Hi freakie,
This is what I got from an Amazon reviewer:
"Spend some time tinkering with the picture settings. After a while I got things looking amazing. I keep backlight at 30 and brightness at 20. Contrast at 60. Noise reduction off. Color at 30. Tint 0, Sharpness at 5 and didn't even bother messing with color hues and such. Temperature is medium and picture mode Standard."
Please report back if this helped. I'm planing to get the 47L2400 myself.
