Looking at the available choices of 1080p single chip projectors (with anamorphic lens option) on a 2.35CH screen which is at least 10 feet wide appears to present serious issues due to not enough light output/lumens. Whether it's Marantz, Sharp, Optoma, Vidikron, and even the SIM, etc appear to not produce the amount of ft.L truly needed for at least the sized screen as indicated. Am I correct... am I missing one that can?

This would suggest one really needs to look at the 3 chip models for this type of set-up, which presents other issues not to mention the cost (which then leads to 3 chip 720p as an alternative).

I guess with the onslaught of the new JVC projector, this was not a very good time to post new threads like this one. Either that or everyone agrees with me and there ain't much more to say :>)

I'm planning on 122" wide 2.35:1 HP with the RS1, and for me it should be fine (total light control dedicated HT room).

Kodak 333 or Infocus 777 seem to be the "go to" 720p for those that want the light cannon

you forgot panny ax100?

Take a look at my pics, my Marantz can and does light up a 10' screen, my 125" diagonal (10ft) 2.35 highpower screen is really only 100" or so in 16:9 form and before my scope screen I projected on a 110" diagonal highpower screen with absolutely no brightness issues, now if you say that the Marantz or Sim is out of your budget thats another thing entirely but if you can mount the pj appropriately and buy a top lens (im using Isco 3) then I guarantee you will not have a problem when using a highgain screen like highpower or silverstar.

You're possibly not looking at the right machines. Look at the Titan-250 1080p and PD Action model3 for starters. If you are looking to go over 10ft, you wont do it, and retain a good, bright image, cheaply imo.

What about the Optoma HD81LV (large venu) thats going to be arriving soon?
Here is quote from projectorreviews.com in regards to a CES demo this year:

Optoma was demoing the HD81LV in their theater with the BX-AL133 motorized anamorphic lens, in conjunction with a whopping 171" diagonal Cinemascope aspect ratio (2.35:1) screen, and, despite the size, it was still bright inside their fully darkened theater (dark walls, of course).

I'm planning on 122" wide 2.35:1 HP with the RS1, and for me it should be fine (total light control dedicated HT room).

What are you using to go anamorphic on the RS1. Reading the posts on it, it appears the light output on larger sized screens is not quite there. ND you need an outboard scaler to do the "stretch" to make this work. oo many variables being introduced there.

Thanks. Interesting -- that is contrary to what I have heard and read with the Marantz, and I really hate to use a really high gain screen as an artifical alternative to getting the light output required.

......If you are looking to go over 10ft, you wont do it, and retain a good, bright image, cheaply imo.

Totally Agree. Looking in the $20k projector range basically. Would love the SIM 3000 with the add on motorized anamorphic lens, but afraid the light output won't be there on a 10 1/2 ft wide screen.

I've decided to stick with 16:9 for now and go with the JVC RS1. Then when the SIM C5X comes out (their lower priced 1080p three chip DLP), I'll move to 2.35CH and anamorphic. This is a marathon not a race and this seems to make the most sense.

I'm vascillating back & forth between the RS1 & a smaller screen or going with a 777 and using zoom to get a poor man's CH 2.35.

Only trick with the 777 is I would have to come up with an adjustable mount as the 777 standard lens falls short of the required zoom.

Anyone else gone this route?

Youve got to be kidding,how could anyone recommend this pj, anyone who reads all the problems going on over at the Optoma HD1 owners thread and still wants to tangle with any variation of that projector needs to have their heads examined and deserves all else that follows, that pj is a failure and I think a black eye to hometheater projectors, a clear indication of a company that feels it doesnt need to do right by the customer, this one at least to me is a no-brainer :mad:

The 777 is already what at least 2-3 years old? My thought is why invest 10-25k in the full anamorphic set-up and then be depressed in a year when the technology takes a major step forward and the prices take a major step backwards. The C5X should be the answer ! We'll see.

What is a C5X and when can I pre-order one on the AVS?






he he. My rule is never buy a projector sight unseen. I agree with your plans.

I plan on getting the RS1, for a CIH 2.35, at 122" wide Studiotek 1.3 or Ultramatte 1.5, with a Panamorph U380 on motorized sled, which will give a 1.78 for non scope SD/HD, of 92x52". My room is total light control with dark gray walls and carpeting, that width with my throw distance of 17 feet is in the mid range for the throw ratio for the RS1, which should provide 'adequate' footlamberts for that room. From my readings on the CIH posts there would be an increase in brightness when scope lens in place for 2.35, of course a VP is necessary for the vertical stretch, because all of the pixels are being used for the picture which would mostly offset the loss of reflected light due to the increased surface of 2.35.

Big risk in my opinion to achieve at least 15 ft lamberts. Since the RS1 doesnt do the stretch needed for 2.35CH, what scaler are you going to use?

I'm waiting for the Lumagen Radiance, I know the RS1 has the Gennum chip, same or one edition older than the Radiance, but with 5 or 6 hdmi inputs and upgradable firmware, vertical stretch, and various color adjustments that may benefit the limited adjustments on the RS1, I think it would be worth it.
I also feel that if I upgrade to a 3 chip 1080p DLP, that it would still be useful because it is upgradeable and it will be a while until those DLPs get to the 10-15k price range.
joe
P.S. I currently run a G70 on a 87"wide 1.78 ultramatte 1.5 and it now has about 8000 hours on it, so I doubt I get even close to that now, but the picture is still absolutely beautiful with good transfer DVDs and , HD (comcast cable and ota) believe it or not in comparison looks only moderately better, mostly in color gamut and details.

Let us know how it works out!

I agree, except I'm still on a 4805 & chompin' at the bit to pull my seats forward & enjoy a little HD. I don't want to do a color wheel at this point & I figure 720 resolution might be OK for now. Prices have been consistently stepping backwards--The current MSRP of 10k on the 777 is 1/3 what it originally was.

The 777 certainly has the lumens power for zoom 2.35 CH. I just can't decide if I'd be happier going with it or a RS1 & a smaller screen for now.

I'm with you on the C5X--thats what I'm ultimately after too, but I suspect its going to be awhile before its out & at a price point that I'm willing to purchase on.

You waited this long. I think a good interim strategy is to spend the $5k street on the RS1. You'll be blown away having skipped over the whole 720p craze and move your seats up since it will be showtime for sure. Then wait about a year and re-assess. Don't forget the 2.35CH screen is not so cheap either so save up a bit more for the whole Stewart solution. Spending 10k on a Triple 7 solely to get CH now (since its likely not any better than the under 10k 1080p solutions) doesn't seem worth it (at least to me).
