JVC RS4500 (native 4K laser projector)

[AVSCraig]

I just went true the review, and wondered why the screenshots was so full of edge ringing and artifacts?
Its not lack of image resolution on the shots, so is the images processed to look that bad, or is it actually just capturing whats on screen.?

I snapped a few shots of my own projector to compare, from the Blu Ray Oblivion, 1080P on a CRT projector, and even been trying adding massive Darbee (70%) and also some edge and detail enhancement, without beeing able to reproduce the amount of distortion shown on the JVC Z1 screenshots..

Would be interesting if someone else would take a shot at that Oblivion scene from a Z1.

Does anyone know if the RS4500/Z1 can handle the vertical stretch so that an anamorphic lens can be used?

So would be nice if some of you guys would snap a few fast pics of your setup of the Z1, the more shots the better, it gives the rest of us a idea how it really looks.. I think its worth much more than all the subjective opinions, specially if you include some good testpattern shots, like croma multiburst, SMPTE pattern, zone plate and so on.

That would require good camera equipment, which I'm lacking. An iPhone 4 or the cheapest Canon point n shoot probably won't add anything useful.

Im sure some or one of you guys here that have a Z1 have a decent DSLR camera. even the point and shoot camera might do quite a lot better than the shots posted, and the cell phone will do fine for a SMPTE pattern shot, as it will have no problem showing if there is color shift/ distortion on the 1:1 vertical/ horizontal resolution, wich is quite normal on non DLP projectors.

Javs over on AVS talked about the pictures and gave some pointers on how to improve the captured images.

In one of the RS4500 thread on AVS, there is the same 4K pattern, shot with an iphone 7 and it even looks better than the shot in the review. Here is a link.

That shows the heavy color shift on the 1:1 horizontal lines like in the video of the SMPTE pattern, anyway it will be interesting to see somebody step up the game and fully document how the Z1 handle with different settings and modes, and include both testpatterns and movie content, whats been represented so far only shows that the Z1 has some problems resolving a UHD source signal.

Black text on a bright background as posted is also a very good at showing off enhancement processing distortion, if its possible to eliminate it, or if JVC has gone the SONY way.

Thats easy snapped  with a cell phone, as shown on AVS.

I believe earlier in this thread, Kris posted that the RS4500 fully resolved 4K test patterns and that the RS4500 fully resolved 1080P test patterns. He said that the Sony 4K units, had problems fully resolving the 1080P test patterns.

Different people define resolve in different ways.. If the green color distortion on the 1:1 horizontal line pattern is a limitation in the panels, or processing, ill say it cant fully resolve UHD, and ill also say that it will be hard to find a projector, or display that actually resolve the source material 100%, ill even claim that its has never been made..

Would be interesting to see where this new piece of toy is on the resolution scale.

If there is someone with a Z1, a camera and some good testpatterns + movies, it would be interesting for some of us mortals to get some insight into the capabilities of the latest tech.

Yes, I use an A-lens with my RS4500.

I do not have any 4K test patterns. Only 4K source device I have is an Oppo 203.

Im sure you can find some good UHD test patterns online and run them from a USB stick in the OPPO.

Youtube already has compression, so that would not be a good option.
