Release year20242024
Panel26.5-inch (67.3 cm) OLED; 2560 × 1440; 16:9; 0.2292 mm pixel pitch

Although sold in the 27-inch class, the viewable diagonal is 26.5 inches. OLED lights each pixel itself, so there is no backlight bleed.

LG		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
Speed240 Hz; 0.03 ms (GtG) response time

GtG is the time a pixel takes to change from one grey level to another; lower values reduce motion blur.

LG		—
Brightness and contrast275 nits typical, 250 nits minimum; contrast 1,500,000:1 typical, 1,200,000:1 minimum

LG quotes 275 nits for a full-white screen (100% average picture level); small bright areas can be brighter.

LG		—
ColourDCI-P3 98.5% typical (90% minimum, CIE1976); 1.07 billion colours; factory calibrated; hardware calibration ready

A printed calibration report is included. Hardware calibration uses LG Calibration Studio with a compatible meter.

LG		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
HDR and syncHDR10; VESA DisplayHDR True Black 400; NVIDIA G-SYNC Compatible; AMD FreeSync Premium Pro; VRR

Variable refresh rate matches the monitor to the graphics card’s frame rate, reducing tearing and stutter.

LG		—
ConnectionsHDMI 2.1; 1 × DisplayPort 1.4 (DSC); USB 3.0 (1 upstream, 2 downstream); optical audio out (SPDIF); 4-pole headphone out, DTS Headphone:X

DSC compression helps carry QHD at 240 Hz over DisplayPort 1.4. There is no USB-C video input.

Refresh and response—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 HDR—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
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.

MSI
Surface and viewing angle—Anti-reflection surface treatment; 178° / 178° MSI
Warranty—3 years, including panel burn-in

On OLED, images left static for long periods can leave permanent marks; MSI covers this risk under warranty. Terms can vary by country.
