A '''multisync monitor''' or '''multiscanning monitor''' is a [[Computer display|monitor]] that can properly [[Synchronization|synchronise]] with various [[Horizontal scan rate|horizontal]] and [[Vertical synchronization|vertical]] scan [[Frequency|frequencies]].<ref>{{cite web|title=13 What's the difference between fixed frequency and multisynchronous monitors?|url=http://stason.org/TULARC/pc/video-faq/13-What-s-the-difference-between-fixed-frequency-andmultisynchronous-monitors.html}} 070808 stason.org</ref> In contrast, fixed frequency monitors can only synchronise with a specific horizontal and vertical frequency, limiting their flexibility. Multisync monitors became commonplace during the 1990s as desktop -computer systems began to support an increasing number of display resolutions:

# ~15&nbsp;kHz [[PAL]] and [[NTSC]] based horizontal frequency

# ~31&nbsp;kHz double scan

Fixed -frequency monitors, and multisynchronous monitors that only support a set of frequences, may upon receiving scan frequencies outside design limits overheat their transformers. This is especially true for vertical scanrate.<!-- This is common knowledge for people in the field -->

Some monitors have protection circuits that will block invalid scan frequencies.
