Most "4K" projectors are actually fake 4K. The current common real-4K ones are only the JVC N5,NX7,NX9 and Sony 870,760 and 265 (or close.. their numbering is weird).
But there are a bunch of alternatives that "simulate 4K" in a way that I find at least interesting, and also a bunch of ultra-short-throw projectors are surprisingly cheap.
So for example:
My current ideal 4K projector seems to be:
JVC NX9 - 18,000 GBP - 2200lm - 1:100000 native contrast
since I really need the lumen and the cheaper native projectors all are below 2000 but ouch, that price is pretty much a dealbreaker...
But then there's (as just an example, feel free to look at epson or whatnot)
Optoma UHZ-65 - 3000 GBP - 3000lm - 1:200000 contrast (1:2000000 listed, but I 'dynamic' so I'm multiplying by 0.1)
And what about
Vava 4K Ultra Short Throw - 2200 GBP - 5000lm - 1:150000 contrast (1:1500000 listed.. dynamic.. x0.1)
I'm cutting corners here but can someone explain to me what I'm missing? A few thoughts:
- Optoma: I guess the DLP trick drops absolute sharpness a touch, but interleaving is a technique as old as the first ever TV just because it's so cheap and effective. If I had to guess the downside of this technique if it were absolutely the only difference, would only be a few % sharpness. Of course then you have DLP vs other tech, but the Optoma is laser-based.. so.. eh?
- USThrow - uh, well 'clearly' UST is kinda hacky where the image needs to be deeply distorted and probably some tricks with contrast/brightness to fix the effects of beaming 'straight up'.. so I can kinda imagine it ruins things.. but does it actually? Or does it just 'feel wrong'..
Anyone able to explain stuff to me? =) Has anyone compared the technologies side by side? Why is 18,000 reasonable?
