Re: Best LED TV bang for the buck
The imaging scientists and engineers who designed the HDTV system conducted extensive human perceptual factors research to determine the optimum viewing angle for a 1920 x 1080, 1.78:1 aspect ratio screen. Their recommendations are based upon average human visual acuity, and at what distance a certain pixel size starts to become detectable to the viewer. The goal is a smooth, sharp, natural looking image without revealing the component parts of the display. That viewing distance is approximately 1.5 x the diagonal measurement of the screen. This works out to a 30 degree viewing angle. Such a distance is a good starting point for determining what works for any individual viewer, using a particular display technology.
There are differing recommendations quoted by some sources. Frequently, they inappropriately base their opinions on film projection technology. Video is not film and digital video displays cannot be equated to projected film imaging characteristics.
