JVC RS4500 (native 4K laser projector)

[Madfloyd]

Received my 3D glasses yesterday and watched a bit of The Walk this morning.   3D was impressive. Not sure how much I'd want to watch 3D movies but it did seem to work rather well.  I had to put the laser in HIGH mode (since the glasses darken the image substantially).

Afterwards I watched a little bit of 2D material with the lamp on HIGH.   Yes, it's loud, but boy the image was mega- impressive.  Now I think I want to build a hush box.   Kris, since it sounds like you have an idea of what you're going to do in this respect, do you care to share how you would approach this?

I rarely use the dynamic laser since it is very distracting and imo needs a lot of improvement.  Of course with 1080p content we now know (courtesy of Kris) that is very problematic.

Interesting that you find it distracting. I find it works quite well most of the time. Then again, I haven't found any D.I. that works 100% perfect 100% of the time.

It probably depends on the material.  On Underworld UHD it worked great.  I'll have to try it more with 4k material (of which I've only watched one movie so far and sampled 3 or 4 others).   Most of what I've been checking out is 1080p material since I have a movie server with thousands of titles which I can watch instantaneously (no loading times etc) and I can surf around quickly.

In that case, if it's not working with 1080p, I'd switch it off. One thing that's strange though is I don't see it misbehave with HDTV, which is 1080p. Then again, I don't watch a ton of HDTV either. But what I have watched seems fine.

I tried the dynamic laser for the first time in a while the other day and immediately spotted a lag jump.  Turned it back off.  I don't miss the dynamic laser at all, although I would like FFTB.  There should be an option that just gives that and no other dimming...

Mark, when you say 'lag jump' do you mean missed video frames or are you describing changes in brightness only?

The scene changes and a split second later the dynamic laser changes.  Lag.

That sounds more like how the dynamic dimming worked, before the firmware update.

Anyone got a calibrated Z1 where they can run and take a pic of this testpattern.?

I'm waiting for Ray to have his 4K UHD patterns available on UHD Blu-ray - which he said are just about ready. That and I'm still waiting on my thumb drives from Amazon. I'd rather play them through my source device ( the Panasonic UB900 ) on disc though, same as the movies I watch.

The internet somewhere.. Dont remember the site, try google UHD testpattens, and im sure you will find it.

I checked its UHD resolution so it will do fine for a projector resolution test, wich is easy to take a picture off, even with a lousy cell phone camera.

It's working much better after the firmware update, that's for sure.

Masciola HDR Suite.

Why are you pushing on with asking if someone can take screenshots of the 4500? Are you considering buying one or are you just looking for something to nitpick?
