Display Swapping and Compatibility

Howdy all! Again, I am asking a bizarre question about compatibility with swapping.

Here goes:

So I have this Titanium PowerBook G4 (500Mhz Mercury), and I've been looking on eBay to get a new screen for a good deal. I finally bought one on Monday ($8!!!), and it arrived in the mail yesterday, and I equipped my PowerBook with it right away. I was expecting flaws with it, since it was being sold as is, but I tried it, and boy, it's nice. The only problem is, is that it seems to be the screen from an Onyx PowerBook, and not a Mercury PowerBook like mine. Therefor the actual displayed screen comes out smaller with weird colors bordering the right and bottom sides.

This same thing, I know from my own experimenting, will happen when putting a DVI Titanium PowerBook display on the computer as the graphics card is simply not equipped to recognize such proportions.

The other thing with this display (I believe it's a compatibility issue) is that it will not sleep when you close the screen. It does sleep when you tell it to via the  Apple menu. And it will fall asleep on its own from the Energy Saver settings; and the light at the bottom of the display comes on and oh joy. However, when I close it after having manually put it to sleep, it does not awake when I open it. I have to press keys and whatnot to wake it up.

Additionally, it does not have brightness and darkness controls. Odd! (Even when you go into System Preferences>Displays there is no brightness sliding bar!)

Now, for the most part, I don't really think there's anything I can do about these issues if they are compatibility problems.

I just want to know if there's anything anyone thinks I can do about it. I know there's display resolution software out there, but nothing seems to help it display properly. What do ya think?

Thanks so much!

The only thing I'm knowledgeable about with these symptoms is the sleep issue, so I'll address that one.

There is a small magnet in the display assembly. This magnet triggers another magnet on the frame, which activates the sleep sensor. Apple shifted a small magnet in the display around between models. If you have both display assemblies still, you can see this by putting the display screen down on a non-scratching surface, and moving a small screw around on the rear bezel of the display until the magnet catches it...they're a few inches different!

Unfortunately, these display assemblies are nearly impossible to put back together cleanly once open (the metal bends or waves, and it looks bad). So I don't have any repair suggestions....just explanations :)
