No luck. It has something to do with the strange way the drivers are set up, because you can set the internal display to a virtual size of 1024x1280 (and it will actually do it: you end up panning around). I've mentioned on my blog the irritating problem with it not always remembering the screen orientation (apparently this problem isn't limited to the LS800). Even worse, with the external monitor set to extend, it sometimes gives you different rotations on both screens, eventhough it says they are the same! There are also issues with applications getting confused and telling you the screen is too small, particularly in portrait mode. Streets and Trips does it every time, telling you it needs at least a 640x480 screen. Solution: switch to landscape, start it, then switch back to portrait. It works fine.
