The Predator CG437K S is Acer's new king. The CG437K S features a 42.5-inch NVIDIA G-SYNC Compatible UHD (3840x2160) display with an HDMI 2.1 port, which is essential if you want to use this with the latest Xbox Series S|X. That port also lets you run 4K 144 Hz (1 ms response) with variable-refresh rate (VRR) using only a single cable.

There are a few ports, too, including a full USB hub for USB Type-B, a pair of both USB 2.0 and USB 3.0 ports, plus a USB Type-C (PD30W). There's even a built-in KVM ("keyboard, video and mouse") switch that simplifies the lives of those who juggle two multiple PCs.

Like the CG437K S this monitor is packed full of unique Acer tech:

Predator Game Mode offers players eight pre-set (customizable) display modes to suit different genres of content, while Acer LightSense and Acer ColorSense make automatic adjustments to screen brightness and color temperature based on the environment. NVIDIA G SYNC Esports Mode is a display preset designed for competitive gaming that ensures the lowest possible latency by turning off variable backlight and makes it easier to distinguish objects in dark areas by increasing black levels and fine tuning gamma levels.The Predator X38 S also includes the NVIDIA Reflex Latency Analyzer, a revolutionary system latency measurement tool that detects clicks coming from the mouse and then measures the time it takes for the resulting pixels (i.e., a gun muzzle flash) to change on-screen, while NVIDIA G-SYNC ULTIMATE enables smooth, fast-paced gameplay by eliminating screen tearing, minimizing display stutter and cutting down on input lag.

The Predator X38 S will be available in North America in September, starting at USD 1,999.99; in EMEA in September starting at EUR 2,199; and in China in August, starting at RMB 14,999.
