Why each option
A green tint on a VGA display indicates one or more color signal pins are not making proper contact, which is characteristic of a loose cable connection.
Outdated video drivers affect rendering and resolution but do not selectively drop a specific color channel causing a single-color tint.
VGA cables carry separate analog signals for red, green, and blue on individual pins. When the cable is loose, one or more signal pins lose contact - if the red and/or blue pins lose contact while green remains intact, the display shows a persistent green tint. This is a classic symptom of a physically loose or partially connected VGA cable.
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.
A failing video card would typically cause artifacts, no signal, or total display failure across all colors, not a selective green tint.
