is 3D that bad or is 3D to young?

3D is still in it's infancy. It's a mixed bag with the RS45. I would look good it ghosting were not such an issue. Dark content against a light colored background shows noticeable ghosting in most cases. Since you have a decent projector now if you want 3D my suggestion to you would be to replace your Panasonic in the next line of projectors (which could be as early as August). I especially recommend this if you plan on keeping your projector for years. I haven't seen your projector but from everything I've read you'd get a brighter calibrated pic and better contrast over your Panasonic but if you use frame interpolation that might be a step down.

I hate the projector bug.......it sucks the life out of you. to rs45 or not rs45....that is the question, but the answer is soooo hard to get.

3D is so new that I didn't even bother to consider it when choosing my RS45. I would take a guess that in 3 to 4 years a $1500 3D projector would have better 3D picture quality then any of the curent $3000 to $4000 projectors.

And since I usually upgrade projectors around that same time frame I felt that if 3D is really here to stay and not a fad I'll buy a really good 3D projector then.

I was thinking the same thing. 3D is cool. Just not at that point to sway me on what projector to buy at the present time. If it is here to stay, they'll have it perfected in the next couple of years. It should be a lot cheaper by then as well.

I can't imagine nor would I want to wear glasses when ever I want to watch a movie, With the RS45 you don't need 3D with such a life like 2d picture. Now if they made projectors that do not require glasses I'd be all over that. I have read in every new projector post somebody complaining about an issue with 3d, its simply just to new for all the bugs to be worked out.

that being said about how young 3D is.......is the rs45 worth upgrading from a panny ae4000 or should i wait....tic toc....should i cop a rs45?

If you have a million bucks on the bank, then yes! Otherwise: Bring your projector to the store and compare. Or ask the dealer if you can take the RS45 home over a week-end (best option).

Only you can determine if it is worth the money. AE4000 is great. X30 is better on most things, but not everything.

Although I haven't been able to do a side by side comparison, my good friend that lives like 2mins from my place has the AE4000 and with both have very close sized screens. I have a Grandview 112" white and he has a Elite 115" white. I have a touch better light control in my theater room. But as far as movie viewing we both feel that my RS45 is a fairly good step up in picture quality for watching movies.

Almost felt like comparing my RS45 to a RS65. Just an overall set up in all areas. If your main use is movies I feel you'd be hard pressed to find a better 2D picture with any other projector for under $5000, maybe even $6000.

IMO it also holds its own for viewing sports too. I had a Superbowl party this year, and just turned the projector up to high lamp mode and opened up the apeture a little and it threw an awesome picture. We had about 20 people and everybody raved about how great the picture was. So far I'm loving my decision to go with the RS45.

I would still say that you should really try to see the projectors in action for yourself though because everybodys opinions are different.

where would you say the WOW factor is to justify the upgrade?

I think Joseph Clark in this thread owns the RS45/40, Epson 6010 and the AE4000 as a back up. He's pretty blunt about the differences, no candy coating.

He's clear about the differences being quite drastic between these two http://www.avsforum.com/avs-vb/showp...postcount=1468

Is the RS45/X30 has enough power to fill a 161" 16:9 screen? If so, What gain would you recommend for a dedicated HT?

The throw distance is very flexible.

If you wanted to go that big I think you'd have to look into an HP screen.

Off the wall question.

Can you use two of these projectors linked together to fill a larger AT screen for 3D?

2D shouldnt be a problem linking two together at all should it?

Could someone give me some examples of how they would need to be setup? Like how far apart would they have to be mounted from 15' throw 10' ceiling and as large a screen as possible 150-175 would be great.

Does Draper makes this kind of screen?

For those who have calibrated your X30/RS45 and seen your calibration report, does anyone of you ended up with an under-saturated green?

I have calibrated mine 3 times, now having about 80 hours on the bulb, all things seem to be spot on except an under-saturated green and cyan, with dE of about 4.

I went to the dealer today to check out another X30. It suffers from color break-up identical to my unit. We compared with a Sony VPL-HW30ES and the difference was obvious. Sony lacks color break-up and has better motion handling (more smooth 24p without FI engaged). But JVC is better on everything else. Too bad it looks a bit like a plasma with phosphor lag, otherwise it would be a killer in every aspect. The dealer thought it was caused by the 120hz panel frequency vs 240hz on Sony and 480hz on Panasonic.

There were four people in the store when we compared and they could all see the color break-up. None thought it was a big issue for most movies, but we watched the ending of Batman - Dark Knight and we all agreed that it was much more relaxed and comfortable on the Sony.

