So recently my BenQ T2200HD started acting strange, when i turn my pc and it on, it would stay black, so i unplugged and plugged back in the hdmi cable, i saw a image for a split second then it went black, i kept doing that until the image stayed, i thought it was a hdmi issue, so i replaced the cable but its the same issue, so i tried my laptop and the display had the same issue, now my display wont even work anymore. help!
