Hi, I have a macbook 13" that is doing some weird things in regards to HD resolutions. It's connected to a samsung syncmaster 2350 and the native res on this panel is 1920x1080p via VGA. To make things easier I recently upgraded it to snow leopard and downloaded all relevant fixes. After the upgrade it detected the res of the panel and everything was wonderful and working perfectly. I come in the next day and the screen upon wakeup is looking weird and blurry. I check the res options and sure enough in it's wisdom it has decided that 1920x1080 is no longer a selectable resolution and 1920x1440 is the only via option...which works but looks like rubbish. Any idea on how to force the res to stick and for the OS to not be typically Mac and "helpful" and stop changing things without user input? And no I am not interested in buying switchres or any other of those ridiculous shareware apps when the mac CAN detect and support the right res..I just want it to stop changing once set.
