Official JVC RS40/X3 Owners Thread - Page 176

Hi, I'm looking into getting this projector, and I have a question about the 3D mode. It appears that the projector automatically switches to 8500K by default when put in 3D mode. Is this purely for brightness? i.e, is the 8500K color temp a trade-off for high-brightness required for 3D?

Or, is something else going on, such as the JVC glasses have a warming filter so in order to get 6500K to your eyes the screen has to be 8500K?

If it is a trade-off, have people here re-calibrated the 3D mode to 6500K and is there a general consensus of the results (like not bright enough)?

EDIT: I know my room conditions and screen size will play a big part, but let's assume I'll have the iris stopped down for 2D viewing and wide open for 3D. Is the difference from a iris stopped down 8 steps for 2D and wide open for 3D enough to use 6500K for both, or is 8500K required to get an adequately bright image?

What am i missing? My projector is shelf mounted,when i set it up i could not find anything about ceiling mounting,i called JVC tech support they told me i had to use lense shift,I explained to him he had to be wrong ,so someone higher up was going to call me back never heared from them so that's what i ended up doing.Now i see something about a fix for ceiling mout mode. Could someone tell me where this is in the menu. Would appreciate any help.

What you missed is this thread:

You might start from the end of the thread and work backwards. Plenty of Chief options now.

That is my understanding (but I'm far from an expert). I think it's to compensate for the glasses.

On the "Installation" screen, there should be a line for "Installation Style" with options of "Front" "Ceiling Mount (F)" "Rear" and "Ceiling Mount (R)".

I assume you don't really need to set it to ceiling mount though, since you're shelf mounting, right? I think all it does is flip the horizontal/vertical adjustments (since it would be upside down in ceiling mode).

I can confirm that is exactly what it does. It just flips the image for upside down and front projection.

Shagg,
Thank you for the for the straitforward explanation ,I had it right,didn't know how I got there.Tech support from JVC did tell me there was not anything in the menu. THANKS AGAIN.

My throw is near the short end of the allowable range for my 120" (16 x9) screen at just over of 13 ft. The measurements were done with the iris fully open. This Mode (i.e., Natural with Std. color space) is basically what Chris (JVC USA) reported they are suggesting (except I'm using the high lamp mode while, as I recall, Chris suggested low lamp for 2D). As least for some of the RS40 units the Natural mode combined with Standard color space provides the color points nearest to Rec. 709, so that's an additional reason for selecting this mode for my measurement.

The RS40 has no setting for 'color profile' since (I assume) this is related to CMS which the RS40 does not have. I did go ahead and do a quick measurement for just the screen center location with the color temp bumped up to 8500K (with all other settings the same as I reported above) and the lumens went up to just over 1050. I had also done a quick calibration at just the 10 hour mark on the lamp in Film Mode (std. color space, 6500K, high lamp, custom gamma to get it between 2.2 and 2.3) where I got the color temp to track close to 6500K and low DeltaE at above 30 IRE. I went back and did a quick check for lumens in that mode, again just a quick check at screen center) and it came in at approx. 10% less than what I had reported above for Natural mode (or close to 800 lumens but if I would have used the ANSI 9 measurement points that would have reduced that to perhaps around 750 lumens).

ron, sorry I didn't mean to confuse the terms and wasn't referring to the CMS. I sent my RS40 back over a month ago and don't recall the name for the RS40, but it's the setting where you choose 'natural', '3D', etc. There is an option to turn this off which should provide the maximum lumens the RS40 can provide. Also set the color temp to 8500 as well.

curious to see your results. thanks!

What you are talking about is the "Picture Mode" on the RS40, but there is no OFF setting. On the RS50 there are controls for both "Color Profile" and "Picture Mode" and it is the Color Profile (only found on the RS50/RS60) that has an off setting.

Yes! My projector finally shipped out today which means I should be enjoying 3d next week. I already have my theater room set up with everything I need (except extra glasses - thinking about the MonsterVision glasses). It has been a little pathetic that I bought home theater speakers, screen, PS3, 3d content, and other accessories over a month ago yet only have a 24" monitor to use in the meantime until the projector shows.

