The AOC CU34G2X is a great ultrawide gaming monitor. It has a 144Hz panel with native FreeSync variable refresh rate (VRR) support and G-SYNC compatibility to reduce screen tearing. It has low input lag, and although it has a quick overall response time, there's visible black smearing, which is typical of VA panels. Speaking of which, it has a high native contrast ratio, but that means it has narrow viewing angles, so it's not ideal for co-op gaming. The 34 inch screen and 3440x1440 resolution help deliver an immersive gaming experience, and it has a fairly aggressive 1500R curve to bring the edges of the screen within your field of vision.
