No. I am talking about the response time. The refresh rate is separate and completely different and unrelated to the response time. That's why I am talking about values like "1ms" and "2ms". If I were talking about the refresh rate, then I would've been talking about values measured in Hz.
Changing the refresh rate is not going to make any difference - or at least it shouldn't.
So again, find out how to adjust the response time (if it's even possible) of your 60 Hz monitor. You are probably using the highest possible response time right now. I am speaking from experience here.