And I will be getting it just in time for the new firmware update and my Panasonic DMP-BDT110 Blu-Ray player which arrives Monday.

The only problem I have left is I can't have packages shipped to my apartment so I have to figure out a way to carry this thing home from work on the train.

For those interested, I posted an early set of impressions on the Monster 3D vision vs. Expand 103's over in the 3D tech-talk section.

Thanks for the review on the Monster vision glasses. They looked really interesting to me because they are RF and the lenses themselves look a little bigger.

I have to say that I don't like the fit and size of the JVC glasses. The lenses are just to small vertically. I find myself tilting my head down through the whole movie. They work great, I get no ghosting (so far) and the color and brightness seems to be good.

Does the firmware update reset all settings to factory defaults?

If so, will I get the exact same image as before by plugging in the same numbers I used to calibrate my RS40 prior to the update?

Oh boy! It's a pretty big and fairly heavy box but you should be able to pull it off. Good luck.

Use a cab to get yourself home, you'll thank yourself later in the evening.

Can anyone help me out with a throw calculation on this PJ? Mine will be here Monday, and is scheduled to be installed Tuesday. Unfortunately I still haven't been able to get confirmation from AVS as to whether my ideal mounting location will yield an acceptable throw distance. It looks like my ideal throw distance as far as my mounting options would be about 13' from screen to the front of the PJ.

I have the RS-40 and a 92" WIDE 2.35:1 screen. I am using a Prismasonic HD5000R (the rebadged AVS model).

If someone can confirm that this mounting distance is appropriate for my installation I would really appreciate it!

So without using the anamorphic lens that would be a 69" wide 16 x 9 image (or about 80" diagonal). According to the JVC User's Manual (which you can download from the JVC web site), the throw range for a 80" 16x9 screen is 2.40 to 4.89 meters (94" to 192"). I assume your anamorphic lens simply stretches the image my 33% horizontal for displaying "scope" movies (a typical constant image height setup). So a 13 ft. throw should work.

No, it keeps your settings intact.

Thanks Kris! You helped me save a tree.

It will work but won't be ideal. The throw ratio would be 2.1 and a longer ratio would be better keeping the image coming out of the projector lens as small as possible before it hits the anamorphic lens. Light with such a small screen will not be an issue if anything the image will be REALLY bright. Maybe too much. This installation screams for mounting the projector as close to maximum throw as possible. That would be about 2.79 times the screen width. However, like anything you can make it work at 2.1 throw, just not ideally. Before your installer comes, I would table mount the projector and then try it with the anamorphic at the throw you would like to use. If you need help, call me.

Has the new firmware been released? If so where can I go to download it?

Thanks in a advance.

I just saw it on the JVC.com site. Click on support and then software downloads. Scroll down and u will see it.

When I go to the software updates section of the JVC.com website, the firmware update is version 1.2 which has been out for some time, not the new one that is being discussed in this thread right now.

I probably will have a coworker give me a ride to train station and then call a cab when I get to the city. I just hope my projector and Blu-ray player doesn't come at the same time. My apartment building has a locked gate outside so the delivery guy can't get in and leave it plus I wouldn't want them to just leave it all day while I am at work.

I did find a used/trade-in DVD and Blu-ray store in my area that had a few 3D Blu-rays. I might actually pick some up today, though they are still priced high, but I think slightly cheaper than Amazon.

I am 2-3 weeks from having my theater room ready for it's first use. I'd like to have some usable 3D glasses on-hand at that time. My installer has two pairs of the JVC glasses on order. I was thinking about ordering two pairs of Xpand X103s since they are in-stock, universal, and also a bit cheaper than the JVCs. Is there any additional equipment I need to support the X103s, beyond the JVC emitter for the projector?

From reviewing other posts it sounds like the polarization may be an issue. My screen is a Stewart UM150 which retains a moderate amount of polarization. My hope is to compare the JVCs and X103s and see if one is clearly superior.

No, that is not a new firmware version - it's still v1.2. I am sure we'll see an update from one of the JVC guys once it's available.

Ive been gone awhile. Has the motherload landed yet?

No - that link to download firmware on that page is still for firmware ver. 1.2 from December 2010. Perhaps the new firmware will be posted on Monday.
