Here's my rundown of what I think the settings do.
Keep in mind that I'm using
Power Saving = On which likely affects the Iris, Brightness/black level, and "Black Corrector" settings.
Advanced Iris - attempts to correct the overall brightness level according to the source. ?
-
Auto2, seems to provide good contrast in a variety of lighting conditions.
- Auto1 a little brighter and more contrast-y than Auto2. Too much black crush in medium-daylight in my room.
- Medium and Low are good in dark conditions, very nice contrast without crushing blacks, but only in dark to very-dark rooms are you going to see all the shadow detail. Again, I have Power Saving = On, if you have that off your results may vary with the Advanced Iris settings.
Color Temperature - standard color temperature control, only who knows what settings correlate to what? I think it's safe to assume either one of the "Warm" settings is NTSC/ATSC standard (6500 K), but which one? I don't know, but I'm using
-
Warm2Sharpness - your basic edge enhancement, I think anywhere from Min to 20 is probably okay, otherwise you're just enhancing the noise/grain. It will depend on your viewing distance (and your eyes) but I'm using
- 10Noise Reduction - some kind of smoothing? I think it's better left
-
OffMPEG Noise Reduction - tries to cure MPEG "macroblocking"? Don't know. I'm using full-bandwidth cable and Blu-ray as my main sources, so macroblocking isn't an overwhelming concern. I leave it
- OffAdvanced settingsBlack Corrector - looks like it tries to darken the black level back to true-black, but at the cost of shadow detail, in my lighting anyway. No thanks, this is turned
- OffGamma - leaving it
- Off
for now, but might play with it some more, this has potential. Gamma can improve contrast and bring out shadow detail, without killing the absolute black level. In other words the picture will be "brighter" and yet blacks won't be gray.... will have to play with this some more.
Clear White - looks like it changes the color temperature of bright whites from "warm" back to "cool".... Yeah,
why do I want this? I do not, so it will remain
- OffColor Space - I don't know exactly what this does but it seems like colors are much better set on
- WideLive Color - amps the color? I think there's plenty of color... Also leave this
-
OffWhite Balance - you need good test equipment to calibrate this properly I think, I leave it all at
0 for now.
Detail Enhancer - some kind of sharpness filter? It seems very mild on
- Low
and brings out a little needed detail, with my 50" screen at 10 feet. I think if you have the larger model and/or sit closer than me, you may see too much grain with this, in which case turn it Off.
Edge Enhancer - more sharpness? No thanks.
-OffVideo OptionsMotion Enhancer - Obviously this is the "
120 hertz so good" feature on these sets

I think most of the time you want it on
- Standard, seems to enhance the motion very nicely, with very few weird edge-artifacts that you sometimes see with High.
- High, can make the picture look amazingly "real" - though almost
too real at times for my taste, and gives you more of those weird edge-motion artifacts.
Motion Naturalizer - inserts black frames? Seems to darken the picture, and sometimes causes unpleasant flicker, at least to my eyes. I leave it
- Off for all sources.
CineMotion - should only be useful for 480i sources and even then only when watching a "movie" - i.e. film source. Since I am usually only watching live sports (60hz material) in SD/480i, and since some people have reported weird effects with ESPN/etc sports-tickers, I leave it
- Off for all sources.
General SettingsPower Saving - lowers the bulb output. Saves power, extends the bulb life (they are $160) and enhances black level? Unless you have your A3000 in a very bright room, and/or have one of the larger 55", 60" models, this is a
no-brainer, set it to
- On
