With the introduction of SVGA, multiscan monitors became standard for personal computers supporting a range of resolutions and refresh rates. A typical screen resolution of the late 1990s was 1024x768 at 85&nbsp;Hz<!-- need to find archived personal computer manufacturer product listings and web browser statistics for citation -->, requiring a horizontal scan rate over 85&nbsp;kHz,<ref>{{cite web|title=Modeline Calculator|url=http://www.arachnoid.com/modelines/}}</ref> yet during system boot the [[Power-on self-test|POST]] display and [[operating system]] splash screen would be displayed at the standard VGA 31&nbsp;kHz. Many [[MS-DOS]] and [[Windows]] computer games of the time would also switch to a lower resolution for greater compatibility, more colours, improved performance or to reduce the [[video memory]] required by the [[frame buffer]].
