The resolution itself only indicates the number of distinct pixels that can be displayed on a screen, which affects the sharpness and clarity of the image. It can be controlled by various factors, such as the type of display device, the signal format, the aspect ratio, and the refresh rate.<ref>{{cite web |url=https://www.britannica.com/technology/display-resolution |title=Display resolution |publisher=Encyclopædia Britannica |access-date=2023-04-27}}</ref>
 
Some graphics display resolutions are frequently referenced with a single number (e.g. in "1080p" or "4K"), which represents the number of horizontal or vertical pixels. More generally, any resolution can be expressed as two numbers separated by a multiplication sign (e.g. "1920×1080"), which represent the width and height in pixels.<ref>{{cite web |url=https://www.lifewire.com/what-is-display-resolution-1846849 |title=What Is Display Resolution? |publisher=Lifewire |access-date=2023-04-27}}</ref> Since most screens have a landscape format to accomodateaccommodate the human [[field of view]], the first number for the width (in columns) is larger than the second for the height (in lines), and this conventionally holds true for handheld devices that are predominatly or even exclusively used in portrait orientation.
 
The graphics display resolution is influenced by the aspect ratio, which is the ratio of the width to the height of the display. The aspect ratio determines how the image is scaled and stretched or cropped to fit the screen. The most common aspect ratios for graphics displays are [[4:3 (aspect ratio)|4:3]], [[16:10 aspect ratio|16:10]] (equal to 8:5), [[16:9 aspect ratio|16:9]], and "[[21:9 aspect ratio|21:9]]". The aspect ratio also affects the perceived size of objects on the screen.<ref>{{cite web |url=https://www.pcgamer.com/how-to-calculate-the-optimum-monitor-size-at-any-resolution/ |title=How to calculate the optimum monitor size at any resolution |publisher=PC Gamer |access-date=2023-04-27}}</ref>
