Depends on PEG or Onboard Graphics.

Is there a card installed?

AMT is not the only chipset driver required. There are 3 Chipset Drivers required and 1 Video Driver.

CHIPSET MUST BE DONE BEFORE VIDEO or it wont work at all.

HECI SOL are also required.

The "PCI Serial Port Driver is not actually a Serial Port"

Its the Intel AMT HECI & AMT SOL/LMS Hardware.  

The Current Driver for this works with Windows 7, Vista, XP, 32 and 64 bit.

One Size Fits all.

SpeedStep,

Thanks for the very detailed and helpful reply. The problem is now solved. I reinstalled all of the drivers listed and there was no change until I installed the graphics controller. I actually had a newer version installed already - ver. 7.10 I think - which must not have been compatible. Installing the older driver seems to have done the trick and I can now see the display driver in Device Manager and access all resolutions on this monitor.

Thank you!
