The projector is so affordable. There are a lot of backers.
Bad thing is if you purchase, you ll receive the product only on september
50 % off is still unbeatable

It is based on pixel shifting technology. The one that epson, JVC uses.
Native 4k is only with sony for now, which is super expensive.( relatively much cheaper compared to the 25k dollar cost before )

Any point on why buy/not buy this product?

I backed this thing sometime back, let see how it goes. At this point its not even clear which DLP chip it's going to be using.

Looking at the stretch goals, "Lumens of 2500 if 700k USD is reached" it looks like they will be using the new .47" 1080p x 4 pixel shifting DMD (DLP470TE) now. This DMD is the same as the one used in the BenQ HT2550 and the black level performance of this DMD is subpar according to reviews.

There are some backers asking to improve the uniformity. Is it imporant?
And contrast ratio 50000 : 1 is good enough?

And out of 10, How much do you recommend this purchase ?

If you have the choice of buying Mi mijia 1080p projector and Ntech 4k projector, which one would you prefer?

Uniformity is very important, at the current 75% it can potentially have visible vignetting. This is probably caused by the tiny lens they are going to use, I haven't a chance to see the reference implementation from TI yet, they are being very secretive about it which is quite strange. Usually all TI DMD's have the reference implementation made public.

The MI Ultra short throw is a basic 1080p .47 DMD like the ones used in the XGIMI H1, JMgo V8 ,LG full HD LED projectors etc and buying it depends on your need. If you need a ultra short throw laser projector then the MI and the JMgo S1 pro are your only choice in that price range. I personally do not want like ultra short throws as they are very sensitive to screen defects and you need to invest about 3 lacs for a screen to make them look good in a living room environment, DIY retro reflective screens like the black widow paint will not work and will cause terrible hot spotting. And on top of this these are single laser projectors which means they still use a colour wheel and as a result rainbow effects will still be there.

Further Indiegogo is a crowd funding website, when you pay the money you haven't bought anything you have simply invested in the company (n-tech in this case). They promise that in return you will get a projector when they are up and running, if they crash and burn so will your dreams of owning the cheapest 4k projector around and in some cases you wont see your money again. So buy it only if you feel "lucky" :cool: . I see potential in the company and hence invested in it.

Seems too good to be true!
But, 540USD does definitely seem fine enough to risk.

Confused.
How many are thinking of backing this?

It carries a risk of losing money. The projector seems promising. The seller might keep up his promise and ship it. Or He might abandon the project and refund/ or not refund at all.

Some 4 or 5 have backed from this forum i guess.

If using pixel shifting then its not a native 4K projector. its 4K UHD projector. Also the cheapest native 4K from Sony is at 5K$

Yeah, but its a good deal considering the position of the current market. True 4k aint gona get cheaper until 8k comes in . Or something entirely different like a "Holographic Projector" gets introduced

Technically this is a native 4k projector so its the UHD65 you own. If a chip can put 8.3 million distinct pixels on the screen (3840x2160) irrespective of how it does it, it is considered 4k. Whether this is the right thing to do or not I don't know, but that's how its done. On the other hand 4k enhancement projectors from JVC and Epson are not "native 4k" as they can still only put out 2 millions pixels on the screen and the "enhancement" is technically just software scaling.

I believe UHD 4k is a resolution like FHD 1080p.
"Native 4k" is to differentiate "downscaled 4k" 1080p projectors in the market.
True 4k vs Pixel shifting are technical differences.

Not exactly - Native 4K is 4096x2160 and the aspect ratio is 17:9 instead of the standard 16:9.
UHD is 4K coz it can produce the 8.3 million pixel as its required to be qualified as a 4K projector.
In short the consumer version of Native 4K ( 4096x2160) in 16:9 aspect ratio is 4K UHD - which is (3840x2160)
Thats why all 4K TV's are 4K UHD

Ah I see you want to be pedantic. Well in that case "4k" is irrelevant in the consumer realm at this point in time atleast. As the highest quality source you are going to find in the consumer realm is a UHD Blu Ray which is 3840x2160. And to top it off as far as I know the HDMI standard for 4k is 3840x2160. And the Sony may have the "pro" 4096x2160 lcos chip but it's not so relevant in the world of "home" video as source and transmission standards for home video can't use them. Bottom line is native 4k for home video is for all intents and purposes 3840x2160. We could all change and say native UHD rather than native 4k but what exactly would that achieve?
