With the latest d-r-t my grub cmdline option video=1280x720 at 50 no longer works (RS780, output to LCD TV via HDMI). The fbcon apparently is enabled, but the TV doen't get a displayable picture anymore. Booting with d-r-t from 4 weeks ago works and correctly uses the EDID reported 1280x720 at 50 mode.
Does anyone know what might have happened to the video= code? I also tried video=1280x720R at 50, but that didn't work either. X works fine though. Thanks Marius
