138" diagonal will probably cost you a fortune in either of those screens I'm guessing, I think HP Da-Lite has to custom cut it for that size. For 138", I would not do 1.4 gain (15fL in low lamp on new lamp with aperture open), but I know some would and it would be generally fine, but I wouldn't since I always want tons of spare brightness in low lamp mode and max contrast with the aperture closed.

Thanks Coder for the insight! I planned to get a loan from you my friend. Can you help a brotha out? lol

Yeah ..these particular screens are terribly expensive for sure!
Didn't you have a place to purchase the Hi power material from?

On another note, have any of the owners used their JVCs with the Black Diamond and Hi-power screens? If you have, which would you choose for all around use? I know of a dealer that gives stellar deals on either. Just not sure of which one to go with. I think I'm going to go for the 2:40 or 2:35 look.

I have a 120" 16:9 now. I would like to have an image nearly as large. I know it won't be as tall, but longer. I want to keep a nice bright image in low lamp mode, using the zoom method. I'll probably purchase in a month or so..just can't seem to decide.

If you went with a 138" diagonal. Would you go with a Hi-power or Black Diamond 2.7 gain? Or a Black Diamond 1.4 running the projector in high lamp?

Give us a call if we can help you.

Agreed! NO WAY I could go back to a manual lens doing the zoom method which means the Sony is out. I LOVE being able to stick my nose to the screen and get focus dead on with a motorized focus control since I refocus quite a bit zooming in out between aspect ratios. Not to mention the 1.6 zoom which wont work in my setup and not being able to use the manual iris without disabling the DI are all deal killers on the 30/95 and the JVC is still the obvious choice for my needs. Otherwise, I would have given it a shot this year since 3d by all reports is better, FI in 3d, better motion, MUCH less gaming lag, etc.........

The lens memory is certainly not perfect on the JVC (in my setup at least) as I almost always have to tweak the lens shift and then sometimes the focus, but it is still better then doing it totally manually like I was doing on the 40. The zoom is dead on every time which is the biggie IMO.

Got sucked into Skyrim last night for the first time and that was dangerous! This game looked gorgeous on the 45 with the iris clamped all the way down maxing out contrast. Dark scenes, bright scenes, they all looked so awesome!

You can probably do slightly better at one of those Pay-Shark Loan Places...

A friend of mine who is even older than me got me into Skyrim. It's neat to explore the world and stuff, but I left most of my gaming days back in my 20's because they get too tedious these days, but they are much more visually pleasing now than before, and it's fun on occasion.

Dirt 2 or Dirt 3 was fun on a PC on a projector (driving game) a bit to me. Tried some Pure and a few other games, not on the JVC but on other projectors. The X3: Terran Conflict game is still one I haven't had a chance to play on the JVC (and I will), it is pure black scenes, it is a space simulation game with exceptional graphics, but is older and there might be some better games out now with space stuff (will need to look).

You will probably find that it is cheaper to buy a manual pull down model B with HP fabric and just cut the fabric out. Many have done that.

Oh wow, thanks Mike. I didn't think of that! Well that is why you're my go too guy! You know your stuff dude!

I am going to go with an acoustically transparent screen (Seymour XD), with a 1.1 gain. Looking at about 133" diagonal 2.35:1... Is that going to have enough "punch" for a fully light controlled room?

I haven't ordered it yet, but really like the DIY material price of it and I know it is good otherwise...
post #2261 of 4435
12 fL to 13 fL in Low Lamp (Aperture Open)
16 fL to 17 fL in High Lamp (Aperture Open)

I've been meaning to add more accurate aperture closed numbers to my calculator, but I need to re-measure it, will do soon.

I am a very casual gamer in general and really only get into it in the winter when work is slow (landscape), but its funny you mention Pure since that game is the ATV version of SSX which is one series I love! There is a new SSX coming out end of Feb that looks incredible if you ever loved the previous games (mainly Tricky and SSX 3 since the new version is mostly inspired by those 2), or similar type games like Pure. Check out some recently released gameplay footage here....

I cant wait to see how good that night riding looks with the extreme color highlights on the RS45!

As far as Skyrim, we will see how long it holds my interest. Like you, as I get older my game playing becomes less and less for whatever reason and games hold my interest for less time it seems as well. I got sucked in for ~5 hours or so last night though which I have not done in years!

I think he needs their flagship Cinema Contour frame with the 3" bevel.

I like the velvet they use on these frames. I bought a ton of it from Dalite, it has an adhesive backing and is easy to cut. I'm looking to make removeable masks for the scope movies.

Skyrim is fun but it gets repetitive after a bit, go visit the temple on the tallest mountain to learn some new tricks. Get some alchemy skill, use enchant and blacksmith to improve the weapons, steal all the soul gems in the college of Winterhold, grab the blessing of Talos, then you'll basically be invincible for a little while.

Could this post be anymore off-topic, I don't think so...

Is that the Pro trim or standard frame style?

