For some reason, since we moved, my monitor keeps shutting itself down until it warms up. I can turn the power off and turn it right back on. It's a crap shoot whether or not it'll shut down again in 30 seconds.
All the cables are connected properly. Power is still going to the monitor. This only happens for the first 10 minutes (or so) that the monitor is on. After that it works normally.
Any ideas?
