Which monitor to buy?

I would like to buy a monitor, but I don't have that much knowledge yet. I would like to use it for my PC and xBox, Switch. I only want to spend up to 300 euro approx.

I really like the Acer monitors, have this one: https://www.otto.de/...=682605951

It's not really something special, but it's enough for me.

The Philips 275E1S costs 200 euro in the 27 "wariante and has a resolution of WQHD, good value for money.
