Sure it does, but in a minor entity .
Obviously, a bat cave it's better anyway to catch the best performance results, but even in a living installation you'll be able to see a lower black between a 50.000:1 and a 70.000:1 CR machine !
I can tell it for sure having test it under my skin !
Plus, repeat, with a 70.000:1 machine you're able to run a higher gamma without crushing the blacks

Hey Thrang,
Good to know that I was not being overzealous with my initial review of the RS40 regarding 3D

As far as 2D, I was coming from a medicore 2D experience with the RS20 where Sports were nearly unwatchable, so the RS40 is infinitly better in my opinon, but again I did not own the Sony VW85 so as they say ignorance is bliss.

And based on the banter in my comparison thread, knowledge is a curse!

What I find amusing is the selective dispute with what I reported. If there was something negative with the Sony, I obviously had a completely s**t-upon, dysfunctional unit. If I reported something subpar with the JVC, it was accepted as-is, and no-one raised the possibility that the JVC might be "broken"!

And the magic dual iris that nobody knows what it achieves (JVC say it supposedly helps the purity of black whatever that means). Plus the Xenon bulb simulation with step-in filter, more preset profiles that are not just gimmicks, screen compensation for material types, light/dark gamma tweaks and film tone adjustment.

so the 50 has presets for what type of screen material you have and the 40 does not? I have a daLite cinima vision fabric 1.3 gain. What setting would I use on the 50?

If you are planning to get your set calibrated (or are calibrating it yourself) then you don't need this feature at all. In fact when I calibrate it I'll have that feature off, then adjust for color shift depending on what the meter tells me. Nothing special needed during calibration assuming you are calibrating off the screen or from a trained meter off the screen (which I do).

I have also darkened everything I can between the lens and the screen, black sheets for the recliners, covered the light wood on my klipschorns with a nice black fabric, and moved the movie shelves behind the projector since there are so many white spine balens to the movies. So everything is pretty dark and the room is a finished basement with windows completely covered. I should have mine by Wednesday at the latest.

I hate to be the barer of bad news, but, according to the JVC owners manual, you have to be at least 14.86 feet away to project a 150" diagonal image. At 14.86 feet away, you are at the extreme widest zoom setting.

thrang:

So, in your opinion, a shelf mounted RS50 would be bright in 3D mode, in a true batcave, with my 159" 2.8 HP.....right???

I'm concerned that with aging (say 150-300 hours), the lamp wouldn't be bright enough on my 159" screen.

BTW:
How is it possible for the new Audi A8 (I want!!!) to have LED headlights, and not have LEDs bright enough for an 8K 3D projector, such as the RS50???

Is it due to the white light of the headlights vs the need for red, green and blue light in a projector???

Maybe next year???

Thats tough to say - I don't know what the math is, but 159" screen is quite a bit larger..

I would not classify my 3D as bright in Normal mode, let me be sure I am being clear. It is more than adequate for what I've watched so far, and "brighter" than the 90es...

I'm guessing you will definitely be in High lamp mode with that size screen.

It's been a while since I used a JVC in terms of bulb aging issues, and I don't know if the new line is any different.

Of course, your true bat cave will help.

I'm thinking you'll be ok, but I suspect you will not describe it as bright...

wow, I thought my 142" Cinema Contour 2.8 HP was pretty big. I am also in a batcave and my current 3D projector (Acer 3D DLP) puts out about 700 lumens in 3D mode. It's 'just right' on my screen and I am pleased with the brightness through my glasses.

I am hoping the 40 or 50 will provide the same experience.

This is not bad news....I have it on a dresser behind the seating area, but it is not against a wall. I can easily go 14.86 feet away, so it's good news actually to know the exact measurement. All I need to do is move the projector back on the dresser (the 14 feet is wqith the projector on the front part of the dresser but I can move the dresser back if I need to), my lens is directly in front of the screen in the middle.

My projector/emitter and glasses arrive tomorrow (Wednesday). I am very psyched!!!!! Bye bye Epson 1080, it's time to find a home somewhere on Ebay for you.

