JVC RS4500 (native 4K laser projector)

[ARROW-AV]

EN4K is a good AT screen. I would also take a look at V6 DreamScreen. Really like that material.

That's also on my short-list and in fact I have a 4.5m x 2.5m roll of it sitting right here waiting for testing and evaluation head-to-head against the others on my short-list, which is as per follows... in no particular order:

(1) DREAMSCREEN | V6 UltraWeave AT
(2) SEVERTSON | SAT-4K
(3) SEYMOUR SCREEN EXCELLENCE | Enlightor 4K
(4) FALCON SCREENS | HORIZON

Looking forward to measured light output. What is spec'd would work for me... but what's the real world output?? Congrats to those that have them!

You will be seeing light output measurements in just about every which way that's possible being posted on here ASAP following my evaluation tomorrow so watch this space... My review won't be as professional as Kris' review but will hopefully provide many of the answers and fill the void whilst everyone is waiting for Kris' review, myself included!

I dug up an old AEMC light meter from years ago and tried to take some readings. It proved pretty useless unfortunately as anything but next to the screen proved too much for it. I may purchase another one locally tomorrow if I get a chance and try again.

Just to let you know, after a few posts have been approved, you do not have to go through the verification process. I have approved your first three.

Stand next to the screen, point the meter back at the projector with a 100 IRE full field test pattern on, and measure the lux reading. Thanks.

So, got the Z1 up and running today... Sharp as a razor, that´s for sure...! Light output has not impressed me thus far, seems to be lower than the prototype? I only had a short time reviewing it, and putting the laser at high, iris at -8 and flicking between laser modulation 1 and 2 it does look quite nice. Still, not "sold" quite yet, need to get it calibrated ASAP.

I´ll revert with more impressions tomorrow!

What size / type screen are you using again ?

[AVSCraig]

On the RS4500, lens memory is now installation mode. It's on a separate page in the menu.

I am sure it is DreamScreen V6.

I am sure it is DreamScreen V6.

Doh !

Calibration isn't going to change much as it is already 99% there out of the box. But it can confirm your settings in terms of desired fL on screen.

Hi Kris,

How is it dong this - do you know? Is it from a calculation using data you give it, or an in built meter?

last week I decided to go over the entire Hobbit and LOTR saga again, yesterday i took the opportunity to watch The Battle  of The Five Armies on the JVCZ1   
This looked amazing, took me right into the movie, today I watched gravity and i could not help thinking that it looked a bit dull.
I made a promise to myself to not go around and start messing around during the movie so i rode it out and then started looking what I was missing.

Turns out I was on low laser where i should be on mid with the iris closed down to about -8 to get the desired output i want.
I also got a feeling that some minor black crush was there but when putting on the Murideo in the chain the pluge pattern was still spot on. 16 invisible and 17 just disolved, so everything should be right, I am running a gamma of 2.3 I will try to adjust the gamma a click or two on the sliders in the gamma menu and see what happens.
I ran over to my other room and fired up the epson on the same scenes where I had my doughts, I had the impression that I had some more details in the blacks there also with the pluge pattern correctley set up.

So if anyone wants to try and compare some dark scenes with as much detail as possible to see what you come up with.
It could be that it is just the better blacks of the JVC that make me doubt, have to compare the side by side to make sure.
If I had the time one of the flowing days I will do that.
Have fun watching an playing with the new toy guys.

It's a 14 feet wide 0.8 gain DreamScreen V6 AT in cinescope format, so it's a pretty big screen indeed... I'll try looking through some familiar source material tomorrow, and I'm not saying it's 'dim', I was just a little surprised initially, might be me having just read too much on forums lately, and I also have the rs600 to a/b compare to which is kinda interesting too...

Mine is 9 feet wide and I am on mid laser and iris about -8 in SDR on a screen research acoustic transparent screen (with black backing behind it) gain should be about the same as yours.
In HDR I use mid laser and iris full open with the HDR color space, looks pretty impressive to me on 9 feet wide.

That's a pretty big screen - 83.4 square feet. 1600 lumens doesn't get you to much over 15 foot lamberts.
