Well, had my calibration done this last weekend by SOWK and he did a great job. I don't pretend to know everything that he did (even though he explained it all in great detail) but the picture looks 100% better. It was the best money I've spent so far on the HT project. I'll get the details up later after I get a chance to look at the report he sent.

For those that are familiar with both, what might one expect if he were to move from the RS4810 to the RS56 in terms of improvements in the image quality?

Is the higher contrast ratio the main difference? How would this generally be perceived by the viewer? Blacker blacks, more depth to the image overall, both, or other?

I've been considering the possibility of upgrading to this year's new version of the RS56 (57?) and I'm trying to get a sense of what improvements in image quality might be expected with such a move.

Appreciate any feedback.

Does anyone know what the default MPC settings were for enhance, contrast and smoothing in MPC FILM mode?

50/50/50 for each is way too high. Personally I keep the first two at or below 20 and smoothing at 0. If you set it them too high you get tons of ringing and aliasing artifacts. 50/50/50 will give you those artifacts.

I believe so too. Was asking what was the original default setting from JVC as they don't mention that in the manual. I think I read someplace they were 50/50/50 (mid way) but I have always run mine closer to 15.

Picking up a X75 next week.
Plan on using my Spyder3 for calibration once the bulb has 50 hours. The calibration process has the sensor facing the lens for the calibration and then there are two more steps for the environment settings. This seems to take into account ambient light (which in my case will just be the reflection from the screen). There doesn't seem to be anything to account for screen material in the process. Does the Screen Adjustment setting feature work with calibration? Should it be set before or after calibration or just left off as the calibration overrides it anyway?

Mancave: Draper Luma II HC Grey 2:40 128" (Contrast Grey XH800E), Da-lite Model C matte White 16:9 106", Denon 2807, PS3 60GB, OPPO 981HD, Monster Power Pro 3500, DT SuperCubes x2, Wharfedale Diamond 9 series x 7, Infocus SP5700

Folks,

I need the help of anyone with a JVC projector using the RF Emitter. I just noticed in a review of the X75 series that the RF emitter is a module you stick into the back of the projector.
I'm upgrading to this year's RS57 which uses the same chassis and presumably the same RF emitter. My problem is that my projector, out of necessity, is positioned as close as possible
to the back wall, with the HDMI cable literally missing the wall by fractions of an inch. I'm worried that the RF emitter might not fit there.

Could someone please measure the depth of the RF emitter for me, so I can know how far it will stick out from the back of my projector?

Many thanks to anyone who can help.

Rich

Thanks very much!

I just measured. Damn, it's not going to fit. Now I got me a problem I never knew was coming.

My next question for the forum:

What are the real world benefits of the move from IR to RF 3D glasses with the JVCs?

I remember reading somewhere that the new JVCs will still work with IR, but I don't know what advantages I should be aware of about moving to RF instead.
Some people have mentioned IR flooding the room from the JVC IR receiver, I think. But...what's the problem with that?

Does the factory IR wire fit? if so, you can run an extension cable. I just cut up a pair to make the splitter, but a single cable will work.

Now I have to remember where I got this 3 pin extension cable from.

Much obliged. It would be great if I can get a solution for using RF. Is the solution you are proposing one that would have me using RF? Or do you mean I'd just use IR glasses?

I'm trying to figure out exactly what you mean, and what is going on in that picture.

I see the RF emitter attached to one end of the white cable, but what's the larger "JVC" labeled box at the other end, and how would this attach to the projector?

Wait, I might be slowly emerging from my "duh" moment, but..

...if I could just use even a short extension cable that plugs into the back of my JVC then I could place the emitter where it will fit on my projector lift.

Do they make an extension cable that would work from the JVC emitter to the projector input?

Is that what you are suggesting, zombie?

(If so, since I picture only a single cable from emitter to projector, all the other stuff in that photo is throwing me off).

it's just a splitter, so the free end plugs into the back of the JVC and it splits the signal to the RF transmitter and the IR transmitter. A single extension cable would allow a single device to connected to the projector.

If the RF is too big, this cable should work fine assuming you have at least enough room for the connector + a sharp bend of the wire to clear in a specific direction.


Here is a single cable:

md3_f_con.gif

With my splitter, I simply took 2 of these and spliced them together so I could run the IR and the RF at the same time.

