For the period from March 27-April 30, 2023, TV viewing of YouTube videos (excluding YouTube TV) was up 1.5%. […] YouTube, already the most popular streamer on big-screen TVs, last month built ...
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]
If the distance and width are known, calculate the throw ratio using the formula: R = D / W [1] If the screen width and throw ratio are known, calculate the distance using the equivalent formula: D = W x R. Although it is often stated as a single value (or range of values), throw ratio is a comparison of D : W. [2]
However, this optimal distance has the characteristic of being objective and simple to implement. 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 :
Two dual-monitor digital audio workstations Multi-monitor , also called multi-display and multi-head , is the use of multiple physical display devices , such as monitors , televisions , and projectors , in order to increase the area available for computer programs running on a single computer system.
In the fields of broadcasting and content delivery, multiscreen video describes video content that is transformed into multiple formats, bit rates and resolutions for display on devices such as televisions, mobile phones, tablets and computers. Additional devices may include video game consoles such as the Xbox 360, or internet enabled television.
As the display size increases so does the ideal viewing distance. Bernard J. Lechner, while working for RCA, studied the best viewing distances for various conditions and derived the so-called Lechner distance. As a rule of thumb, the viewing distance should be roughly two to three times the screen size for standard definition (SD) displays.
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".
