btokars -- Convergence adjustments are not possible, except by a factory repair facility - it requires complete disassembly of the PJ and remounting and allignment testing of the panels (they are not adjustable and it cannot be done in the "home"). Generally they are "in spec" (+/- 1/2 pixel) or better on most of them (occasionally, some units are delivered at or out of spec or have defective panels). They do not shift, unless the PJ has been dropped (or damaged in shipping).

For old PJs, some AVS members have attempted reallignment, but you do need the complete service and assembly manual. It is a big risk, and should not be done (at home) except as a last resort. For a new PJ, it's a lot cheaper to send it back to the factory for repair/replacement.

CRT PJs are a lot easier to adjust, but even those are not easy if a single tube is replaced. Re-tubing is usually done as a 3-tube assembly - already factory aligned tubes, which only require magnetic (minor) adjustment. That's a different set of parameters altogether.

Another way of saying it is that the CRT R, G, & B pictures are developed by beam positioning - LCD (or any 3 panel digital technology) develop the picture from the fixed allignment of physical picture elements (pixels) which do not depend on electrically controlled positioning.

Cedia is going to be very interesting with this pj at this price point. I expect this thing to be 2k by cedia and more challengers around 3k

Well, thanks for that info. That is good news. I'm another one who was going to pull the trigger on a Mits 720p but now it seems like a good time to slow down and wait a few months. Fortunately, my last replacement lamp from Warrentech for my NEC HT-1100 is sitting in a box ready to be installed when the current lamp dies (probably in a a few weeks) so I can still sit on the sidelines and watch this 1080p price race to the lower end, transpire. No doubt there are now a lot of us in that position. I wonder what, if anything Mits will do.

Huh? Who is biased against epson? The PC review for thsi model is positive. Art at PR liked Epson's last model and Cine4home comes off as liking epson models.

Who exactly is biased against them?

Art (www.projectorreviews.com) used to sell Epson when he was in that business. He stated that they provide very good factory support.

I think that SbWillie was referring to PJC's review of the Epson 400, which they didn't like (they gave it a bad review compared to their gushing 5 star review of the AX100 and Z5). Art found it to be comparable to the Z5 and both sharper and brighter than the AX100. He said it's downside was a noisier fan.

BTW, Art announced that he has gotten the Cinema 1080 in for review. He usually takes a week to do the review, so it should be posted on his site by next weekend (I'm guessing).

I re-read the PJC "review" (it doesn't say much, except that they liked it). However, they mentioned that it uses an E-TORL lamp. I was curious as to what this was, so I did a little searching. Here is Epson's white paper describing this lamp design: http://www.epson.co.jp/e/newsroom/te...0512single.pdf. They claim that it provides more lamp light output over a "standard" lamp deisgn.

The potential down-side is that this lamp might require a more precise alignment of the lamp housing elements, However, an elliptical reflector is cheaper to make than the standard parabolic reflector. It's interesting that PJC said that the price of the lamp assembly is $349.

NOTE: I think (SWAG) that this type of lamp design may also be used in the higher output automobile head lamps.

So has anyone confirmed (or denied) if this projector can do the vertical stretch needed to use an anamorphic lens for the 2.35 CIH setup?

As far as 2:35, I asked earlier in the thread if previous Epson's did the vertical stretch. Two posts later dreamtheater stated that this model and the previous models would need a seperate video scaler to achieve 2:35. I also looked at the online manual for the pro 1080 and the home 720 model and neither seem to indicate that they offer vertical stretch. They do have some aspect adjustments but not the one were looking for I believe.

Yes, I was actually just (gently) corrected by our regional Epson Rep ... so I came in here to correct myself (I had previously stated 1 year as well).

The unit does have a 2 year warranty as opposed to the Pro1080's 3-year.

I am still waiting for clarification whether the Home1080 has the same "no dead pixel/direct exchange warranty" for the life of the warranty as the Pro1080.

Although, as I mentioned earlier, I would figure bundling a 5-year in-home warranty (much like we see with the AE1000U) for free would solve this either way.

I am curious if this can do 1080p from VGA and component in the event that I tried to use my 360 to connect to it.

The PJC review didn't mention anything about that except for their "Video Compatability" list:

There was no mention as to which inputs they were referring to.

Art's (AVS member = presenter) review should be posted by the end of the week (www.projectorreviews.com). We'll have to see what he says.

This thread allows me to re-visit stuff we were chomping on in the original TW1000 thread.

I find the comparison of the Mistubishi and Epson weird. Dealing with the auto iris functions OFF, the Mitsubishi gets really high at 1300:1 in it's "rear-bright" mode and yet is only 720:1 in D65. The Epson gets 1150:1 in theatre black D65. I suspect this is sort-of like a factory colour calibration using a filter. My Hitachi TX200 is capable of a 950:1 in correct colours with iris off. I suspect that comparing my Hitachi TX200 with the Epson right off the bat, I should see higher contrast with the Epson. It's a 20% increase in numbers. What would make it more noticabley better looking in terms of contrast AND black levels is that I suspect the Theatre Black mode probably lowers black levels much like what people achieve with colour calibrating with a filter. Who knows how good the Hitachi TX200 could get with a colour calibration? Is this not what is happening inside the Epson in it's theatre black mode? Many say colour calibrating brings lower black levels at the cost of lower lumens and lower contrast ratio so what is going on?

Still, just going with the numbers, I think it's obvious the 1080 C2Fine lcds do offer improvement. I guess we just want more. I mean, if you've got 1150:1 from the Epson and 12000 to 15000:1 with the JVC RS1 both without use of an iris... wow, that's a huge difference.

FYI - yesterday Tom Huffman posted a great write-up of the tw-1000 in the original thread. As far as I know he is the first ISF certified calibrator that has had a chance to take an extensive look at the projector.

First, read the post refered to by cathor: http://www.avsforum.com/avs-vb/showt...&#post10187266.

Secondly, wait for Art's review by the end of this week (www.projectorreviews.com) - I feel like I'm playing a broken record.

No recommendations on where to buy (see the AVS Alliance Members links at the top of this web page - we can't post where to buy anyway, it's against the forum rules) and what screen to use (refer to the screen threads). Art uses a 106" Carada Brilliant White screen (http://www.projectorreviews.com/advi...Qs/advice2.asp). He also has a number of screen reviews (and comments).

That's part of the Silicon Optix HQV torture test DVD. They test the ability to correctly decode the various modes of generating video material. See http://www.hqv.com/benchmark.cfm for the HQV test DVD page. The discussion of the cadence tests is here: http://www.hqv.com/technology/index1...C57FEA865EA603.

The primary cadence that should be handled corrctly is the 3:2 pull-down (used in the conversion from 24fps movies to 30fps video - but that's in your DVD palyer and not in the PJ). The Epson 1080 does pass the 3:2 24fps test, if you'll notice.

PS -- Art's review hasn't been posted yet.
