Monitors not sleeping

[rfemali]

I am running Mageia 9. I have a mother board (Asus Proart Z790) that only had a single HDMI out so I am utilizing a USB-C port for my second display. When the monitors try to go to sleep, I will see the no input message then both go black but trun right back on. I have not been able to get them to stay asleep and any help would be most appreciated. Thanks.

Hi there, your description seems to miss a few details.
So you have your first screen attached via HDMI, and your second screen via USB-C?
Also do you use integrated graphics or a dedicated graphic card ?

When the monitors try to go to sleep, I will see the no input message then both go black but trun right back on.

What's the event when the monitors should go to sleep? After like 15 minutes of idle time, or when your computer goes to standby/hibernate or when ?
Also this does happen for both monitors ?

Please post the output of

Code: Select all

xset -q
lspcidrake -v | grep VGA
