If you want to set your basics, I'd suggest getting a calibration disk such as WoW or the the free AVS HD709 disk (there other just as good commercial disks as well). That way you can set your brightness, contrast, sharpness, aspect, color etc following rec.709 standards. That can greatly improve your pq. However, you'll need a blu-ray player to use the disk, at least the free AVS HD709. As far as using someone else's settings, that's not always a good idea because the tolerances from tv to tv can vary by enough that what looks good on one set, looks like crap on another. Your viewing environment also has a lot to do with the overall pq. Keep in mind that a lot of mfrs ship their sets with default settings that don't always look because there isn't just one set of settings that look good to everyone, and tv's in retail outlets are usually set to demo mode with basically all the settings jacked up to grab your attention but not necessarily display the kind of pq that the tv is capable of. If your tv is going thru an avr (Pioneer) it may have picture adjustments affecting the tv. I'd make sure that the Pioneer doesn't have any video adjustments enabled first and then try to adjust your set by eye or use one of the cal disks. It's important that you have all artificial video processing disabled (avr and tv) before making any adjustments. However, you will be limited somewhat by what video controls are available to you. I'm not familiar with your LG so I can't say what you have or don't have.
