Pain in the neck warningThis is a great display. It has only one issue and that is a warning box that shows up after starting up my MacBook. It advises me that there is a problem with the pixel count and overlays everything on my screen for a minute, maybe more. It gives me boxes to click but the display is also overlaying the mouse pointer. So I just have to stop work while this useless warning times out. Contacted customer support. No luck. I Al have a few days to return it and still considering that although I do like the display
