While THX still contends that the optimum viewing distance is a position where the display occupies a 40-degree view angle for the viewer, they too provide a range recommendation. The minimum viewing distance is set to approximate a 40-degree view angle, and the maximum viewing distance is set to approximate 28 degrees. [26]
The latest version of the ITU BT.500 uses it: "The design viewing distance (DVD), or optimal viewing distance, for a digital system is the distance at which two adjacent pixels subtend an angle of 1 arc-min at the viewer's eye". The TABLE 1-1 :
In a technical context, the angular range is called viewing cone defined by a multitude of viewing directions. The viewing angle can be an angular range over which the display view is acceptable, [1] or it can be the angle of generally acceptable viewing, such as a twelve o'clock viewing angle for a display optimized or viewing from the top. [2]
It can also improve your viewing angle if you have to mount the TV higher than the ideal. The Rocketfish Tilting TV Wall Mount RF-TVMLPT03V3 tilts a full 10 degrees down (or 5 up), giving you ...
The rule of thumb is to multiple the diagonal length of the TV by 1.2 to determine the ideal viewing distance, Samsung's Fishler said. ... 2024. It was updated on Nov. 5, 2024 to correct that TV ...

The viewing cone refers to the effective viewing directions of an LCD display, as seen from the eye. This collection of angles resembles a cone. The concept has been introduced as an international standard ISO 13406-2, which defines it as the range of viewing directions that can safely be used for the intended task without "reduced visual performance".
Usual deflection angles were 90° for computer monitor CRTs and small CRTs and 110° which was the standard in larger TV CRTs, with 120 or 125° being used in slim CRTs made since 2001–2005 in an attempt to compete with LCD TVs.
