Problem with an external monitor on Powebook.

Greetings all,

I have a 1.5Ghz Powerbook and I now have a 20" Dell Widescreen monitor connected into the powerbook via DVI.

When I power the PB on the Dell kicks in and the system works in dual screen mode fine. This is normally fine except that if I want for example to play World or Warcraft solely on the Dell monitor I have to either...

Put the screen in Mirror mode. If I press F7 it does this but it puts the Dell screen into the same res as the pb screen thus making it look awful. It does not seem to be possible then to change the res of the dell display to higher. It limits it to the PB screen max res. Perhaps this is normal?

So my only other choice is to close the powerbook lid so the PB goes into sleep mode and then wake it with the mouse. This then brings the Dell screen up in its full res. If I then open the PB up the screen stays off but I can use the keyboard etc. This is fine, however I cant then switch the PB screen back on without rebooting and so far when I have tried that the PB has just hung forcing me to hold down the power button.

Basically can anyone offer any advice as to using the 2nd screen effetively?

Thanks very much everyone.

That sounds like it might be a plan but I am not sure how to do that.

Can you advise?

Thanks a lot.
