Common mistakes.

- C. A faulty monitor would more likely produce symptoms like flickering, dead pixels, or total display failure, not a consistent single-color tint tied to signal pins.
- D. A failing video card would typically cause artifacts, no signal, or total display failure across all colors, not a selective green tint.
