AOC AGON AG405UXC with 40″ Ultrawide IPS Panel and 144Hz Refresh Rate

AOC have recently announced the release of their new AGON gaming series display, the AG405UXC. This is a flat format 40″ ultrawide display with a 21:9 aspect ratio, 3440 x 1440 resolution and a 144Hz refresh rate. It offers an interesting larger sized option than common 34″ sized screens with this resolution, for those who want a larger screen to increase immersion, or are sitting at a further viewing distance perhaps for gaming.
