So I encountered a problem when I turn on my laptop or waking it up from sleep mode my Samsung monitor turn on, shows HDMI 1 in the corner (that's the correct source of video) then it disappears and remains blank. In order to see the video I need to unplug my HDMI cable and plug it in again (It usually starts working when I unplug HDMI from the monitor and not the computer). I tried using a different HDMI cable but the problem remains the same (Also I am using a premium high-speed HDMI cable).
Also, I've updated my GPU drivers but nothing has changed.
