And will any level of vertical shift hurt me theoretically (other than reduce horiz shift min-max, which I shouldn't need anyway). ? Thanks
ted, I'm throwing a 110" diagonal 16:9 image from about 12.5 feet with my RS4810. My projector is inverted, ceiling mounted, and the lens is aligned with the top of the screen and I'm using a good bit of lens shift, so for zero lens shift I imagine your lens would have to be aligned with the center of the screen.

That said, my focus is super-sharp from top to botton, edge to edge -- I can easily discern each individual pixel and the pixel borders on the focus grid even in the extreme corners of the screen. I wouldn't worry about using a bit of vertical lens shift if needed, especially given your relatively long throw.

Thanks. Good feedback. Any lower and my viewers on the sofa (2nd row) would risk bumping into it upon standing up (much smaller Samsung 710 in pic). smile.gif The camera angle is misleading; it's not really lined up with the 8 ft wall /sloped ceiling edge...it's lower.



I burned the AVS HD709 disc, have the documents and settings ready, and look forward to getting the pj on Monday.

Having done some research, I've come to the conclusion that the X35 is the one I'm after. My usage is about 70% movies. 20% video games (racing only), and 10% sports.

Before I place my order, I just want to run some things by you guys..

I'll be using a 100" screen and sitting 14.5' from the screen. Where should I be locating the projector in the ceiling? The ceiling height is 7'7". I'd like to mount it upside down as close to the ceiling as I can get away with. I'm 6'4" so I'd prefer not having the chance of smacking my cranium into it every time I get up.

I'm still developing the room so I've got room to play.

Thanks in advance,

With a 100in screen, as long as your not using a hi power screen, the ceiling mount will work just fine for you. Ideally you want the projector mounted as close as you can get to to the screen on the ceiling, the closer, the brighter.

So my RS46 arrived late this afternoon. My first goal was to try and evaluate it in a temporary non-ceiling mounted (sitting on a folding table) setup during my "free" 4 hour lamp life demo period from AVS. Not gonna happen! Why? Well, while the picture looks very good on some BluRays I tried out, I am coming, very quickly, to the understanding that I know very little about setting up a modern digital pj. For example, when I chose 2.3 gamma and -15 Iris( w/ low lamp, standard color) I got a very contrasty picture that looked too much. Then I started playing with gamma and iris settings, and of course one affects the other (nevermind brightness, black level, etc which i didn't touch). I never had this much flexibility with my CRT years ago, or even with my Sammy DLP of late. So I guess I need to go to my calibration BluRays and get re-educated. This will take some time....looks like I'm keeping the pj. smile.gif

Soo...question: with this many contrast/black level adjustments (brightness, black level, contrast, gamma, iris settings) is there a decent primer or JVC-oriented thread on what to begin with (i.e pre-calibrate)? I'm not sure even my BD calibration discs like AVS HD709, Spears and Munsil or DVE HD Basics deals with all these controls.

Thanks...I'm probably over-reacting but..wow, what flexibility.

Edit:
Ceiling install is done. Threw on a silly CBS sitcom, 2 Broke Girls. WOW! The colors, texture, depth and black levels are perfect!!! Amazing really. Very happy RS46 owner, with User 1 set as a -11 iris, black level +1, standard color, gamma of 2.2 (i think).

Today I saw two new x 35 projector and it has the same streaking problem + CA.
one of the left side of the convergence error x 35 was also a 1pixel blue shift. Very poor optics new installation (s).
A big disappointment was new RS46/X35 mind that I sold my x 30
post #427 of 2067
Well, just got my RS46 ordered from AVS. Also sold my RS40 today, so the theater room feels sad and empty, I'll be hitting refresh on that tracking number till it arrives lol.
post #428 of 2067
If anyone is looking for an RS46 in excellent condition, check the classifieds for my listing! It's an awesome projector, but doesn't fit my needs.

For the firmware update that requires sending the PJ back to JVC, does JVC cover shipping costs in either direction? For those who've had theirs updated, how long did the process take to get the update and get your PJ back?
post #430 of 2067
JVC Canada paid for shipping of mine. I sent it across Canada ground late last Thursday and they got it Tuesday morning. They sent me an email Wednesday morning saying they looked at and that it has the current firmware. I had to remind them it was for the 3d switcher update that it was sent in for. Mine developed a start up issue the week before so they are trying to replicate it. If it was just the switcher update it would probably be on it's way back already. Dragon Reborn who started this thread had his back in about a week, but then again he lives in the same province as the depot.

I hope to have mine back by the middle of next week.

Hi Mike, I am abit confuse.
Need your help and experience.
For a 100" diagonal 16:9, what is the minimum throw distance?

The user manual is online: http://pro.jvc.com/prof/attributes/inst_man.jsp?model_id=MDL102177&feature_id=11

There is a table on page 77 that shows a wide variety of screen size options and the min/max distances.

