The size of a screen is usually described by the length of its diagonal, which is the distance between opposite corners, typically measured in inches. It is also sometimes called the physical image size to distinguish it from the "logical image size," which describes a screen's display resolution and is measured in pixels. [1] [2]
Find the optimal distance for a given screen. Example: for a 4K UHD screen 140 cm high (112 inches diagonal), the optimal distance is 140 × 1.6 = 224 cm. Find the right screen size. Example: for a 1080 HDTV used at a distance of 250 cm, you need to find a screen whose height is close to 250 / 3.2 = 78 cm (63 inches diagonally).
A Dutch word meaning "little quintal"; a measure that was a half of a barrel. 1 barrel = 4 firkins = 2 kilderkins [36 Imp. gal.] 1 hogshead = 6 firkins = 3 kilderkins [54 Imp. gal.]: 1 butt = 12 firkins = 6 kilderkins = 3 barrels = 2 hogsheads [108 Imp. gal.] {Beer bottles in South Africa were different from in other countries.}

Organic light emitting diode (or OLED displays) is a thin, flat panel made of glass or plastic used for electronically displaying information such as text, images, and moving pictures. OLED panels can also take the shape of a light panel, where red, green and blue light emitting materials are stacked to create a white light panel.
A generic LCD TV, with speakers on either side of the screen. Liquid-crystal-display televisions (LCD TV) are television sets that use liquid-crystal displays to produce images. LCD televisions are much thinner and lighter than CRTs of similar display size and are available in much larger sizes (e.g., 90-inch or 230-centimetre diagonal). When ...
Masked (or flat) widescreen was introduced in April 1953. The negative is shot exposing the Academy ratio using spherical lenses, but the top and bottom of the picture are hidden or masked off by a metal aperture plate, cut to specifications of the theater's screen, in the projector. Alternatively, a hard matte in the printing or shooting ...
The diagonal screen size of a CRT television is limited to about 100 cm (40 in) because of size requirements of the cathode-ray tube, which fires three beams of electrons onto the screen to create a viewable image. A large-screen TV requires a longer tube, making a large-screen CRT TV of about 130 to 200 cm (50 to 80 in) unrealistic.
