Outside of the initial inspection and ‘ohhh look 8K’ you wouldn’t see it? Only person I can think of is @kenshingintoki but even he might find it uncomfortably close.
First the panels cant do a 1:1 on off pixel, 2nd the lenses dont have the MTF to fully resolve 4K, if you seen a N series up close with a 1:1 pixel phase pattern you will understand.Why do you say they can’t resolve 4K?
But that doesn’t answer why even offer it, like how close must you need to sit from the screen to even see the added resolution
I suppose that’s also the reason for HDMI2.1. As an old man I never realised gaming was that big but clearly it’s a huge market even in the projector world.I think scientific tests estimated around 3.8k was the optimum resolution based on seating position 20/20 eye sight etc, and 8K is not really needed for film, but I expect it is there for the gamers. 8K is a big thing for the PS5 and Xbox Series X. You are often focused on a part of the screen at any one time rather than the whole screen, so 8K can work here.
4K vs 8K will depend on the screen size, pixel fill factor, MTF and so on, if you run a 800" screen with 8K projector who have a 50% pixel fill and high MTF you will for sure see pixels.But that doesn’t answer why even offer it, like how close must you need to sit from the screen to even see the added resolution
My guess is that JVC likes to use what they have learned from producing projectors over the years, so now when they have managed to create good native 4K panels, they also want to use their e-shift systems and add a propper 8K pixel addressable e-shift to create a pixel less image with a look and theoretical resolution close to the pinnacle of analog film.But that doesn’t answer why even offer it, like how close must you need to sit from the screen to even see the added resolution
CRT is great and wonderful but it’s had its day, very few want to give up the space or re-enforce the joists to hang one from the ceiling.4K vs 8K will depend on the screen size, pixel fill factor, MTF and so on, if you run a 800" screen with 8K projector who have a 50% pixel fill and high MTF you will for sure see pixels.
A good CRT projector on a 130" screen running 1920X1080 you just see a painted image on screen. And comparing a JVC N series with good upscaled 1080P vs native 4K source, you wont see any added resolution/ information even if you press your nose against the screen.
The point is you can not simplify it as only pixel count if you dont look at the mtf and panels capability to have 1:1 on off.CRT is great and wonderful but it’s had its day, very few want to give up the space or re-enforce the joists to hang one from the ceiling.
In the REAL WORLD 4K is all that’s needed for watching movies and NO ONE has a 800” screen in In their home. Ricky made a valid point about gaming as I don’t game I can’t argue either way but for movie watching I doubt the world needs 8K.
8Kx8K I believe is what Tim Sweeney (Epic CEO and mad programmer) has stated is above what humans can resolve and once we get there will be indistinguishable from looking through a window (pixel wise). Although I can’t remember if that was also in relation to VR where you are looking at a screen through magnifying lenses which needs even higher resolution.CRT is great and wonderful but it’s had its day, very few want to give up the space or re-enforce the joists to hang one from the ceiling.

My argument only really works in the domestic home environment where screen size very seldom go beyond 150-160” but your comment about making the image look even more natural is interesting. I’ve never thought of 4K looking unnatural in appearance the times I have viewed them but I look forward to seeing the difference based on what your suggested as a possible reason for it.My guess is that JVC likes to use what they have learned from producing projectors over the years, so now when they have managed to create good native 4K panels, they also want to use their e-shift systems and add a propper 8K pixel addressable e-shift to create a pixel less image with a look and theoretical resolution close to the pinnacle of analog film.
Theoretical 35mm film resolution is about 6K
Theoretical "15/70" film (IMAX) resolution is about 12K
more pixels do not only add resolution but also adds how many colors and gray tones can be shown at once in each movie frame or picture.
So I guess a propper 8K projected picture can be made to look even more natural than a 4K picture, even if our eyes are not fully capable to resolve the resolution from our normal viewing distances.
I do somewhat agree with you Luminated, at the moment 4K seems to be good enough for home cinema with the current video and movie sorces.
It does make me laugh the whole 20000+ hour thing because I’ve yet to meet a single person who would ever need such a thing, I’ve had my Epson since Jan’19 and it’s only got 840hr on the bulb. LOLEven if Bill Gates did not say something like "640K of memory is enough for everybody", I do like to remember moments in time when "truth" like that existed. Because as long that there are customers, smart salespersons, and good engineers out there, there will be an evolution in the AV and digital world, and it can be hard to know what's good enough for a projector with a light source of 20 000+ hours.
It’s marvellous!It's alive!!!!View attachment 1578093
Some people use them like televisions for several hours in the evening.It does make me laugh the whole 20000+ hour thing because I’ve yet to meet a single person who would ever need such a thing, I’ve had my Epson since Jan’19 and it’s only got 840hr on the bulb. LOL
And you can spot them coming down the street.Some people use them like televisions for several hours in the evening.
Also had a quick look at NZ7.....just got back in the door 20 mins ago and am a bit zapped. Not got full in depth stuff to tell you other than i liked it. More if i have time tomorrow
Holy crap!! How big is that?i know you all love a screen shot....lolView attachment 1578139
More to the point, what is the source and material being used?Holy crap!! How big is that?
Gordon how big is your screen?i know you all love a screen shot....lolView attachment 1578139
I reckon that will look pretty decent on my shelfIt's alive!!!!View attachment 1578093
Or all day gaming etcSome people use them like televisions for several hours in the evening.
Is that with or without e-shift and do you notice any difference but your professional eyes are a million times better than mine.i know you all love a screen shot....lolView attachment 1578139
At 25k it damn well ought to!I reckon that will look pretty decent on my shelf
