I'm using a BenQ 24' LCD monitor, model FP241W, and when I turned it on this morning, all of a sudden there was a blue rectangle that takes up the top right hand corner of the screen. I've tried connecting the monitor to a different computer, restarting, updating the drivers, nothing has worked. Seems to be on all inputs to, I'm using the DVI. If anyone has any idea why this has randomly occurred I would really appreciate the help!! I would post a screenshot but the rectangle doesnt show up on it. thanks
