Parallel displays often specify a few ms delay after the voltage supply is stable and before pixel data should be driven on the bus (.delay.prepare), as well as afterwards, before activating the backlight (.delay.enable). regards Philipp _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
