What is DVI?
Digital Video Interface (DVI), an uncompressed interface, was developed for the PC industry which was seeking a low-cost, high bandwidth digital connection between PC's and Digital Monitors. DVI keeps data in digital form from the computer to the monitor, virtually eliminating signal loss.
DVI is technology-independent. Essentially, this means that DVI is going to perform properly with any display and graphics card that is DVI compliant. If you buy a DVI monitor, and you want to take advantage of DVI video, make sure that you have a video card that has a DVI port.
All current Samsung monitors that are DVI compatible have DVI-D Single Link input ports. You can use either a DVI-D Single Link cable or a DVI-D Dual Link cable. In terms of quality, picture clarity, etc. it makes no difference which one you use. However, you cannot use a DVI-A (Analog) cable or a DVI-I (Integrated) cable. An example of a DVI port is below:
NOTE : The only exception to the above is the 305T which requires a DVI-D Dual Link cable.
The video card on your PC must be either a DVI-D Single Link output port or a DVI-I Single Link output port.
