How 2.40 Screens Work?

THINK YOU ALWAYS GET 1080P, "TRUE HD" WITH YOUR 16:9 PROJECTOR OR FLAT PANEL?

Today’s big screen home theater projectors beautifully display the 16:9 aspect ratio of HD sports, documentaries, games, television programs and many small format movies for a great multimedia experience. It’s a great image, but it’s not perfect.

A 16:9 screen has a width that is 1.78 times its height. But over 70% of all major motion pictures are filmed in a wider cinematic aspect ratio of at least 2.35:1, where the image itself is 2.35 times its height or greater (most movies made since the mid-1970s have been shot with the 2.40:1 ratio). In order for these films to fit within the smaller 16:9 screens, the image is sandwiched between two black bars. Those black "letterbox" bars represent a surprising 25% waste of the display’s claimed "1080p" resolution. Rather than taking advantage of the full 1920x1080 resolution of your flat panel or 16:9 projector, letterboxed movies are generally encoded at a mere 1920x810. What happened to the other 270 vertical rows of pixels? Over half a million pixels are lost to create those two obtrusive black letterbox bars.  

 

 

This is how major motion pictures look on a standard 16:9 screen or any flat panel TV. Recognize those annoying black bars?

This is how major motion pictures look in true cinema widescreen format when pairing a Panamorph anamorphic lens system with an HD 16:9 projector and a wider 2.35.1 or 2.40:1 screen.

With a Panamorph lens, those annoying black letterbox bars are gone! In addition, you gain over 30% more brightness and resolution plus an 80% larger image (compared to a letterboxed image on a 16:9 screen of the same height).

Panamorph lenses paired with 2.40:1 screens provide 80% more image area than widescreen movies shown on conventional 16:9 screens of the same height. Yes, you read that right – 80% more immersive, dynamic, and involving.
