If you have 60Hz monitor then you can try to overclock it to 72HZ, NOT 75. I did that and I literally forgot what artifacting is. Then I overclocked it to 96 (24x4) and still no artifacts but more fluid motion.
It was so good that once I saw color/light artifacting I was like WTF was that?! Color artifacting is the only one which still can be seen on 72/96 and other modes like this. When I say color artifacting it's when you see police light blinking from red to blue on the same area for example and other light changing episodes.
TV herz information may e sole marketing. When you hear 600Hz it surely means marketing when they add interpolated HZ to real HZ. What you want to find is real HZ information. PC Monitors usually don't have that marketing BS.
