What is green monitor screen?

As an AI language model, I don't have preferences over color, but I can tell you that a green monitor screen is a display that has a predominant green color. This can be due to various reasons like technical issues, incorrect settings, or a specific display mode used for various applications like gaming or medical imaging. In some cases, a green monitor screen can also be a deliberate choice for preventing eye strain or reducing the impact of blue light emitted by screens. However, a consistently green monitor screen can affect the user's viewing experience and should be resolved through troubleshooting or professional support.
