However, it's not something we support since you wouldn't be able to fetch the EDIDs from each monitor directly and it's confusing to users since there is only one physical port on the board. > > Hm, shared_ddc is also set with single physical DVI-I connector, at least on > this motherboard. According to your vbios tables there are actually 3 physical connectors on this board, VGA, DVI-D, and DP. If there are only two physical connectors DP and DVI-I port, then the oem set up the connector tables wrong and we need a quirk to properly expose it as single DVI-I connector. > > Could you clarify what EDID do you get with two physical connectors which > share > DDC? Garbage? whichever one happens to go first? It's not really an ideal scenario, but sometimes oems do broken things. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/dri-devel
