Get 27BK85U-W if you don't need speakers.
It's the business version of 27UK850-W. Differences are
No speakers. No USB 3.1.
Peak 450 nits. (A little better HDR)
3-Year warranty (5-year with Amex) vs. 1-Year warranty (2-year with Amex).
Everything else is the same (Type-C, Freesync, etc). Better for most people
especially warranty. Currently $420 on newegg.
