when you say flat screen do you mean tv or computer monitor? a model of the flat screen would help too.
Most likely you will just need to use a vga cable (or possibly s-video) to go from your laptop to your tv/monitor.
oh an once it is hooked up you will probably need to hit your function key (fn) and then something like F4 or F6. There should be a picture a monitor/tv on the fkey. this will change the video output from the laptop screen to whatever you have plug into the vga port.
