Acer Predator XB273K 27-inch 4K monitor | $116 off
The Predator includes 4K pixel resolution, an IPS panel for color accuracy and viewing angles, a 144Hz refresh rate, and adaptive sync that includes Nvidia G-Sync compatibility. This price is also an insane discount if you don't mind getting it refurbished.
Acer promises the monitor has been refurbished by an approved vendor and functionally it's as good as new. You might notice some light use, but the monitor will probably look and feel like new. Honestly the biggest concern with a purchase like this is a dead pixel or a group of them showing up when you first turn it on. In that case, though, Acer has great customer support and should be able to help you.
The specifications for this screen are outstanding for the price. It's an IPS panel, which means it has great color accuracy and viewing angles. It has a 3840 x 2160 pixel resolution, so you can game or watch your favorite media in 4K. The display also has a native refresh rate of 120Hz and can be overclocked to 144Hz using DisplayPort.
Adaptive sync is a technology that allows you to reduce screen tearing with the power of your graphics card. In this case it has AMD FreeSync by default, but it is also compatible with Nvidia G-Sync. Using G-Sync requires you to have a 20xx or 30xx series card and requires you to connect via DisplayPort, which seems to be the way to go to get the most out of this monitor anyway.
In addition to two DisplayPort 1.4 connections, it also has two HDMI v2.0 ports and four USB 3.0 ports. That's a nice hub that makes it easy to connect peripherals. The wings around the sides are meant to help with immersion, keeping distracting things out of your vision. They are optional, though.
