I understand that through a higher refresh rate, you can 'feel' the higher FPS and mouse movement in games and interactive applications. However, aside from human detection, what impact do higher refresh-rate screens have on the overal computer itself?
For example, if I have a laptop with a 60hz screen and another laptop with the exact same specifications except its screen having a refresh rate of 120hz, what effect would this have on the laptop itself? Does it consume more power? Are any hardware components besides the screen effected by this? Are there any other notable things to be aware of with an increase?
