What should be done if a CRT monitor shows signs of image distortion?

To address image distortion in a CRT monitor, checking the connections and cables is the most logical and effective initial step. Poor or loose connections can lead to signal interference or inadequate data transmission, resulting in distorted images. By ensuring that all cables are securely connected and in good condition, many common issues related to image quality can be resolved without needing further intervention.

Other potential solutions, such as resetting the computer or replacing the monitor outright, may be considered later if checking the connections does not resolve the problem. However, these actions might not directly address the root cause of distortion, making connection checks the most effective first step. Ignoring the issue is not advisable, as it could lead to further complications if the problem worsens or leads to permanent damage to the monitor.