Yes, I just googled and found that same item sold at an on-line store.

Thank you Zombie, I'm sure that will work!

I would have had to either unscrew and reposition my projector shelf and also probably undo and re-adjust my anamorphic lens sled as well, to accommodate the standard IR emitter.
But an extension cord like that would solve my problem.

If he can plug in his power cord, he'll have enough room to plug that in and bend the cable. I know because I keep my X55R snug up against the wall on my shelf and use an EStar emitter that uses a long cord to connect the emitter.

Seegs,

I actually replaced my JVC's power cord with one that has a 90 degree angle, to get my projector even closer to the back. I've got bay windows behind the projector, but the back has to be as close as possible to them, but clear the window ledge as the projector lift raises and lowers.

I actually just bought the cord Zombie linked to above, from ebay. Hopefully it won't have too much protrusion. I'm sure it will be better than the original RF emmiter itself. (I hope).

With my splitter, I simply took 2 of these and spliced them together so I could run the IR and the RF at the same time.

In case anyone is in a similar situation to mine, with room behind their JVC at a premium, I figured I'd report:

I bought the very cable linked above from Ebay.

The connector itself is essentially the same size as the IR cable supplied with my RS55, but
this RF cable is a bit thicker and stiffer. I just tried plugging it in to the back of my current RS55 and it just barely clears the wall, so it looks like it will work.
Many thanks to Zombie for suggesting this solution!

Update:

I've had my RS56 for exactly one year now.There's just over 1000 hours on it. It uses a newer bulb than the previous years models where some of the early bulbs had light output issues (bulbs dimming early/bulbs dying early). They supposedly fixed these issues by the third generation of bulbs, but my model uses a completely new bulb as many of you (know. It's one of the reasons I waited a bit to buy an RS56 instead of an RS55).

I run an 8 foot wide 16x9 screen with ~1.1-1.2 gain.

I run the projector in low lamp mode with the iris at -6 (range is 0 to -15 where 0 is open all the way) and have been tracking the light output using a light meter as the bulb ages:

Projector installed early January 2013.

Apr 14/2013 - 424 hours: 10.5 ft/L
July 23/2013 - 646 hours: 10.4 ft/L
Nov 19/2013 - 931 hours: 10.0 ft/L

Note: I'm kicking myself for not taking a bunch of measurements in the first 400 hours as I was curious how it behaved during this time. I did not however notice a massive light drop off in the first ~400 hours. I never felt I needed to adjust the iris during this time. On my next bulb (already purchased) I'll definitely measure it every ~100 hours or so.

At 931 hours I changed the iris from -6 to -5 and light output jumped up to 10.7 ft/L.

This 6.5% change in light output is barely perceivable. I notice it of course as I play with the iris but if someone was to choose one of the two iris settings and ask me which one it was, I could never tell.

I've got 5 more notches of light increase I can get by opening up the iris more before I have to start running in high lamp mode, and I'm fairly confident I'll never have to go there which is great as the projector is quite literally dead silent in low lamp mode. On high (which is used automatically for 3D content) the projector's fan(s) are noticeable. Most people wouldn't care but I wouldn't be able to run it 100% of the time in high lamp mode without some form of hushbox/sound isolation which can get complex (forced venting required to do it properly).

All things said and done, I'm really pleased with this machine. I wouldn't change a thing.

Had my RS56 for over a year now and greatly pleased with it - however yesterday it developed a clicking sound when it is opening or closing the lens cover (when you switch the machine on or off). Sounds like a plastic gear wheel snapping against something.

The lens cover still opens and closes normally so I hope that it will last for a while so I don't have to send the huge beast in for service because of a faulty motorized lens cover!

Anyone else having problems with their lens memory? After a couple weeks my presets all shift about 6" to the right. I'll reset them and they'll be good for awhile but eventually will all shift to the right again.

I've also developed the same noise. Not all the time just randomly.

I wouldn't worry too much about that first 400 hours of light output. On both my X75 and my current X700 I saw both of them either maintain or actually slightly increase their light output in the first 400 hours. The new light engine for the JVC line has been spectacular compared to previous models. VERY stable for light output, gamma and color.

Yep. JVC new lamp design is one of the best lamps in the industry.
