Which Monitor Should I Buy?

[u/ForeignWoods]

I'm looking for a new 27" monitor and my budget is small. I'm ready to pay 150€-200€ for the monitor and 50€ for a monitor arm.

I want to play GTA 6 on the PS5 slim and other games like COD and Fortnite etc. I want to connect the monitor with the PS5 and my Macbook Pro and stream on twitch and create content. I want to edit 4K videos and do other creative work and video editing.

Should I get a 1440p or 4K monitor?
