AndySD - thank you for the prompt response - I thought that DVI-D cable will only transmit Digital signals - I also need to transmit analogue signals for which you need either DVI-I cable - both Digital and analogue signals - which is not available at my monitor or perhaps both cables ---- is there any harm in connecting both cables ? I have tried to read up on this but failed to understand it properly - the handbooks on both the pc and the monitor fail to guide you on this point -- jarani
If there is a dvi connection on the pc then use this to connect to the monitor. To take it to its simplist the PC produces digital information, the graphics card then sends this straight to the monitor via DVI or the card converts it to analogue then sends it via that cable. As any signals to the monitor are going through the graphics card you only need the one cable. There are two connectors on the back of the card so you not only have the choice (some monitors disappointingly have only the analogue connection) but you can use the second connection to attach a second monitor.
