Hi

I purchased a brand new monitor S2421H in August 2022 and have been using it since. I use it as a secondary display for my office work through a Dell Latitude laptop. It was working all fine, but since last few days the screen gets blank intermittently for 1/2 seconds and then comes back. There is no pattern and it happens randomly. 

Point to note is that when I connect it with my personal laptop (which is again a Dell laptop), it works without any issue.

I referred to a previous post where it was suggested to turn off the Input Source "Auto" which I did. But it is still not working.

I got my work laptop checked by IT Helpdesk and it has the latest display driver,  so not sure what can suddenly cause this issue.

I have checked the HDMI cable, power cable and no issue with those.

If anyone has faced such situation or has any clue, please share input.

Thanks
