You can connect a display with different specifications but you don't want to mirror the displays. You would want to change to only output to the external. That will allow you to set a mode that wouldn't work for the internal display but will work for your external.

That means I would shut down the laptop display and use the external one right? Could that cause a bad effect on the processor? (Like overheating or alike(?)

No, you wouldn't need to close the lid. What I mean is that by default most laptops will clone or mirror the image to both displays and choose a common mode that both can render. But just like having two monitors on a desktop you can choose to extend the desktop, mirror, or select only one display. You can do this with the Windows display dialogues or use the function keys. I forget which one but it's Fn + F ? key. It's the function key with two squares. The function key cycles through different displays and combinations.
