sapphire RADEON 6870 dual monitor display. problem.

hey guys, i need a hand with my monitoring.

i have just installed a radeon 6870 (which supports 6 monitors. it has 2 hdmi outs, 1 dvi out and 2 mini dvi outs. i want to set up 2 monitors. i currently have 2 hdmi cables going to my lcds, but windows 7 will only register the main monitor. in the display settings there is no second monitor and no option to extend the dekstop across the 2 monitors. the 2nd lcd is showing no signal even though it it plugged in correctly.

any ideas? also i was thinking of getting dvi cables as the images are sharper, but would i have the same problem using the mini dvi outs?

any help is appreciated.

thanks,

james

thanks for the reply. when i had both hdmi outs connected to the card it would only display the main display, and in the settings it wasnt registering the 2nd monitor at all. no option to extend display as i stated previously.

now i have one hdmi out and one dvi out which is working fine. so both monitors are working. but i still need to get both hdmi outs working. i dont want to have one hdmi out and one dvi out as the screens look different in their display(dvi vs hdmi).
