Projectors with VGA input

A video projector with only VGA style RGB connector might be a good candidate to try, but a normal PC monitors are out of questions (in SCART the HSYNC frequency is around 15.6 kHz but VGA monitors want atleast 31 kHz). Video projectors can usually handle the HSYNC rate used in normal video (15.6 kHz) without problem even on their VGA connector (check technical data or tech support to make sure of that).

If you display device can handle the picure sent out by SCART and your video source outputs RGB (your normal VCR does not output that, but video games and DVD players might be capable of this) the it might be possible to get nice RGB picture from SCART through VGA connector to the video projector.

What needs to be done is to convert the sync signals used in scart (composite video signal) to the sync signal wanted by VGA connector (TTL level separate sync) with some electronics."

Takže předchozí rady se zesilovačem platily pro "SCART RGB to 4 BNC inputs".

problémem zůstává ta "some electronics..."

Zkusím to nejdřív propojit přímo a jestli to nepůjde (jakože asi ne), tak jsem zas v pytli.
