My monitor appears to have more than just the intermittent black screen issue, its also sometimes unable to wake from sleep…
What I do is, use windows + L to lock my screen, then have the monitor turn off by itself via auto-sleep.
However when waking, sometimes the monitor just stays on but black (can see dim backlight). Sometimes there is a No Signal message, other times there is just nothing.
There appears to be way way too many problems with the firmware… I thought the monitor would be roughly equivalent to the LG 27GP950 since it uses the same panel, but I didn’t think the firmware would be this bad.
