2. Display size - Wikipedia

   en.wikipedia.org/wiki/Display_size

   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]

3. Optimum HDTV viewing distance - Wikipedia

   en.wikipedia.org/wiki/Optimum_HDTV_viewing_distance

   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).

   The optical box that housed the tube was also designed to shield the X-radiation produced by the tube. The optical boxes were produced in three versions for 15 + 1 ⁄ 2, 17 + 3 ⁄ 4 and 19 + 7 ⁄ 8 inch [diagonal] screens. Two further sizes were available for front projection onto 44 or 52 inch screens.

   So if the screen is 60" wide, the projector needs to be 120" from the screen. A video projector (lens) with a throw ratio of 0.4 or less would be positioned relatively close to the screen, and would be considered a "short throw projector". [3] A video projector that must be positioned very far from the screen would need a "long throw lens" with ...

6. Large-screen television technology - Wikipedia

   en.wikipedia.org/wiki/Large-screen_television...

   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.

   160×120 (19k) 160 120 19,200 4:3 UNNAMED UNNAMED A common size for LCDs manufactured for small consumer electronics, basic mobile phones and feature phones, typically in a 1.7" to 1.9" diagonal size. This LCD is often used in portrait (128×160) orientation. The unusual 5:4 aspect ratio makes the display slightly different from QQVGA dimensions.
