I'm getting a constant flickering on my monitor which I believe is due to the refresh rate getting reset to 59 Hz. When I go into monitor settings and change the refresh rate to 60 Hz, then close the dialog and reopen, it's reset back to 59 Hz.

My environment:

  • Windows 7 Enterprise (all updated to the max)
  • nVidia GeForce 8600M GT video adapter
  • Dell 2208WFP ultrasharp monitor

How is it displaying 59Hz in the properties dialog? Whenever I've used the dialog with an LCD screen it always just gives the single option of 60Hz. – ChrisF Feb 8 '11 at 13:15
Advanced Settings (in Screen resolution), Monitor tab, Screen Refresh Rate has 2 options: 59 hertz, 60 hertz. It's wack. – Josh Kodroff Feb 8 '11 at 13:18
The concept of refresh rate in LCD monitors is not the same/relevant as traditional CRT monitors. – Sathya Feb 8 '11 at 13:40
As Sathya says, this number isn't relevant. I see 59Hz on my 27" iMac screen in Windows 7. Check out your screen card drivers, make sure your cable is connected, and there's no interference on the wire. – user3463 Feb 8 '11 at 23:01
Randolph, post that as an answer and I'll accept if it turns out to be the case. – Josh Kodroff Feb 9 '11 at 1:38

This is by design for graphics cards that support TVs. The 59 Hz is actually 59.94 Hz. Please see this Microsoft link on the subject -
