What is NOT a characteristic of CRT monitors?

The statement that CRT monitors are lightweight is not accurate because these types of monitors are generally known for their substantial weight. Cathode Ray Tube (CRT) technology requires large glass tubes and substantial internal components, leading to a heavier overall device. This impact on weight is significant compared to modern display technologies like LCD and LED, which are designed to be thin and lightweight.

The other characteristics noted for CRT monitors reveal their older technology status; they are known to generate a lot of heat during operation due to the electron beam used in displaying images. Additionally, CRT monitors consume a considerable amount of energy compared to newer display technologies, impacting both power bill and environmental considerations. Therefore, stating that CRT monitors are lightweight is indeed not a characteristic that accurately describes them.
