Monitors

The first computer monitors used CRT�s which made the monitor large in size. These monitors used to be monochrome with poor video quality. Later IBM introduced graphic adapter 1981 for color display which actually displayed four colors. But LCD monitor had a great impact on this market. With the advent of LCD in monitor, the size and weight of the monitor decreased and clarity increased but because of its cost it was restricted to laptops. CRT was still popular among general public because of their wider view angle and the lost cost but as the price of LCD decreased they become favorite and slowly stared replacing CRT. Though today LED is replacing the plasma and LCD screen science it has more sharpness and clarity but because of its cost it is still not the highest selling display unit.
