I've had dual monitor setup and everything worked fine until one day, the second monitor wouldn't turn on. I reconnected the cords and everything, still no good. Then I rebooted the system a few times and it worked again. The next day the same thing happens, this time reboot doesn't work. I was playing around with the resolution of the 2nd monitor and found that if I changed it to a different resolution, it would magically work again. So this is what happens every time I boot up my computer: Sometimes both monitors work and I am good to go. Sometimes the 2nd monitor does not display and I would either have to 1. reboot or 2. change resolution or 3. a combination of both to make it work. My question is how do I make my 2nd monitor fully functioning like it was before?
