HVGA and WQVGA are two of the many combinations of height and width of graphic display resolutions on computer monitors and display screens of handheld devices such as mobile phones. Such terms have become very common in the form of specifications that are issued whenever a new electronic gadget such as a laptop, computer monitor or a mobile handset is launched in the market. There can be countless combinations of height and width, and some of these have been accepted as industry standards and given acronyms to let people know the dimensions as soon as they see these acronyms.
