Official JVC RS55/X70 owners thread. - Page 9

Thanks! If I plan to do zoom, I will really be at the close end of the shortest throw. 120 x 1.4 = 168.. I need to measure and do some calculation based on the RS55 dimension, but I think I am like 174... Yike... Maybe I should go with the 115" screen just to be safe.

Another question I have is, with such a short throw, my contrast is likely not going to be optimal.. (although I may be able to close down my IRIS more given the short throw). Do you guys still feel like I will be able to benefit from the increase contrast, say compared to RS45?? RS45 is much cheaper, and with my setup, if I am not going to be able to take advantage of RS55.. then I might save my $$ and put it in other places (like maybe an A-lens...)Oh.. and I have light color ceiling

with AVS being so user friendly will they let me buy both a sony and a jvc and try them out and send back the one I dont like?

Good luck with that....

I think a lot of us would like in on that.....

You can buy them both, and re-sell the one you like less on ebay or something.

Yeah, I really wanted to upgrade my RS40 to a RS55 this year but decided to wait till next year's model since my RS40 has had no problems and throws a great picture but if Nostradamus and the Mayans are correct and the world does come to an end on 12-21-2012 then I know the delivery date on my 2012 new JVC projector will be 12-22-2012....doh!!!

Hi all - new member to the forums but really loving all the great info to be found. I'm trying to decide between an RS45 and an RS55. Seems like the consensus for the previous generation models was to get an RS40 with a Lumagen Radiance Mini vs. an RS50. I realize this is all speculation at this point, but how do you think an RS45 combined with a Lumagen would compare to an RS55? With the RS45 + Lumagen combo, I'd get a slightly brighter picture but would miss out on eshift? Any other advantages that an RS55 would give me?

If I can get a comparable picture with the RS45 + Lumagen, I might go that route. I'd be able to upgrade projectors in a couple of years but I'd still have the Lumagen to get an improved picture.

Anyone have an opinion on which option would be better? Thanks in advance for all the help.

You basically will have to wait to here reports on the eshift.

Manual has been released.

Has anyone with calibration software and sensor attempted to find out if the serious issues with last year's CMS have been reduced or eliminated. I heard from JVC tech rep at CEDIA that the short screen blanking after each adjustment is still there, but this was more of an annoyance while some of the other issues with last year's models were more serious.

Great update thanks but I hope I wasn't one of the "people" you were talkin' about w/ my viewing of the VW95 (cause if you reread it I was talking about comparing it to my RS50!).

The RS55 really sounds like a winner so far!!

Has anyone else received one yet?

I thought we got 4 hours to try out ?

Production models have not shipped yet.

The 50's were delayed because of the needed firmware update. I expect they will be right behind the 45's, so not much longer now.

For Conan, try setting the crosstalk cancel for white to -8. It is just like the Sony, where you can alter the timing at the expense of brightness. -8 will you give the dimmest image but least crosstalk. Also, the X70 produces more contrast in 3D (not related to the panels, but the processing). Try reducing the contrast and you will soften the hard edges a bit and end up with ghosting that may not better than the X7 but very similar looking.

I have my X70R...it just arrived. So production models have shipped in the UK.

Do give me a couple of days before I give a full report. It needs to go up on the ceiling tomorrow.

Doesn't the 55 allow firmware updates directly from the Internet? SJ

Awesome Jonathan... Yippeee!!

Geof and I just FedEx's you a pound of the strongest coffee available... now GET GOING MATE!! Brilliant!!







As far as I've read it does but I think Geof speculated earlier that this one might be engineering firmware (not user firmware), which can't be user flashed.

Congrats! I'll be very interested to see how the 70 compares to your 7...

Yeah, but it could be any number of things. Maybe they have to flip a switch (inside the pj) or something, or maybe they just want to ensure it's been updated because it was never intended it to be used by customers.

Hehe..thanks Kevin and Geoff

It is really too hard to evaluate until its mounted correctly. I did power it up sitting on its cardboard box against the screen just to make sure that it all powered up and worked okay. I did a quick lumens check

X7 currently 1080 lumens (still holding up well)
X70 currently 1250 lumens!

