JVC RS4500 (native 4K laser projector)

I've got some screen shots here - https://discuss.avscience.com/?topic=292.new#new

Would you be able to download or run some of the UHD patterns from youtube and snap a shot of those?

I'm waiting for some thumb drives to show up from Amazon, then I'll download some 4K test patterns.

For those near Rochester NY, If you want to see the RS4500 in action along with a Triad Silver sound system in a treated room, come to our store. The room is pretty much finished, except for Atmos speakers. Still waiting on Triad to start shipping the Silver/9 RotaSat Atmos speakers. In the 2nd room (media room), you can view an RS420 or RS400.

The building construction is still going on, but our area is pretty much complete.

Who calibrated it?

I'm picking up my new RS4500 tomorrow and hope to be installing this weekend (as long as the mount shows up in time!). I will post some measurements to see if they still stack up to the ones I took for the review.

Excellent - you must be so excited!

I'm still trying to get used to mine (coming from 3 chip DLP) and looking forward to seeing what I think after having it calibrated this coming Monday.

I'm also trying to decide whether to use my ISCO III or zoom.  Anyone have any thoughts on that?

[Kris Deering]

Haven't used an anamorphic lens, so no experience to draw from there. Mike is using an A-lens with his though.

Just got a UPS email saying the mount shows up tomorrow, so definitely on track to install this weekend!

I zoom, but I've done the same with my Sim Lumis Host, Sony VW600 and RS600 too.

Zoom here too.  The Z1 is very slow to zoom, but seems more accurate than my Sony 1000 was.

I use laser mode/iris to brightness balance both zoom modes for consistent presentation.

Who calibrated it?

No one yet. Just running settings from Kris Deering.

Glad to hear you're doing separate calibrations, a must for this to work properly. The zoom memory for the Z1/4500 is definitely slower than the RS620 I'm using now. It only takes a couple seconds to adjust. I'm using a Lumagen Pro in my setup so I rarely have to use the memories as I just use the aspect ratio control in the Lumagen most of the time. But if I know I'm gonna watch a whole film that is 1.78:1 I will change the zoom to try and eliminate the scaling (though it is so good in the Lumagen I don't think most would even notice the difference!).

Our demo rooms are ready for viewing. Here is a picture of the screen in one of the rooms. Projector is RS4500. Our V6 fabric for the screen, Triad Silver speakers and SVS subs. Also picture of the RS4500.

Very nice! Love the 'circuit board' wall treatments!

Yup.  Also using seperate 3D LUTs for 1.78 image and 2.35 image to compensate for changes caused by MID/HIGH laser and iris.  To be honest, you'd be hard pushed to see the differences but the differences can be measured, so they are there.  I could make life a lot easier and just use one LUT but I'm kind of nerdy about perfection!

And will probably set up two more LUTs for HDR once the Lumagen Pro HDR Intensity Mapping update arrives...

Also use the Pro, but as I tend to only watch one movie at a time I always zoom to the required aspect.  I had tinkered with changing aspect via the Pro but was always aware of aliasing on diagonals after shrinking.

Pardon my ignorance, but what is a LUT?
