Curved 16:9 screens - Benefits? Pros and Cons?

post #1 of 14
Thread Starter 
I am thinking of getting a 10 feet wide AT screen. TO curve or not to curve?

Some say a curved 16:9 screen would give you that Imax experience. True?

Also, what happens if you play a scope movie on a curved 16:9 screen? Any issues?

Don't you need an anamorphic lens or a projector with anamorphic capability for a curved screen?

Not sure if you need anamorphic lens for curved 16:9 screen. Prob not...

I just wanted to know if it's worth getting 16:9 anamorphic and what's the benefits?

Imax is curved.. and it's not Scope... and it's great!

For 16:9 probably not. 2:35:1 would be the better aspect ratio for a curved screen.

The “immersion” factor on a curved 16:9 screen is mostly a myth.

Immersion comes from the wide-angle (Cinemascope) presentations where your peripheral vision is picking up movement from the sides of the screen while you are focused on the center picture.

16:9 format is popular for TV sets because your eyes can easily take in the whole image without extra stuff happening off to the sides.

This is why theaters are 2.35-2.40 and TVs are still 16:9.

Most curved screens are designed to be used with an anamorphic lens as the curve corrects the pincushion effect.  However, there is some advantage to curved screens when used with an angular reflective screen.  With gain screens some of the light towards the side of the screen is not going to be reflected towards the audience but if you curve the screen you will get better uniformity for the audience.  But, you may introduce a slight pincushion/ barrel distortion effect.

I actually read that. But also, read from Imax's site about curved (squarish) screens. I think the 16/9 is very similar to Imax ratio.

The 'periphery' vision stated in the article only applies to the left/right, but in a more squarish screen, if it's big enough, it applies left/righ and top/down (exactly like how imax is), and could actually give you an even better immersion effect than just the scope type screens.

Chris from SemourAV basically said the same.

I asked Chris from SemourAV and he said their curved screen uses a 40' diameter curvature and that the curve is slight enough that it won't get the barrel effect.

If you think otherwise, please chip in... I am still deciding. Don't want to make a mistake

I've got a 120" (16:9) screen which I sit 15 feet from. I tried imagining it having a curve to it and came to my personal conclusion that it would have to be a much larger screen in order for it to have the immersive quality you're looking for.

The distortion of using a curved screen without an a-lens is probably minimal at that degree of curve.  I don't think you will gain anything for picture quality unless using a gain screen, but there is a certain cool factor to it.

I am thinking of sitting about 11-12 feet away or get an 11 feet wide screen and sit about 12-13 feet away (front row).

But not sure if the Sony hw50es will be bright enough (in 3d mode).

I could add an A-Lens later.

BTW: If i used an A-Lens on 16:9 screen, what happens when I watch:

1. Scope movies
2. regular 16:9 movies?

Do i have to move the lens or use the A-Lens for both formats?

you can either:

1) use motorised A-Lens + manual/ motorised masking system
2) lens memory (Sony HW50ES don't have this feature) + manual/ motorised masking system

just found out that HW50ES offer anamorphic modes that save you from adjust the A-Lens

by the way, do you want CIH or CIW?

Uh Uh...

650 Pounds of Speakers just arrived via FedEx. Now stuck at customs. My neighbors should be thanking me soon for helping them discover how flimsy their houses are when their 'concrete' structures starts showing cracks when I turn these beasts on... it's an early warning system for unsafe structures... that way, they can repair it before the BIG Earthquake shakes KL to the ground...

CIH = Constant In Height

CIW = Constant In Width

Congrats on the arrival of your Orbit Shifter eek.gif do let me know once you have received & set it up, I'll love to audition it once in my lifetime biggrin.gif I bet all custom officers must be scratching their head & wondering what the hell is that gigantic box biggrin.gif

Well, since my screen is 16:9, it's Constant in Width... if it's scope screen, then it'll be CIH... they imply each other...

Anyways' that's a cool DIY masking system...
