Ok, so I recently installed a fresh OS (Win 7 64 bit) on my HP Pavilion dv7. I installed all of the updates (via windows update) and obvious drivers (via HP's website). Everything seems to be working fine except for my Acer s231hl accessory monitor. When I navigate to the 'display settings' screen and click 'detect' external display nothing shows up. In the device manager, under 'monitor' all I see is 'generic PnP monitor'. Under 'display adapters' I see 'standard VGA graphics adapter'. So, I figure the I must be missing the graphics driver or the Acer driver (or both). I tried simply using the automatic update driver feature in the device manager with no luck (it says: you have the best driver for your hardware or some such). Next, I tried to manually download both drivers from their respective manufacturers' websites but that didn't seem to help. Am I doing something wrong? Or am I way off? Any tips? Thanks in advance.
