I notice now so many DVD's are Anamorphic Widescreen or the 2.35:1 ratio.. Its weird to not see many 16:9 1.85: 1 Dvds any more.. So any thinkin maybe a projector company will do a Anamorphic Widescreen Projector?

I don't think so. Remember, there's always HDTV. If you want anamorphic, do it like the theaters do, get a lense.

Not quite sure what you mean by anamorphic projectors. If a projector is widescreen as many are now. They already know how to unsqueeze the picture. Remember that 16:9 non-anamorphic DVD´s will still show black bars on a 16:9 projector.

I was thinking about this before I bought my projector a long time ago. I got a 16:9 proj for a couple of reasons - I mostly watch HD and DVD on it, a little 4:3. Now, as you say more movies are 2.35. So I have bars on the sides for 4:3, full for 1.85 & bars on the top for 2.35.


Thought about getting a lens to streach like those with 4:3 proj do for 1.85 - but not sure if this would work.

ramick,


a 4:3 -> 16:9 like the original panamorph or the ISCO will make a 16:9 native projector image into 2.35:1.

I just did the math, I never suspected. (4/3)^3 = 2.37, which is pretty darn close. As (4/3)^2 is 1.77, adding an anamorphic lens meant for 4:3 to 16:9 conversion goes the rest of the way, well, 1% too far, but I bet that the abberations caused by any anamorphic lens would be more significant than that.


What sort of videoprocessor can output a properly formatted signal for such an arrangement? Does it take into account that the vertical position isn't the same between all DVDs?

That may be possible to zoom out/in?


Has anyone tried this - having a 16:9 proj and adding a lens to get 2.35:1 for that source mat?

One thing I am puzzling with is what software is used to force the change in aspect ratio and to crop out the black bars?

Aspect Ratio control is built into both the TheaterTek SW DVD player and Zoom Player front end...


HTPC rules in configurability at the expense of complexity...

re: "Anyone think that there will ever be a Anamorphic Widescreen Projector?"


Yes- it's called the PLV60/13HD. ;)


I have owned both a Panamorph P752 and an ISCO2. I tried these lenses with my previous XGA LCD projector, a Mits X100.


IMHO, the results I get with the PLV60 are superior.


I feed a progessive, anamorphic 1024x768p image to the PLV60 from a HTPC. The PLV60's "Full" mode then does the anamorphic horizontal stretch digitally, the same thing a commercial cinema or ISCO2 does optically.


Since the HTPC does the digital-domain de-interlacing and scaling to 768p, and since the PLV60's scaler is well regarded and is only scaling in the x-direction, this approach gives me a "digital domain ISCO2" :).


Yes, I could feed a 1360x768 signal from the PC, and I probably will once I get the pixel-perfect timings at 1360x768 worked out. I have pixel-perfect aligment in 1024x768 mode in the center of the PLV60 LCD panel now, so using the PLV60 "Full" mode for a "digital ISCO2" is a great solution for simplicity and quick changes from XGA gaming to DVD movies (one resolution does-it-all) :)

Actually, the orignial poster was asking for a 2.35:1 projector, not a 1.85:1 projector.

The PLV60 is 1.78:1 with 1366x768 square pixels.


Anamorphic DVD's can be 2.35, 1.85, 1.78 or even 2.4:1. The size of the black bars varies, but the increase in vertical resolution is real for any anamorhpic aspect ratio.

...I've advocated *really* strong prescription glasses for astigmatism for your HT viewers as an alternative to anamorphic lenses (anamorphic glasses for each member of the audience ;) ) .
