I have a laptop-to-monitor setup, and after a power outage, the monitor is always flickering on and off (it's really bad at first, then goes down a bit). I have a Samsung SyncMaster 240 monitor.
I'm pretty sure it's just the monitor, because it's fine on the laptop screen. Tried plugging/replugging in everything, and in different sockets, but nothing changes.
I also tried changing the refresh rate of monitor, but the only options were 59/60 HZ and they were about the same.
