Hmm. Check out the newest Samsung plasma units released this year; the ones I adjusted(I try to adjust out every television in order to get a better idea of it's capability, since the default setting is meaningless) in the store had some extremely high quality images, and impressed me the most, subjectively. Suggestion: disable the DNLe and Noise Reduction on the Samsungs, set color to 'Normal', then adjust contrast, brightness and color saturation, as well as turning sharpness setting down considerably. If any particular color is too strong, you can access the RGB gain, white balance and other fine tune setting by turning the television off, then on the remote: press Mute, then 1, then 8, then 2, then ON. The fine tune/service menu will appear.
