A user reports their monitor has developed a noticeable blue tint. The technician confirms no color settings were changed in the operating system and that features like 'Night Light' are disabled. According to troubleshooting best practices, what is the most logical FIRST step?
Update and reinstall the graphics card driver.
Perform a color calibration using a hardware colorimeter.
Replace the video cable with a known-good one.
Access the monitor's On-Screen Display (OSD) to check its color temperature settings.
Following troubleshooting best practices, the most logical first step is to investigate the simplest and most likely causes. An incorrect color display is often due to the monitor's own configuration. Accessing the On-Screen Display (OSD) to check the color temperature setting (e.g., 'Cool', 'Warm', 'User') is the quickest and least invasive action. This should be done before replacing hardware components like the video cable or performing software actions like reinstalling drivers, which are more time-consuming. Color calibration is an advanced step, not an initial troubleshooting measure for this symptom.
