To fix the resolution problem you probably need to install the graphics card drivers first, then install the monitor driver if you want (it should not be necessary). I'd try the E153FP driver - I don't think the missing 'c' will cause any problems.

From the monitor driver readme.txt:

To manually install or update the monitor driver, perform the following steps:

1. Click Start-> Control Panel-> and then double-click Display icon.
2. In the Display Properties window, click the Settings tab, and then click Advanced.
3. Click the Monitor tab, and then click Properties -> Driver tab -> Update Driver.
4. When the Hardware Update Wizard dialog box appears, choose “Install from a list or specific location" and then click NEXT.
5. Check the "Include this location in the search" box.
6. Type the path to the location where the driver files were extracted (most likely "C:\Dell\Drivers\R76072" ) or use the browse button to select the location.
7. Click Next -> Finish to complete the installation.

Alternatively you can just right-click the .inf file and choose 'Install'
