Automatic turn off monitor

[MPTraxx]

Quick question...

I have pg279q when I turn off pc monitor still lights or switched to standby mode with orange light led...I must manually turn off monitor (button for turning off)

I want this scenario - when I shutdown pc then also monitor automatically will be turned off without any lights...

I don't know how to I never had these monitora which can not turn off omg... When I sleep don't need that monitor will be lighting...

In bios I have disabled rog effects when pc sleep or is turned off... But monitor can't find this feature.
