Would this work? I want to get an LCD, but ghosting is the biggest turn off (lot of gaming). Would limiting the fps to 50 for a 20ms display eliminate ghosting? Or 62fps for a 16ms display (assuming its actually getting 16ms)?
no, the ghosting is not a result of out-of-sync frame rates, it is due to the slow response of the pixels to change state after a new signal is sent. Plus most LCDs are set to 60Hz or thereabouts.
