Explanation
Green dots that appear constantly and do not change regardless of what is displayed on screen are classic symptoms of stuck or dead pixels - a manufacturing defect in the LCD panel itself. Because the dots are present at all times and the monitor is brand new, the fault is in the display hardware. A loose video cable typically causes flickering, color distortion, or a completely lost signal - not fixed colored dots. A faulty video card would usually cause widespread display corruption across the entire image, not isolated fixed-color points. Outdated video drivers may cause rendering issues or artifacts, but fixed physical dots independent of the displayed image point directly to a physical pixel defect in the monitor.
