Get a calibration disk like the free AVS HD709 disk or a commercial one like WoW, Spears & Munsil, and adjust your settings yourself. Because of component tolerances between tv's (even the exact same model and build) using someone else's settings might be very disappointing. However, using borrowed settings might be a good place to start to learn how the different settings interact with each other but you need to take into consideration your own viewing environment because that's an important aspect as well. Do keep in mind that making an accurate adjustment with a calibration disk can definitely improve your pq but it's not calibrating your tv. For that you need to use a light meter and special software.
