1、 Different performance of core components:
CRT monitor adopts a special picture tube, which has stronger color recognition and recognition ability than CRT display, and can more truly reproduce the collected source image.
The LCD monitor uses a special LCD panel with higher physical performance than the same display, such as visual angle, response time, brightness, etc.
2、 Different input signal interfaces:
The monitor inputs AV analog video signal and is compatible with other signal sources, such as VGA and YPbPr;
Generally, the computer monitor only inputs VGA signals of RGB three primary colors for connecting to the computer.
3、 Different resolutions:
CRT monitors can generally reach 625 lines (interlaced) / 1250 lines (line by line), and the number of CRT scanning lines is obviously low.
The resolution of LCD monitor of the same size is equivalent to that of LCD.
4、 Different radiation levels:
CRT monitor generally adopts metal shell to shield electromagnetic radiation, and the plastic shell of CRT display does not strongly suppress radiation.
LCD monitor and display basically do not radiate electromagnetic wave, but LCD monitor is usually an all metal shell, which has a significant effect in shielding external strong electric field interference.
5、 The refresh rate is different: the refresh rate of ordinary color monitor should be below 50Hz (Analog), and the general computer monitor can easily reach 75Hz.
7、 Different components:
The components selected for the monitor are designed with greater current, power consumption, temperature, anti-interference, electric shock ability, redundancy and mean trouble free service time;
Therefore, the stability of the monitor is better.
8、 Color restoration capability:
The monitor will truly reproduce the monitored scene and strive to be true.
The display will render the image, and the image quality is more suitable for viewing, so it is impossible to restore the real monitoring scene.
9、 Size range:
The monitor is used for monitoring purposes, and its size ranges from more than ten inches to hundreds of inches.
Monitors are usually used to connect computers, and the size is mainly within 30 inches
