High-level controlled airspace, in turn, exists from FL180 to FL600 in SDA. In NDA, however, the floor of Class A high-level airspace varies between FL230, in what is referred to as the Northern Control Area, and FL270, in what is referred to as the Arctic Control Areas.
Short for DVI (Digital Visual Interface) Integrated, DVI-I is the connection, or interface used between monitors and computers or home theater systems. DVI-I is used to interface with an LCD or CRT monitor display for digital video output. DVI-I supports both digital and analog. However, it will not use both at the same time. DVI-I detects and chooses digital or analog depending on the connected display. Contrast with DVI-D, which is a digital-only interface and DVI-A which is an analog-only interface.
DVI-I has two sets of signals: a digital signal and an analogue one that is in the same format as VGA. There is also a single and dual link variant of DVI-I, but most cables are dual link. Note that this is something different from the DMS59-Dual DVI adaptor cables used with some video cards.A DVI-VGA cable just hooks up the analogue signals.o, The analog signal is carried over extra wires that is present in a DVI-I cable that is not in a DVI-D Cable.
