That is screen refresh rate yes. They did the same shit with the Q2 as they did with the Q1, that is they put a higher refresh panel in it then ran it slower. 120hz isn't overclocked, it's the standard refresh of the panel. 

The Q1's panel is 90hz standard, they just run it slower and unfortunately FCC won't let them run it faster, even as an experimental option, because it was certified at 72hz
