Explanation
VGA cables use analog signals transmitted through multiple pins - one pin each for red, green, and blue color channels. If the pin responsible for the red channel is bent, broken, or damaged, the red color signal will not be transmitted, resulting in a display that lacks red hues. Switching to HDMI resolved the issue because HDMI carries a fully digital signal over a different connector, bypassing the damaged VGA pin entirely. The monitor supporting VGA (B) is not the issue since the monitor was displaying an image, just missing red. The PC being configured to output HDMI (C) would mean nothing displays over VGA at all, not a partial color loss. Outdated video drivers (D) would typically affect both outputs equally and are unlikely to cause a single color channel to disappear.
