New Monitor

I was looking into buying a new monitor and wanted to try out 1440p but the brand name ones are pretty expensive so I was wondering which of the Korean brands do you recommend. A good response time would be a plus. I was also looking at the Asus pb278q too, it seems like the only big brand that makes an affordable monitor. If I were to buy the Asus though it'd be one of the amazon warehouse ones that are under $500

Logan did a video about a monitor from a company named X-Star for a monitor that either 1440p or 1600p (can't remember). They'll be fairly basic, probably no OSD, but they'll be cheap and work well.
