I just did a few tests with java2d for my game project. I want to have a screen-resolution of 320x200 pixels, so I changed the displaymode accordingly. Now Java won't open a Full-Screen window but also no exception is thrown. It works fine when I use 640x480 or any other resolutions. I also checked if the screen mode is supported on my card by iterating through the resulting array of GraphicsDevice.getDisplayModes(), and the 320x200 mode is listed here.
Here is my code:

int screenWidth = 320;
int screenHeight = 200;

GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
GraphicsDevice gd = ge.getDefaultScreenDevice();

DisplayMode displayMode = gd.getDisplayMode();
displayMode = new DisplayMode(screenWidth, screenHeight, displayMode.getBitDepth(), displayMode.getRefreshRate());

Frame frame = new Frame(gd.getDefaultConfiguration());
Window win = new Window(frame);


Any Idea what might be wrong? Thanks!

Graphcis drivers often lie to DirectX.  DirectX will then lie to Java.

Check that the mode you are using is sucessfully settable in the windows dsektop by trying it in video settings..

If it isnt, then its a lie.

Edit: Its also possible your card supports it but your monitor doesnt.  The above check will test that, too !

Got a question about Java and game programming?  Just new to the Java Game Development Community?  Try my FAQ.  Its likely you'll learn something!

Hi Jeff!
Thanks for your answer!
I just set the video mode to 320x200 in the windows/graphic card options successfully, so it still seems that something else is wrong!
I also wrote a game in C++ some time ago on the same machine also using DirectX and 320x200 and everything works fine.
Maybe there is a problem with my graphics-chip and Java? (NVidia GeForce2 MX/MX 400)
