Color and your Video Card.
Most color monitors work like TVs: the screen uses red, green, and blue phosphor dots illuminated to different brightness levels to mix colors. Computer monitors pack more dots than a TV, so they look sharper.

Display quality depends on both the monitor and the video adapter card inside your computer. The card controls resolution (detail) and color depth (how many distinct colors). Color depth is measured in bits per pixel—24-bit (often called “true color”) renders about 16.7 million colors for smooth gradients and subtle shading.
