You then need a device (some PJ's are internal, or you'll need a scaler) to apply a stretch mode to your source image to distort the pre-lense picture that the lense reverses.

Net result, you use the entire resolution of your projector for the image, with out wasting pixels to have the PJ draw black bars.

Here is a link to the FAQ:

Thanks for the quick reply...I have a favor to ask though from you people with this set up. Will someone post a screen shot with the lens not in use then one with the lens in use. Kind of will let me see what its doing.

Yup, the other movies you are referring to are basically 2:35 or 2:40 aspect. They have black bars top and bottom because they are actually wider than your 16:9 display. So when the image is stretched up and down to get rid of the black bars everyone looks tall and thin. The lens then stretches the image left and right and corrects the stretch and evens things out. Our screens (for those of us with 2:37 screens, I go in between ratios) are wider than 16:9 by a factor of 33% so therefore the entire screen is filled by this process.

Another place to get a good understanding of what's going on is at one of the lens web sites. Personally, I have a lens very much like oman's, but I bought it from Prismasonic.
Check out that web site, lots of info, screen shots, and a good explanation. I know it helped me get things under control. It also got me hooked on the idea though, so be careful!

Here are some pics which I had posted in the prism thread when I first got and setup my prisms. Just be aware that this was when I had a temp setup with a bedsheet and I when I set the prisms up they were stretching the image a little more then they were supposed because I hadn't measured the stretch just yet I was eyeballing it.

No lens


No lens, vertically stretched by the projecter as this was 480p and the projector can handle this. For HD I use an external scaler.


With lens in place, disregard the green push as one of my component connection cables had come loose.


This gives you a quick but crude example of what the whole CIH 2:35 thing is about and how more grand it can be.

Now that you mention that Ej, Panamorph has a great video on their website about cinemascope.

So really you dont see "more" of the movie like going from 4:3 to 16:9? BUT it just gets rid of the bars right?
post #427 of 1056

Yes basically, it also improves the resolution also because none of the pixels are being wasted on the black bars.

OK...kind of what I was thinking after reading so much...Its nothing im interested in or worrying about as the bars dont bother me at all and the resolution wouldnt be better by much " i wouldnt think?" Its a neat idea and Its cool some of you go with it..

Looking good people...Love learning so much here..

Big gave me an idea earlier today on Shawn's thread which will hopefully work. If it doesn't show as a full 16:9 image I wont be able to stretch to scope and it might not look as nice but it would probably still look pretty good as a warm up intro.

So this is what I've come up with so far.

I was able to piece together a curtain image with the sample of my sign from Bud and lettering into power point to hopefully make this a slide that I will be able to display on the projector with my laptop and have the projector capture the image. Hope to try it out this weekend, worst comes I'm sure I can make it a Jpeg for the PS3 or some other solution.

Do you know if there is a way I can make something like that to start up on my Sony VPL AW10? OR does it have to do with your dvd player? I can make the startup screen as im good with PSCS but just not clear on how to get it from my idea to my screen??

Such quick studies on this forum. Nicely done.

Not sure it if somehting that the AW10 can do or not. Your manual should tell you, I just know it's a feature on the Epson. I think I have seen as an option on a Optoma as well, so maybe this is pretty common with projectors. I suppose one if all else fails most DVD players play jpegs now a days and you can simply program your universal remote to start up your dvd player and play a disc you leave in there. Probably best if you have a back up dvd where you could leave it all the time.

I don't get it, do you need your laptop hooked up every time you want to display this image?

Looks awesome btw

What do I look for in my manual for this feature?

I just looked at mine and it appears hopeful for me to be able to display it as a 16:9 image.

In my manual it was under "Screen Options" then "User's Logo" and it shows pics of an image being captured.

But then you'd have to remove it anyway to play a movie ?? Ideally, the 'welcome' would show up first and then you could just hit play on the URC. But obviously if it's a disc in the player, you'd have to get up and change it and then load the movie. Not exactly seamless. That's why I was hoping the JVC would have some kind of default when it warms up.

This is true unless you have a spare or bargain bin dvd player which does jpegs that you can dedicate to this and simply connect it via composite, s-video or possibly component video to the proj. or if you have a switching receiver you can connect it thru that. Then you just need to program a macro that will switch the inputs either on the proj. or receiver once you hit a certain command.

mikieson, I took a peek at the manual for your projector and it appears as though you are out of luck as far as the projector being able to do this.

I missed your post earlier Shawn,

No I would only need to hook up my laptop once, or actually add as jpeg to be viewed on the ps3 or a dvd or whatever medium I can use to view it with the projector. Once it's being displayed by the projector it has the capability to take that image and capture it and stores it in memory. Almost like when some tv's have a freeze option and it freezes the image being displayed. Once captured I can set it so that the image is displayed during the warm up, when there is no signal or if I hit blank so the video being watched stops projecting.

I haven't set this thing up yet and I'm already making changes.
I slightly modified the lettering and made the T in the a capital.

I keep debating if you need punctuation - e.g. "Welcomes you. Enjoy The Show!.

- - - This kind of stuff isn't going to help you convince the wife to meet people from AVS.

LOL your right about that.

Good point about the punctuation, what do you think now?
post #443 of 1056
I do this in powerpoint too.

I like the exclamation point at the end - not sure about the period.

Maybe -

Welcome To The
Highland Cinema
Enjoy The Show!

Humph! I emailed myself the files so I could keep tweaking at home and while the image comes over as is when I open the power point file the lettering style is different. Apparently my version doesn't have all the same script styles. So I had to improvise and go with a couple of different Script styles.



It think the first one is closer to the old style but slightly different, in particular the E which I preferred the old style E. The one on the right is more formal but not sure if it's better. I could always re-do at work to get the old lettering back I suppose.
post #445 of 1056
All the different versions are good - but I do like the font on the first one better.

Perhaps without the image of the Stary night and just the name in regular Caps lettering.


That's it till I actually try this out.
post #447 of 1056
If you strip the logo out - I'd move "The" down w/Highland.

I'll stop now. You shouldn't be taking design advice from accountants anyways.

Nah, that's cool. The great thing is that I could play with it as much as I want to. I'll try it out first and then take it from there.

Darn it, it doesn't do a full 16:9. It actually looks like 2:35 before vertical stretch and the lens. I may actually be able to manipulate it with my scaler once I get that back from Digital Connection, we shall see.

Hey oman,

I don't know if I've ever posted on your thread. Really enjoying your build and your documentation of it.

The idea of having your projector start up with your own image is pretty cool!

I tweaked your design a little, just to see what I could make it look like. It's all yours if you want it.