Of course its a new bulb, but we never got numbers like that with the X7 bulbs. The bulb in the X70 is a new version that is backwards compatible with the previous models.

Out of the box the X70 is definitely more saturated, even in THX mode, so it is going to make comparisons a little challenging. Contrast is also definitely up. The thing is because the bulb is brighter, I close the aperture more to match the black levels (-15 vs -9), but with the dual aperture that means the contrast shoots up..also making comparisons difficult. I will try and review/compare as sensibly as I can, but the brighter bulb is going to give an immediate bias towards the X70.

The e-shift is fascinating as if you stand close up to the screen and enable it the pixels boundaries almost entirely disappear. Yet, stand back, and the image looks sharper. If you recall in previous discussions about DLP vs DILA, sharpness perception was supposedly down to the sharper edge of pixel boundaries. But this totally changes that viewpoint as you can't see any pixel boundaries whatsoever, yet end up with a sharper image!

The micro adjustments on the convergence are very interesting and it will take effort to set-up. When you change individual areas of the screen (which are very small as you can do tiny bits towards the edges), it seems to move the convergence at an angle rather than horizontally or vertically across the boundary of the selected area. This gives more flexibility for convergence that gradually changes from one side of the screen to the other, but it makes it an interesting puzzle to get it all set right.

I am curious how you are making these comparisons. Were you able to do a side by side A/B test between the VW90 and the RS55? Or is this from memory? If you had them side by side, can you elaborate on how you did your testing? I just went through this for a RS20 versus VW95 comparison and am curious what technique you used.

conan48 - do you have a light meter? I am curious how many lumens you are getting. Anyone with a unit measure this yet and if so, at what throw and lamp mode?

I provided this 2 posts up from yours. Shortest throw...high bulb

Jon - Hi, thanks for posting your impressions so far. How big is your screen and how far is the projector from the screen? isn't this going to affect the lumen reading? I am at shortest throw for my 142" HP which is about 14 feet from the screen and even with the new lamp on the 50, I measure maybe 575 lumens.

i'm looking forward to your evaluation of the CMS/Gamma adjustments to see if they finally fixed this.

btw, is Manni also picking up the X70 as well or does he still have the X7?

Thanks. And that is at D65? Did you measure this with a handheld light meter or a meter used for calibration? That is an insane amount of lumens for a pj in this price glass with this type of contrast!

Did you measure with low lamp mode and/or at long and mid throw?

The distance from the screen will affect Lux but it will not affect Lumens. You are measuring with the light meter facing the projector (its back against the screen), not reading off the screen right? I am also reading the absolute max the projector will output, not D65.


With the colour clearly being more saturated on the Standard preset this time, I think the CMS will just work very easily (I hope so!!). But of course there is the whole gamma set-up to check/work on.

I don't know if Manni plans to get an X70...he hasn't said anything to me!

Ah sorry...no, this is a max reading that the projector will output. Not at D65. Sorry I should have made that clear.

I'm a little confused here...Are you sure it's a new version (what is new)? Can you look at the numbers on the lamp itself? The numbers from Conan's lamp indicate it's the QLL0194-002 version which has been around awhile (the original was QLL0194-001).

Regarding eshift - can you see a PQ difference with it on/off at >1SW?

How's the convergence compare to your 50 (I know you weren't enthralled with your 50s' convergence).

I haven't opened it up. I was just told that it was a new version.

For e-shift, yes I can definitely see a PQ difference at >1SW. You can adjust how much the e-shift effect is visible, it has setting levels of 0,1,2,3

Convergence is better than my X7, but not perfect. It still does change a bit as it warms up. The centre is very good. Blue heads out a bit in one corner horizontally. Nothing outrageous. My initial tests suggests no obvious motion artifacts or side effects from using the micro zone adjustments on convergence. My X7 moved quite a bit more during warm-up in the centre and it was red that moved. Once warmed up the X7 was okay though...I just didn't like the warm-up effect and red was never as good as this X70.

Thanks for the clarification. Any chance you can measure at D65? Would be great to get a number in low lamp as well. And at different throw ranges if it's not too much trouble. Thanks.
