Can anyone confirm on High Sierra if the issue with the Lg Ultrafine display not waking/Mac not sleeping issue has actually been fixed? Thanks!

I fixed my sleep problem with these terminal commands


sudo pmset standby 1
sudo pmset hibernatemode 3

but check this command first to see what your current settings are

sudo pmset -g custom

make note of the standby and hibernate settings, in case you need to revert.

Those are my settings and no issues with the LG UltraFine 5K.

Thanks for this, closest thing I have seen to a fix yet. I'll look into it tonight!

I like the LG 4K monitor very much but I've had a number of problems w/ it when restarting my 2017 iMac. Recently I couldn't get it to come to life after a power failure in the house and sent it in to LG for repair. About $160 later it came back in working condition. The factory put a cryptic note about resetting something in the monitor. A week later another power failure (we have them now and again in these parts) knocked it out. After quite a bit of experimentation I found that Apple's "D" restart option seemed to allow this monitor to reset itself after a try or three. I also had to play around with plugging and unplugging the LG's USB-C plug during start-up. Anyway, long story short it is currently working.
