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.

> D:\driver\Win7
> 
> 
> Volume in drive D is Dell E1909WDD

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.
