Which is major part of monitor. The CRT is linked with a phosphorous material that glows when it is struck by a stream of electrons.
  • 5. They operate at any resolution ratio without the need for recalling the image. CRT runs at the highest pixel resolutions generally available. CRT have fast response times and no motion artifacts. CRT are less expensive than comparable displays using other display technologies. CRT produces the very best color and gray-scale and are the reference standard for all professional calibrations.
  • 6. All color CRT produces annoying moiré patterns. Subject to geometric distortion and screen regulation problems. Some CRT have a rounded spherical shape screen. They are large, heavy and bulky.
