VGA Connectors

Correct Answer: Verify if the VGA connector is correctly plugged in.

Before checking any other possible issues, first verify if the VGA connector is correctly plugged in, as it might be loose or disconnected. Other options involve unnecessary replacements before checking the basic connection issue.

Correct Answer: Ensure the VGA connection is secure and check the display settings on the computer.

The best answer is to ensure the VGA connection is secure and check the display settings on the computer. A loose or faulty VGA cable can cause a blurry image, so securing the connection properly may resolve the issue. Adjusting the display settings, such as resolution and refresh rate, can also help improve image quality. Replacing the monitor or computer is unnecessary if the issue is with the VGA connection or settings. While installing a graphics card driver could potentially help, it's not the most direct troubleshooting step for a blurry image over VGA.

Correct Answer: Blue

The correct answer is 'Blue'. VGA (Video Graphics Array) connectors on computer equipment are typically color-coded blue. This standardized color coding helps users easily identify and connect VGA cables to the appropriate ports on devices such as monitors, projectors, and computer towers. The other options are incorrect: 'Green with purple stripes' is not a standard color coding for any common computer connector. 'Yellow with black dots' is also not a standard color for computer connectors. 'Red' is typically associated with other types of connectors, such as the right audio channel in RCA connections, but not with VGA. The blue color coding for VGA connectors has been widely adopted in the computer industry to ensure consistency and ease of use when connecting video devices.
