What would you prefer: 3DTV or CIH Projector?

post #1 of 39
Thread Starter 
I'm having a hard time deciding for myself. With the 3DTV, you don't really have to worry about spending ridiculous amounts of money to make it output things in 3D because it already IS 3D, but the experience with a 55" TV probably wouldn't be as good as the experience of watching it in 2D (or 3D if you somehow hook up 2 projectors) in 120".

I've been looking at the Panasonic PT-AE4000U projector, which was the only projector I could find with a really high contrast ratio, and if I were to go CIH I'd get that. But then getting a screen and all that stuff. Ahhh.

Hands down CIH. Once you have the setup, you always have the option of upgrading your projector to a 3d one in the future.

Hands down 16:9.

Seriously, you have to make up your own mind on that one. I think a big screen is more important for 3D, and that includes height as well as width. So, I'd pick 16:9 rather than scope. My choices are limited, but especially since I watch more 16:9 than scope, it's an easy choice for me.

1080p 3D CIH is the end game for me. Seriously.

I have the pj the op is considering (Panny AE-4000u) and a 2.35:1 screen, and after going CIH I could never go back.

However, I'm also a 3D nut, so my first foray into HD 3D will likely be via a direct-view set in a room other than the HT.

Only when I can find a pj that can do 1080p 3D and CIH with the same quality, ease, and affordability as the AE-4000 will I think about replacing it. Luckily Panasonic seems committed to both 3D and CIH (via lens memory), so I have hopes of realizing my dream before I'm too senile to enjoy it.

16:9 is the proper choice for many people including myself. I dare say most people even. I am going to just add 3D to the mix and not replace my 2D setup.

Done! And why not throw in a deeply curved screen also!

I'm seriously considering this route, too. I'm thinking a 65" Panasonic plasma may be a good choice, based on what I've seen so far, but I'm anxious to check out the Samsung plasmas, too.

Since I'm width limited in my main home theater, 16:9 is the only size screen I'm going to have. CIH is not something I'm concerned about. I watch a lot more 16:9 content than 2.35:1, anyway, and I want my biggest image to be 16:9. I'm also hopeful Panasonic will announce an affordable front projector before too long, but I'm open to different technologies. Before the Panasonic 4000, I've owned mostly DLP projectors.

+1

CIH projection 1st, 3D when there are decent projectors that can do it available.
post #12 of 39
Unless I am convinced otherwise, my HT room will have both. I will actually do rear projection with (likely) three 720p projectors (Nvidia 3D Vision Surround), but I will also have CIH with a 1080p projector. I'll have as much screen width as I need with the 3D Vision Surround setup. Plus I'll have the 3 projectors to show at least 3 sources at once for regular TV viewing. Anybody else doing/panning anything like this?

CineVERSUM Unveils Cinemax Kit

Quote:


CineVERSUM is proud to announce today their new Cinemax Kit. This lens assembly is compatible with all the BlackWing MK2010 series as well as any CineVERSUM Theater Screen. The lens is an anamorphic lens and will stretch the natural HD (1920 x 1080) resolution image from a 16:9 aspect ratio to a 2.35:1 aspect ratio. The expanded ratio eliminates the black borders that are commonly found above and below a widescreen display. Other features of the new kit includes a 25% increase in brightness and the ability to switch back to a 16:9 aspect ratio in order to watch TV, sports, or video games. The Cinemax Kit is expected to release soon, but the retail price has not been listed yet.

The biggest 3D movie yet, Avatar, can't even be properly displayed on a CIH setup.

So definitely a gigantic 1.78 screen, the biggest you can fit, and 3D- just have to hold out a little longer. Besides, it's not like we're bursting with 3D material any time soon.

I am not against 3D but a very wide curved screen also has a 3D effect without glasses. Cinerama started the 3D craze and widescreen (2.35:1) was an economical solution. I will keep an open mind but I don't want to go back to 1.78:1 aspect ratio. I want the movie to surround me. Maybe todays 3D movies make a lot of money, but they also cost a bunch and take in some cases years while a conventional cinemascope movie can be produced in considerably less time and money. As great as Cinerama was other than a couple of follow on features it became too expense to film and produce in the quanity to met the needs of the viewing public.

OKAY this is really tight, but, I can already see this going up into the $5k range.

Basically, I'm gonna move in with all my buddies and I want to have a "central entertainment" in the apartment. I'm gonna have my LCD in my room and my buddies will have THEIR stuff, but when we have guests over or all want to watch a movie together, it's the living room with the PJ and the CIH/CIW screen.

How much do anamorphic lenses go for these days?

I've gone with a 2:35:1 theater myself. It was basically the ultimate before all this 3D stuff came along. Now that I've gotten used to watching 2:35:1 movies the way they're meant to be watched, I'm not sure I can go back to watching 2:35:1 movies in a 16:9 frame. I just don't think I can do that. Take Monsters vs. Aliens for example. That is a 2:35:1 movie. Why not see it like people saw it in the movie theaters in it's true 2:35:1 form, but also in 3D, and also in 1080p?

Wouldn't it be possible to just have two AE-4000u's and use them in a dual-projector setup? I'm seriously considering a dual-projector setup, but I'm just not sure how it's all going to work out. My main concern is offset, and lens shift. My ceiling isn't very tall, and I have to ceiling mount. Offset is a huge issue for me, and lens shift and zoom is a huge issue as well. I'm currently using a Optoma HD71, which is a DLP projector with all the lens shift you need (for Poor Man's Zoom Trick), but it's only 720p. Luckily, it has an offset that I can work with. I'm just not sure how I would stack two projectors, keep them from blowing each other up due to lack of heat dissipation, and also dealing with all the offset issues, and zoom issues. It's a logistical nightmare. I'm sure it can be done somehow, but I just have to wrap my brain around it.

The problem with using two projectors is that since they are placed either SBS or one over the other they can not be displaying exactly the content for each eye at the same verticle or projection angle onto the screen. A second problem is that no two projector lens are exactly the same you can have convergence issues of the two images. The only dual projector systems that appear to resolve these issues are the ones that use two projectors but which output their images through the same lens.

So, even if one has vertical and horizontal lens shift, you're still screwed?

Even if the projectors are identical, with identical bulb usage?



I know that some people out there are already using a dual-projector setup, and it's working for them, so how are they getting it to work correctly? Tom's Hardware Guide recently had a special report on how to do a dual-projector setup. Here is the report:

No 2 projector lens are ground exactly the same so there is no guarantee that right eye image and the left eye image will be on top of each other over the entire surface of the screen.

Don't you just run test patters on both projectors, and continue to adjust them until they line up perfectly? I know it's easier said than done, but I don't think it's impossible. Otherwise, nobody would ever use a dual-projector setup.

As long as the optics in the two lens are almost identical then it should be possible over the entire display surface.

That's why it would pretty much be mandatory to own identical projectors, and it would also be important for the bulbs of each projector to be of the same age and vibrancy, although this might actually prove to be the more difficult issue in the long run...

CIH projection rig for me thanks!

lol I just realized that the thread is asking would you want a 2D projector or a 3D LCD. I'd take the 3D projector
post #29 of 39
I also am looking forward to 3D Projectors hoping Panasonic will come out with one, I mean 3D TV look good but it's too small even the 63inh Samsung for me anyway I love my 2.40 screen and will never go back.

Thanks.

I tried searching Google but I'm still unclear as to what a CIH projector is. Can you explain a little? What are the main advantages and disadvantages (if any) of CIH projectors?
