So, new to mac and wondering how to properly set up my external monitor. I have a Macbook Pro 15" with a native resolution of 1440x900. My external monitor is a LCD with 1280x1024. It is connected with a DVI cable. When I try to set up my display it wont let me select 1280x1024. Also, when I have my laptop hooked up to my main monitor I would like to be able to close the lid of the laptop without the computer going into stand by. Any suggestions? Thanks!
