I can't stress the importance of a good monitor enough. While my MacBook's beautiful 16" screen serves me well on the go, it can't compare to plugging into the massive 34" workstation that defines my office.
And it isn't just big—it's fast and ultra-responsive. The 144hz refresh rate pairs beautifully with the MacBook Pro's ProMotion 120hz. If you haven't used a fast refresh-rate monitor before, you won't want to go back.
It also comes with an excellent warranty. If anything happens to it within the first year, AOC will fix it no-questions-asked (I would know because I broke mine when repainting my room).