Judging by the demo machines in the store, Sony VPL-VW95 is the cheapest way to go if I want a picture free from color break-up and a quality that can match JVC. And that is $5000. So, I will try to ignore this issue until I can afford a VW95 (or better).

I wouldn't go that big even with an HP screen, you need a different projector (crossover).

Panasonic ar100u or an Epson g5450...

Except the vw95 isn't nearly as bright as the RS-45 with the IRIS closed, so in order to get the blacks of the RS-45, you'll lose a lot of brightness. In an apples (lumens) to apples (lumens) comparison, the JVC's are still a good deal ahead of the Sony's in black levels. Although the Sony's dynamic IRIS helps close the gap a little, some testers have shown that the actual effect of the Sony's IRIS is only half of what the measured result would suggest. For instance, the IRIS appears to be based on a plotting algorithm that is anti-reactive. So if you measure 80,000:1 dynamic on/off on a Sony, the real effect of the black level is probably more like 40,000:1 in a starfield with not a lot of bright whites or planets. That means at best the vw95es is probably the RS-45's black level equivalent only at half the lumens. It could actually be 1/4 of that, I've been saying for years that people are measuring dynamic IRIS's incorrectly, even if you take the dynamic on/off measurement within 2 seconds, that does not equate to how an IRIS affects most scenes since most scenes are not all black. Of course the same thing could be said about measuring Native on/off as well to some degree (but not to the same degree).

However, for most content this difference would be negligible at best and the vw95es should suffice, just don't expect to get the same lumens. Of course the Sony lamps appear to be better, so after 500 hours (if the JVC lamp issue is ongoing), then the Sony may remain brighter. Although I agree the JVC is not perfect with motion, it is not a big concern to me since I don't watch a lot of motion intense stuff most of the time (some action movies, but that's about it). For my uses, I'd buy a JVC RS-55 before I'd buy a Sony vw95es.

Very good info, thanks. I have read the same in some forums. I am actually running my X30 in normal lamp mode with IRIS on -15 and it is still a little bit too bright for my liking. I have a 82" screen in a completely dark room. So, I think the Sony would actually work better in my room.

I guess it is possible to turn off the auto-iris and just close the iris as much as possible on the sony to get the lumens down and the best possible black levels? I am not a big fan of dynamic iris and getting good blacks without that is probably what I like best with my JVC.

Thanks for the response. I'm currently on page 5 of the thread and treading on but have a few questions. Will I be able to use a large AT screen for 2D and 3D since I'm currently limited to a 120-130" with only one RS45 for 2D and even smaller for 3D?

If linking two together will not allow me to have a large AT screen (150-175 cinscope) what would be the best pj under 15k?

Couple hours later

Ok, I think I found my answers about the screens. It looks like I'll loose too many fls if dont go with a silver screen so passive seems out of the question for me unless add a second drop down screen.

Hi! is blacklevel the same between x3,x7,x9,x30,x70 and x90?

I would say no.

They all have different contrast ratios but use the same bulb so they have the same (or very similar) light output.

Contrast ratio is the measure of lowest black to brightest white. If the brightest white cannot change but the contrast ratio goes up with the better projectors, then that means the black level goes lower.

On the higher end models the panels are hand picked to meet certain standards. There was a german review site that explained all this that at the moment I can't seem to find...

Thank you! So if I am choosing between the x70 and the x9 I
am practically choosing between e-shift or higher contrast? I am not so much interested in 3d.

They are both incremental differences, but combined make a somewhat significant difference if you take the opinion of others that went from the RS-40/45 (x3/x30) to RS-55 (x70).
The x70 has e-shift just like the x-90, so it is mainly contrast.

As you go to the RS-65 (x90?), I would think that tiny boost in contrast is not really worth it unless you have money to burn, so the RS-55(x70) should be the stop-gap you should rest on as you'd be better off upgrading later in 3-5 years then buying an RS-65 (x90), unless your rich and just want to spend more money to irk every little bit of contrast out.

Thanks, no the x90 is not what I am thinking of, but the x9 over the x70 if price is the same or lower than x70?

The X70 is going to be noticeably brighter than the X9 and you get the benefit of the e-shift if you sit less than 2 screen width's from your screen. Plus the gamma/grey scale controls have issues with the X7/X9 vs. the newer X70/X90 which are fine.

Since the X9 is that much dimmer than the X70, you would likely need to run with the iris open wider than on the X70, which effectively could give you worse contrast on the higher rated projector.

I am a fan of the e-shift sitting ~ 1.25 SW from a 142" screen. for me, the difference is easy to see with it on vs. off.
