I have a new Windows 7 (32-bit) Dell Latitude E6410 laptop, and a new Dell E1909WDD Flat Panel Monitor.
The only way to connect to the monitor is via an integrated DisplayPort cable. http://en.wikipedia.org/wiki/DisplayPort
There is no VGA or other alternative. The monitor supports DisplayPort only.
The problem is that the monitor will not allow any other resolution than 640x480.
In Windows 7 Control Panel | Display | Screen Resolution, I can detect the E1909WDD as display #2, but the resolution drop-down is stuck at 640 x 480 - the resolution drop-down control is disabled.
In Control Panel | Devices and Printers, the monitor is showing as "Generic Non-PnP Monitor". In the monitor's hardware properties | Driver Details it shows:
Driver Provider: Microsoft
Driver Date: 21/06/2006
Driver Version: 6.1.7600.16385
The CD which came in the box contains driver files as follows.
Volume in drive D is Dell E1909WDD Volume Serial Number is 2C1F-9E5E

When I try to update the drivers for the monitor, pointing at D:\driver\Win7, Windows 7 tells me the following:
The best driver for your device is already installed Windows has determined the driver software for your device is up to date.
I'm grateful for any help you can provide.
