for anyone who has some experience or expertiese on this subject please help. I am trying to tap into my car navigation system screen which is a 7'' rgbs monitory. has rgb and sync. i have a vga or svideo output on my laptop i want to connect. i have a vga to rgb calbe, not rgbs.
from my research i should be able to use sync on green method for the sync.
i have tried this but possibly my wireing is wrong. any ideas.. i dont know if i necessarily need a circuit for this, and dont want to spend $500 on a unit to convert the signal. my diagram is as follows
pc--vga------R------R------------ Monitor
pc--vga------G-----G+S---------- Monitor (i dont know if this is correct??)
pc--vga------B------B------------ Monitor
all i get is black screen with lines..