100" diagonal 16:9 at the "wide-end" (min) is 3.01m (9.88 ft) and the "tele-end" (max) is 6.13m (20.11 ft)

I was told we are responsible for shipping cost to JVC.

Here is another JVC throw calculator ( applies to the current line up also ) - http://pro.jvc.com/pro/lens_calc/HTML/jvc_REF.html

JVC Canada took care of my shipping costs, to and from. Total time was about 6 business days to get my projector back.

I was told the same and it made me hesitant to send it in. I've been waiting for others to comment on the difference in their before and after 3d experience.
post #437 of 2067
One reason JVC doesn't want to pay for shipping may be because of their claim that the firmware upgrade makes very little changes to the 3D performance, and is thus not needed. Can anyone who has had the upgrade done comment on pre and post firmware 3D picture quality?
post #438 of 2067
There is a big step up, look at this:
http://www.cinetson.org/phpBB3/projecteurs-f2/jvc-dla-x35-lunettes-test-ligne-page-t36129.html and in EU it is free of charges (Jvc pays for it)
post #439 of 2067
When I was sharing these findings with you I was a jvc fanboy.... My 35 has this firmware from the beginning and I confirm there is almost no ghosting. Day and night from my previous x30 (rs45). The only thing I would like to have are lower noise level when in high mode lamp and more brightness as I really like a very bright image even for 2d. I speak for my 120" 1.1 gain screen. I have ceiling mounted my projector at 3.7 meters to get as more light is possible and I have lens aperture at 0. Others might find my set up really bright. I have a complete black room. Any way the image is very sharp because of the very good lens and the darbee. Black levels are very very good and the colors are almost perfect even without cms.
post #440 of 2067
Once again, yes it does make a large difference on the test patterns linked. HOWEVER, in real life the answer will be IT DEPENDS. If you freeze fram things and use torture tests, yes it makes a difference. If you are watching things in general and not hunting around and fixating on things that ghost, you msay not see much improvemen because you do not see much ghosting now where others who have trained themselves to obsess over ghosting do.

The trade off between the original firmware and post is a noticeable reduction in ghostings for reduced light output. Before the update, the 3D PQ is identical to the previous generations, where light on dark ghosting is obvious.. no need to freeze frame the image on tough scenes. It's been well discussed for the last 2 years.

The RS46 before the update was over 900 lumens in 3D. The RS4810 shipping firmware is ~600 lumens in 3D, same throw, all other settings the same.

The dark on light ghosting on the 2 previous generations manifests itself as the color tint you see in the first shot. This can become very distracting in 3D content - again, not just in still shots. The change in the firmware reduces this color shading by quite a bit as can be seen in ther 2nd screen shot. This change also caused a reduction in light output.

RS46 - prefirmware & identical to the RS40, RS45 as well

RS4810 - shipping firmware

The crosstalk has been reduced as well as light output and a bit of detail/sharpness in the background. The MPC settings in 3D mode on the 4810 can help restore some of the sharpness.

Has anyone tested what the latest firmware does for 3d on last years models x30,x70,x90?
post #443 of 2067
Thank for the info. Two things are still not clear to me:
1) Above compares pre firmware RS46 to a RS4810. So that assumes the post firmware RS46 = RS4810 (at least for 3D). Probably a reasonable assumption, but has it been confirmed?
2) Is the post firmware improvement just because the light output is reduced (900 to 600 lumens)? If so, if we reduces brightness in 3D, will ghosting reduce? (No doubt the solution can't be that simple!).
Were these tests done with the JVC glasses?

This is what I am asking for over a month now and some in here believes that I promote JVC!!!

I haven't seen a post firmware RS46, so i'm not sure if it's the same as the 4810 after the update.

The CT controls with the 4810 make a noticeable change in light output going from 0 to 8. This setting has little effect on the pre-firmware RS46. It should be easy to try after the update to see if it's the same.

It's not the reduced light output, there is a shift in other elements of the image which helps to reduce crosstalk which are illustrated in the photos.

The glasses were the Xpand 104 and Xpand 103 (original JVC IR glasses).

You have a PM;)
post #447 of 2067
I'll look forward to someone posting their impressions after they have their R46 firmware upgraded. Same machine, same room ............
Of course, if JVC would provide some specific information about exactly what the upgrade does (or if there is a work-around), that would help us decide if it's worth sending it in. Saying it's minimal change is not informative. Also, why they are taking a different approach (regarding shipping cost) in the US vs Canada and the EU is a mystery. It all comes down to customer service -- provide clear information to customers and, if there's a problem, take responsibility and fix it.

Did you get the PM I sent you yesterday? Is it still for sale?

post #449 of 2067
I've sent yesterday my jvc rs46 ti Milan for firmware upgrade!!
post #450 of 2067
Can someone please tell me the difference between JVC RS46 and JVC RS46U? I feel like it is a dumb question but I can't find anywhere that says if there is really a difference between the two or not.

Thanks in advance.
