From what I can see on Reddit it's just not working for some people - I can't see the difference on my desktop no matter what I try. You need to set the video source lower than your monitor resolution and possible set chrome to high power mode (details here: https://nvidia.custhelp.com/app/answers/detail/a_id/5448 https://nvidia.custhelp.com/app/answers/detail/a_id/5448). Maybe that'll help you - it hasn't for me.
