Wavy Monitor Issue

I have a monitor that is hooked up through a switch to both a Windows XP box (and HP computer) and an OpenSUSE box (a Dell).

When I view the XP box, the image on the monitor is perfect. However, when I view the OpenSUSE box, it’s NEVER perfect. No matter how many times I try to configure the monitor (via the monitor’s own buttons) or try “auto-configure” (also a monitor button), the screen is always either wavy or warped in some way. Any idea what might be causing this?

The monitor is HP Pavilion F50.

I think I’ve solved this. I believe it was a refresh-rate issue.

One question though: why are all the settings for display/monitor in so many different places?

  • Refresh Rate is under “Configure Desktop”
  • Monitor Resolution/Colors are under “SaX2”
    And there are more settings under “Configure X11 System”


I have not totally solved this and it’s weird.

  • I finally got it to go away with the settings (on my HP monitor itself) of:

    • Clock = 50
    • Phase = 95

However, when I restarted, it was wavy again! I fiddled with the clock and phase and got it to stop being wavy with:

  • Clock = 47
  • Phase = 95

However, during my time online, it suddenly got wavy again. And this has been corrected now by setting:

  • Clock = 53
  • Phase = 92
