Release year20252025
Panel26.5-inch OLED, 4th-generation Primary RGB Tandem; 2560 × 1440 (QHD), 0.2292 mm pixel pitch

In a tandem structure light comes from more than one OLED layer; LG associates this with higher brightness and lifetime.

LG		26.5-inch flat QD-OLED; 3840 × 2160; 10-bit (1.07 billion colours)

In QD-OLED, light from a blue OLED layer is converted to red and green by quantum dots; because each pixel emits its own light, blacks switch off completely. 4K in the 27-inch class gives very sharp text at about 166 ppi.

MSI
Refresh and response280 Hz; 0.03 ms (GtG) LG240 Hz (adaptive range 48–240 Hz); 0.03 ms GtG

4K 240 Hz is reached over DisplayPort 2.1a or HDMI 2.1. 0.03 ms is pixel transition time, not total input lag.

MSI
BrightnessTypical 335 cd/m², minimum 300 cd/m²; up to 1500 nits peak according to LG

The peak value applies to a small part of the screen in HDR content; brightness on a full white screen is much lower.

Adaptive sync—G-SYNC Compatible; AMD FreeSync Premium Pro

Matching refresh rate to the GPU frame rate reduces tearing and stutter.

MSI
Brightness and HDR—SDR 250 nits; HDR 450 nits at 10% APL, 1000 nits peak at 3% APL; DisplayHDR True Black 400

1000 nits is reached only when a very small part of the screen is bright; OLED brightness drops markedly on a full white screen. True Black 400 is the VESA tier for OLEDs that also measures black level.

MSI
Colour and contrast—DCI-P3 99%, Adobe RGB 98%, sRGB 138% (CIE 1976); 1,500,000:1 typical contrast

138% of sRGB means the panel can oversaturate standard content; use the sRGB mode for accurate colour.

MSI
Video inputs—1 × DisplayPort 2.1a (UHBR20); 2 × HDMI 2.1 (UHD 240 Hz); 1 × USB-C (DP Alt Mode, 98 W PD)

UHBR20 offers 80 Gbit/s, enough to carry 4K 240 Hz 10-bit without compression, provided the GPU also supports DP 2.1 UHBR20. USB-C delivers video, data and up to 98 W laptop charging over one cable.

MSI
USB and audio—2 × USB-A 5 Gbit/s; 1 × USB-B 5 Gbit/s (upstream); headphone out; no built-in speakers MSI
KVM and multi-view—KVM; PiP and PbP

KVM shares a keyboard and mouse connected to the monitor between two computers. PiP shows one source in a small window, PbP shows two sources side by side.

MSI
Warranty—3 years, including OLED burn-in

Coverage and duration may vary by country.
