Title: How do I correct the phantom display phenomenon on iBook G4 PowerBook6,7 OS 9.2?
Post by: purakee on December 06, 2017, 07:03:26 PM

I have tried the open firmware trick with "graphic-options" but the display does not change.

Any help is very much appreciated!

Thank you,
Purakee

Find this file:   /Library/Preferences/com.apple.windowserver.plist

Drag it to the trash
Restart

If that doesn't work, holler back.

I have a G4 Alu-Powerbook 15", 1Ghz - the monitor control panel from the G4 unspported install disk shows the proper size of the 2 displays, but can't scale up any of them.
With a different version of control panel (which includes a button named 'default') this button simply sets the display to the correct size.
It had a different name so I just added it, no need to replace. Can't tell the version atm because I'm not at the machine.
ps: it's from System Software 5.3, version 8.6.4

GaryN,

Thank you, but the problem is not with Mac OS X, it is with Mac OS 9.2.2. Sorry, I should have made the title more clear.

hes using an ibook that came shipped with osx tiger with a 7447a type processor and Mobility Radeon 9550 video graphics

im not sure this model has been made to work 100% properly with os9 which is why you are experiencing problems..
did anyone else actually get the 9550 graphics to work properly ?
