Does it make sense to connect another screen?

I have a question and I have a laptop (15.7 inch) which is not that big. Would it be worthwhile to connect a second screen to the laptop? (My laptop has the necessary connections)

I thank you for your answer

That depends on whether you want / need multiple monitors, whether you can afford them, and whether they fit on your table. How are you supposed to help you now? Is it worth it? It really depends on what you want to do?

Yes, thanks anyway
