40-inch 21:9 UWQHD gaming monitor

The MSI MAG401QR is a 40-inch ultrawide display built for immersive gaming. Its 3440 x 1440 resolution and 21:9 aspect ratio expand the field of view in supported titles. A 155Hz refresh rate and 1ms MPRT response time target fast-paced competitive play. The flat IPS panel covers wide viewing angles for consistent colour.

Suited for ultrawide enthusiasts.

This monitor suits players who value horizontal space for simulation, strategy or multi-window workflows. The 40-inch width demands significant desk depth and a graphics card able to drive 3440 x 1440 at high frame rates. Users preferring higher pixel density, curved screens or dedicated console HDMI 2.1 features should consider other models.

155Hz refresh rate with 1ms MPRT

The single spec that decides fit is the 155Hz refresh rate paired with a 1ms MPRT response time. It determines whether motion clarity matches competitive expectations on a 3440 x 1440 panel. Verify your GPU can sustain such frame rates in the games you play before purchasing.
