There are two voltage-controlled pins in the SCART standard:

Pin 8 --> 0-2V = TV Mode
           5-8V = Wide screen
           9.5V-12V = AV Mode (aka external input)

(You want AV mode)

Pin 16 --> 0-0.4V = Composite video
            1-3V = RGB video

(You want RGB)

Not all displays fully implement this, but several of my units here do 
require that both lines be conditioned appropriately.
