QVGA (Quarter Video Graphics Array also goes by Quarter VGA or qVGA) is a common name for a LCD screen with 320 × 240 display resolution. QVGA screens are usually used in cell phones, Personal Digital Assistants and some handheld devices. Tthe displays are usually in “portrait” (i.e., the height is greater than the width), as compared to “landscape”) and are said to be 240 × 320.
The name arrives from having a quarter of the 640 × 480 max resolution from the original IBM VGA display, which became an industry standard. QVGA is not a normal mode provided by the VGA BIOS, even if VGA and compatible chipsets allows for a QVGA-sized Mode X.
