I have a laptop and an external monitor connected to it. I switched to single display for an hour and when I switched back to extended display, the monitor suddenly says no signal. I can see it is being detected in the Advanced Display settings so I'm not sure why it's not displaying. I've checked the cables, unplugged them and plugged them back in. I've also tried rebooting my laptop but none of those worked. Is there anything else I can check?
