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		26.5-inch (67.32 cm) OLED, 2560 × 1440 (16:9); 0.2292 mm pixel pitch; 1.07 billion colours

Because self-lit OLED pixels can switch fully off, blacks are true black; LG gives typical contrast as 1,500,000:1. 1.07 billion colours corresponds to 10-bit colour depth.

LG
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.

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.

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		2 × HDMI 2.1, 1 × DisplayPort 1.4 (DSC)

DSC (Display Stream Compression) uses visually lossless compression to fit a 1440p 240 Hz signal within DisplayPort 1.4 bandwidth. The HDMI 2.1 inputs support VRR on consoles. There is no USB-C video input.

LG
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		1 × USB 3.0 upstream, 2 × USB 3.0 downstream; 4-pole headphone output (sound + mic) with DTS Headphone:X; optical digital audio out (S/PDIF)

There are no built-in speakers. DTS Headphone:X gives virtual 3D audio over headphones.

LG
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.

Warranty3 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.

MSI		—
Refresh rate and response time—240 Hz; 0.03 ms (GtG)

240 Hz shows 240 frames per second, making motion smoother and less blurred in fast games; this needs a graphics card producing 240 fps and a DisplayPort or HDMI 2.1 connection. GtG is the time a pixel takes to change from one grey level to another.

LG
Brightness—Typical 200 cd/m², minimum 160 cd/m²

These are full-screen SDR figures; small HDR highlights can be brighter. LG does not give a peak HDR figure in the spec table.

LG
Colour and HDR—98.5% DCI-P3 (typical), 90% (minimum); HDR10; factory calibrated; hardware calibration ready

Hardware calibration uses LG Calibration Studio and a compatible colorimeter to adjust the monitor’s own colour tables. No VESA DisplayHDR certification is listed.

LG
Adaptive sync and gaming—NVIDIA G-SYNC Compatible, AMD FreeSync Premium, VRR; Black Stabiliser, Dynamic Action Sync, crosshair, FPS counter

Adaptive sync matches the monitor’s refresh to the graphics card’s frame rate to reduce tearing and stutter. Dynamic Action Sync is meant to reduce input lag.

LG
Lighting and remote—Hexagon Lighting on the back; remote control included LG
Power—External adapter, AC 100–240 V; typical 74 W, maximum 94 W; under 0.5 W in sleep LG
