DELL 2007FWP & GeForce FX 5500 with Windows 7
This has been a quest!
I don't know how long this will last, but after 2 days of struggle I finally have my monitor's native resolution of 1680 x 1050 back. Turn's out (of course) that my display card is way out of date and there are no Windows 7 drivers
– only Vista – and those are very erratic. Finally did find a workaround with a 2 part approach:
Drive Cleaner Pro (for free) from: DCProSetup_15.zip - FTP Mirror Search (Downloads)
which removes all traces of the old drivers
Use this driver
Extract the driver but cancel the install
Mobility Modder from: NVIDIA MobilityModder - HardwareHeaven.com
which modifies the older driver
Then install the driver, and – viola!
So we'll see how it goes...
