My wife has a Mac Book pro 13 inch. I just purchased her a 21 inch Samsung SyncMaster 216bw monitor so she could use it instead of the laptop monitor when at home. The problem is this: The screen only looks good at the highest resolution and at the highest resolution it does not fill the entire monitor. How do I get it to look the same as on the laptop? At the lower resolutions it looks blurry. Thanks!!
