Display always keeps turned on

[Planex]

My displays keeps turned on after i shutdown my PC. I also disabled Sleep-USB-Ports but nothing helped.
Any ideas?

If the motherboard mantains voltage it will stay on, what you can do is set the brightness to zero in lcdsys tab > settings > Brightness when idle.
Keep in mind you need to poweroff/on lcdsysinfo for it take effect after you save this setting
