I understand you were having a problem with the monitor after updating to the latest graphics drivers. I apologize for the inconvenience.
After reviewing this matter and I have noticed that you already contacted Intel customer support for assistance. In case you need more assistance or if you have any questions do not hesitate to contact us back.
I'm having the same issue with a Samsung monitor model T27C310LB.
My computer is a DELL Inspiron i15.
Everything was working just fine before Intel Graphics HD 620 auto-updated. It's absolutely frustrating. When I reinstalled a previous version of the driver, it got back to work but somehow I can't disable its auto-updates so the problem keeps coming back.
I am sorry to hear you are experiencing issues with the monitor going blank.
I would like to know what are the graphics drivers version you have been testing on this computer?
Please open new thread and report this problem to the graphics forums
