What might cause one corner of an SVGA monitor image to have a consistently purple tint?

Faulty Graphics Card
Data Cable
Power Supply Issues
Monitor Calibration

The correct answer is: Data Cable

A consistently purple tint in one corner of an SVGA monitor image often indicates an issue with the data cable connecting the monitor to the computer. This cable is responsible for transmitting the video signal, and if it is damaged, improperly connected, or has a poor connection, it can lead to color distortion. In the case of a purple tint, this could be due to a failure in the cable that specifically affects the blue signal more than the others, thus altering the overall color balance. While a faulty graphics card could affect the display, it would likely cause more widespread issues rather than isolating the problem to one corner. Power supply issues typically result in overall display problems or complete failure of the monitor, rather than localized color distortion. Monitor calibration generally impacts the image quality holistically rather than creating a physical tint in a specific area. Hence, the condition of the data cable is the most direct explanation for the localized purple tint.
