Panel26.5-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.

MSI		26.5-inch WOLED; 2560 × 1440 (16:9); 0.229 mm pixel pitch; anti-glare surface

WOLED is LG Display’s panel type using a white OLED layer with colour filters; each pixel makes its own light, so blacks go fully dark. Long-lasting static images raise the risk of burn-in.

ASUS
Refresh rate240 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 time0.03 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 HDRSDR 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		—
Colour10-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		DCI-P3 99%; sRGB 135%; factory pre-calibration report ASUS
Contrast and viewing angle1,500,000:1 (typical); 178° / 178° MSI—
Inputs2 × 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		1 × DisplayPort 1.4 DSC; 2 × HDMI 2.0; headphone jack; 2 × USB 3.2 Gen 1 Type-A hub

DSC (Display Stream Compression) compresses the signal without visible loss so DisplayPort 1.4 has enough bandwidth for high refresh rates. There are no speakers and no USB-C input.

ASUS
PiP / PbPPicture-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.

OLED care and coolingMSI 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.

Refresh rate and response—240 Hz (DisplayPort); 120 Hz over HDMI; 0.03 ms (GtG)

240 Hz is only available through the DisplayPort input; ASUS’s signal table limits the HDMI inputs to 120 Hz. For PC games above 120 Hz, use a DisplayPort cable.

ASUS
Brightness and contrast—HDR peak 1,000 cd/m²; contrast 1,500,000:1; 10-bit (1.07 billion colours)

Peak brightness applies to a small part of the screen; with a full white screen brightness drops noticeably. ASUS notes peak brightness may vary with colour pre-calibration.

ASUS
HDR—HDR10

Dolby Vision and HDR10+ support are not listed.

ASUS
Variable refresh—VESA AdaptiveSync Display 240Hz; AMD FreeSync Premium; G-SYNC Compatible

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