Display Quality and Performance
MSI specifies a QD-OLED panel, 1700R curvature and DisplayHDR True Black 400 certification. The curve is a defining feature, so consider your seating distance and whether you prefer a curved screen for work as well as games.
The 31.5-inch display has a native 3840 × 2160 resolution. Reaching high frame rates at 4K depends on your computer and the game or content you run.
MSI rates the panel for up to 240Hz and 0.03ms GtG response time. These are specifications, not independent measurements; your connection, settings and hardware determine the experience.
Connectivity and Dimensions
MSI lists two HDMI 2.1 ports, one DisplayPort 1.4a and a USB-C port with DisplayPort Alt Mode and up to 98W power delivery. Check that your device and cable support the mode you want.
With its stand, MSI lists the monitor at 714 × 318 × 473 mm (W × D × H). Allow room for the 1700R curve, base and comfortable viewing distance; a VESA 100 × 100 mm mount is also supported.
Ideal Use Cases
A curved 31.5-inch 4K display and 240Hz rating make this an option for gaming setups that prioritize immersion and high refresh rates. Getting the full benefit requires compatible hardware.
For color-sensitive work, review MSI’s color-gamut and calibration details rather than assuming that the QD-OLED panel alone guarantees your preferred accuracy.
