What may cause a monitor to display strange colors?

1. Low refresh rate

2. Increased color depth

3. Improper cable connection

4. Blurred resolution settings

The correct answer is: Improper cable connection

A monitor displaying strange colors can often be attributed to an improper cable connection. When the video cable that connects the monitor to the computer is not securely attached, damaged, or using an incompatible type, it can result in distorted signals being sent to the monitor. This distortion may manifest as unusual or incorrect color output, making it seem like the monitor is malfunctioning when, in fact, it is a problem with the connection. In contrast, options related to refresh rate, color depth, and resolution settings typically do not lead to strange colors in the same way. A low refresh rate might cause flickering or blurriness, but not strange color outputs. Similarly, increased color depth enhances the range of colors that can be displayed but generally does not cause distortion in color representation. Blurred resolution settings may affect sharpness and clarity but do not directly change the colors displayed. Therefore, ensuring that the cable connection is secure and intact is crucial in resolving issues related to strange colors on the monitor.
