But in general noise reduction is used to clean up ANALOG signal. Even though your TV is 1080p, it is able to receive analog signals and when they're shown in high resolution the noise becomes visible, so 'noise reduction' helps to eliminate that. Nothing to do with your HD problem. For HD the term usually is 'Block noise reduction' or 'Error correction'. In hd the noise appears as blocks or squares on the screen, slow motion, black areas, color dots, etc... but not the snow you mention. And you're right, 1080p should be the most crystal clear today.<br><b>References : </b><br> Different brands define ‘noise reduction’ differently.
