I'm hoping it turns out well. I have an RS57 coming (upgrading from the RS4810). I'm hoping to enjoy the improvement in the native contrast alone, but I also want the idynamic iris to be an added bonus and not a useless marketing feature we have to turn off. That preproduction review has caused some concern, but I'm hoping they improved it for the release models.

The observations of those forum members who saw it at CEDIA are helping to to temper that concern, but we really won't know until someone gets a release unit and looks at it. Hopefully we'll be getting some feedback soon.

I was looking forward to finding out for myself tomorrow, but with the shipping delay and then my own holiday travels plans I won't be able to receive delivery of my unit until next Monday.

They seemed to love the DI.

That article is 2 months old and is most definitely a pre-production unit. I'm sure the DI has changed since then. Hopefully not for the worse. Also it doesn't really say which parts of the movies were shown. For instance, if there weren't sudden changes in contrast within the image, the DI wouldn't need to function quickly to compensate, thus not truly showing how it performs. One needs to spend a few hours on various types of content to truly get a sense of how it performs. I'm sure the clips shown were picked specifically to show off the projectors high points, not clips that will paint the projector in a bad light.

I just got on-board with this PJ! Upgrading from my short lived Mits HC-5/HC9000.  Thank you to the good folks at AVS for squeezing me in last minute on the pre-order special.

 

I look forward to learning a lot about this unit and sharing my experiences.

So we just got the RS4910 today and it was defective :(

 

HDMI 1 did not work sending a native 4K signal. The projector didn't recognize the input. 1080p worked fine. I noticed that when my cable box was booting up it showed the boot screen in 480p and the projector displayed the image only in the top left quadrant with crackles and bars around it, along with a strobe effect. After the box booted up and sent 1080p, I forced it back to 480p and again the projector showed those artifacts.

 

HDMI 2 nothing works at all. It basically gets no signal no matter what is fed to it. I take the cable which works in HDMI 1, move it to 2 and change the input on the projector and black screen. Normally when I plug/unplug an HDMI cable the sound from my receiver stops a bit while it does the handshake, but plugging and unplugging from the second port doesn't do that. It appears the HDMI chipset on my projector was dead.

 

The picture was great otherwise in 1080, but it's going to have to be sent for an exchange which is unfortunate because I was going to use it for a new years party.

Bummer, sorry to hear about that ziantos.

All these input signal issues, from flakiness to flat out not working, being reported with the new JVCs is not sounding good.

Ouch Ziantos... That is not much fun..

So far I'm very impressed with the 4910. Quite a step up from the RS40, and this is the picture quality I have been searching for. So far I am liking eShift. Much sharper picture than the 40.

Only way I have to send it a 4k signal is to switch my Onkyo 1010 into 4k upscale mode. To do that I would have to disconnect my Raidance Mini and Darblet. Don't feel like doing that right now.

Out of the box color is very good, but I haven't stuck my meter on it yet to really see what is going on.

DI appears to work quite well. The only time I have been able to see it working is on fast fades to black. You'll see the picture fade out and then there is some residual light on the screen.. at that point you can see the DI clamp down.

Perhaps tomorrow evening I'll feel more up to getting the meter out and seeing how it looks out of the box, and how well it calibrates. For now I'm going to swap more discs around and see what new things pop out, that I haven't seen before. biggrin.gif

Yeah same here. That is how I did the 4K test. Just told my onkyo to upscale the picture. I was impressed by the picture quality in 1080p, but it sucks having to do an RMA now. :p

It sure will piss a lot of people off if the much touted new 4K inputs won't work for anyone, even with upscaled 1080p to 4K (which is what I want to do). It's early going, though.

I hope so too. It's difficult to say if it JVC's fault or bad shipping by UPS.

I got my 4910 earlier today and already have 5 hours on it. I haven't attempted to calibrate it yet; I'll probably get around to that next weekend. Bright corners on my copy are slightly worse than they were on my 4810 but the DI helps mitigate that a great deal since they're only really visible on full black screens anyway. Convergence on my unit is better than my 4810 was. I did notice the DI pumping a little bit once credits began to roll, but it never drew attention to itself during the two movies I watched (Pain & Gain and Oblivion). The iris is much quicker to respond than my VPL-VW60's iris was (although that's a 7-year old unit).

One thing that is incredibly annoying is that 4K eshift is automatically engaged when you try to use the projector's built-in focus and convergence patterns...even if eshift is off before you bring the patterns up. Obviously this makes it very tough to dial in the focus using the built-in patterns since you can't see the pixel structure at all when eshift is engaged. If someone could figure out how to shut eshift off when using the built-in patterns I'd appreciate it. Fortunately you can use external patterns to adjust focus so it's not a tremendously big deal.

*EDIT* -- the projector's not engaging eshift per se when displaying the internal focus/convergence patterns, but the overall image is definitely softer than when eshift is turned off. This is easy to see by the text at the top of the screen. For example, when adjusting focus, the word "Focus" in the top right corner of the screen is much sharper when using an external source/pattern (with eshift off) than when using the internal pattern.

Are you sure the iris is fast enough to work? The Mitsubishi hc5 / hc9000d you could leave the iris on too and it would not cause issues... As it was to slow to actually do anything during real content... Is the JVC the same? Easy way to test... Use test patterns go from a 100% white window to 100% black, does the iris work very fast or extremely slow... If super slow like the Mitsubishi hc5, it's not working at all.

Those trying to input 4K... Just throwing this out there... A blu-ray to 4k upscale is still protected correct? Then maybe that's why it would not show a pic.

Sound like it may only work with a pc outputting unprotected 4K files. Like from a home 4K camera.

So don't RMA yet thinking it's not working. Maybe it does, just not with the material you wanted it to work with.

Blurays are HDCP but not the latest HDCP 2.2. The JVC should I believe accept HDMI not however HDCP 2.2. I am just repeating what I think.

I would have thought it would have worked as well, but maybe the 4K input when accepting 4K can't accept any protected version of HDMI. Not sure. I don't have the unit to test.

HDCP is not the problem. I am upscaling my roku which is getting media from my plex server hence no HDCP. Also HDMI input 2 doesn't work with any signal for me, and 480p has artifacts across the board which I notice when I go through the menus of my receiver because it kicks back the resolution to 480 when I do.

It definitely works. During the scene in Oblivion where Jack and Victoria are in the pool, you could definitely see the iris working very quickly (looking at the projector and watching the iris move, not at the screen). It wasn't obvious that the iris was working while actually viewing the picture though.

*EDIT* - When I say "it wasn't obvious that the iris was working," what I mean is that the iris wasn't drawing attention to itself. The picture looked rich and dark, but there was no obvious pumping or other artifacts.

Well that's good. So do you like the picture better then your RS4810, or about the same?