Thanks for the tips! I was not sure what the hell to do last night! I mainly stuck to the main quest and am up to the part where I have to go visit the Grey Beards (?). Looking forward to getting back to it maybe tom........tonight is out being New Years.

Sorry for the OT posts though everyone..........

wondering if a 45..maybe i will go for the 55 will be brite enough on my 133'' screen research .95 gain screen?? the room is a 24x22' batcave..

presently using a infocus 7210 which is 4years old, with a total of 920hrs on it.. the pj is mostly used for watching live sports , and a movie/tv every once in a while..

was leaning towards the infocus 8602 as most reviews are positive...but the 8602 has already been out for 2+years, so its like buying a left-over 2year old 'new' car... while it mite be new the tech. is still 2 years old, and as we know time does not stand still...

Same goes for the lens/optical.

So the best you can do is focus after at least 30 mins warm up and look/adjust your convergence then. It might look a little less focused and converged on start up, but most of your movie watching will be after it warms up.

Also, the amount of 'drift' varies between PJ brands/models/tech.

There might even be a break-in period. After materials expand/contract many many times, it might settle into a narrower range of expansion/contraction. Or perhaps might get worse (larger range).

Unfortunately JVCs most recent chassis (this year and last years models) appear to show more temperature drift than previous models. Also unfortunately, my X70 worsens as it heats up, rather than the other way around. It worsens in different parts of the screen on warm-up so its not easily correctable either.

Interestingly the optics are best when cool as well, although the difference is very small.

Maybe I should lock my projector in its own AC cabinet.

It will work especially in lamp high, but let me keep re-making the same suggestion I make to others in this situation, the RS-45 + a cheap DLP, you need 2 projectors for that setup and you will still come out as good as just buying the RS-55. Use the RS-45 in movies and the slightly dimmer bright scenes should not be a big issue, use the DLP for everything else.

The Benq w1200 DLP is best for this but it has gaming lag, or Viewsonic Pro8200 if you want to game as well. Viewsonic is safer if you don't care about the black levels and are RBE sensitive, I doubt the RBE would be an issue on the VS for most people, especially in bright scenes (it has the least RBE of every sub $1500 DLP I've seen). The w1200 is sharper with more features, has a slightly better image with better blacks, costs a bit more. Both of them will be plenty bright for your screen.

Some people would say just grab the Sony hw30, problem is it is even a tad less bright than the RS-45, so it won't help for Sports. So in my opinion, you buy the DLP for bright sports, and you use the JVC RS-45 for movies, makes perfect sense.

So what is the lowdown and general consensus with the lamps in the RS45/55/65 projectors?

Are the lamps the same lamps as the sometimes problematic lamps in the RS40/50/60 series of projectors or are they similar to the RS10/20/25/35 series projectors?

Thanks!

No, the lamps are a new revision but nobody has had one long enough yet to know if they really have cured the problematic failures.

Incidentally I managed to measure the contrast on an X30/RS45 today and it measures exactly the same as an X3/RS40. I measured an X30 at 48000:1 with long throw and max closed aperture. This is almost identical to what I got from an X3 last year. I haven't seen both side by side, but I am not measuring any change there.

If there are improvements from the RS40 to the RS45 then either its the ANSI contrast that has changed, or people are comparing an RS40 with drifted gamma against an RS45 with better gamma.

I'm gonna check the lumen output to see whats going on. We tried every gamma setting there was. It looks nothing like the RS45 to my eyes or the other people here that have seen both.
Maybe the lamp is bad or the projector is a lemon? not sure..though.

Yes definitely do some more investigation.

Incidentally my contrast measurements were based on a user preset with 6500K set as the colour temperature. You will find more contrast if you use higher colour temperatures to MAX out the available output. JVC rather crazily specify lumens output as an absolute max in a mode you will never use, but contrast fortunately is based on something nearer D65.

If you are specifically looking for brightness the 45 will be brighter than the 55.

A nod to gaming earlier, been playing uncharted 3 in 3D on my X30 and I have to say....I really like it, I was all ready for rubbishing it, but the extra depth really adds to the whole game.
Only noticed crosstalk on a few scenes (dark figure against light sky).
I hope 3D doesn't disappear, I'm enjoying the extra depth!
post #2277 of 4435
Some games favor the JVC in dark scenes for sure, I slightly prefer Skyrim on the DLP due to smoother motion, but not by a mile.
Luckily in Skyrim you can sleep at night to avoid the dark scenes on a DLP

Actually the dark scenes in Skyrim don't need a ton of Native Contrast because of the way I set it up for the DLP. I will be testing a few even darker games soon.

Up down right left ok.... Or maybe up down left right ok. I forget, but one of those will get you in.

Also check the old posts in this thread. There are two lens resets options and you need to be careful to select the correct one.

BTWisler,

Do i have to readjust the lens to center with the shift controls first, then go into service menu and do a reset to zero? I'm a little confused.
