Page "Pan and scan" Paragraph 4

However, films shot at aspect ratios of 2. 20: 1, 2. 35: 1, 2. 39: 1, 2. 55: 1, and especially 2. 76: 1 ( Ben-Hur for example ) might still be problematic when displayed on televisions of any type ( though connoisseurs of films might dispute this ).

But when the DVD is " anamorphically enhanced for widescreen ", or the film is telecast on a high-definition channel seen on a widescreen TV, the black spaces are smaller, and the effect is still much like watching a film on a theatrical wide screen.

Though 16: 9 ( and occasionally 16: 10, mostly for computers and tablets ) remain standard as of 2012, wider-screen consumer TVs in 21: 9 have been released to the market by multiple brands.
