A technician observes that a monitor is displaying an overly blue hue, despite no changes having been made to the primary color settings within the operating system. Before deducing a hardware failure, what should the technician check FIRST to resolve the issue?
Reinstall the operating system, as it could be causing the color issues.
Replace the video cable as it may be causing the color distortion.
Calibrate the monitor using color calibration software and tools.
Verify and adjust the monitor's color temperature settings if necessary.
When a display shows an incorrect color, such as an overly blue hue, the first step should be to check that the monitor's color temperature settings haven't been altered. If the settings are set to a 'Cool' temperature, it might impart a blue tint to the display; setting it to a more 'Neutral' or 'Warm' setting may rectify the color balance. Checking the color temperature can often be an immediate and simple fix before exploring more complex hardware troubleshooting or calibrations involving color profiles and driver updates.
