Screen spanning & full screen

[nichos]

Hi all, I just got a Dell 1905FP LCD monitor, which is 1280x1024 native. I've installed the screen spanning hack. I have the resolution set to 1280x1024 but I get a big black boarder around the screen. That is, it doesn't look fullscreen. When I go back down to 1024x768 it's fullscreen. I'm not using mirroring. Anyway to fix this? Thanks,
Nick

How about has anyone used the screen spanning hack, and had the same problem? Are there no answers because nobody knows, or I'm missing somethign obvious here?
Thanks again

When you put it on 1280x1024, my LCD does the black border too. Then I have this button called Auto Adjust, which, when pressed, adjusts itself perfectly. Have a button like that?

thanks for the reply. Yeah, I have a button like that, but it doesn't fix this. It does auto adjust, but doesn't remove the big border. Any other ideas?
