The SCART connector :
Operates in RGB (all colors have a dedicated wire + one more for sync purpose) for the best possible video quality.
( SCART can also operate in 1 wire mode using NTSC,PAL or SECAM standard but with a huge loss in video quality )
As far as I know , our pi2scart and vga is compliant with all pre made 15Khz retropie distributions available for download
VGA connector :
This Output is compliant with all frequencies handled by your vga monitor .
It's also 100% compliant with Gert VGA / VGA666 adapters
Perfect if you want to use an old CRT VGA monitor or just if your monitor doesn't have an HDMI input .
If your monitor can handle such a frequency , 24Khz EGA signals are also available for pixel perfect EGA arcade racing games.
Connecting both vga and scart outputs at the same time :
As both outputs are wired together it would be theorically possible. But scart monitors need a 15Khz fixed frequency while VGA screens accept generally speaking at least 31Khz . Some VGA screens accept 15Khz frequency but they're quite rare .
