My laptop is a Dell Latitude D810 (Windows XP Pro). Just added a Samsung 24" monitor last night. The 24" is now the primary laptop (identify 1) with the toolbar on the desktop. The laptop is the secondary monitor (identify 2). The laptop resolution is messed up now. Even in the little picture it looks like a wide screen and it's not (Display properties, Settings, Drag the monitor icons to match the physical arrangement of your monitors page.) Screen resolution is set to 1024 x 768 and the Color quality is Highest (32) bit. Even when the resolution is changed the screen in the preview window stays on wide screen instead of square (was square before switching the 24" monitor to primary.) I've tried everything I can think of... Please help, thank you!
