The MGP 491CQP stands as an expansive 49-inch ultrawide monitor with a curvature of 1800R, mirroring the curvature of a circle with an 1800mm radius. This display offers a unique 32:9 aspect ratio and boasts a resolution of 5120x1440 pixels. Its response time is also 0.3 milliseconds, and it shares the ability to present 1.07 billion colors and support 10-bit color depth. Like the others, it holds the DisplayHDR True Black 400 certification, with a refresh rate of 144Hz.

To address burn-in concerns, MSI has integrated MSI OLED Care 2.0 technology into these monitors. It's important to note that these monitors do not rely on active cooling systems but instead utilize advanced materials like graphene for effective heat dissipation. While MSI has revealed the technical specifications of these QD OLED monitors, specific release dates and pricing information remain undisclosed at this time.
