Digital Visual Interface (DVI) is the standard interface for a high-performance connection between PCs and flat panel displays, digital CRT displays, projectors, and HDTV. Data is transmitted using the transition minimized differential signaling (TMDS) protocol, providing a digital signal from the PC's graphics subsystem to the display.

Not sure which cable to use?
Check both of the female DVI plugs and look for a label, or check the product documentation to make sure you now what type it is.

Single Link or Dual Link?
Single link cables use one TMDS 165 MHz transmitter, while dual links use two. The dual link effectively doubles the power of transmission and provides an increase of speed and signal quality.  Dual link cable should have no negative effects when used with single link equipment.
Single Link: maximum resolution: 1600 x 1200
                  maximum bandwidth: 165 MHz
Dual Link:   maximum resolution: 2048 x 1536
                  maximum bandwidth: 330 MHz

DVI-I, DVI-D or DVI-A?
-DVI-A (Analog) format is used to carry a DVI signal to an analog display
-DVI-D (Digital) format is used for direct digital connection between source video and digital monitor. This provides a faster, higher-quality image than with analog, because digital format DVI-D eliminates the analog conversion process and improves the connection between source and display.
-DVI-I (Intergraded) combination of DVI-D and DVI-A cables within one cable. DVI-I contains both the digital and analog connections. DVI-I cable cannot connect a Digital output to an analog input or Digital input to an Analog output.
