20. Common resolutions are often described using a naming standard - although these standards encompass much more than just resolution size. XGA = ____ x ____.






21. The DMS-59 uses a special cable that ____________into separate video interfaces. For example - the cable might split the signal into two DVI-I connectors - two D-sub connectors - or one DVI-I connector and one D-sub connector.






22. DisplayPort is also an internal video interface used by ____ displays to interface with internal video cards.
