Last time I poked at this was a while ago but it depended on the card
vendor and the abilities of the card. It ranged from outright ignorance
of DDC and user selected modes through automatic response at runtime
(including to 90% rotation of the display)

Without DDC and user information to the contrary all you know is that
640x480 at 60Hz is safe.
