Offical JVC DLA-RS4810 Owners Thread - Page 13

You mean Chromapure not Calman 5 since Calman is Spectracals product.

The Lumagen package is wonderful. I purchased it with Chromapure auto calibration software earlier this year to stretch out my 5 year old BenQ W10,000. Definitely worth it IMO.
It works great and now my new RS4810 will be fully calibrated one hour after UPS delivers it tomorrow--all while I go have a sandwich. WooHoo!

@lyndonlim: It's interesting that the first step in the auto calibration process is to set the brightness and contrast MANUALLY using either the internal test patterns of the Lumagen or a test disk like the one from AVS. Setting these properly makes a real difference in the display quality and it's free--no equipment needed. Just display the flashing bars and adjust the display.

I'm also waiting for my 4810.
I'll be able to share my experience after running it with ST130(2d), HP 2.8(3d), Lumagen 125p calibration and Darbee.

^^^ great setup for 2D and 3D. The 125 point autocal in Chromapure got me interested in the mini 3D which should be here soon.

Sowk, are you using an anamorphic lens in your set up, or do you zoom?

oops... you're right! THIS is what I meant:

CalMAN 5 works very well and I understand ChromaPure's product is at least its equal.

What gamma would you recommend to start; 2.2, BT.1866, or some other?
Like freebits I'm projecting onto a Studiotek 130 1.3 gain. The theater is light-controlled and reflection-controlled.

I like Gamma 2.3 when it's a light controlled room.

Ceiling Mount Question ...

I've received my projector (woo hoo!) and am looking for an appropriate ceiling mount. Sorry for the newb question, but would the following work to mount it to the ceiling with 18" drop?

• Chief CMA-105 4" Ceiling Plate with 1.5" NPT Opening Mfr# CMA105
• Chief CMS-018 18-inch Speed-Connect Fixed Extension Column (Black)
• Chief Custom RPA Projector Mount with SLB-281 Interface Bracket Mfr# RPA281

Many thanks.

Mike

It sounds like the HW50 is a better all around projector but the JVC looks better in 2D??? I only question this because I'm going with a 2 projector setup and will be using the X55 for a 2D only projector for movies. My screen is only 16x9 and not as big as yours but big non the less (153" diagonal). I have up till the 18th to change my mind on the JVC. So the JVC, in your opinion, looks better than the Sony for 2D movies? or is it only better because you sit close to the screen? I sit 15 or so feet back from my 133" wide screen so that would be around 1.3'ish SW back? Would the Sony be your choice for that distance?

For what it's worth, I'm coming from an Epson 8500Ub as my movie only projector which puts out just under 500 Lumens and the X55 has to be around 800? and the HW50 around 900? either one should be a noticeable brightness upgrade. I'm wanting the nicest looking projector for 2D under 5 grand.

Thanks

yeah the lumagen auto calibration package is great value relative to what we could get 5 years ago. who would have thought that you could get a fully automatic calibration and not have to sit in the dark fiddling around for hours to get stellar results. I will check my bank balance then maybe stretch for the package as you have convinced me.

How much does the package run, spiked my interest?

There are 3 options priced for the home user. Spectracal's CalMan is about $3k with a Radiance Mini and a calibrated C6 colorometer. I can't figure out ChromaPure's pricing for their calibrated Display 3 Pro / Lumagen Mini / 125 pt auto-cal offering, or even if they have such an offereing. I gather from the forums that they do. And then there's the Light Illusion system that takes a different tack in that they separate the display profiling from the display calibration. This means you perform a rather lengthy (depending on the matrix size, up to 17x17x17) profiling and then generate calibrations from that data. So, if you wanted to change your gamma, for example, you wouldn't have to go through the whole calibration process again. You just ask the software to calculate a new LUT from the profile data and download it to the LUT box, in this cas a $600 eeColor box. As the lamp ages you would have to generate new profiles, though. But that de-coupling is very intriguing to me. The software is $2650 last I saw, so this solution is competitive if you aren't interested in the Lumagen's many other features. The eeColor box is simply a LUT holder and nothing more. So the total cost of the LI system seems to be $3250 last I saw.

The Chromapure complete package is I think $2279 and it includes a Radiance Mini 3D video processor, which will add a lot more to your system than just the ability to auto calibrate, a copy of chromapure standard, the full deluxe auto calibrate uodate, a calibrated display 3 meter (the calibrated version which is included is called the Display 3 Pro, and an interfce RS232 null modem cable for interfacing with the Lumagen and for installing free software updates for the Lumagen. You will likely need to purchase an USM to RS232 converter to plug into your laptop and hook up to your Lumagen to do calibrations..

