A:Answer I have the same problem! After trying several USB to USB from Amazon, I took the AOC monitor to a Best Buy store and the guy that helped me tried several cables he thoDavidught should work and plugged them into two different laptops. No luck. he said my monitor must be bad, so I bought a new monitor. By the time I got home, I realized I should just try the cable from the new one. It worked, as I suspected. I am searching for another cable so I can return the machine. Anyone??
