CRT monitors are characterized by their size, weight, and the physics of how they produce images. Unlike modern LCD monitors, CRT displays are bulkier and heavier due to their use of cathode ray tubes, which require substantial physical space and components. This results in CRT monitors being larger and more cumbersome to work with or transport.

Additionally, CRT monitors produce a significant amount of heat during operation because they rely on electron beams firing inside a vacuum tube to create images, which is an inherently energy-intensive process. The heat generated can lead to warmth in the surrounding air and may even require additional cooling measures in certain environments.

In contrast, LCD monitors are known for their compact design, lightweight structure, and energy efficiency, making them much more practical for everyday use, especially in settings like healthcare where space is often at a premium. Therefore, the notable characteristic of CRT monitors compared to LCD monitors is their larger size, greater weight, and the heat they produce, supporting the selected answer.
