I have a Mac Mini 10.5.8, every time I plug it into my monitor or restart the computer the screen displays different settings. Sometimes it's too big for the screen and sometimes its very bright and washed out. When I go to System Preferences to change the display settings there is no display options icon. I have another Mac Mini that shows the display icon under Hardware in System Preferences. I'm not sure if I somehow deleted the option or if its called something else on this version of Mac Mini but I've tried every setting that made sense and the screen is still different every time. Please help!
