Our take on the MSI MAG401QR 40" UWQHD 21:9 Widescreen Gaming LCD Monitor

The MSI MAG401QR is a 40-inch ultrawide gaming monitor with a 3440x1440 IPS panel, a 155 Hz refresh rate and a 1 ms response time. Its size sits between the common 34-inch ultrawides and the much larger 49-inch super-ultrawides, so it gives more screen than a 34-inch without the desk footprint of a 49-inch. The IPS panel and 1.07 billion color support suit both games and mixed desktop work, and PIP/PBP modes let you show two sources at once. Buyers rate it well overall, though a few note that a 40-inch 3440x1440 panel has a lower pixel density than smaller ultrawides, so text looks less sharp up close.

Questions and answers

Is the MSI MAG401QR good for gaming?
Yes. It pairs a 155 Hz refresh rate with a 1 ms response time and a wide 21:9 view, which suits fast games. The IPS panel also keeps colors consistent from side angles.
How does it compare with a 34-inch ultrawide?
It is bigger and more immersive, but the same 3440x1440 resolution is stretched over more area, so pixel density is lower and text is less sharp. A 34-inch is crisper; this one is larger.
Does it work for work as well as games?
Yes. The wide screen fits several windows side by side, and PIP/PBP modes let you show two inputs at once. Text is readable but not as crisp as on a smaller high-density panel.
What connections does it have?
It offers multiple connectivity options, and PIP/PBP modes work across the inputs. Check the port list for the specific HDMI and DisplayPort versions you need.
What is in the box?
The monitor ships with its stand and cabling as listed by the seller. A 2-year limited warranty covers the panel.
Do I need a deep desk for it?
Yes. A 40-inch ultrawide is wide and needs a deep desk or a monitor arm rated for its weight to sit at a comfortable viewing distance.
Where is the MSI MAG401QR 40" UWQHD 21:9 Widescreen Gaming LCD Monitor cheapest?
At Newegg.com, for $399.99, as of our latest check.
What do buyers say about the MSI MAG401QR 40" UWQHD 21:9 Widescreen Gaming LCD Monitor?
Rated 4.2 out of 5 from 13 ratings.
