I got a shiny new EVGA GTX 580 OC last week and has been having a little issue since I got it. Basically I have dual 23-inch Apple Cinema Displays and the second one flickers about once every five seconds.
Very irritating. Anyway here's what I know so far:
- Does not appear to be an issue with the monitor itself as swapping out with my old 8800 GTX and the issue is completely gone.
- Physically swapping the DVI cables attached to the card and the same monitor flickers.
- Switching primary/secondary displays in the Display control panel and the same monitor flickers.
- Refresh rate on both monitors is set to 59 Hertz, I can change it to 60 but it won't save the setting.
- Disabling the "working" monitor and the problem monitor works perfectly, hook up the 'good' monitor again and the problem monitor starts flickering again.
- Some how it fixed itself after a long gaming session (I suspect, anyway) but after a reboot the problem returned again.
- Driver version 266.58
Basically no matter what I do it's always the same monitor flicking even though there appears to be nothing wrong with it. Any ideas?
