Are you enabling the ability to monitor from your mobile device? If so that is why you get an extra pnp monitor installed
As far as I know, I haven't enabled such feature. Is there a way I could check that? I will have it a look. Thanks for the suggestion. I did get a new Samsung A20e smartphone around February but it never crossed my mind that could be the issue. Also, when news generic pnp-monitor starts showing up my refresh rate goes from original 60Hz to 59Hz and when I check 'ghost' monitor's resolution it shows 640x480 1Hz refresh rate.Thanks again, I will check it out. Also, I read somewhere on this forum that Adrenaline 2020 drivers could be the problem. I am currently using Adrenaline 19.9.3 and so far it has been three days without a issue. Thanks again.
