2 monitor setup. But 1 monitor won't fully go to stby mode.

Hey gang,

I got a new monitor and using my old one as a second monitor. The problem is that when Windows 10 activated stby mode. My new monitor won't fully go to sleep. The screen blacks out. But is still on. The Panel backlights a re still on and the power indicator is still lit up and not showing the yellow light in stby. I have to MSI MAG27QRF QD. .

Hi I take it you mean sleep? What happens when only using new monitor and not hooking old one to computer

When it was in single setup. It worked correctly. Just in dual setup. It won't go to sleep mode. But the 2nd monitor does.

What happens if you set displays to sleep before computer goes to sleep

Sorry I mean the 1 monitor won't go to stby. The pc is still on.

Are you able to try different port on monitor or computer

I'll try it when I am able to and give feedback.

I have the same problem as you. I'm currently running asus vg278q hooked on a gpu with a dp port and the sceptre 27inch monitor hooked on the motherboard with a dvi port. So far, I think turn off the pci link state power management definitely stops the black screen when going standby which is what we're having problem with. Give this one a try! Also, is your second monitor hooked into the mobo while your primary one hooked onto your gpu?

No it's in the GPU. I have a Ryzen 3700x. So no onboard gpu.

I see...my bad. :X Have you tried turning off "PCIE Link State Power Management" in the control panel?
