I have a new HP Compaq Elite 8300 CMT with Windows 7 Enterprise 64 bit and an AMD Radeon HD 7450 DP graphics card installed. However although my monitor works when connected to the DVI output of the graphics card, under Device manager it is listed as 'Standard VGA adapter'.
I have tried installing the latest driver packages from both AMD and HP and in both cases the AMD Install Manager does not detect the graphics card, it just installs the audio driver and the install manager and says 'installation complete'.
I have been Googling this for a couple of days with no luck, so any help would be greatly appreciated.
