Refresh rates, CPU use, and panel brightness

Can someone explain the impact of refresh rates to me? If I run at 60 Hz with a divider of 1, I wind up with about 40K less memory than if I do a rate of 180 and a divider of 3.

Color depth I can get, but why does a higher refresh rate take more memory? And is faster better in terms of brightness?


No, it’s not. In the ideal case, the brightness does not depend on the refresh rate, in the non-ideal case it will rather decrease as the frequency increases.
