Hi, I have this 15" MBP and an external 26" TFT
It has OSX and WinXP
WinXP offers this really nice option to use 1 screen only, so when connected only the 26" displays in 1920x1600
OSX however can't shut down the MBP screen so it's either a 26" in mirrormode (with 1440x900 looks horrible) or two screens next to each other. It happens a lot that a new window opens on the MBP instead of on the 26" so I can't see it.
How can I shut down the mainscreen?
