144-240? This sounds like a Placebo effect. While I'm sure people out there can distinguish between 60 and 120[0], it seems you must be incredibly attuned to visual sensory input (an outlier). It seems you aren't alone, either[1], part of me wants to think this is one big marketing gimmick, but surely people wouldn't buy 240Hz monitors if they couldn't tell a difference? Or is it just a pissing contest for self satisfaction? If I had a few million in the bank, maybe I would also buy a 240Hz monitor -- because why not?
