Stopwatch And Monitors - Defining Program Parameters

If at all possible, how can my app detect the number, physical location, and size/resolution of monitors in use so as to define the program's parameters? Secondly, I have created a stopwatch variable ("Count"). I can't seem to get it to function properly unless using full seconds. In the following code, I have tried to use a fraction of a second (like .5) and using "count.elapsed.milliseconds = 500" and the program doesn't act like the code is even there...

Code:
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
If count.Elapsed.Seconds = 1 Then
Run()
End If
End Sub
