Hello everyone
I'm running Windows 11 21H2 build 22000.318
But I don't think my OS is relevant to my question

I have 2 monitors plugged in my PC, the main one and a secondary one. Yesterday I installed a LEDs strip on the back of each monitor, which are plugged in the monitor via regular USB input that's on the back of the monitors. I encountered 2 issues:
1) When I shutdown my PC, the LED strips of the monitors will NOT shut down along with the PC.. they stay up and running. Is there a way to set them to turn off along with the PC?
2) After a couple of minutes from a PC shutdown, the secondary monitor gets into some kinda deep sleep mode and the LED strip that's connected to it DOES shut down along with it, but it happens only with the secondary monitor. The main monitor, although it also enters some sleep mode, does not shut down and its LED strip doesn't shut down either.... Why does that happen? Because it's the main monitor?
Is there a way to set things up so that both monitors get into sleep/off mode along with their LED strip?
I should mention that both of my monitors are the same model of the same manufacturer (Acer), if that's relevant info...

Another question about the LED strips:
The LED strips have a few buttons connected to them (changing color mode etc) but no power switch, which means they're always on. Is there any way to turn the monitor's USB plugin on and off on PC or the only way to turn such a LED strip off is by unplugging the strip's USB cable from the monitor?

Your monitor's USB power is not controlled by the PC. As long as your monitors are plugged in, it will have power. I am just not sure if the power cuts off when your monitor goes to sleep. But I am guessing there is a setting for that on the monitor itself if you want the power to stay on or off. Check your manual. My monitor has a setting to keep the USB power on or off in case I want to use it as a phone charger.

Have you tried unplugging and plugging it back in?

My Dell monitor does this too. Some monitors (like mine) will grey out the setting to turn USB power on /off if certain settings are used, so the USB will stay on.
BTW, It will not do any good to change power management settings for USB in device manager or in power profile settings.
There may be a setting in your UEFI(BIOS) settings, which will do it - but it turns off ALL USB power when shut down.

I just resigned to using the remote that came with the strip... Good luck(y)
