As of SDK version 1.7.0 and later, the V4 and V4½ support driving displays through DVI.
Compared to directly attached displays, DVI supports hotplugging: the removal or conection of a display while the system is powered on.
Some new functions have been introduced so the application can properly react to hotplug events.
- gcx:linkState() tells if a display is connected and its state.
- gcx:displayGeometry() allows querying or changing the display resolution.
- gcx:edid() and gcx:backplaneVersion() provide information about the display features.
