How do you fix a salt and pepper screen?

A salt and pepper screen, characterized by random white and black dots on the display, often indicates a hardware issue with the screen or graphics card. To fix it, start by checking the display connections and reseating cables. If the problem persists, try connecting to an external monitor to determine if the issue lies with the screen or the graphics card. If the external display works fine, consider replacing the screen; if not, the graphics card may need repair or replacement.
