After installing Mavericks, my screen resolution "shrank." The only three options showing up in System Preferences/Display are the following: 1280x800 1152x720 1024x640 Is there a way to change that? I messed with the size of icons and font size on desktop and got it to a point where it is acceptable, but in most "windows" everything is just looking too big. Info about my computer is in the file attached if that is helpful. Thanks for your help!
