I have a Dell E6420 (laptop) in company. The Windows device manager uses "Generic PnP Monitor" for the 14" LCD monitor. It only has 1600x900, 1024x768, 800x600, while I was looking for a 1366x768. Google search for Windows 7 driver didn't get any luck. I did find a cab (link), but it seems like not include the monitor driver. Does anyone know where to find the monitor driver? I just need more resolution options.
The dell support page has windows 7 video drivers for the E6420 at this page. or better - go to the Dell support page and enter your service tag (sticker on the bottom of your laptop). There are a few options depending on which LCD panel you have installed and if you are running 32 or 64 bit windows.
If you use the windows default installation driver (from a new installation of win 7) it shows you a lot more resolutions. I'm thinking of extracting that driver from a clean install on another 6420 of a new user, then bringing it to mine because its annoying not to have more resolutions.
