I have a GeForce GT 640 video card, but by default the screen flickers badly. And if I change the refresh rate to 59 Hz in NVIDIA Control Panel manually, everything is OK. I don't know why.

Change Refresh Rate

Now the problem is, if the system restarts, the refresh rate become 60Hz, then the screen flicker is flickering. I need to change the refresh rate again.

Can I keep the refresh rate to 59 Hz? Or it would be better if the screen doesn't flicker at 60 Hz.

Try setting the refresh rate in Windows' Display control panel instead. –  martineau Oct 28 '12 at 7:27
    
Can't set refresh rate in Windows' Display control panel. It'll become 60 Hz even if I choose 59 Hz. –  EFanZh Oct 28 '12 at 8:01
    
Have you tried to set the refresh rate from the Administrator account? –  memosdp Oct 28 '12 at 8:19
    
memosdp, that's nonsense. The administrator doesn't have any more privileges in that regard than any other user. –  Joey Oct 28 '12 at 10:59
    
@memosdp I don't have an Administrator account. And why would I need an Administrator account to set the refresh rate since I can set from the current account? It just can't keep the refresh rate I set. –  EFanZh Oct 28 '12 at 10:59

Click on the customize button and create a custom resolution at 59 hz. Once you've created the custom resolution then apply it like any other resolution.
