Similar to CRT but flat.
Plasmas are fairly color accurate although rarely used for professional applications due to unavailability of professional grade monitors and high cost. They cost substantially more than LCD monitors. Plasmas can be manufactured at sizes larger than LCDs which makes them appropriate for use in public information displays.
Plasma monitors fade over time much like CRTs and can be burned-in by an unchanging image. Some models exhibit video processing delay which will disturb sync between sound and picture. Low air pressure at high altitudes may affect performance of the display.
