Various adapters can be purchased to convert VGA to other connector types. One common variety is a [[Digital Visual Interface|DVI]] to VGA adapter, which is possible because many DVI interfaces also carry [[Digital Visual Interface#Analog|VGA-compatible analog signals]]. Adapting from [[HDMI]] or [[DisplayPort]] to VGA without an active converter is not possible because those connectors don't output analog signals.

For conversions to and from digital formats like HDMI or Displayport, a scan converter is required. VGA outputs to interfaces with different signaling, more complex [[Scan converter|converters]] may be used. Most of them need an external power source to operate and are inherently [[Generation loss|lossy]]. However, many modern displays are still made with multiple inputs including VGA, in which case adapters are not necessary.

VGA can also be adapted to [[SCART]] in some cases, because the signals are electrically compatible if the correct sync rates are set by the host PC. Many modern graphics adapters can modify their signal in software, including refresh rate, sync length, polarity and number of blank lines.  Particular issues include interlace support and the use of the resolution 720×576 in [[PAL countries]]. Under these restrictive conditions, a simple circuit to combine the VGA separate synchronization signals into [[SCART]] composite sync may suffice.<ref>{{cite web |url=http://www.nexusuk.org/projects/vga2scart/ |title=The Nexus: Projects - VGA to SCART Converter |website=Nexusuk.org |date=26 June 2013 |access-date=21 October 2013}}</ref><ref>{{cite web |url=http://www.epanorama.net/circuits/vga2tv/cindex.html |title=VGA to TV converter page |website=Epanorama.net |access-date=21 October 2013}}</ref>
