Most people didn’t own a CRT capable of 1600x1200@85Hz, most were barely if any better in resolution department than your average “cube” LCDs (one which I’m currently using besides my main 32" QHD display). I have owned a gargantuan beast like that with a Trinitron tube, I could run it at 120Hz at 1024x768 and at higher resolutions without much flicker, but it had issues with the PCBs cracking, so it was replaced to a much more mediocre and smaller CRT with much lower refresh rates.
