What is the 'noise reduction' feature on my HDTV and what does it do?
I have four options for this feature low, mid, high, and off. What setting should I use and why?
Noise is inherent in all electronic circuits and on all electronic signals. If you turn on an amplifier and don't have an input to it, the output will look on an oscilloscope like a bed of grass across the frequency spectrum. This is called noise.
The ratio of the level of the signal to the level of the noise is called the signal-to-noise (S/N) ratio. If the S/N ratio is too low, this causes interference. For an audio signal, this produces excessive hiss in the background. And, for a video signal, this produces graininess of the picture.
If the picture looks grainy and you suspect it might be from video noise, set the noise reduction to "low" and see of that clears the picture up a bit. If so, try the "mid" position and so forth until you get the optimal setting.
Keep in mind that the pictures are so faithfully reproduced by the HD screens these days that turning on the noise reduction filters can actually remove some of the detail from the picture. So, experiment with all of the settings - including "off" - to get the optimum picture quality without sacrificing too much detail.
