Quote:It's worth mentioning the motion blur measurements of the various different 120 Hz and 144 Hz modes.
Hz does not necessarily always equal motion clarity. Long-time CRT gamers who switched to 120 Hz LCD, they have found CRT 60 fps @ 60 Hz has less motion blur than regular LCD 120 fps @ 120 Hz (due to the stroboscopic nature of CRT flicker). The sample-and-hold issue of LCD displays can cause instant 0ms pixel response displays to have motion blur. Sample-and-hold is also the same reason why sometimes certain OLED's had more motion blur than some LCD's (see Why Do Some OLED's Have Motion Blur? -- particularly the PS Vita) and TFTCentral also talks about the sample-and-hold issue too. Plenty can be found by googling "LCD sample and hold"; it is currently the motion blur weak link on a modern LCD display.
Vega measured the overclocked Catleap 2B IPS to have 40% less motion blur than 60 Hz, while I and Vega measured and confirmed the other LCD's through motion tests, in both PixPerAn app and the Blur Busters Motion Test app (coming soon). Here are the measurements:
baseline - typical 60 Hz LCD (16.7ms continuously-shining frames)
40% less motion blur (1.7x clearer) - 120 Hz IPS (8.33ms + excess streaking between refreshes)
50% less motion blur (2x clearer) - 120 Hz TN (8.33ms continuously-shining frame)
60% less motion blur (2.4x clearer) - 144 Hz TN (6.94ms continuously-shining frame)
85% less motion blur (7x clearer) - 120 Hz LightBoost, set to 100% (2.4ms frame strobe flashes)
92% less motion blur (12x clearer) - 120 Hz LightBoost, set to 10% (1.4ms frame strobe flashes)
So, as you can see, refresh rate does not always equal sharper motion.
