First, the core components have different performance:
The CRT monitor uses a dedicated picture tube that is more capable of recognizing and recognizing color than a CRT display, and can more realistically reproduce the acquired source image.
LCD monitors use a dedicated LCD panel that has higher physical performance than equivalent displays, such as viewing angle, response time, and brightness.
Second, the input signal interface is different:
The monitor inputs AV analog video signals and is compatible with inputting some other signal sources such as VGA, YPbPr;
Computer monitors generally only input VGA signals of RGB three primary colors and serve as a connection computer.
Third, the resolution is different:
CRT monitors typically have up to 625 lines (interlaced) / 1250 (progressive) lines, and the number of CRT scan lines is significantly lower.
The resolution of an LCD monitor of the same size is equivalent to the resolution of a liquid crystal display.
Fourth, the degree of radiation is different:
CRT monitors generally use a metal casing to shield electromagnetic radiation, and CRT monitor plastic casings do not suppress radiation.
LCD monitors and displays basically do not radiate electromagnetic waves, but LCD monitors are generally all-metal enclosures that have a significant effect on shielding external strong electric field interference.
Fifth, the refresh frequency is different: the normal color monitor refresh frequency should be below 50Hz (analog), the general computer monitor is easy to 75hz.
Seven, different components:
The components selected for the monitor are designed for current, power, temperature and immunity to electrical interference, electrical shock and redundancy, and greater trouble-free operation time;
Therefore, the monitor is more stable.
Eight, color reproduction ability:
The monitor will realistically reproduce the scene being monitored and strive to be realistic.
The display will render the image, and the image quality is more suitable for viewing, so the real monitoring scene cannot be restored.
Nine, size range:
Monitors are used for monitoring purposes ranging from a dozen inches to hundreds of inches.
The display is usually used for connecting computers. The size is mainly concentrated within 30 inches.
