First, the use of different materials: computer monitors and monitors for video rates, the meaning is completely different, the monitor uses a "short afterglow tube" and monitor the use of the "in the afterglow tube" (both used phosphor, and display tube there are differences in the nature of color recognition. typically, though they have a smaller display a higher pitch or vertical refresh rate. but the ability to identify colors "short afterglow tube" monitors used only equivalent monitor "in the afterglow tube "1/5 or so). A high-end monitor uses only its phosphor itself is enough to sell a few high-end monitor. Display itself primarily as "Still" service, which is mainly used to image coordinates of text and special applications environment and show (strictly speaking not good performance monitor moving images (note the true sense of the image and the image the difference)). The monitor is designed specifically for motion pictures, it does not emphasize the display concepts such as pitch or vertical refresh rate, but the harsh emphasis on color recognition and identification capabilities (performance requirements for image absolutely neutral, natural, accurate, broadcast-color monitor does not allow the slightest image and color distortion and color cast).
Second, the input signal is different: AV color monitor input analog video signal, the computer monitor's VGA input RGB color digital signals.
Third, the resolution is different: Normal color monitor is generally 420 lines or 480 lines significantly depending on the computer is 800 * 600 resolution.
Fourth, the radiation levels are different: some do not have a color monitor radiation treatment (some manufacturers in order to make the image clearer, increase the line deflection voltage, resulting in electrostatic radiation), and the computer monitor must have radiation testing and certification, or simply using a liquid crystal display there is no radiation.
Five different refresh frequency: Normal color monitor at 50Hz refresh rate should be less (analog), general computer monitor easy to 75hz.
Six different anti-jamming capability: monitors the current in the design, power, temperature and resistance to electrical interference, capacity and redundancy electric shocks and the average time between failures are much larger than the display. Meanwhile monitor must also use fully shielded metal housing to ensure electromagnetic compatibility and interference.
Seven different ways to restore the signal: when the video camera, the light signals are converted into electrical signals of RGB. By the middle of the camera portion of the matrix circuit, RGB initial converted electrical signal is converted to Y / RY / BY signal. And monitor the process of developing exactly the corresponding matrix circuit matrix circuit and the conversion value of the camera like the inverse of a matrix of this to the original image signal will not be able to reproduce them faithfully rendered. VGA input monitor and restore the image did not specifically consider the issue of the camera, as the monitor on the degree of reduction. Clarity and resolution is the resolution of 800 * 600, in units of pixels, a pixel refers to a point of the display, at a different resolution, the visual size of one pixel is not the same. But the monitor itself has a dot pitch (eg .28) and size (such as 15-inch) description. That 15-inch screen surface is 800 * 600 image points.
Monitor resolution scanning lines are generally used to show how much root or white level line (black and white) number to represent, so most people when talking about the definition monitors, are saying he monitors how much, how many line, so the definition monitors sub-vertical resolution and horizontal resolution. Vertical resolution usually means the number of effective scanning lines of a frame, as our pal system, the number of scan lines per frame is 625.
