I was wondering if this was common, I've got a 5-6 year old Dick Smith
(made by KTV) 720 LCD panel which if I have DSUB and HDMI plugged in
gives no HDMI output at certain resolutions (ie console). If HDMI only
is plugged in I get horrible continuous flashing situation with
console/bios boot displayed normally followed by a completely green
screen.
