Once you have that external monitor hooked up you should have the ability to set the resolution to any size that the display supports. You may need to uncheck "show only compatible modes" if the monitor profile is generic and the correct mode is not shown.

Hello Rob,
if it only was that easy ;-)
I already tried this, but the mode is not listed. I also tried several different monitor drivers. I suspect these "drivers" list the video mode ranges of the monitors.
Currently it is set to "Plug and Play Monitor".
Is there any way to find out whether and if yes which EDID information the display sends?

Have you tried downloading the manufacturer's recommended monitor driver/profile from their web site and see if that helps? In many cases you don't have to go through that step, but if nothing else is working then maybe it would be worth checking. Also make sure your display drivers are up to date.

If you've already tried that then I'm not sure what else to suggest. You're really facing more of a Windows problem than a Dell-specific problem, so you might find additional help on a MS newsgroup or mailing list. See nntp://msnews.microsoft.com for newsgroups.

I installed the newest NVIDIA driver.
NVIDIA does not offer any enduser support but refer to vendor support...
And I am not sure if microsoft can help.

Make sure you are using the latest display driver recommended by the Dell support web site for your model. Don't install a display driver from the display adapter manufacturer. For the monitor profile/driver, you do want to go to the manufacturer web site to get the right one.

Microsoft, the company, is not likely to be any help. The Microsoft Windows-oriented newsgroups at the server I offered are likely to be a help because there are other users there discussing Windows problems such as changing your monitor resolution. As I was trying to say, your real problem has more to do with "how can I get Windows to set the resolution in my situation" than "my Dell computer has a video problem". While both are true, you're likely to be getting your problem in front of hundreds more users on the MS newsgroups because this Dell forum is pretty lightly traveled.
