Good monitors you know about?

[Vompt]

Hi everyone, I'm currently building myself a new PC and right now, I'm kind of hesitant of which monitor to choose from. I want one that has great color accuracy but still won't break my budget. I'm looking at the 200$-600$ range. Any suggestions?

I'm pin down a few that I'm currently looking into and I want to know what you guys think:

-Asus PB278Q 27.0"

-Dell U2413

-Dell U2412M

Which one you think is best? Or, do you know any better monitor?

Thank you for you help guys!