Don't forget the minimum distance to the back wall that JVC has listed. This is to allow for air flow. I don't have the spec here, but it is in the master thread. It wasn't too much.

I thought the latest info from the manual/Gary was that there wasn't ANY clearance required vis a vis the rear wall (other than a few inches to accommodate cabling, etc.) given that the 'rear' intakes are actually 45 degree/diagonal intakes, and draw as much air from the sides as they do the rear.

After looking at the online owner's manual, I think you're right. There are clearances listed for the top, bottom, front and sides but not the back.

JVC asks for 8 inches. The X3/X5/X7 owners manual I have shows a diagram asking for 300 mm or more on the sides, 150 mm or more above the PJ and 200 mm or more behind the projector. 200 mm = just under 8 inches. The way I read the owners manual, they show the need for 200 mm behind the projector, although it's hard to tell whether or not it is showing the front or back, but it would make more sense that the front of the projector is automatically free from any obstruction since the lens is there.

It's up to you exactly how close you go. For instance, I may go slightly closer but there will be no obstructions above or below or to the sides. I may put a vent in the wall and use a fan to increase air pressure back there where the inlets are.

Won't be seeing one from me unfortunately. Shane is going to be reviewing the RS50 shortly for the magazine and I look forward to seeing what he thinks. I'll be around while he's working on it, we live about 30 minutes from each other. I am going to buy one here soon and will post my findings/impressions afterward, but that won't be until after the New Year most likely. My holidays are pretty crazy with travel and family.

Hopefully we'll see some comments from Greg, I always enjoy his great reviews!!

DaLite have a normal and high contrast version of the cinema vision fabric. These correspond to screen compensation modes 14 and 15 respectively.

I agree. The only clearance you would need is for the cables! They are both intakes on the back, and as you said, at 45 degrees. What possible need could there be for free airspace at the back?

I disagree. The front is where the projector exhausts the hot air, and if you're placing it in a hushbox, or similarly confined space (e.g. a dedicated projection booth), you need to allow for enough space ahead of the entire projector (as opposed to just the lens barrel, which obviously needs an unobstructed light path to the screen). If you don;t allow for that space, there's the real danger the hot exhaust air will circulate in the vicinity of the unit and reenter it via the (cool) air intakes.

Just finished my first RS50. Appeared to have better ANSI than previous year. Motion was much better than last year. Colors work differently. Light output similar to RS25. Sharp image. Still has anti-alias filter. Good looking unit.

See how much light is left if you try to focus it on a .6 in. display chip.

Great! I will be looking forward to hearing impressions from the three of you, especially in comparing the RS50 to the RS35. Since I have no interest in 3D at this time, I am very curious to find out how the 2D performance compares - it is *really* better than the RS35, or are the differences mostly on paper?

Thanks!

To me it looks like they are showing you how far away from a back wall you need to be. It looks to me like the diagram is showing that the front where the lens, light and exhaust is should be totally and completely free of anything what-so-ever. I guess we'd need verification.

Anybody talk to JVC about this?
post #117 of 4215
IIRC, Gary_B ended up stating there was no spec for rear clearance. The diagram below (from the owners manual) does not show any required spacing behind the unit.

It comes up a lot and really isn't a hard concept to grasp. I know you get it Highlander. In full on/off, there isn't enough light reflecting from the screen to reflect back off the walls and onto the screen to raise the black level. This is why light colored walls don't affect on/off CR. With a mixed image, there is more light bouncing off your walls to the screen which is why ANSI CR is affected.

Thanks Jeff. When you say motion, are you referring to the FI modes, motion blur (sample and hold), motion induced contouring, color fringing or all of the above?

Also, how did you find the light output and on/off CR compared to last year?

And finally, when you say the color worked different, was this in a good way, bad way or neither better nor worse?

agree wholeheartedly. I'd really like to know how these compare to the RS35. I've been toying with prospect of upgrading but would really like to wait until a longer lasting light source is implemented or a dramatic 2D PQ improvement is evident.
