Default What is DNR supposed to do?

Like many LCD HDTVs, my Samsung 52A750 has a "Dolby Noise Reduction" option in the setup menus. It can be set, turned off, or set at "Auto." Most people advise just turning it off, saying it's obsolete technology. One person on here said DNR is a "detail killer."

I've played with it and experimented with it until I was blue in the face, and I can not for the LIFE of me get it to do anything or have any visible effect, no matter what's on the screen. Just what is it supposed to do? Is there anything I can do on the TV to CAUSE it to have an effect, just so I can see what (if anything) it does?

Right now it looks like the winner of the Most Useless Feature prize...

DNR is intended to eliminate "mosquito noise" and "ringing" that you see around images. This noise is a by-product of the source (cable, sat, FIOS, DVD, Blu Ray). But with a proper signal you shouldn't have much noise on 1080i or 1080p sources. Where you will see this is on SD (480i and p) sources. But the fact is that those are garbage signals to begin with so the expectations should not be high. So, DNR helps on SD but makes HD a bit softer

So, the trade-off is: do you want to try to improve an already bad signal or do you want to degrade your best signal (HD). For me, I would leave the DNR off as I don't want to degrade my best signal to try to halp a poor signal

DNR does not stand for Dolby Noise Reduction. It stands for Digital Noise Reduction. Omeletpant's description is correct.

OTOH, Dolby Noise Reduction was a noise reduction system used in analogue recording/playback systems to mask the hiss that is always added in magnetic analogue recording processes.
