Question : Scart -> to 3RCA -> to VGA

[MorFix]

Hello,
I wanna try connecting my old TV to my computer by 3 cables.
I KNOW I CAN DO IT USING 1 OR 2 CABLES BUT I WANT THE FOLLOWING 3 :

This is a Scart-to-MaleComponent+S-video Cable (Going to TV).

This is a 3RCA-to3RCA Cable (Going to the 2 other cables).

This is a VGA-to-FemaleComponent (Going to Video Card).

1) Should it work without S-video ? I am not planning to use the s-video (altough I have a port in the 1st adapter), and also I want image only-audio isn't needed.


2) Am I able to connect mt TV (Scart) to my speakers ? (with 3.5mm or Component - I have both cables)

Thank You!
