I am buying a HP laptop i.e. Probook 4540s the screen resolution that is by default offered by this machine is 1366 x 768, however I have also chosen to upgrade it and get a 2gb ATI Radeon card in it.
My question with a separate graphics card like above will it allow me to use higher screen resolutions like 1600 or 1920 etc.? Because as per my understanding when you have graphics card all display is handled by it?

If the glass doesn't physically have the pixels, a better video card won't help with resolution - this is similar to the idea that an old tube TV can't show HD content at full resolution, even if you hook up a Bluray player
A better video card may help with frame rate, 3D, and color depth, or with driving an external display (which could be driven at a higher resolution than the native, laptop display).
