    Anybody know howto tweak these "supported resolutions"?
    Funny thing here is that if I choose mirrored mode, I can set any resolution to 21" crt connected via VGA.
    (I'd like to use this 21" as a helping display, since that's the only way to see boot screen in my setup and it's a high quality trinitron still in good shape...)
