Panel31.5-inch flat QD-OLED; 3840 × 2160; 0.1814 mm pixel pitch; anti-reflection surface

QD-OLED converts blue OLED light to red and green with quantum dots; because each pixel makes its own light, blacks can switch fully off. 4K at 32 inches gives roughly 140 ppi.

MSI		34.18-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
Refresh and response240 Hz (48–240 Hz variable range); 0.03 ms GtG

MSI says 240 Hz at 4K is reachable over DisplayPort 1.4a, HDMI 2.1 and USB-C alike. 0.03 ms is grey-to-grey transition time, not total input lag.

MSI		240 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
Brightness and HDR250 nits typical; DisplayHDR True Black 400; 1,500,000:1 typical contrast

DisplayHDR True Black 400 is the VESA class for displays that can produce deep blacks such as OLED; it requires 400-nit small-area brightness and a very low black level. 250 nits is the full-screen SDR figure.

MSI		250 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); 99% DCI-P3, 97% Adobe RGB, 138% sRGB

138% sRGB means the gamut extends well beyond sRGB; use the monitor’s sRGB mode so sRGB content does not look oversaturated.

MSI		10-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
Adaptive syncG-SYNC Compatible; AMD FreeSync Premium Pro

Adaptive sync matches the display refresh to the game’s frame rate to reduce tearing and stutter. FreeSync Premium Pro adds a low-latency requirement in HDR.

Inputs1 × 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

The USB-C input can carry video and charge a laptop at up to 90 W over a single cable. Display Ninja says the monitor has a built-in KVM; the USB-A ports run at USB 2.0 speed.

Variable refresh—G-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.

MSI
Video inputs—1 × 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 audio—2 × 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-view—Built-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.
