Panel26.5-inch (27-inch class) QD-OLED, 16:9, anti-reflection surface

QD-OLED pairs self-emitting pixels with a quantum-dot colour layer; each pixel switches off individually, so blacks are fully dark.

ASUS		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.

Resolution and refresh3840 × 2160, 240 Hz

The 4K 240 Hz signal travels over DisplayPort 1.4 with DSC compression, or over HDMI 2.1 depending on graphics-card support.

ASUS		—
Response time0.03 ms (GtG)

This is the grey-to-grey pixel transition time, not total input lag.

ASUS		—
Brightness1000 cd/m² HDR peak

ASUS notes peak brightness may vary with colour pre-calibration; the peak is reached on a small screen area.

ASUS		—
Contrast1,500,000:1 (typical) ASUS—
Colour99% DCI-P3, 145% sRGB; ΔE < 2; 10-bit

Factory calibration (ΔE < 2) means colours are set close enough to target that differences are hard to see.

ASUS		—
HDRHDR10; VESA DisplayHDR 400 True Black ASUS—
Inputs1 × DisplayPort 1.4 (DSC); 2 × HDMI 2.1 (FRL); 1 × USB-C (DP Alt Mode, 90 W power)

The USB-C input takes video from a laptop and charges it at up to 90 W over one cable. HDMI 2.1 suits consoles at 4K 120 Hz.

ASUS		—
USB hub and audio3 × USB 3.2 Gen 1 Type-A; headphone jack ASUS—
Variable refreshFreeSync Premium Pro, G-SYNC Compatible; VESA AdaptiveSync Display 240 Hz

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

ASUS		—
FeaturesASUS OLED Care, KVM switch, Extreme Low Motion Blur, Neo Proximity Sensor, flicker-free

KVM shares a keyboard and mouse connected to the monitor between two computers. The proximity sensor dims the screen when the user leaves to reduce OLED wear.

Refresh and response—240 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
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.
