If you know the system specific command, you can invoke it through java with the Runtime class.

Runtime runtime = Runtime.getRuntime();
Process process = runtime.exec("command");


Example use of using Runtime is at:

What version of Windows?

Executing "Control %windir%\\system32\\desk.cpl" (%windir% being the environment variable that tells you where windows is installed) on a recent version of windows, that should pop up the display settings control panel.

Essentially, the answer is no if you are not already a Windows expert. Messing with video and monitor settings is a very complicated and tricky thing and would all need to be done in C/C++ via JNI. See this post: http://www.artima.com/forums/flat.jsp?forum=1&thread=9405

I really think this is much more hassle than it's worth and I can't think of any app that I've installed that does these things for me. They usually say - should run at 1024x768 etc. If you start trying to set it programmatically, you're really opening a can of worms (video, driver and monitor capability, support, compatibility etc).
