One of my monitors on my dual monitor set up started blinking black for 2-3 seconds randomly

I have an HP Pavilion desktop computer with dual HP 24w monitors.  Both monitors are 2 years old and were barely used last year.   About two weeks ago, one of the monitors started randomly going black.  It will blink black for 2-3 seconds.  I have triple checked that all connections are tight.   Could this be because of a Windows update?  Seemed to start about the same time as a Windows update.     Thank you for any help.

I reviewed your post and I understand that one of the displays is flickering.


Don’t worry, I assure you I will try my best to get this sorted.


I recommend you update the BIOS and the graphics driver from the below link and check if it helps.


Let me know how it goes and you have a great day!
