I'm in the market for an external monitor for my Macbook M1 and wanted some advice on what I should get. I pretty much only code, read pdfs and webpages, and watch videos (not movies really) on my laptop, so these would be the use cases. I'm trying not to break the bank here so I was looking at some budget options. The Macbook has USB-C so I would be looking for a monitor with that, but my main question is regarding resolution. Do I really need a 4K monitor for my use cases? I'd be interested in hearing people's experiences with 4K versus without — I've never had one but I'm wondering if now is the time to splurge and get it? Will the difference be very noticeable if I'm primarily looking at text?

My first place option right now is this one from Asus, so I'm curious if the brand is reliable as well. I don't think I've ever had an Asus product. If I were to splurge and get a 4K monitor I would probably get this Dell, but at $400 its a bit more than I was hoping to spend. But I also don't want to get a monitor that I immediately want to upgrade. Curious what other people's thoughts and experiences have been.

EDIT: See my comment for some updates. I've backed away from the 1080p options!
