Hi Audrey,

Unfortunately the built in video cards in most laptops are not suitable for use with the video output from the KN7000 as they have no provision for a composite video input. The video signal from the KN7000 uses a single pin coaxial connector whereas the computer video requires a multi pin connector. Some computers and/or monitors are fitted with the required connector and have the capability to accept the video signal from the KN but this is not generally the case. If the computer monitor has the additional required video connector the output fron the KN can be connected directly to the monitor.
The alternative and by far the simplest solution is to connect the the video output from the KN to tha video connector of an AV input on your television making sure that your television is set to view the appropriate video input. Also make sure that the video output from the KN is set for the appropriate television system (PAL for the UK - NTSC for USA). Most recent televisons are fitted with one or more sets of AV inputs, a set of 3 coaxial connectors and the video connector is generally colour coded yellow. It is not necessary to have a connection to the other two connectors in the set. These are the audio input connectors, generally colour coded red and white.
In Europe some televisions sets are only fitted with one or more multi-pin Scart connectors for the various input and output signals. In this case it is possible to buy a suitable adapter from you local supplier.
Hope this helps.
