Hi I just bought a Samsung XL2370 monitor to hook onto my MBP 15". Problem: the image is pixelated and blurry green. I can slightly see the background though. Screen works fine on a Windows pc. Before I hooked up a 19" on my MBP and that also worked. I tried the menu but no luck. And when I choose the auto adjustment a message appears 'not available'. Anyone the same problem? Or better, a solution? Thx!
