If your SXGA LCD monitor connected via DVI-I with a DVI-D cable is fuzzy at certain spots, what should you do?

Choosing to change the screen resolution to the native resolution of the monitor addresses the issue of a fuzzy display effectively. Each monitor has a specific native resolution that is optimal for its display capabilities, meaning that this is the resolution at which the display is designed to perform best. When a monitor is set to a resolution other than its native one, it may result in blurriness, distortion, or a fuzzy appearance, particularly at certain spots. By adjusting the resolution to match the native settings, visual clarity and sharpness will significantly improve, eliminating any fuzziness.

While adjusting brightness and contrast settings can enhance overall image quality, it won't resolve issues related to improper resolution. Updating the monitor driver may fix compatibility issues with the operating system, but it’s less likely to affect the resolution directly. Changing the cable type from DVI-D to HDMI may not impact display quality either, especially since the DVI-D connection is already providing a digital signal, which is generally better than an analog connection. Thus, changing to the native resolution is the most effective and direct solution for improving the visual clarity of the display.
