Which statement about monitor placement is true?

• A. Computer monitors should be placed with the top line at or below eye level.
• B. Monitors should be directly in front of or facing windows.
• C. Monitors should be placed more than two arm lengths away.
• D. All of the above

Answer: (A)

Placing the monitor so the top of the screen sits at or slightly below eye level helps keep the neck in a neutral, comfortable position during long computer work. When the screen is at or just below eye level, you can look slightly downward without tilting your head up or down, which reduces neck strain and makes it easier to maintain good posture over time. This height also supports a natural line of sight that centers the screen in your field of view, helping you read text with less effort and fewer headaches.

Avoid putting the monitor directly facing a window, because glare and reflections from natural light can wash out the screen and force you to adjust your posture or squint, leading to eye strain and neck tensing. Even if the height is good, glare makes this setup uncomfortable.

Distance matters as well: about an arm’s length is a comfortable starting point for many users. Being significantly farther away—more than two arm lengths—can cause you to lean forward or strain to read, which again increases neck and eye muscle work.

So the statement about keeping the top of the monitor at or below eye level reflects the best ergonomic practice, while the other points introduce conditions that can cause discomfort or strain.
