You can call Mike or Mark now to get on a pre order list. They will then call you and let you know the price when they know and give you the option to order or withdraw.

But it does NOT the 'elevate black level' any more than if the JVC had ~ twice the lumen output that it has.    Wouldn't you like the JVC to put out 2000 calibrated lumens, with its same excellent o/f CR?    That is what the HP screen effectively provides.     OF COURSE the black level is increased, as is the white level, but the o/f CR is unaffected.   There is no 'poison' to pick from here.    I think EVERYONE would choose to have a JVC with twice its output of calibrated lumens and its same excellent CR.  

(BTW, though I had a RS1 and RS20, and liked them very much, I don't have one now.)

I agree with everything you have written, and you are right, it would take a great deal of money on a projector to reach this combo (JVC/HP) of brightness. However, I have a high gain Mocomtech 20 gain screen and a bat cave. The blacks are fantastic with the RE45, but, you can see the dark grey bars top and bottom on a scope movie. Not so when I put a unity gain screen up.
Sorry I have taken this thread off topic.

Off topic, but how do you like the 20 gain screen? Does it get near that? And do you have to mount it above your head like a HP screen? I was looking into thoses screens earlier but they can only ship me the 7 gain sample.

No problem, Gary; I took the bait!    I've just been so pleased with my HP screens (initially the old 2.8, and now a 2.4 since I wanted to go larger!), and having as large a screen as I wanted would not have been feasible without the HP.  My original HP2.8 was a 110x62 (16x9) screen with a JVC RS20, but I like it so much I wanted to go bigger, to take advantage of all the wall space available.    So my present HP2.4 is 144x72, giving me 144x61 for 2.35 pics, and 136x72 for 17x9 (with my present Sony 1000ES pj).

 

Even though the Sony1000 is much brighter than my previous RS20, with this size screen I very much appreciate the HP screen.   I do like the 'giant plasma' look.

It's nothing special, simply a former master BR (17.5x14x8.3H) that became a teenager den when we added a second story, and with my two daughter now married (each having produced 2 grandchildren!) and out of the house, I inherited it as 'my' room.   My wife made heavy dark drapes to cover up windows, so no external light, and I've added ProtoStar material on the ceiling out ~8 ft from the screen wall, and black velvet on the screen and side walls.    So by now, though not a true 'bat cave', it's pretty close.    I sit ~ 11 ft from the screen, so ~ 1.0 SW (144W for 2.35, 136W for 17x9); I do like the 'big screen' pic!

 

My wife of 45 yrs passed away (too young) about 1.5 yrs ago, so now it's mainly just me, with friends over occasionally.    It's a great source of pleasure.

Does not have to be anything special.Everyones system can be great. It does not have to be a 100k theater room most of us do not have the money for that. Very sorry hearing about your wife. My ex mother passed away at the age of 39 indead way to young.

If you get a chance though would love to see the setup still.

I really don't know how to measure the gain, but it looks brighter than my pioneer elite plasma.
On bright white scenes you can see the screen texture and this bothers me. My family loves it. The screen material looks flat up close.

Miller, I'm sorry for your loss. 45 years together is a rarity.

Thanks, I assumed it would have some type of texture that is visible.

You are absolutely correct in one matter however: The difference in use is not going to what most people would consider substantial even though one unit has nearly double the contrast ratio on paper. Many people do not realize this. 90,000:1 for all intensive purposes will not look nearly "twice as good" as 50,000:1.
Kal

The RS56/X75 gets most if not all its extra contrast from the use of a second iris in front of the lamp, unfortunately when closed down this second iris reduces the projectors light output roughly in proportion to the gain in CR.
So, unless you can live with less brightness than the base model JVC provides with the lens iris closed down to minimum the RS56/X75 cant provide noticeably better CR.

In effect the 90,000:1 CR spec of the RS56/X75 is not achievable or useful unless the screen is small or very high gain because the picture will normally be too dim with both iris closed. Only the top model RS65/X95 offer a real advantage in CR due to hand picked components, but even then its only a modest improvement and no where near as significant as going from a base model JVC to an LCD projector for example.

Does anyone know, if it possible to extend the cable for the JVC emitters? I can see the new RF emitter is small, but plugs directly into the rear end of the X models - but this could be a problem when shelf mounted when/if space on the shelf is already tight.

I'm using 25 feet extension for the IR emitter in my X3 to move the emitter to the top of the screen facing the viewers. Since the JVC IR and emitters are interchangeable for all 3D compatible DLA projectors I see no issue with using extension cable with RF emitter.

What type of cable is it? Bought or MacGyver stuff? :-D

- when I look at the rear end of the X30 - it looks a bit like an old PS/2 plug....

I would naturally have soldered the cable myself but I could not find my jumper cables and was out of coins at the time so I bought a cable online tongue.gif

Here's the JVC info on the connector, it is 3 pin mini-din.

Hmm... I just read somethign about the Monster RF glasses - is this a VESA port on the JVC ???

Click on the 2nd link in my signature, I made a splitter cable last year for the JVC emitter + Monster RF setup.

The company I bought the cables from (listed in my link) is closed until Sept 29th. It's just a 3 pin VESA connector, the adapters are all over the internet and could be wired with a 3 wire setup from Radio Shack, etc.

Just ordered my 4810 - hope the "tweaks" make my first projector ownership hassle free and with a beautiful picture - now I just need to get the theater done but I now have inspiration!

Some good pricing on the JVC RS4810's...

I have one on order, and will probably keep it for at least a year... Lol.

I don't usually keep projectors longer then 2 months or so.

Why the 4810 over the RS56?

Reasons why for me...

~$1500.00 difference
RS4810 should be brighter (remember I have a 150" wide 2.35:1 scope - 1.0 gain screen)
Extra QC... Not sure it means anything.

What I will miss...

1/16 convergence adjustments
Knowing I don't have a RS56... Lol.
THX mode
Any extra contrast advantages.

understood, that makes sense. I can clamp down the iris almost all the way on the HP screen and it's still fairly bright, so I'll give the RS56 a shot since I think the 55 looks great with my setup.

Actually I don't think you'll lose out much at all SOWK:

1/16 convergence is a scaling device, not a true pixel shift, so may even lose resolution.
Knowing you don't have an RS56 (can you see the badge in the dark? wink.gif)
Not sure the THX mode amounts to much, when with proper calibration equipment you should be able to achieve probably better results than an out of the box preset. Alternatively with a Lumagen VP for much less than the price difference you'd get much better results than the THX mode for sure.
With such a large screen and low gain you'll have the iris pretty well open I imagine, thus wasting most of the RS56's extra contrast as you won't be able to use the second iris and therefore won't gain the extra contrast.

Hope that makes you feel better. smile.gif

I know. smile.gif but it just nice to have features even if I never use... Lol.

I have been a calibrator for many years, and never used THX mode anyhow.

Also the pixel shift with the RS50 was horrible, any shifts caused major loss of resolution, on the rs55 they fixed it. I was amazed I could not see a loss of resolution even with the 1/16 Adujustments when I tried it.

How far away do you have your projector setup in your current setup and planned for the 4810?

I'm not following...The RS50 did not have 1/16 pixel shifts...it only had the capability to shift by 1 pixel increments. In many cases this wasn't useful tho....
