Panel34.18-inch curved QD-OLED, 1800R; 3440 × 1440 (UWQHD), 21:9; 0.2315 mm pixel pitch

1800R is the curve of a circle with a 1.8 m radius; it brings the edges of the wide screen closer to your eyes. The 21:9 ratio gives a wider field of view in supported games and room for two windows side by side.

MSI		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 response240 Hz (48–240 Hz variable range); 0.03 ms GtG

240 Hz is reached at full resolution over DisplayPort 1.4a or HDMI 2.1. 0.03 ms is pixel transition time, not total input lag. Below 48 fps the frame rate falls outside the variable refresh range.

MSI		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 HDR250 nits typical SDR; 1,000 nits peak HDR at 3% APL, 450 nits at 10% APL; VESA DisplayHDR True Black 400; 1,500,000:1 contrast

1,000 nits is reached only on bright areas covering about 3% of the screen (explosions, sun glints); as the bright area grows, OLED automatic brightness limiting kicks in.

MSI		—
Colour10-bit (1.07 billion colours); DCI-P3 99.3%, Adobe RGB 97.8%, sRGB 139.1% (CIE 1976)

sRGB above 100% means sRGB content can look oversaturated unless shown in a clamped mode.

MSI		99% DCI-P3, 146% sRGB, 98% Adobe RGB; 10-bit (1.07 billion colours) MSI
Variable refreshG-SYNC Compatible, AMD FreeSync Premium Pro

Matching refresh to the graphics card’s frame rate reduces tearing and stutter; FreeSync Premium Pro also covers low-latency HDR operation.

Video inputs1 × DisplayPort 1.4a (3440 × 1440 240 Hz); 2 × HDMI 2.1 (UWQHD 240 Hz); 1 × USB-C (DisplayPort Alt Mode, 98 W Power Delivery)

USB-C takes video from a laptop over one cable and charges it at up to 98 W; the PD charging option must be enabled in the OSD. The USB-C data path runs at USB 2.0 speed.

MSI		—
USB and audio2 × USB 2.0 Type-A, 1 × USB 2.0 Type-B (upstream); headphone out; no built-in speakers

The USB-A ports are for low-speed devices like keyboard and mouse; they are not suited to external SSDs.

MSI		—
KVM and multi-viewBuilt-in KVM; PiP (picture-in-picture) and PbP (picture-by-picture)

KVM shares the keyboard and mouse attached to the monitor between two computers; switching is done via the USB option in the OSD. PbP splits the screen between two sources, PiP shows one in a small window.

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.
