HERE is a brief summary of the screen resolution of video monitors for Personal Computers.

The acronyms are shown for each screen resolution. Relationships are shown between the megapixels, aspect ratio, and number of color bits. Monitor megapixel resolution is determined by multiplying the vertical pixels by the horizontal pixels. Aspect ratio indicates the screen rectangle shape.
The approximate year that each monitor resolution became popular is also shown, denoting the evolution of screen resolution history.
