The Acer Predator X27U is amazing for gaming. It has a fast refresh rate that's ideal for competitive gaming, and it has FreeSync VRR and G-SYNC compatibility to reduce screen tearing. Motion looks smooth at any refresh rate thanks to its near-instantaneous response time, and it has low input lag for a responsive feel at high refresh rates. However, the input lag increases at lower refresh rates, which is disappointing for competitive gaming. While it's excellent for PC gaming, it has limited compatibility with gaming consoles because it doesn't support HDMI 2.1 bandwidth, and it doesn't support VRR with the PS5 or Xbox Series X|S either.
