[X4U] Force PB17" external projector/display to 1024x768.

[Robert Tillyard]

Yes, I have done Detect Displays, it gives the same two resolutions.

If I set the PB screen up to 1024x768 then do mirror I get an 800x600 
window in the middle of the screen. The projector is set-up as Auto 
(other options are VGA400, VGA, SVGA and XGA) if I set the projector up 
to SVGA the do detect displays it changes the projector back to Auto.

I thought there might be a way to tell Display Preferences to use a 
resolution it doesn't detect, I thought that an older version of OS X 
had a "Show All" modes option but I can't see that on 10.3.9.

Thanks, Regards, Rob.
