Panel—49-inch QD-OLED; 5120 × 1440 (DQHD), 32:9; 1800R curve

The 32:9 ratio gives a workspace equivalent to two 27-inch 1440p monitors side by side. The 1800R curve keeps the edges closer to the eyes.

MSI
Refresh and response—144 Hz (adaptive range 48–144 Hz); 0.03 ms (GtG)

Adaptive sync prevents tearing while the frame rate stays between 48 and 144. Reaching 144 fps at full resolution needs a very powerful graphics card.

MSI
Brightness and contrast—Typical SDR 250 nits; 1,500,000:1; DisplayHDR True Black 400

True Black 400 is the OLED-class certification for very low black level and 400-nit HDR brightness.

MSI
Adaptive sync—AMD FreeSync Premium Pro

The Premium Pro tier includes low frame rate compensation and low-latency tone mapping in HDR.

MSI
Connections—1 × DisplayPort 1.4a; 2 × HDMI 2.1; 1 × USB-C (DP Alt Mode, 90 W PD); 2 × USB 2.0 Type-A; 1 × USB 2.0 Type-B; headphone out

USB-C takes video from a laptop over one cable and charges it at up to 90 W. The USB ports run at USB 2.0 speed; there are no built-in speakers.

MSI
Multi-view—PiP / PbP

PbP splits the 49-inch screen side by side between two sources to show two computers at once; PiP shows one source in a small window over the other.
