be troubling you much longer...

Probably the wrong place to ask this but it's the only active jmgo thread I could find.

My fiancee bought me a j7. I love the hell out of it but I don't know how to activate a hidden menu for enhanced mode or whatever. My roku says it should easily do HDR 4k at 60 but always black screens if it isn't 30hz. Any thoughts? Thanks in advance!

Finally some pictures!

















Feedback translated from Chinese:

Quote:
The nut U1 lens uses 9 high-precision lenses, which contain UD lenses equivalent to the optical properties of fluorite lenses, which can improve the secondary spectrum elimination effect, with low refraction and low dispersion. As for the resolution of the projected picture, I have said before, it is 4K, and the brightness of the projected stream is 2000 ANSI lumens. If you don't understand the meaning of the ANSI lumen unit, you can check it online because some brands like to use IOS. Lumens are used as projection brightness parameters.

Each side of the nut U1 is provided with a metal mesh of "aviation aluminum alloy", and the sound is also designed behind the metal mesh. In terms of sound design, the nut U1 adopts a floating design sound chamber, a 53mm large speaker, 14 ohm low impedance, and is also equipped with a professional-grade DSP digital power amplifier chip.

The nut U1 supports the playback of 3D movies, and can be viewed with special 3D glasses. It also supports the opening of dynamic contrast and motion compensation.

The nut U1 is an ultra-short-focus laser TV with a throw ratio of 0.21:1. When you are 21CM away from the wall, you can project a screen of about 100 inches! The biggest picture that the nut U1 can project is of course more than 100 inches, provided that the wall of your home is large enough.

Hi there,

Do you have specs of the U1? Want to know if native resolution is in fact 4k.

No it’s pixel shifted. You aren’t going to see native 4k at this price for years.

[QUOTE=JRock3x8;56709818]No it’s pixel shifted. You aren’t going to see native 4k at this price for years.


Hi i understand its pixelshifted, but i just found the resolution will be 3840x2160dpi which is what I was asking. Sometimes, the chinese say 4k resolution but the projector is actually native full hd 1080p and only 4k compatible.

This one will actually show 8 million+ pixels, so its native resolution is 4k even though its pixelshifted. Great price, even for pixelshifting.

Anyone know if this can be shipped to australia? I know its chinese version only, but maybe we can still get it shipped. Tmall shows a listing with shipping to Australia, but im not sure if its legit. Anyone had experience shipping from Tmall or Taobao?

Yeah, good luck with that. And yes, it's proper 4K PJ that uses pixel shifting to achieve the resolution.

I thought someone said there was going to be an international model if you read back a page or so.

also CEDIA is next week so hang tight for at least a week.

Hi - It's great to see official represenation from JMGO on this forum! I have a few questions.

1. Does it mean all faux-4K projects from JMGO supports HDCP 2.2? Including the upcoming X3?
2. Besides the U1, will the X3 also have an international version? Where will they be sold? Any insights on what other models will have international version?
3. Do the Chinese version of the JMGO projectors have the ability to handle international power requirements (voltage and frequency)?

Yes.

Yes.

Where will they be sold?

JmGOUS in the US as well as internationally.

Any insights on what other models will have an international version?

Yes. More new models are coming later this year that will be both Chinese and International. It's too early to discuss them at this point.

3. Do the Chinese version of the JMGO projectors have the ability to handle international power requirements (voltage and frequency)?

The Chinese projectors are compatible with 100-240V however some models will not be officially sold outside of China.

Thanks for the quick response.
For consumers outside of US (such as myself, a Canadian), is the official international store the one on aliexpress (https://jmgo.aliexpress.com/store/)?
Are there plans on getting international versions certified for Android TV OS and Netflix?
Can you elaborate on the differences between the Chinese and international versions? Are there ways to flash the international ROM to the Chinese version?

JmGOUS is the official store for the US and Canada. We ship globally.

Netflix is self certification. I will pursue getting listed with JmGO Corp. Netflix and android TV both work with all JmGO International projectors.

They vary between models. In all cases the Chinese versions are Chinese only and cannot be modified for International languages. Some are the same spec wise and others are different. For example the SA is the international version of the SC. It has more ANSI lumens.

>Yes.


Appreciate your clarification on the above - do you mean both Chinese domestic version and International version of all faux-4K projects from JMGO supports HDCP 2.2?

I have owned a JMGO SC (purchased from Taobao) few months ago, but have not checked if it is HDCP2.2 compliant. I am very interested in the new U1 (Chinese version) but only if it is HDCP2.2 compliant.

Many thanks for your help in advance. Cheers

Hi schumy, does taobao and tmall ship these projectors to you outside of China? I go to the taobao and tmall links and they show shipping to me in Australia, but im not sure if the products are legit. How do i know who's selling it? Do you have a recommended store which you know shipped your SC and is now selling the U1. I dont care if its chinese language, ill figure it out. Just need to find the 1 icon for hdmi, the rest should be easy.

Thanks

Michael

We do not have information on the U1 in terms of ceiling mount. It will not be sold outside of China.

The S3 International 4K version cannot be ceiling mounted as we are told however this needs to be confirmed. The S3 will be released for sales soon.

That seems like an extremely odd omission. Why would anyone want to have this near floor level, or on a bench/stand when it could be mounted at the top edge of the screen and out of the way.
