I have spent hours looking for a solution, but wasn't successful so here goes: I have a 13" MacBook Pro (late 2011) running OS X Lion 10.7.3 -- I have a second monitor (24" NEC EA241WM) connected to the MBP via mini-dvi to vga adapter (not as mirror display, but as a second larger screen). The NEC native resolution is 1920x1200. When I set the display resolution for the NEC to 1920x1200 (had to use SwitchResX), the aspect ratio is off and there is a large black gap on the screen to the left. When I set it to 1680x1050 and pretty much any other resolution, it looks blurry. The monitor works fine with a pc, but is blurry as soon as the mbp is connected to it. I tried to run the MBP in clamshell mode but that didn't make a difference either. Do I need to get a mini-dvi to dvi adapter instead? What am I missing here? Thanks in advance.
