[QUOTE="chscag, post: 725043, member: 46727"] It's very unlikely the monitor has suddenly changed resolutions. It's possible your display preference file(s) have become corrupt. You can try deleting them. (But first before deleting any preference files, make a backup by copying them to another location you can easily recover them from.) Go to: /System/Library/PreferencePanes/Displays.prefPane/Contents/ and delete these two files: info.plist version.plist Note that both files are read only. You'll have to change permissions on them first before the deletion will be allowed. After the files have been deleted restart your MacBook and allow the Dell to be detected again. It should give you the correct resolution. Don't worry about the deleted files as OS X will create new ones. Regards. [/QUOTE]
