Someone asked if this projector has "native" 4K and the response from Jeff Wong (the campaigner) was:

Resolution is 4K UHD 3840*2160 @ 60FPS by adopting pixel shifting technology

That is also on their product page: "Advanced pixel shifting technology, provide affordable and smart 4k uhd solution".

Ha, you are right, I read it wrong. That said 1,500 lumens would require 45 watts of LED power, plus 12 watts for sound. Again, batteries to handle that are questionable for more than an hour.

Something fishy about this. Why not have the lights out and show the sharpness and 4K quality of the image? By showing it this way, the image can be awful or not 4K and you wouldn't know. They might have this set up with the older TI 1080p chip that everyone is using for small projectors like this to demonstrate that it works, with the hope of installing the new TI 4K chip that has been announced for pico projectors.

Damn you TI, work on perfecting the larger 4k chips for home theater projectors.

The video shows at least they have something working.
Even if it were in the dark you would still not be able to judge if it's 4K while watching it on a normal HD laptop screen...
I hope it's real, if so the $500 is a really good deal. Even for HD it would not be a bad deal.
Well I'll wait a bit more and see if more definite information becomes available.

Chip and battery

When I asked about the chip used I received this response:

Yes, we adopted TI chip but it supports 4k UHD. The battery capacity is 36,000mAh

And later they clarified it's a 13.5V battery so according to my calculation that would be about 480Wh. That sounds like quite a bit. Maybe enough for the max 8hours playtime they advertise. It would be like 40+ hours of audio. No idea how much is needed for 1500lumen.

So we can use it to jump start a car too!
Did they name the model chip, or just "TI chip"?

Here are specs of the 4K TI chip, right off of Optoma's website. So the chip is real. Whether it is implemented correctly, who knows.

Quote TI: "Building on the introduction of the DLP660TE last year, DLP Products is taking it a step further with the introduction of the DLP470TE and DLP470TP chipsets. The DLP470TP is the most compact 4K UHD solution from DLP Products, and is optimized for size and power. This chipset is the best fit for applications that demand portability, and brightness levels below 1,500 lumens."

The fact that they won't show a good shot of the screen image without some detraction is concerning.

Those 2 chips are not available yet, so they could not show one working anyway.

TI probably has some initial product available as engineering samples, but I suspect you're right, they don't have a working sample yet.

Not even engineering samples available yet, according to TI's website, the Heimkino team is not really enthusiastic about the idea,

My first hope is the chip will actually deliver (near-)4k quality, like the heimkino guy says:
Quote: "where are they finding the "free spaces" to shift a pixel 4 times - up down left right -, pretty sure this will be a step back in quality vs the earlier 4k dlp-eshift one".//

Questioned them on their Indiegogo page about the chip they plan to use, never answered, and I just found I only see the questions I asked when logged in there, all my previous questions and answers were removed too!

Interesting, but JMGO has a projector with the exact same form factor that's driven by DLP tech, albeit 720p. Guessing just upgrade the internals and the DLP chip for the N-Tech version and voila, 4K.

Thoughts?

Could be, most Chinese manufacturers share their tech to each other then just stamp a new name and logo, wala, a new product, it boils down on how competent the company is and what their quality & costumer service would be like.

Hopefully this pj would come into fruition & live up to what it claims. Anyone has direct contact with those n-tech guys from Hong Kong?

I recently contacted the guy leading the campaign on Indiegogo to ask him some video samples where we can actually see the projector working in normal conditions...he never answered. With the funding they have now, they should be able to build something decent but I still have doubts. I bought the XGIMI H1 in 2016 on Indiegogo and I'm very happy with it but at the time of their campaign, they were able to demonstrate their product in normal conditions, N-Tech is definitely less outspoken about it.

The chip they are probably going to use, the DLP470TP, or the DLP470TE if they really go >1500lmn, is not even out yet so they can't show it.

AFAIK those chip could be released 2nd qtr?
they could use the 470TE as many are pushing for 2500 lumens

Quote:
•The DLP470TP is the most compact 4K UHD solution from DLP Products, and is optimized for size and power. Measuring 17 mm by 24.5 mm and supporting brightness levels up to 1,500 lumens, the DLP470TP can deliver 4K UHD quality to equipment such as mobile smart TVs and pico projectors.

•The DLP470TE is optimized for projectors needing over 1,500 lumens. This chipset is in a larger package, 22 mm by 32 mm, which enables it to withstand the heat generated by brightness levels up to 4,000 lumens.

•The DLP660TE is the most powerful of the three 4K UHD chipsets. This digital micromirror device (DMD) is designed to enable projection applications up to 5,000 lumens.

Availability
Developers can get started immediately with the DLP660TE which is available now in the TI store and through authorized distributors. The DLP470TE and DLP470TP will be in production in early 2018.

This chipset is the best fit for applications that demand portability, and brightness levels below 1,500 lumens. The DLP470TE shares many technical characteristics with the DLP470TP, but is optimized for projectors above 1,500 lumens. This device is in a larger package than the DLP470TP, which allows it to withstand a greater amount of heat, enabling brightness up to 4,000 lumens.

With a tiny 0.47-inch diagonal, you can display 8.3 million pixels in a smaller design for a cost-effective display solution for the mainstream market.The DLP470TE and DLP470TP 4K UHD chipsets display four pixels on the screen per micromirror, enabling the smallest 4K UHD digital micromirror device (DMD) that DLP technology has to offer. With a wide range of lumens capabilities, the DLP 4K UHD family of chipsets allows you to broaden your 4K UHD display possibilities by developing systems that use the chipset’s high brightness capabilities and small form factor for applications such as laser TV, digital signage, gaming, corporate and education projectors, mobile smart TV, and more.
So as long as you have the 8million pixels on screen, it's considered 4K UHD.? or is that an over simplification of the matter

The 4K TI chip they will have to use to fit in the small case can only handle 1,500 lumens, plus a battery is not going to handle 2,500 lumens and the heat created by the bulb necessary would overwhelm the unit. This would have to be about a 250 watt led! They were almost believable at 1,500 lumens, but at 2,500, NOT.

But the DLP470TE version is the same as the DLP470TP, only build in a bit larger package and able to handle up to 4000lmn. Extreme High Power (XLamp XHP50 en XHP70) LED's are seen at 20W for 2500lmn already.
Yet I don't think they will get 8 hours out of that battery too.
