I've started having problems with one of my two monitors in Vista. It starts flickering and then blacks out. If I change the resolution, the monitor starts working again, and then is fine if I change it back to native resolution. It will then work fine until the next session (after a reboot or the energy saver screen save has taken effect). It used to only do this after reboots or once or twice a month. Has anyone experienced anything similar to this? Is it a driver issue or might it some how be video card or Monitor related? Any help would be appreciated as it is starting to get really annoying.
Edit: Monitors are Samsung Synchmaster 245BW's. The graphics card is an Nvidia GeForce 8800 GTS (driver version 181.22)
