I have found that, on occasion, if I right click the UltraMon icon in the system tray and select Disable Secondary, then, later, Enable Secondary again, the resolution on the primary monitor is set incorrectly and caused a fuzzy, flickering screen.
In this case, I have two monitors that run at 1920x1200. On enabling the secondary, the resolution of the secondary was set to 1920x1200x60hz, but the resolution of the primary was set to 1921x1200x60hz and it started to fuzz as if there was interference. I got this information from the display info in the monitors OSD.
Changing the resolution in Display Properties to something other than 1920x1200 then changing it back corrected the problem.
As I said, it doesn't always happen but I cannot see what i might be doing differently when it does.

I should add this is 3.0.3 beta on Vista 64 bit with an Nvidia 8800GTS with the latest drivers.

My guess would be an issue with the display driver, UltraMon gets the last used resolution of the disabled monitor from the system, and uses that to re-enable the monitor.

It wasn't the disabled (secondary) monitor that had the incorrect resolution, it was the primary, which remained on all the time.

I read that the wrong way, sorry about that. My guess would still be a display driver issue, when enabling secondary monitors, UltraMon gets the current resolution for enabled monitors, and the previously used resolution for disabled monitors, then enables all monitors using the settings retrieved from the system.
