also, almost every high end TV regardless of flavor (lcd, plasma, hd, etc) has a service menu that is hidden. You can do a search on AVSforum.com for your make/model and get the key codes for sneaking into it and changing the settings. BUT, BE VERY VERY VERY careful when doing that, if you screw something up there is rarely an "oooops" key sequence to fix whatever you might have screwed up and you can potentially damage the set.
