The problem here, according to Soneira, is that most picture transitions involve much smaller, more subtle shades of gray-to-gray transitions, which usually take much longer (3-4 x) to complete. Those response times are far more important to a display’s ability to handle motion blur. But consumers often have no way of knowing which response time is being measured (gray-to-gray or rise-and-fall).
When you’re researching LCD TVs make sure response times are measuring gray-to-gray or GTG. With plasmas you don’t have to worry about response times because they’re more than fast enough.
