I know that this is a bug that I've spotted for High Sierra, but I'm wondering if anyone has been able to find a fix for this. I'm running a second monitor and for some reason after using the update, my laptop recognizes the monitor for a bit, but after a little bit, it stopped recognizing it at all. I tried different cables (VGA to Thunderbolt & VGA to HDMI) but with no luck. Has anyone else had this issue, and if so, have you had any luck into fixing it?

I'm honestly not sure exactly the issue, but I tried swapping the display cable, from VGA to HDMI back to VGA to Thunderbolt and it's working again really well. Looks like I won't be disconnecting it until the next beta update so I don't have to fiddle around with it for hours again haha.
