LG external displays will no longer stay asleep on 13.4

[ideal.dreams]

I have two LG external monitors connected to my Mac Studio and have been using them with no issue up until the 13.4 update a couple weeks ago. Ever since updating, neither display will remain asleep. Instead, they cycle in a loop where after telling the system to sleep the displays, the screens go blank, followed by a "no input" message, followed by a 1 second sleep before they're turned on again to the "no input" message before going back to sleep for a second. The loop continues until I wake the Mac itself.

Anyone have a fix for this? I was hoping the issue would be resolved in 13.4.1 but the issue is still present after updating.

Same for me, LG 32UN880 and 32UN880P. We're not alone: https://developer.apple.com/forums/thread/730112

My 2nd LG is going black, but the backlight remains on. No flickering or so. A workaround could be to put the Mac manually in to sleep. But that sucks a bit. :/

Cheers. Disappointing that the issue is still present even on the 13.5 beta. It's been months and it doesn't seem like we're any closer to having the issue resolved.

I've resorted to manually turning my displays off when walking away from my Mac for a period of time.

Maybe the fix will be a "feature" included in Sonoma.

Thats the same what I do. btw. I'm running Sonoma. :-/

I think this might be fixed in 14.1. At least, I haven't noticed it today when I've tested. Can anyone else confirm?

Can confirm. IMHO it has been already fixed in 14.0. Anyhow, I'm glad I don't have to turn of my screens anymore. ;-)
