Monitor will not sleep

After the update, my monitor sleep settings do not seem to be effective.


I have my system put my monitor to sleep but keep my drive active after 15 minutes of inactivtiy. The only way to get my monitor to sleep it to manually do it.


Has anyone else run into this?

I have the same problem. Can't seem to figure out the cause.


Also using a late 2015 5k iMac.
