|There will only be one DVI connection on the screen/monitor, and that will be 'DVI in'. The cable from there needs to connect to the matching connector on the back of your computer, which will be 'DVI out - though it may not be marked as such. |
If your computer hasn't got a connector the same as the one on the screen you will probably find it has a smaller VGA connector (the middle one in the picture riider has linked to) so you need to either get an adapter for the screen/monitor end, or see if it has a VGA connector as well as DVI.
