I want to buy an AREA-51 m15x notebook, and was wondering what the max refresh rate was? are they all 60? Or can I > the RR by < the Resolution?

The refresh rate is dictated by the monitor and it is genrally not a good idea to fiddle with the settings of laptop screens - if it locks up you cannot unplug it and reset it. It will already be optimised for the machine anyway.

I need atleast 75 , so If the laptop does not meet that, I won't bother and buying it.

I am not familiar with this model (we don't get them in the UK I think) - what does the spec say? If no detail on the refresh rate can you ask someone?
