I have just replaced my lcd screen but instead of 240 hz I just found out that the one they ordered is 300 hz but it is already installed as my lcd screen. In my razer synapse the laptop screen refreshrate ranges from 60hz to 240 hz but in my refresh rate settings it is only 300hz, is this ok? or do I need to click 240hz in the synapse?if I do that is it safe or will it destroy my display or lcd?
