how do you turn off the 120hz feature on the vizio 42″ 1080p LCD tv?
You still get 120hz when the option is set to off, but when On, the option tries to add extra frames to the image and that’s when things look a little bit funky on your screen. You can still benefit from 120hz even when the enhancement stuff is off. If you take a look in your manual for turning of the true motion option, it may help with any problems you are having with your T.V. Motion can be set to Off, Low, Middle and High. You can make changes to this by going to Picture setting in the Menu and scroll down to Expert Control. Once there, scroll down to True Motion option half way down and press right arrow key to change On and Off. Sources: http://www.lcdtvbuyingguide.com/lcdtvreviews/lg-42lgx-review.
