That all seems strange. I have the September 2002 Consumer Reports in front of me. The Apple 17 inch LCD bested all of the tested models by a wide margin. CR gives ratings of Poor (black dot), Fair (half black dot), Good (clear dot), Very Good (half red dot) and Excellent (red dot). The Apple 17 inch screen was the only one to receive an Excellent rating.
CR commented that the Apple specifically had excellent image quality and a wide viewing angle. The test included nine total screens including the iMac and 7 non-Apple LCD screens, including a Sony which finished 5th out of 9. Also tested were 14 CRTs.
My thought is that something is wrong with your test of the LCD. You may want to try adjusting the settings from the computer, or even resetting the controls back to OEM specs.
