What is a primary disadvantage of CRT monitors?

The primary disadvantage of CRT (Cathode Ray Tube) monitors is their tendency to consume a lot of energy. CRT monitors operate by firing electrons at a phosphorescent screen, which requires a significant amount of power to generate the images displayed. This energy consumption can lead to higher electricity bills and is not as environmentally friendly compared to modern display technologies such as LCD or LED monitors, which are designed to be more energy-efficient.

In the context of the other options, CRT monitors are not considered expensive compared to some newer technologies, especially in the used market; they are also known for their high image quality, particularly in color reproduction and contrast at the time of their peak use. Furthermore, CRT monitors are relatively bulky and heavy, making them less portable compared to lightweight contemporary monitors, further highlighting why energy consumption stands out as a significant disadvantage.
