Gigabyte MO27Q28GR 27" OLED

This monitor is plenty fast enough for the comfortable majority of gamers. If you're super serious about online shooters, well, you know who you are and lower latency is certainly available at this price point. That's obvious enough. For everyone else, this monitor has to be close to where it's at if you're looking for a vaguely sensible money 1440p OLED gaming monitor with the latest panel tech. It's really pretty sweet.
