Why do I need to turn my computer monitor on and off multiple times for it to turn on?

Thank you for contact us! I'm Anderson, an Independent Consultant and a Microsoft user like you.

good evening

probably the problem is either the hdmi input/cable, or the monitor/video card itself.

there are many variables, I advise you to look for a technician so that he can tell you the source of the problem.

Turn off ‘mic monitoring’. Just turned on my own headset and had the same issue. When I turned off ‘mic monitoring’ the buzzing went away immediately. Seems like a bug that needs to be fixed, but a work-around at the moment at least.

[quote user="PegasusStrike"]I've since purchased an uninterruptible power supply (UPS) and my monitor stopped having the "flickering" issues when I turned my light or fan off when it's connected to my computer. When I use my Xbox, I plug it into my UPS,
but the monitor still goes dark for 2-3 seconds when I turn my light off or my fan off.[/quote]Is your monitor plugged into a battery-backed UPS outlet or a surge suppressed UPS outlet? Is your UPS showing voltage fluctuations when you turn on/off the light
and fan?

If the monitor is not on a battery-backed UPS outlet, try that first. You should also install whatever monitoring software your UPS came with and see what it's showing when you turn on/off the light and fan.

When I do that nothing comes up on my screen, my monitor has the yellow light on it meaning that its turned off, what it does is turn on, say no signal and turn off.

Hey Diego,

Thanks for your response. Here are the answers to your questions:

When you turn off your Xbox, are you turning off your monitor too or putting it in a Sleep mode?

Ans: Normally, to avoid the annoyance, I have to manually turn off the monitor. The monitor is supposed to go to sleep mode when inactive (without the need to turn off separately), but it would keep coming back on when the Xbox One S is turned off.



Do you have your Xbox plugged into a surge protector or power strip that is shared with your monitor?

Ans: Yes, everything is connected to a power strip.

Have you tested a night where your Xbox is not plugged into the monitor to see if the issue is re-created but with the Xbox unplugged?

Ans: Last night, I removed the HDMI input to the monitor from Xbox One S. This time, the monitor went to sleep after a while. So, it seems the problem indeed is with the console.

Warm regards,
