Dell Inspiron 9300 Screen Query.

Hi all. When I originally bought my laptop it had an option for 2 screen resolutions, WXGA+ 1440x900 and WUXGA 1920x1200, and I selected the WXGA+ 1440x900 screen. My screen is now faulty, just through age with the common vertical lines fault, and someone I know told me that I should be able to simply replace it with a compatible WUXGA 1920x1200 screen. Is this true or do I have to replace it with a similar 1440x900 WXGA+ screen? Any advice much appreciated. Thank you.
