HP V270 27-inch Monitor Goes to Sleep Randomly

[NickK1]

I am using an HP V270 27-inch monitor as an external monitor for my MacBook Pro, which is running macOS Catalina. 

The monitor is used to extend my laptop screen (it is NOT run as a parallel or replacement display). 

I connect using HDMI (HDMI cable + HDMI to USBC converter). Sometimes, randomly, the monitor display sleeps. I could be watching a movie or even doing work on the monitor and it goes to sleep. I do not know why. I tried turning off the auto sleep option in the monitor settings, etc. but nothing has worked yet. To fix the issue when it happens, I can either put my laptop to sleep and wake it up again, or disconnect and reconnect the monitor by unplugging the hdmi cable quickly. 

Has anyone else encountered this issue / how can I fix it? Thanks.
