Me too. I'm also really sensitive to PWM. I tried using 85Hz on my VGA monitor but the higher signal bandwidth and cheap hardware made the video noticeably blurrier. 70 wasn't a great compromise either. Since TFTs came I was bothered a lot less by it because the lack of flicker (though some 4 bit cheap TN LCDs still had it with some colours)
