Hi all,
I have a LG 27uk650-w monitor which is connected directly by DisplayPort 1.2 to my Dell Optiplex 7060 MFF Display Port 1.2. Everything works fine for display, including 4K (on Catalina 10.15.1 with UHD630 IGPU).
But one issue remains. When the Mac goes to sleep, everything seems ok at first (the screen turns off because there is no more input). However, when I wake it up, the screen turns on a first time, remains on for like 5 seconds, then turns off, and finally comes back on like 5 seconds later!
I have looked at the logs and determined that the LG monitor is sending inappropriate information to the Hackintosh. In fact, the monitor is sending a message through the DP that it was shut down. At wakeup, the monitor sends a message that a new monitor was connected, and the hackintosh interprets this as a hotplug monitor change (and reads EDID again and all that, which wastes like 5 seconds before displaying the screen again).
My question thus: is it possible to patch the hackintosh somehow to disable displayport hotplug detection? I don't need hotplug detection, I have a desktop with the same monitor and it will not change for now.
