Talk:Curved screen

The whole page seems to be an ad for curved screens. The bottom line is reality is that curved screens are a tradeoff where sacrificing the perfect image quality for the sweet spot allows improving average image geometry for near sweet spot watching locations. The image is always inferior quality even for the sweet spot seat because the original camera most probably had flat image recording surface (CCD, CMOS or film) and the most true display of this information is always a screen with identical geometry - that is, a flat surface.

In addition, "pincussion effect" is normally used to refer lens rendering artefact where original flat square is not correctly projected as flat square on the recording surface. The fact that corners of projection screen end up darker without any special measures is called 'vignetting' and it does occur for both recording the original scene (camera) as well as for display (movie projector or home theater projector). — Preceding unsigned comment added by 80.223.134.4 (talk) 05:53, 16 August 2016 (UTC)[reply]
