Biggest screen my wall can fit

I built the frame for 2.35, image size 145.5" w by 62" h but was disappointed with the 16:9 image within it (110.2 x 62). When I project the largest 16:9 image my wall can accommodate (136.9 x 77) the 2.35 image with those dimensions are also disappointing.

So I was wondering if anyone has just built the biggest screen their wall can fit that isn't a particular aspect ratio and uses masking for each aspect. The biggest screen image (frame adds 7 inches) I can fit is 145.5 w by 77 h. This gives me a 2.35 screen image of 145.5 w by 62 h and a 16:9 screen image of 136.9 w by 77 h.

Since this is my first home theater just looking for any pros/cons. Projector is the Panasonic 8000ae. Will be watching 60% movies, 30% video games, 10% sports.

Thanks.

That is a lot to think about. If i were you, i would look at what aspect will be viewed the most and use it. If you go with the 16:9 screen, you would have to mask the top and bottom, if you go with the 2.35 you would have to mask the sides for 16:9 or 4:3. As not every movie is in a 2:35.1 or 2:39.1 ratio.

If it was me, i would go with the 16:9 screen and constant image width. You can either mask or ignore the black bars on 2:35 content. I know a lot of people talk about zooming, and all, for me i like the content delivered in it's original aspect ratio, so black bars are not a problem with me.

Thanks for the reply. I will build masking for whatever screen size I chose but I'm still leaning towards the biggest screen possible so I have the best of all aspect ratios.

You're building what is called a "constant area" screen. I know there's a few folks around AVS that have done it, with masking IIRC. There's certainly 4-way masking systems on the market, but be sitting down before you see the cost...

Some of the masking systems I've seen cost more than my projector, speakers and receiver. My plan is to use velvet covered foam board with magnets to attach.

I would check out http://www.seymourav.com/default.asp for a constant area screen. Plus it seems like Chris can custom build it to fit the size that you want.

Out of curiosity, did you try adjusting your seating so the 16:9 was an enjoyable size with the scope setup?

See what an anamorphoscopic lens can do, see movies the way they were meant to be seen

I didn't consider that, I'll give it a try. While the seating is the last item to purchase I have seats that can replicate the position of the theater seats. The first row of four is 15 ft and the secon 19 ft from the screen. Thanks.

Sorry to bring back an old thread - but I'm facing the same question right now.
I'm thinking of getting a custom 2:1 screen (140” wide X 70” high), and use it for both 2.35:1 (140" X 59") and 16:9 (125" X 70") content.

I'm thinking of 3 possible methods:
1) dual-screen - I saw on the market several offers of one case holding two screen sizes & formats
2) 4-way masking - I'm still trying to find a vendor who does that, as my screen (will be) electric & foldable, not fixed.
3) SI Black-Diamond completely black screen - where I'm theorizing that the completely black nature of the screen means no masking will be required for either format (still trying to find out if that's true).

Can you share how you ended up with your screen?

Thanks,
Shahar
