JVC RS4500 (native 4K laser projector)

[Pultzar]

Here is a nice fact for people. I think most people know how QC works. Usually a set percentage of units are pulled and checked to make sure the units randomly selected meet specification. Well here in the US, with the 4500, that percentage is as high as you can get. Yep, 100%.

Considering that the projector is the price of a pretty nice car, they better test them all!

It was me (Mike) that answered you and yes that is based on the 2.40 width of your screen. You will have much higher brightness when shooting 16:9 onto your 2.40 screen.

One of the things I do on my current Sony (1000) is use HIGH lamp mode for 2.35:1 zoom, and LOW lamp for 16:9 zoom.  This has the nice side effect of normalising the brightness between the two presentation modes.  I'll be looking to do the same with the Z1 through a combination of laser power/iris.

You can store lens settings, masking, fine convergence and anamorphic modes in a user memory.

They may have changed how you do this - looks like " lens memory " is now " mode " ( see page 50 of the owners manual ). Lamp power and other settings would be under " user " settings.

Very glad to read all of these positive notes from the actual production models! Bodes well for the future.

Congratulations to everyone who has gotten theirs, or have them on the way. Seems like an incredible machine indeed.

In case anyone is interested, with respect to my handson with the JVC RS4500/Z1 this Tuesday/Wednesday, in addition to posting comprehensive measurements of the JVC RS4500/Z1 in action, I will also be including a direct side-by-side head-to-head comparison versus the SONY 1100 and JVC X7000/RS500, wherein I will be including the comparative measurements and relevant data for these also as part of my review report.

Where I am intending on carrying out my measurements over the course of Tuesday (with a run over into Wednesday if the projector arrives late from JVC) with the intention of posting all the details on here sometime on Wednesday

Looking forward to that, along with your subjective opinion.

What kind of screen and environment?

[ARROW-AV]

What kind of screen and environment?

We are currently mid-process of constructing our new demonstration centre so I will be carrying out this exercise at a good friend of mine and business associate's demo rooms; where I will have the choice of three screen sizes, namely circa 3 metres, 3.8 metres, and 4.5 metres wide; with I believe Seymour Enlightor AT screen material, but I will be confirming all the details in my review. And the environment will be a properly blacked out room with low level ambient light reflections.

I'm up and running as recently posted on AVS. I'll add also that the unit has quite a bit of fan noise in high laser mode, not nearly as much in mid. I'll be experimenting with all modes as the evening goes on. Have to get back to it as it's already 7:30pm!

Keep in mind that EN4K is close to 0.75 gain. I have EN4K.

Though it is not listed on Chief's site. They do make a custom mount for the RS4500. I mentioned this early on in this thread. The mount is VCM105J. Kris is using this mount and has provided some pictures. Really like that it has so much adjustability, for centering the projector.

Thanks for the headsup Mike! I believe this is not the 4K version but one of the other two... I will obtain confirmation on Tuesday. That said, he's changed at least one of the screens since my last visit so he may have installed the 4K version... But either with I will be taking comprehensive measurements that will encompass accurately measuring the screen gain as opposed to relying on the published figures which you can Craig have astutely pointed out are almost always so inaccurate that they are meaningless. So I will be measuring what is it's ACTUAL gain and not whatever B.S. figure is listed... But Sssshhhh don't tell MR SEYMOUR I said this!

And I am interested, what is your opinion on the performance of the EN4K as a material? It is in fact one of four that I have short-listed for assessment and so I would value your opinion... How would you rate it?
