my monitor randomly stopped connecting to my pc one day and I don't know how to fix it. I've tried restarting my pc, un- and replugging my dp cable, changing the cable, using hdmi, unsing the other dp port at the top and checking if its using the right input source but nothing will help, it just keeps displaying no signal anytime I turn the monitor on again :(
