Sorry - this got lost in the other threads. The performance will have more lag with a lower refresh rate, as the screen will be updated less often. There has to be some lag, as we have to encode the pixels, send them over USB and then decode them. If you lower the refresh rate, you lower the speed the updates will be sent.
You're best off using 60Hz to keep the updates as quickly as possible and minimise the lag.
