hu guys,

how do i enable dual monitor with ati 5770?
the 1st lcd is 24' connecting with hdmi cable, while the other is 22" using dvi connector

i have some problems, because when i use a hdmi cable (24") alone, everything is ok,
but when i plug in the 2nd monitor (22", dvi connector), both will be no display,

fyi, im using windows 7

anyone can help me?
tried google, but all are regarded windows 7 how-to,
and ive try every options on windows 7 to enable the dual-monitor, still a no go
