get(0,'ScreenSize') can not get right screen size

I want to use scrsz = get(0,'ScreenSize') to get the screenSize. My screen resolution is 1680x1050.I think I should get a value of [ 1 1 1680 1050], but I get a result of [1 251 1280 800]. Do anyone know the problem? I　use matlab 2010a. Thanks

Do you have multiple monitors?

[Sean de Wolski]

Did you change the screen resolution between the last time you started ML and when you called it in this manner?

Do you ever use setappdata(0,'screensize',something) in a function/script?

I do not have multiple monitors. I connect that computer using my laptop. I think it is the reason.

What does this mean: "I connect that computer using my laptop"? This implies that there are TWO computers involved, namely "that computer" and your "laptop". Is that correct, that you have two computers? How are they connected? Or do you just have your one single computer (your laptop) and it is connected to an external monitor?

It has been reported frequently, that some graphics drivers have problems to reply the screen size correctly. This usually concern the multi-monoitor setup and the root's MonitorPositions property. What does this reply:

get(0, 'MonitorPositions')

Have you tried these tools from the FEX: FEX:GetScreenSizeDynamic, FEX: GetMonitorDimension.

[Junwei]

get(0, 'MonitorPositions'), it is give the right result. I think the problem is I remote access the computer through my laptop, whoes resolution is 1280x600. I reinstall ML, then everything is fine.
