If you are going to do a resolution check, that would be a windows function..
Go to Control Panel
Go to Display (and double click)
Go to the settings tab
See what is in the ‘Screen resolution’ portion of the window.
And, if you are brave, change that to whatever your other monitor (or laptop) is.. You should see the same view.
However, Engineer is absolutely correct.. You need to set your widths properly (either absolute or relative) to get this to display properly because everyone out there will have different resolutions and you want your website to be displayed properly to everyone.
