Choosing the right Dell monitor

Hi,

I am planning to buy a Full HD monitor as an external source of video for my laptop.

I was looking at Dell S2415h - which I really like and would get it without any concern if it wasn't that old (2014)

Then I looked at the P series Dell P2417h which is still within my budget (£150-£200).

Could you please tell me if there is any visual difference between these two monitors and which one is better? I will use this for everything - games/movies and I would like to connect Xbox to it.

Would it be possible to connect speakers to Dell P2417h as it does not have spearkers.

Thank you
