LG 27GL650F-B shows no signal after sleep
I recently purchased an LG 27GL650F-B. After unboxing, setting up, and connecting, the monitor worked fine connected to my macbook pro. However, after leaving it alone for ~45 minutes, I returned, woke the laptop up, and the monitor shows "No Signal". I've restarted everything. I've disconnected and reconnected the monitor. Any thoughts on the root cause and resolution of this problem sincerely appreciated.
