Joe, a user, reports that his neck and back are hurting after being at his desk for the whole day. Which of the following are the possible causes of the problem? (Select TWO).

An non-ergonomic keyboard typically contributes more to wrist and hand issues like carpal tunnel syndrome, rather than primary neck and back pain.

A monitor screen protector guards the screen or reduces glare but has no direct impact on ergonomic comfort related to neck and back pain.

An incorrectly positioned monitor height forces the user to constantly bend or extend their neck, leading to strain and discomfort in the neck and upper back over prolonged periods. Proper monitor height ensures a neutral head and neck posture.

Not using a wrist rest primarily impacts wrist health and can lead to conditions like carpal tunnel syndrome, not general neck and back pain.

A chair that is not properly adjusted to a user's body, lacking adequate lumbar support or set at the wrong height, can cause poor posture and significant strain on the back and neck when sitting for extended durations.
