Hey, just wondering if anybody has the same issue. Used the 1680x1050 resolution from the beginning of my MBP. No problem whatsoever. However, when switching to higher 1920x1200 I realised that startup loading bar after entering the password freaks out. The screen goes black and the only bar is visible. When switching to lower resolution, problem disappears, so it is only caused by the 1920x1200 settings. Thoughts?
