What kind of graphic card are you using?

You can obtain this information by using the following command on the command line terminal:

sudo lshw -C display

Firstly you can pretty much forget using windows drivers (setup.exe) for any device in your Dell under Linux. Linux does not use Windows drivers. (There is an exception to this, but not for displays).

To reconfigure the display use go to Applications --> Accessories --> Terminal then run the following command:-

sudo dpkg-reconfigure xserver-xorg

It will ask a number of questions - most of which you can leave as the defaults, but you might want to (when it asks) add in the screen resolutions that you know your display supports. You can run that command a number of times until you get it right.

Each time you run the command you will need to restart X (the graphical display) for the change to take effect, you can do that with this command:-

sudo /etc/init.d/gdm restart

Note: Sometimes the settings for the refresh rate are wrong when you reconfigure, so make sure you know what the values for vertical and horizontal refresh rate are. They should be detailed in your manual. The following values are probably okay though:-

    HorizSync 30-61
    VertRefresh 56-76

You only get prompted for these during reconfiguration if you choose something other than "simple" when configuring the display. Alternatively you can edit /etc/X11/xorg.conf directly to maintain these values with the following command:-

sudo gedit /etc/X11/xorg.conf

Look for HorizSync and VertRefresh. Again every time you change xorg.conf either by reconfiguring or manually editing you need to restart X for the change to take effect.

Come back to us if that doesn't help.

The possible video modes are listed in the xorg.conf file (/etc/X11xorg.conf) under the section modes. The possible resolutions are under the section screens.

In your configuration tool inside Gnome or KDE (or any other windows manager), you can only select from those options (sometimes limited in order to protect the monitor if you choose one there).

You should make sure that you never select (or even better, have anything inside the xorg.conf file) that in modes shows frequencies that would destroy your monitor (screen). That's why it can be dangerous to play with those values.

If you have no lines for the resolution that you want to use in the xorg.conf file, you cannot choose it.

If the values are are not accepted by the video card, you will see error message in the file /var/log/Xorg.0.log

So first I would look that the resolution and refresh frequency is existing in xorg.conf, and there are no errors for that praticular mode/screen in the log file.

If this is the case, go to the tool that allows you to set the resolution (In KDE it is KMenu->System Settings->Hardware-Display, Gnome has a similar tool). There you might have to make sure that you have configured the video card and Monitor correctly (at least in KDE you have this option). With the right combination you should see all the possible resolutions/refresh rates that you can choose. You might need to go in administrator mode in order to change the settings (In KDE).