Indeed. I have yet to explore all the stuff it does. There's only so much time in the day! And now, with the auto-cal results, all I want to do is watch movies. I'm done with fiddling, for now at least.

Me too: Now I've run the autocal (and had a good look at the results to convince myself ) I'm just watching films on my projector. There's no need and no point to keep fiddling once you know you've got the calibration spot on. I've had my Mini3D for 2 years now so think I know it pretty well, but the autocal just takes it to another level for picture quality and takes a fraction of the time (I can just sit drinking coffee and reading the web while it does it's stuff ).

Thank you, I'll check him out. The cost of the equipment to do it myself seems a bit too steep for me right now. I may buy it down the line but I can't muster a few extra grand right now. I'm buying much more then a projector already for my home theater.

@freebits Thank you. 2.3 it will be. I would imagine that the best way to do this is to set the JVC Custom Gamma to 2.3 and then let the Lumagen tweak it from there.


I'm curious about your screen setup. Do you have a high power pull down screen in front of your ST130? This sounds like an ideal setup as long as the projector is mounted low enough. How large are your screens?

If this is too OT for the thread, I apologize. Seems we're all waiting for Zombie's UPS guy today.

@CintiAudio
you can run the Auto-cal again if the Gamma 2.3 is not your choice. It'll take less than 1 hour even if including the grayscale calibration

Both screens are electric screens but rather small compared to the other folks. They're 106" Stewart and 100" Da-lite. JVC's motorized zoom/focus is convenient for moving between the two different screens.
I've mounted my PJ low enough so that I can enjoy the highest gain from HP screen.

you can search for ISF certfied dealers/calibrators right on their (ISF) website. you can search by State (or province if in Canada)

they also offer training for enthusiasts

i think the following is a good deal. especially if you compare the cost of 1-2-3 calibrations done by a professional to the cost of this bundle:
http://store.spectracal.com/consumer/calman5-bundles/calman-5-enthusiast-with-spectracal-c6.html
or a bit cheaper option
http://store.spectracal.com/consumer/calman5-bundles/calman-5-control-with-i1-display-pro-bundle.html

granted , you don't get the Lumagen
but with CMS now included in the 4810 it will get you very close for a lot less dough.

Hey guys, I was wondering if any of you have had problems with the chief RPAU mount not being able to accommodate the size of the 4810. I can't seem to find the top plate holes that will connect all the arms. it's either the side 2 or the top 2, but it doesn't seem to be big enough to accommodate. Am I missing something?

If you do some research, this was a problem when the present JVC chassis came out several years ago. There are pictures in the AVS threads. You can make it work by having the U plate aligned along the projector width, rather than length but you will still need to drillone hole and slightly enlarge another to make it all fit. It is easy to drill the hole through the metal of the U plate but yoo do need a drill and a bit. You won't hurt a thing by doing it. Or if making a field mod and spoiling the manufactured grid which will aways be hidden when the projector is mounted will drive you crazy and keep you from sleeping, you can just buy the dedicated mounting plate for the JVCs that will attach to the RPA Chief mount. That will set you back over $100 for the plate. Me? I would just drill the needed hole. We installed many that way in our area where the customer already had the RPA U.

Well that's kind of a bummer, I canceled my my 46 preorder because I was told my rpa u mount wouldn't work with the 46. The extra cost was enough to push me towards the Sony 95. I guess I should have searched the forums more for a solution.

While we are on the topic of auto calibration, I am considering purchasing ChromoPure with Auto-Cal as part of a bundle with either the Lumagen Mini3D or DVDO Duo. The Mini3D is a fair bit more expensive than the DVDO Duo, and is very limited as far as inputs/outputs go. I assume that most would position the Mini3D between an AV switcher and a display. If 3D is not a priority (it is not for me), is there any reason to choose the Mini3D over the DVDO Duo? Does the Mini3D allow for a more accurate calibration? Is its video processing/scaling considered superior to the DVDO Duo?

Yes, the Mini3D is superior to the Duo IMHO. It can give you the full 125 point CMS that the Duo can't. Has no ring scaling and excellent deinterlacing. Although it only has 2 physical inputs you can set up 4 'virtual' inputs which can be mapped to either of the two physical inputs so you can optimise your calibration for each of 4 sources even if they come from the same HDMI input cable (ie your amp does the switching further up the line). I do this with my Mini3D (only 3 devices though) and I also split the output so that I can use the different CMS memories (8 in total) to calibrate 2 different TVs and my projector.

I find the support excellent from Luamgen too, with it's own forum where you can post questions, email them config files for them to test out any issues. They once posted an updated firmware to resolve an issue I reported the same evening.
