Suggestions on monitor for PS4?

Hey guys,

Sorry if this doesn't belong here or has been asked before but I'm trying to find a good monitor I can use to play PS4 on, since I don't have room for a tv currently ☹️ are there any you guys currently use/recommend that aren't crazy expensive? As a side question, what do you do about audio output for monitors that don't have speakers built in?

Thank you!
