I don't think they go low enough to reduce the DP lane count... maybe there's just a mismatch between their hard coded panel timings and the ones reported by the EDID. Not sure which to trust... Kristian can you post the timings you see here? Both the BIOS timings and the EDID ones? So I'm stuck here too, I think it's a rare case though. -- Jesse Barnes, Intel Open Source Technology Center _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
