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.
Installing LGs firmware app and upgrading firmware resolved this initial issue. Now, the monitor will randomly go black while the laptop is in use. Currently, the only solve I've found is to sleep the laptop; when I wake it back up, the monitor will work again for a time.
