The Auto picture mode setting was preset to On, which automatically set the Sony to the Graphics mode when I connected it to my PC. The Custom, Game (reduced lag) and Graphics (reduced lag) Picture modes (color presets) are the most accurate, nearly identical, and allow access to the all of the important settings. Aside from turning off the Auto picture mode and using the Game or Graphics mode and turning off the Adv. contrast enhancer shown below, there's no need to change any other settings.
The Adv. contrast enhancer is turned on by default and causes detail loss, so it's best to turn it off.
