I am working off of a laptop and have a second monitor to extend my displays. I have been using this set up for two years now and have not had a problem until last night. It seems that my attached monitor only (main monitor on laptop is not affected) will go black for a few seconds before turning back on and showing my screen. It should be noted that my laptop does not reset the display to place the windows back onto the main screen when this happens but the extended monitor goes black at random. Note that I am running Windows 10 and unable to upgrade to Windows 11 as of now. So far, I have tried the following solutions but still cannot figure this out. Bought brand new chords (HDMI + Adapter) Bought a brand new second monitor (issues happening with both old and new monitor) Checked for updates on all drivers Reinstalled both graphics drivers Rolled back graphics drivers Checked basic settings (sleep/power/screen saver settings) Disabled all services in background apps in "System Configuration" Restarted Windows explorer This means I have spent time replacing and even buying new equipment to get around this issue but cannot seem to figure it out! This is very important since I work at home as well. Please let me know if there is anything else I can possibly do outside of hard resetting the computer (which I cannot do for a few reasons). Thank you!

I use two monitors as an extended desktop outside of a laptop, and today monitor 2 went black again. The last time it happened it somehow worked itself out after half a day. Somehow the solution today was to duplicate the laptop screen onto monitor 2, which at least produced an image. Then I reset monitor 2's settings to once again be an extended part of the desktop, and it stayed that way. Good luck to all!

Thanks for the feedback. Disabling G-Sync didn't fix it for me, though

Just wanted to let you guys know that disabling G-Sync, as someone mentioned earlier in the thread fixed it for me. So I guess it's a driver issue related to G-sync that's causing this, as I've had G-sync on for more than a year and this only started about a month ago.

did you ever find a fix to this I have the same problem

Hello again, I bit the bullet and bought a new monitor and the problem has gone, I used the same HDMI cable and there is no issue, however the power lead does not go directly into the monitor, it has an adapter so that is an anomaly. still using windows 10 still using a DP cable for main monitor and an HDMI for second Good luck everyone else!

Second monitor keeps on temporarily going black at random

Hello again,

- still using windows 10
- still using a DP cable for main monitor and an HDMI for second
Good luck everyone else!
