JVC RS4500 (native 4K laser projector)

[Madfloyd]

I would rather have better pixels than more pixels.

That is true, but owning an RS4500 the 4K panel and it's tack sharp clarity is one of it's greatest strong suits.  Seems to me that jumping to a native 8K panel is having the buggy before the horse so to speak?

I would rather see a native 4K unit with increased contrast, more lumens and full P3 w/out the light loss than a native 8K unit.  Unless you are sitting 5 feet form the screen I just don't see how going to 8K will really deliver much improvement over native 4K w top tier optics like the RS4500 has. 

I have never personally seen 8K so maybe it will provide a "slap in the face" improvement but I am skeptical.

I don't see in any of the forums where people with native 4K units are clamoring for more pixels so it just seems like maybe more of a marketing ploy than a real technological advance?

I wonder if JVC could change the DCI P3 color filter from providing around 103/104% of DCI to 98/99% of DCI and pick up a fair amount of brightness. If JVC could get the loss down to around 20% like the lamp based units, then more people would use the DCI P3 filter on the 4500. More native contrast would be nice, but if I had to pick between same light output and more native contrast vs more light output with same native contrast, I would pick more light output.

Can I say given we have zero info on what else the Z2 will bring to the table other than the quoted 8K native, there's not a lot of point right now in making 'I'd rather have' type statements. I agree though, 8K alone doesn't excite me much, especially with the price tag to match. I mean we'd be looking at upscaled 4K and HD content for years to come, its not like we're going to have matching content to really get the full advantage.

Just got my 3rd replacement Z1/RS4500 today.....Now i get to start from "0" hours again..

Everything is speculation so it's just discussion and banter, don't see the big deal really.

Good luck!

Third times a charm !

Don't break this one!

Is it me or is this convergence not great?  Is a pixel either direction within spec?

I can't tell anything about the convergence from that screen shot of the menu. And you need the projector to be on for at least 30 minutes before you look at convergence - maybe he just turned it on and it's the very first minute of operation. Plus, he hasn't even had time to make any adjustments or convergence corrections.

I am on my 3rd unit as well.  the other two were defective for two different aberrations neither of which were panel related and they were noticeable during the first hours of operation.  As far as convergence goes my first unit was pixel perfect.  The second one, the red was off by about 1 pixel and the 3rd unit was off by about 1 red as well (it is defect free to date and seems just fine).   One or two pixels off you will not even be ale to see it from outside 5 feet from the screen depending upon the size.  I can also say that while watching material I could never notice it. it was only when displaying patterns or with the menu that I could see it standing on to of the screen. 

I also made the mistake of checking convergence too soon on my 3rd unit as it did settle in some after a few hours of operation. 

I absolutely love the image this projector throws and it's the only reason I gave it a 3rd chance rather than take a refund.

[AVSCraig]

It throws a stunning image ! I love mine every time I turn it on. I have a big " fast car " movie marathon coming up this week - " Rush ", and 5 " Fast and Furious " movies - the last three in 4K !!

The projector had been on all of 5min!  So convergence is never going to look correct. I basically fired it up, zoomed and a quick focus to take a pic of the menu .

What problems are you having?

My original unit ,s lens was damaged due to fitting the supplied ( faulty )  lens cap. I DO NOT recommend anyone use the cap....the clearance from the factory is less than "2mm" .

The second unit had "Debris" lens contamination somehow during shipping.......didn't even fire it up , just repacked it after taking pics and then waited for the 3rd unit to arrive.

This is how my 2nd unit arrived ( see pics) ...straight out of the packaging ...somehow the lens was contaminated..

My 3rd unit has a perfect lens and absolute "Tack" sharp focus across the whole screen !! 

Oh ! @AVSCraig  ......it smells NEW
