I searched and haven't seen anyone else report this issue so maybe it's just a me thing or maybe it's not a feature that's widely used. I have a hotkey set for the "Turn Off Displays" function and when I press it my screen goes off for a second and comes back on. Before I upgraded to Windows 11 it worked great. As a workaround right now I'm using AutoHotKey and nircmd to get the same functionality and it works great.

Wow. It's been so long since I originally set this up I completely forgot this wasn't a default function. It is in fact a scripted function. I've attached it. Now that I know it's probably some problem with the script in Windows 11 I would attempt to fix it myself but that's really over my head. Any help would be appreciated.

Thanks for testing it. I don't have any issues with idle. I don't ever put my PC to sleep but I tested it and it seemed to work fine. I just use this script as a convenience feature to immediately sleep my screens when I'm done for the night rather than powering them down or waiting for them to time out by idling. It's not a huge deal. If it's working fine on your end it must be some issue with my system. I'll play around with it some more and see if I can come up with anything.
