Refresh rate- higher or lower is really low?

Hello,

So I have a pretty low end laptop i5 and HD 4000 but it runs all the games in medium/low settings just fine. I wish to keep all the graphics settings low for smooth performance.

I went to the options section of a game and set all options such as texture, detail and all others to low but got stuck at a point, 2 things were shown:
1360*768 60Hz and 1360*768 40Hz
Can someone please tell me which among the two is the "lower" setting?
 
40 is lower since at 40 your screen will only refresh 40 times a second, but make sure your screen works at that refresh rate.

You can also use a frame rate limiter to lower frame rates(this helps avoid up/down spikes in performance)

I do not think you will see a difference from 40 to 60 because your games may well be running under both those rates any way.
 


Headaches are not an issue with LCD based screens. They do not flicker like CRT's did, which is where you got the headache idea from.

If v-sync is off, your FPS numbers won't change, but your screen will only update its image 40 times per second if set to 40hz, or 60 times a second at 60hz. If you use v-sync, your FPS gets capped at your refresh rate, as it won't allow you to update the screen except between refreshes, and only allow it once.
 

This. If v-sync is off, it doesn't matter which refresh rate you use. It won't affect the game's performance. Just go with the higher (60 Hz) since that means you'll see improved quality if the game should ever exceed 40 fps.

v-sync eliminates tearing at a cost in fps. I like it on, but most people seem to run with it off. Not necessarily for the extra fractional fps, but so they'll see the updated image immediately instead of one or two 60ths of a second later. I don't think it matters, but according to diehard FPSers it does.
