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; 2560 × 1440 (WQHD), 16:9; anti-reflection surface

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 turn fully off.

Refresh and response280 Hz; 0.03 ms (GtG) LG—
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.

LG		—
Contrast and colour1,500,000:1; DCI-P3 99.5%; 1.07 billion colours

The monitor is factory calibrated and ready for hardware calibration.

Refresh rate—240 Hz; Adaptive-Sync 48–240 Hz; 2560 × 1440 at 240 Hz over DisplayPort 1.4a, both HDMI 2.1 ports and USB-C (DP Alt)

240 Hz shows 240 frames per second for smooth, clear motion in fast games, provided the graphics card can produce that frame rate. Adaptive-Sync matches the display’s refresh to the card’s frame rate to prevent tearing.

MSI
Response time—0.03 ms (GtG)

This is grey-to-grey transition time; OLED’s very fast transitions reduce motion blur, but it is not the same as total input lag.

MSI
Brightness and HDR—SDR 250 nits (typical); HDR 450 nits at 10% window and 1000 nits peak at 3% window; VESA DisplayHDR True Black 400

OLED brightness falls as the lit area grows; 1000 nits appears only in very small bright highlights. True Black 400 certifies deep blacks with at least 400 nits HDR performance.

MSI
Colour—10-bit (1.07 billion colours); 99.1% DCI-P3 and 100% sRGB coverage (CIE 1976); ΔE ≤ 2

The wide gamut gives saturated colour in HDR and games; MSI states colour accuracy as ΔE ≤ 2.

MSI
Contrast and viewing angle—1,500,000:1 (typical); 178° / 178° MSI
Inputs—2 × HDMI 2.1 (HDCP 2.3), 1 × DisplayPort 1.4a, 1 × USB-C (DP Alt, 15 W PD), headphone out

The HDMI 2.1 inputs support WQHD 240 Hz on consoles at 48 Gbps (Console Mode). USB-C with 15 W only charges small devices such as phones and is not enough to charge a laptop; the port runs at USB 2.0 speed and there is no separate USB hub.

MSI
PiP / PbP—Picture-in-picture and picture-by-picture support

Shows two sources at once: in PiP one is a small window, in PbP the two sit side by side.

MSI
OLED care and cooling—MSI OLED Care 2.0; fanless design with graphene film and custom heatsink

OLED Care includes protection functions that reduce the risk of static images leaving marks (burn-in). With no fan, it makes no noise while running.

MSI
Warranty—3 years including OLED burn-in

Terms may vary by country.
