CRTMonitore
CRTMonitor refers to a Cathode Ray Tube monitor, an older type of display technology that was prevalent before the widespread adoption of LCD and LED flat-panel displays. These monitors work by firing a beam of electrons from an electron gun at the back of the screen. This beam is deflected by magnetic fields, allowing it to scan across the phosphor-coated inner surface of the glass tube. When the electrons strike the phosphors, they emit light, creating the image that is visible to the user.
The image quality of CRT monitors is characterized by a high refresh rate and excellent color reproduction.
The technology behind CRT monitors has largely been superseded by newer display technologies like Liquid Crystal
