- resolution
indicates the number of pixels that are displayed per inch for an image
refresh rate
how many times per second the display is able to draw a new image
color depth
is either the number of bits used to indicate the color of a single pixel, or the number of bits used for each color component of a single pixel
Augmented Reality (AR)
is an interactive experience that combines the real world and computer-generated content
