How many holes in one shadow mask?

A shadow mask typically has thousands of tiny holes, with the exact number depending on the size and resolution of the display it is designed for. Each hole corresponds to a specific pixel on the screen, allowing electron beams to hit the phosphor coating and produce an image. For example, a standard 27-inch CRT monitor might have around 1 million holes or more. The precise count varies based on the technology and specifications of the display.
