That mode looks like the mode from softdevice homepage. http://softdevice.berlios.de/ The gif ( http://www.obsolyte.com/sunFAQ/faq_framebuffer/fbfaq_files/scart.gif ) that is referring a BNC-> RGB-SCART connection is using H-SYNC from VGA (pin 13). My understanding is that composite sync is generated on this H-SYNC pin. Matrox schematics G450->SCART-RGB are using V-SYNC (pin 14) of VGA connector. _______________________________________________ directfb-users mailing list [email protected] http://mail.directfb.org/cgi-bin/mailman/listinfo/directfb-users
