I was using my computer for the while and had this monitor for over a year and as I was using it today, it all of a sudden stopped working and displaying "no signal," I never moved any of the cables so there shouldn't be any disturbance. I tried plugging and unplugging my monitor from gpu to motherboard but nothing still worked. It doesn't register in my nvidia control panel and there still is power that goes into the monitor. I've tried using an hdmi and connecting it and there's still no signal. My computer also doesn't detect the third monitor. Yet this thing still takes in power and shows it has no signal. Why wont it work???
