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!

Hey everyone, I had the same issue that started a while back. at first it just happend randomaly when ever plugged in an HDMI and stopped after a few minute. This last week though it totally went dark. I tried most of the reccomendations i saw here like using a powere stabilizer, decreasing my refresh rate and matching it to my additional screen. Nothing seem to work Today i just randomly connected my pc in night light mode and it seems to be working for the past couple of hours and when ever i try to turn night light off my extended screen blacks out. I hope this helps

Hi, I can only speak to my experience. I imagine you should try everything recommended here and elsewhere. In the case of a single monitor, for sure you need to check/swap the cable and the monitor and if that doesn't help, focus on things you can do with your PC. Good luck! jim

I have the same problem but am running windows 11 and it is my main and only display

All, OK. That seems to be a production driver for the particular NVIDIA card flavor you have, Jim. Mine is a different NVIDIA chip. So it seems updating yours to most current fixed the issue for you. I have the most current for me, and still have the issue. But thanks. Its a good lead.

Bob, Actually I think this is the correct update to share... jim All - I had the same issue with two monitor pairs (one at work, one at home) being fed by my Lenovo P15 through TP3 docking stations. Since the same thing happened (monitors would go black for a few seconds and then come back) with two completely different sets of monitors/cables/docking stations it seemed my laptop was the common item. I was on Win 10 and the problem was happening, and then was upgraded to Win 11 and it continued to happen, so it ruled out a specific operating system (but of course both are still Windows). I had run Windows Updates to make sure I had the latest, including Advanced Updates to include all drivers. Nothing helped. I opened a ticket with our support team and one of the techs confirmed everything I had done and then decided to try to update the Nvidia drivers. He used a program called 553.35-quadro-rtx-desktop-notebook-win10-win11-64bit-international-dch-whql . I believe he ran it to update all the drivers and since then the monitors have not gone black once in the past four days. I'm pretty much ready to consider this a permanent fix. BTW - at work both monitors were connected via HDMI. At home one was connected via HDMI and one was connected via DP, but that didn't seem to matter one way or another. So if you have a Nvidia GPU maybe this will give you something else to try...

Second monitor keeps on temporarily going black at random
