Trouble with external display on PowerBook using 10.4

After updating to Tiger, my PowerBook is unable to use an external display as it's only display.

I can use laptop and external display both in side-by-side and mirroring modes without a glitch. But closing the lid of the PowerBook and waking from sleep with external keyboard will make the external display only flicker occasionally and not being able to display anything.. The external display is a brand new hp2035 (20" LCD).

I seem to have the same problem all of the sudden with my IBOOK...what seems to be happening with me is that i plug the adapter into my laptop and the lcd goes blue, then all of the sudden my external display awakens, only to show "no signal input". Troubling, because in 10.4.1 I had no problem. Then my external display goes back to sleep. I went into system prefrences and looked under displays and it reconizes my external ddisplay and says its running fine. The only solution I've found so far is to unplug my external dislpay from the electrical outlet and then plugging it back in. Not convienient at all. Any help from anyone out there?!

Similar issue with my power mac G4. I updated to 10.4.3 and upon restart discovered that my display had dropped acid. I'm experiencing cascading trails when i move or resize windows or applications. The dock will expand but the image remains on screen after the mouse is moved away... I have discovered the following:

The problem is fixable, but the process must be completed every time the computer is powered on or restarted.

The process is as follows:

1. Turn on the computer.

2. IMMEDIATELY go to the dock and open system preferences.

3. Return to the dock, click and hold on system preferences.

4. The text menu of the contents of your system preferences menu will appear.

5. In the text menu, find and click on "displays"

6. The display menu should appear on screen. In this menu, simply double click on the next lowest resolution setting for your display.

7. Your display should reset in the new resolution and work properly. From here you can again reset your display to the higher resolution and carry on as normal.

I hope this helps you all... This is indeed a frustrating bug in the Tiger update. APPLE SOFTWARE DEVELOPERS: FIX THIS PROBLEM ASAP.
