MSI MAG 401QR 40 Inch 155Hz 1ms IPS UWQHD Ultrawide Gaming Monitor:
The MSI MAG 401QR 40 Inch 155Hz 1ms IPS UWQHD Ultrawide Gaming Monitor is designed to provide an incredibly immersive and competitive gaming experience. With its expansive ultrawide display, high refresh rate, and rapid response time, it’s a powerful choice for gamers and users who value a wide, detailed visual workspace.
Key Features for Immersive Gaming and Productivity:
This monitor boasts a large 40-inch IPS panel with a UWQHD (3440×1440) resolution and a 21:9 aspect ratio. This ultrawide format significantly enhances your field of view in games, providing a more immersive experience, and offers ample screen real estate for multitasking and productivity. The IPS panel ensures vibrant, accurate colors and wide 178° viewing angles with minimal color shift.
For fluid and responsive gameplay, the MAG 401QR features a blazing-fast 155Hz refresh rate (achieved via DisplayPort overclocking; native is 144Hz) and a rapid 1ms (MPRT) response time. This combination virtually eliminates motion blur and ghosting, giving you a competitive edge in fast-paced genres like FPS, racing, and real-time strategy games.
The monitor supports AMD FreeSync Premium, which synchronizes the display’s refresh rate with your GPU’s frame rate to eliminate screen tearing and stuttering, ensuring a smooth visual experience. It also supports VESA DisplayHDR 400, offering improved contrast and a wider color range for more vivid and realistic visuals.
Connectivity is versatile, including two HDMI 2.0b ports (supporting 3440×1440@100Hz), one DisplayPort 1.4a (supporting 3440×1440@155Hz), and a Type-C port with DisplayPort Alt Mode and 65W Power Delivery, allowing for single-cable solutions for compatible laptops. It also features a USB 2.0 hub (2x Type-A, 1x Type-B Upstream, 1x Type-C with 65W PD) and a headphone out jack.
Additional gaming-centric features include Night Vision (a smart black tuner to brighten dark areas), Anti-Flicker Technology, and Less Blue Light for reduced eye strain during extended gaming sessions. The monitor also supports Picture-in-Picture (PIP) and Picture-by-Picture (PBP) functions, along with an integrated KVM switch, enabling control of multiple devices with a single keyboard and mouse.
