DO you know 2k 144hz monitors under 401$?

1. I'd be hesitant to recommend a monitor w/o knowing if ya card was G-Sync or Freesync and what card you were using. For example, the Acer XG270HU fits your criteria but it's a Freesync monitor so would recommend only if you had a Freesync compatible AMD card.

2. I don't recommend monitors from AOC
