2. 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.

   Screen-door effects are more noticeable than LCD when up close, or on larger sizes. [53] New models are no longer produced. Colored sub-pixels may age at different rates, leading to a color shift, although some models will scan pixels to even out wear and prevent this shift. [54] Sensitive to UV light from direct sunlight.

4. Display size - Wikipedia

   en.wikipedia.org/wiki/Display_size

   On 2D displays, such as computer monitors and TVs, display size or viewable image size (VIS) refers to the physical size of the area where pictures and videos are displayed. 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.

5. Cathode-ray tube - Wikipedia

   Flat-panel displays can also be made in very large sizes whereas 40–45 inches (100–110 cm) was about the largest size of a CRT. [7] A CRT works by electrically heating a tungsten coil [8] which in turn heats a cathode in the rear of the CRT, causing it to emit electrons which are modulated and focused by electrodes.

6. 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).

7. List of common display resolutions - Wikipedia
