ByWith the lateintroduction of SVGA 90scards, multiscan monitors had becomebecame standard for personal computers, supporting a range of resolutions and refresh rates. A typical screen resolution of the timelate 1990s was 1024x768 at 85 Hz <!-- need to find archived personal computer manufacturer product listings and web browser statistics for citation -->, requiring a horizontal scan rate over 85 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 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]].
Depending on the design of the monitor, there may be several discrete frequencies supported. For example, a monitor designed for use with CGA, EGA and VGA standards could elect to support 15 kHz, 23 kHz and 31 kHz horizontal scan rates. Alternatively, the monitor may be designed to support a continuous range from 15 kHz to 31 kHz. <!-- links to product manuals for old multisyncs would be useful here, or usenet -->
