JVC RS4500 (native 4K laser projector)

[Kris Deering]

I'm going to 2nd the clarity and clean image. Forget 4K Blu Ray's for a second. Yes, I know this is a 4K projector, but with over 480 Blu Rays in my collection, I'll probably be watching them for the rest of my life. Since Kris reported that the RS4500 was doing excellent upscaling, I did a test last night with my Oppo BDP103 in " source direct " mode. First I watched some of " Avatar ". I watched first upscaling to 4K from my Panasonic UB900, then I switched to the Oppo outputting 1080p. I think it looks ever so slightly better from the Oppo " source direct ". I don't need any motion enhancements on at all - motion looks very good. Super clean image. Virtually no picture noise. Excellent detail. And at least 2 fade to black moments that were very nearly as dark as my RS600 ! Mid laser power, -7 manual iris, mode 2 laser dimming.

For those that complained that the e shift projectors had a " busyness " to the picture, once again, that is non existent on the RS4500 for sure.   

I switched to " Prometheus " next. It's a good dark movie " torture test ". I have to say that 95% of the time, dark scenes look just fine compared to my RS600, and better than my VW600. Bright scenes - no contest - this Blu Ray also looked extremely detailed and super clean. And there was another fade to black that blacked out my theater.

I've got all MPC settings at 0, Graphics mode 4K, all motion enhancement off. Picture mode - Natural, BT.709, 6500K. Gamma - 2.4. Input level 16 - 235. Manual iris -7, mid laser power, dynamic dimming mode 2.   

Graphic mode should be 2K if you are using the Oppo in source direct. I've gotten to the point now that I turn off dynamic dimming except for really dark movies. This is what I did with my X750 as well. I rarely notice any issues with dynamic dimming, but I'd rather never see anything at all if I don't have to.

Not a 3D fan, but decided to check it out and see how it looks on the RS4500. With the lamp based versions, I see flicker. The flicker does not bother me a whole lot, but with the 4500, I did not see any flicker. Nice image and I did not notice any ghosting in the 40 minutes of 3D that I viewed.

Interesting. I used some of my 3D titles that are prone to ghosting and had to turn the crosstalk setting down to like -7 to get a 3D image that was devoid of most if not all ghosting. Performance doesn't seem to be quite as good as the X750 overall here, but setting the crosstalk down quite a bit helped a lot. In default mode I saw a LOT of ghosting with "Despicable Me".

What is the affect of having Graphic mode on 4K for Blu Rays, and I'm guessing it needs to be manually changed for 4K UHD Blu Rays to Graphics Mode 4K ?

And on the other hand, I wonder how 2K Graphics Mode affects 4K content ?

You are telling it what the resolution of the input source is. So for your HDR mode or 4K mode, select 4K. For 1080p sources using 2K.

Makes sense. I was just curious if there was a visible affect - at least on test patterns. I suppose switching is automatic, seeing as it is in the appropriate user mode !

If anybody wants to come to south central Kentucky to see the RS4500, let me know. Craig has his in CA and shortly we will have our demo theater up and running, with the RS4500 featured in that room.

Mike;

I would like to drive over and see the RS4500.  I live in Northern Virginia, and would like to drive over, after Winter is over.  When will the demo room be set up with the RS4500 for viewing?

Shell of the room is completed. Working on columns now, Once those are complete, we will install all of the equipment. I think we are talking less than a month. I will post, when room is completed and ready for viewing.

Maybe when we drive down to Tennessee to check out houses I should make a pit stop and see it Mike!

When are you coming down? I am about 2 hours north of Crossville.

Here's a copy of what I just shared over on the AVSF thread after hearing from my JVC contact yesterday:



Some comments were passed on to JVC from the calibration guy at Mojo Media who undertook testing the Z1 this week. They are still yet to test beyond 2K material at this stage but are reporting that they are impressed with black levels, sharpness, Lumens on screen and general colour accuracy. However as per I think all of us here, DCI mode was noted as was woefully inaccurate with standard factory settings but improved greatly when colour temperature adjusted and saved in custom user setting, though still only 90% accurate in DCI after adjustment applied apparently. The next bit of feedback kind of makes me wonder what these guys point of reference benchmark for performance is and also the lack of key information like screen size and gain as apparently there were "no complaints with expected on screen brightness/NITS either before or after adjustment which is interesting compared to your findings and others on forums". Also added was that "All other primary/secondary colour measurement tests accurate" unsurprisingly. The JVC contact then said the lead calibrator passed on his 'settings' which may be useful for me. In reality this was simply the base picture settings that really is totally irrelevant really since my own screen size and gain are going to effect what contrast I run say and why would I run someone elses contrast setting (used on top of their own custom calibration as well) when I can throw up white level pattern any time I want and set my correct contrast in about 30 secs. They had things like -15 contrast in their calibrate rec 709 mode, which struck me as really odd to say the least, but again I have no idea of their calibration results or screen size / gain at this point. There was also a shot of settings for their calibrated DCI mode which had -9 contrast and gamma at 2.6. They have though put me in touch with the lead calibrator to compare notes with which will be interesting. Another post production company tell will be commencing calibration of another unit apparently next week and he too is more than happy to discuss his finding and compare notes.

Perhaps most interesting is that JVC had a conference set up tonight between the global JVC sales offices and the factory D ILA team to address current market feedback including your own findings which they are taking very seriously. I'm told direct feedback will come back from the factory over the weekend. There's also no ETA on when we here can get our hands on those simple exhaust ducts, however JVC continue to push the issue with the factory.

I am not a big 3D fan, but 3D with the 4500 is very good. With the RS600 I would always see flicker, that I would have to ignore. With the RS4500 the image is very calm and stable, no flicker.

[mark_h]

I see flicker in the brightest images, eg skies, but otherwise, yes, it's the best 3D I've personally seen.  But still not a fan and won't be spending any real time with it.

Invitation is open for me as well for anyone interested in seeing this projector in action at my home local to the NY/Northern NJ area or feels like taking the ride.

Here is a quick snap shot I took from Oblivion on my iPhone 7 plus. This projector is absolutely amazing. Oblivion on the VW1100 never looked this good. I've been going through my collection of BD and UHD films and I'm just in awe. If anyone has any requests for images (movie and chapter) and I have it, let me know. I'll be happy to post.

Image on my ~10.7ft 2.35 Seymour XD screen. Low laser power. Not the best shot from an iPhone but gives you a good idea. Love this projector.

How many foot lamberts in low laser on that screen ?
