Resolution - the number of pixels displayed in a horizontal row times the number of pixels displayed in a vertical column. Higher resolution allows for finer details and larger usable display area.

Dot Pitch - The distance between the dots that make up an image. The smaller the dot pitch, sharper the images. Common monitor dot pitches are between 0.25 mm and 0.31 mm.
