I just bought an alienware AW2720HF, and it was working perfrectly I was even able to turn off freesync a couple of times before this happened. I don't know what went wrong it tunred freesync on and off normal, and I did it this time, and now the screen is black. I tried reseting the display settings by looking pictures of the menus, and that didin't work. I have plugged the displayport cable into every other port, and I have unplugged the monitor multiple times. I have turned free-sync on and off I think, over and over again.
