A choice you won’t regret
Incredible monitors, bought 2 of them to place side by side. I didn’t use these for gaming, it’s for my work setup in office. The resolution allows you to comfortably get multiple screens on each monitor simultaneously. Lots of built in settings and customization choices to tailor your experience. Screens are bright with color that rivals my previous flat screen IPS setup. MSI delivers another good product!

I love this monitor!
I had a 1080p curved for a few years and upgraded to this one. I love the 1440p! My games pop. Color is true. Brightness is great. Gaming performance is top notch for my MSI 5070 Vanguard. A great gaming monitor for the money. It comes with an included DP cord.
