Monitor endlessly blinking on and off

[sneakysquid09]

I purchased an HP monitor in June 2020 and have been having problems off and on since - but it's recently come to such a head that the monitor has been essentially rendered useless. I have plugged it into multiple computers with the same outcome - after 5-10 minutes the monitor goes black and blinks on and off repeatedly until I turn it off. The only resolution I've found is to jam enough crap under the HDMI cable that's plugged into the monitor to prevent it from blinking *as* frequently. So, the hack job I did is essentially forcing the cable up and in? I have no idea.

I recognize this is a bit of boomer engineering, but at the moment it's the best I can do.

Regrettably, I ignored the reviews on Amazon etc. that alluded to this very problem. I checked HP's website for driver updates, and the only ones I could find were from 2018, presumably not relevant now? I really like this monitor otherwise. It's the perfect size, the base is stable and doesn't take up a tremendous amount of space, and it's a decent price - but this experience has put me off HP monitors unfortunately.
