SL500 Dual Display Intel Windows 7 64 Bit Professional

Hello,

This may seem really easy but I am strugglisng to set up a dual display between my Lenovo SL500 And my Dell E1911.

The Dell Monitor can reach a display resolution of 1440 x 900 but when i choose that option the display just mirrors the onboard graphics and I get black borders to the right and botton of my monitor.

normally, you just choose scale full screen on the monitor but that option isnt available.

Is there something I am missing at all?

Thanks

Hmmmm... I changed the refresh rate to 75hz and it seems to off worked.

doesnt really make sense but "close enough"

all i need to do now is figure out what the two unknown devices are....

any suggestions?

run Thinkvantage System Update, it will automatically update all the drivers.
