M2 Studio Second Display stays backlit while sleeping

I have a brand new M2 Studio and when I force the machine to sleep (or it goes to sleep on its own after inactivity), both monitors go dark. Then a short while later only the 2nd monitor (a DELL) goes into a backlit blank status. I have tried every setting there is on both the studio and the monitor with no success.



Mac Studio, macOS 14.6

What is the length and speed rating of that USB-C to HDMI cable..?


The latest Mac's do not do well with long poorly made display cables.


I would test a short 1m 4K or better cable with that display.

for examples:

a 1m 4K or better HDMI to HDMI cable.

a 1m 4K or better USB-C to HDMI cable.

a 1m 4K or better USB-C to DisplayPort cable.
