I have an extra monitor (LG Flatron E1941) for my iMac that I can adjust to portrait orientation.
The first time I tried to adjust it with the rotation set to 90 deg, it was perfect. However when I chose another resolution, it was minified like this:
The problem is that I can't get it back to be portrait mode and there isn't any option for that. Options are:
1 - 1024x768 2 - 800x600 3 - 800x600 (stretched)
I am running Mac OS X 10.7.4.
How can I reset it back? It was a mess playing around with resolutions.
