What is CRT monitor?

CRT (cathode ray tube) monitor is a type of display device that uses a cathode ray tube to display images. It is a bulky and heavy monitor that was commonly used in older computer systems before the advent of LCD and LED monitors. CRT monitors work by firing electrons at a phosphor-coated screen to create images. They are known for their deep blacks, high contrast ratios, and fast response times, but they are also known for their large size, high power consumption, and potential for eye strain.
