This 27-inch 1440p 180Hz Acer monitor is down to $200 at Amazon.com
Acer's Nitro lineup of monitors have proven reliable in my estimation, with a unit I bought in 2019 still being used daily in 2023. There's another Nitro model discounted on Amazon US today, the XV271U. This newer Nitro model comes with a 27-inch span, 2560x1440 resolution and 180Hz refresh rate. That, combined with G-Sync/FreeSync support and a solid Fast IPS panel, make for an awesome monitor - especially at $200, following a $100 discount.
