Been using LG for years and always happy.
Looking for:
$600 Budget ish
32" or bigger
4K 144Hz
IPS or VA panel, something thats great for the eyes, work and play....
I should probably do that as well, I have a normal 1920x1080 super cheap one. But you know, I once had an Ultra Widescreen one and it was the freaking best for productivity, the screen was so comfortable to work in, I totally recommend. Link below to one similar I had:
BenQ monitor. I couldn't tell you exactly which one I have but I'm happy with it. You should be able to get a 4K with adjustable stand and a speaker for your budget. They do a professional series with advanced colour calibration which are more expensive again
