I just got a 20" Imac and immediately noticed that the top portion of the screen is significantly darker than the bottom portion and that the bottom portion appeared 'washed out'.
I recalibrated and it helped, but still a significant light to dark gradient.
I googled it and found this is a widespread issue with many iMac owners with the newer 20" screens....
I tried to find a program that would allow me to place an image on top of the desktop as all times to counteract the gradient and I found something that works pretty well. Here is what I did:
1) Download and Install Photostickies - http://photostickies.en.softonic.com/mac
2) Load up Photostickies and go to File/Open and open a gradient image like this one: http://www.ohcello.com/gradiant.jpg
3) In the Main Toolbar, go to 'Control/Inspector/Show Inspector'. Within the inspector, click on the 'Visual' tab and lower the 'Opacity, Shadow, and Fading to either one or two clicks above 0% (your preference... 2 clicks might give your desktop too much of a 'washed out' image...I go with 2 clicks). Uncheck the 'Shadow' box. Then close the Inspector dialog.
4) In the Main Toolbar, go to 'Photostickes/Options' and select 'Ignore Clicks when Inactive'. Within the same 'Options' section, select 'Disable Dragging'
5) Put your mouse anywhere over the gradient (you still should be able to see it) image and right-click. You should get a menu... select 'Level/Top'.
6) From the same right-click menu, select 'Display/Fullscreen'
7) You might not be able to click on anything as the image is 'on top' of everything else. However, all you have to do is 'inactivate' this program (ie pull up another program or window) and it will stay on top of other programs and will not be selected (ie Ignore Clicks, etc).... what I usually do at this point is drag to the corner to activate Expose/Desktop to show the Desktop. I then select any other open windows from the Dock. This pulls up that program but also pulls up the gradient image on top, but inactivated.
***The only time you see the screen without the Gradient is when you activate the 'Desktop' feature from Expose... but once you pull up any other program or screen, the 'Gradient' overlay kicks in....
Let me know if anyone tries this... it works very well for me.

After I did this, I had turned the brightness all the way up and recalibrated to compensate for the 'darker' screen....
